An efficient algorithm for monitoring virtual machines in clouds
Authors: Alshamrani Sultan
Published: June 2019

Cloud computing systems consist of a pool of Virtual Machines (VMs), which are installed physically on the provider's set up. The main aim of the VMs is to offer the service to the end users. With the current increasing demand for the cloud VMs, there is always a huge requirement to secure the cloud systems. To keep these cloud systems secured, they need a continuous and a proper monitoring. For the purpose of monitoring, several algorithms are available with FVMs. FVM is a forensic virtual machine which monitors the threats among the VMs. Our formulated algorithm runs on FVM. In this paper, we formulate the Random-Start-Round-Robin algorithm for monitoring inside FVM.

Published: June 2019

Face recognition is a challenge due to facial expression, direction, light, and scale variations. The system requires a suitable algorithm to perform recognition task in order to reduce the system complexity. This paper focuses on a development of a new local feature extraction in frequency domain to reduce dimension of feature space. In the propose method, assemble of DCT coefficients are used to extract important features and reduces the features vector. PCA is performed to further reduce feature dimension by using linear projection of original image. The proposed of assemble low frequency coefficients and features reduction method is able to increase discriminant power in low dimensional feature space. The classification is performed by using the Euclidean distance score between the projection of test and train images. The algorithm is implemented on DSP processor which has the same performance as PC based. The experiment is conducted using ORL standard face databases the best performance achieved by this method is 100%. The execution time to recognize 40 peoples is 0.3313 second when tested using DSP processor. The proposed method has a high degree of recognition accuracy and fast computational time when implemented in embedded platform such as DSP processor.

Published: June 2019

This aim of this paper is to study the potential of Polyvinylidene Fluoride (PVDF) polymeric piezoelectric film as an energy harvester for daily application use. PVDF offers several advantages over other piezoelectric materials such as high chemical strength and stability, high piezoelectric properties and biocompatible. Several investigations were carried out in this project which comprises of simulation, functionality test and application test. For functionality test, the highest voltage produced for a single film PVDF is 0.368 V which charges up a capacitor to 0.219 V in one minute. The highest voltage produced by multiple PVDF films is 1.238 V by stacking 10 films of PVDF in parallel which charges up to 0.688 V in one minute. For application test, 5 pieces of PVDF films were attached to a glove to generate some voltage during fingers bending activity. The highest output voltage recorded is 0.184 V which stores 0.101 V in a capacitor after 200 times of hand bending and releasing. As a conclusion, PVDF has a good potential as an alternative energy for daily application use. Combination of PVDF energy harvester system with proper power optimization circuit will open up rooms of research opportunities in energy harvester system with promising prospect in self-powered wireless electronics devices for Internet of Things application.

Published: June 2019

Detection text from handwriting in historical documents provides high-level features for the challenging problem of handwriting recognition. Such handwriting often contains noise, faint or incomplete strokes, strokes with gaps, and competing lines when embedded in a table or form, making it unsuitable for local line following algorithms or associated binarization schemes. In this paper, a proposed method based on the optimum threshold value and namely as the Optimum Mean method was presented. Besides, Wolf method unsuccessful in order to detect the thin text in the non-uniform input image. However, the proposed method was suggested to overcome the Wolf method problem by suggesting a maximum threshold value using optimum mean. Based on the calculation, the proposed method obtained a higher F-measure (74.53), PSNR (14.77) and lowest NRM (0.11) compared to the Wolf method. In conclusion, the proposed method successful and effective to solve the wolf problem by producing a high-quality output image.

Published: June 2019

We propose a modified OFDM modulation based on multiband scheme for visible light communications (VLC) system. The method called catenated-OFDM VLC system can efficiently boost the propagation distance and combat multipath induced the inter symbol interference and inter carrier interference. Design parameters such as number of optical bands, input power, distance and data rate are varied to see their effect on the system performances. Simulation analysis is done using Optisys software Ver. 11.0. The results show that the proposed system offers a good performance at longer transmission distance of 12 m for input power of 2 dBm in case of Band=3 with 10 Gbps data rate. BER curves also indicates that the proposed system can be operated at very high data rate of 15 Gbps. This exhibits the ability of the proposed system to be one of the candidate for future optical wireless communication system.

Authors: Khalifa Othman O. , Jannati Binti Roslin Raihan , Shah Newaj Bhuiyan Sharif
Published: June 2019

Improving voice quality over wireless communication becomes a demanding feature for social media apps like facebook, whatsapp and other communication channels. Voice-over-internet protocol (VoIP) helps us to make quick telephone calls over the internet. It includes various mechanism which are signaling, controlling and transport layer. Over wireless links, packet loss and high transmission delay damage voice quality. Here VoIP quality will be measured by three main elements which are signaling protocol, audio codec and transport layer. To improve the overall voice quality, we need to combine these three elements properly to get the best score. Otherwise perceptual speech quality will not be the right tool to measure the voice quality. Here we will use Mean Opinion Score (MOS) for calculated jitter values and end to end delay. At the end, best combination of audio codec signaling protocol produced the quality speech.

Published: June 2019

The interest for compact antennas in wireless communication increase due to the portability and mobility of the communication devices. Generally, an antenna at low frequency exhibits in large physical size. This project investigates the design of an antenna at 400 MHz. The simulation of the antenna has been performed using CST MWS. Since medical applications are dealing with low frequency, it will lead to large size of antenna which brings a challenge for wireless personal area network (WPAN). It is well known that the antenna performance decreases (according to Chu’s equation) as the size of antenna decreases. Therefore, antenna miniaturization using Meander Line (ML) will be taking place to overcome the challenges. Thus, this paper presents a comparison between i) printed dipole antenna without meander line technique, ii) printed dipole with meander line technique and iii) printed monopole antenna with meander line technique. The results show that an estimation of reduction size by 50% can be achieved using Meander Line technique.
A Game theoretic approach for competition over visibility in social networks
Authors: Touya Khadija , Baslam Mohamed , Ayachi Rachid El , Jourhmane Mostafa
Published: June 2019

Social Networks have known an important evolution in the last few years. These structures, made up of individuals who are tied by one or more specific types of interdependency, constitute the window for members to express their opinions and thoughts by sending posts to their own walls or others' timelines. Actually, when a content arrives, it's located on the top of the timeline pushing away older messages. This situation causes a permanent competition over visibility among subscribers who jump on opponents to promote conflict. Our study presents this competition as a non-cooperative game; each source has to choose frequencies which assure its visibility. We model it, exploring the theory of concave games, to reach a situation of equilibrium; a situation where no player has the ultimate ability to deviate from its current strategy. We formulate the named game, then we analyze it and prove that there is exactly one Nash equilibrium which is the convergence of all players' best responses. We finally provide some numerical results, taking into consideration a system of two sources with a specific frequency space, and analyze the effect of different parameters on sources' visibility on the walls of social networks.

A descrição é tributária de uma pesquisa-ação e tem base na observação sistemática dos encontros de formação continuada em 2016. Ao resgatar os conceitos de narrativa e comunicação, além do processo de mediação, observamos que os professores demonstram reconhecer e refletir tais conceitos na medida em que estes são problematizados em práticas pedagógicas possíveis de serem experimentadas no cotidiano escolar.
Escolas radiofônicas anunciam uma educação regionalista
Authors: Souza Kelma Fabíola Beltrão
Published: June 2019

Este artigo teve como objetivo mostrar o que foi regularmente anunciado nas escolas radiofônicas do Movimento de Cultura Popular de Recife/MCP (1960-1964), através do seu material pedagógico: o Livro de Leitura para Adultos. Pretendeu também mostrar os acontecimentos discursivos presentes na efetivação do MCP: questões sobre municipalização enfatizadas na LDB (Lei de Diretrizes e Bases da Educação); “adequação regional” proposta por Anísio Teixeira e a efetivação do Centro Regional de Pesquisas Educacionais do Recife, dirigido por Gilberto Freyre; formulação de uma identidade nacional, com características regionais. Observando o que foi regular no discurso, como nos orienta Michel Foucault, o estudo concluiu que o Livro de Leitura para adultos/escolas radiofônicas trazem ecos das práticas regionalistas almejadas por Gilberto Freyre, ou seja, a constituição de um povo genuíno e autêntico que precisava ser alfabetizado.

Published: June 2019

Background:

Thoracic aortic dissection is an emergent life-threatening condition. Routine screening for genetic variants causing thoracic aortic dissection is not currently performed for patients or family members.

Methods:

We performed whole exome sequencing of 240 patients with thoracic aortic dissection (n=235) or rupture (n=5) and 258 controls matched for age, sex, and ancestry. Blinded to case-control status, we annotated variants in 11 genes for pathogenicity.

Results:

Twenty-four pathogenic variants in 6 genes (COL3A1, FBN1, LOX, PRKG1, SMAD3, and TGFBR2) were identified in 26 individuals, representing 10.8% of aortic cases and 0% of controls. Among dissection cases, we compared those with pathogenic variants to those without and found that pathogenic variant carriers had significantly earlier onset of dissection (41 versus 57 years), higher rates of root aneurysm (54% versus 30%), less hypertension (15% versus 57%), lower rates of smoking (19% versus 45%), and greater incidence of aortic disease in family members. Multivariable logistic regression showed that pathogenic variant carrier status was significantly associated with age <50 (odds ratio [OR], 5.5; 95% CI, 1.6–19.7), no history of hypertension (OR, 5.6; 95% CI, 1.4–22.3), and family history of aortic disease (mother: OR, 5.7; 95% CI, 1.4–22.3, siblings: OR, 5.1; 95% CI, 1.1–23.9, children: OR, 6.0; 95% CI, 1.4–26.7).

Conclusions:

Clinical genetic testing of known hereditary thoracic aortic dissection genes should be considered in patients with a thoracic aortic dissection, followed by cascade screening of family members, especially in patients with age-of-onset <50 years, family history of thoracic aortic disease, and no history of hypertension.
Validation of Genome-Wide Polygenic Risk Scores for Coronary Artery Disease in French Canadians
Authors: Wünnemann Florian , Sin Lo Ken , Langford-Avelar Alexandra , Busseuil David , Dubé Marie-Pierre , Tardif Jean-Claude , Lettre Guillaume
Published: June 2019

Background:

Coronary artery disease (CAD) represents one of the leading causes of morbidity and mortality worldwide. Given the healthcare risks and societal impacts associated with CAD, their clinical management would benefit from improved prevention and prediction tools. Polygenic risk scores (PRS) based on an individual’s genome sequence are emerging as potentially powerful biomarkers to predict the risk to develop CAD. Two recently derived genome-wide PRS have shown high specificity and sensitivity to identify CAD cases in European-ancestry participants from the UK Biobank. However, validation of the PRS predictive power and transferability in other populations is now required to support their clinical utility.

Methods:

We calculated both PRS (GPS
CAD
and metaGRS
CAD
) in French-Canadian individuals from 3 cohorts totaling 3639 prevalent CAD cases and 7382 controls and tested their power to predict prevalent, incident, and recurrent CAD. We also estimated the impact of the founder French-Canadian familial hypercholesterolemia deletion (
LDLR
delta >15 kb deletion) on CAD risk in one of these cohorts and used this estimate to calibrate the impact of the PRS.

Results:

Our results confirm the ability of both PRS to predict prevalent CAD comparable to the original reports (area under the curve=0.72–0.89). Furthermore, the PRS identified about 6% to 7% of individuals at CAD risk similar to carriers of the
LDLR
delta >15 kb mutation, consistent with previous estimates. However, the PRS did not perform as well in predicting an incident or recurrent CAD (area under the curve=0.56–0.60), maybe because of confounding because 76% of the participants were on statin treatment. This result suggests that additional work is warranted to better understand how ascertainment biases and study design impact PRS for CAD.

Conclusions:

Collectively, our results confirm that novel, genome-wide PRS is able to predict CAD in French Canadians; with further improvements, this is likely to pave the way towards more targeted strategies to predict and prevent CAD-related adverse events.
The Common Rhythm of Action and Perception
Authors: Benedetto Alessandro , Morrone Maria Concetta , Tomassini Alice
Published: June 2019

Research in the last decade has undermined the idea of perception as a continuous process, providing strong empirical support for its rhythmic modulation. More recently, it has been revealed that the ongoing motor processes influence the rhythmic sampling of sensory information. In this review, we will focus on a growing body of evidence suggesting that oscillation-based mechanisms may structure the dynamic interplay between the motor and sensory system and provide a unified temporal frame for their effective coordination. We will describe neurophysiological data, primarily collected in animals, showing phase-locking of neuronal oscillations to the onset of (eye) movements. These data are complemented by novel evidence in humans, which demonstrate the behavioral relevance of these oscillatory modulations and their domain-general nature. Finally, we will discuss the possible implications of these modulations for action–perception coupling mechanisms.
“My Kingdom Lasts Forever”
Authors: Lanier Gregory R.
Published: June 2019

In the field of research on the Jewish background of NT Christology, exalted patriarchs (famous OT figures endowed with transcendent characteristics) play a prominent role. One key figure has been almost overlooked in such comparative work: Job as portrayed in the Testament of Job. As a king with a glorious heavenly throne, a position at the right hand of God, and an eternal kingdom, this Job bears a profile on par with—if not exceeding—that of other important figures in post-biblical Jewish literature (Adam, Abel, Enoch, Melchizedek, Joseph, and Moses). This study argues that Job should be added to the roster of such Jewish figures for future work on early Christology.
Jesus’s Special Knowledge in the Gospel of John
Authors: Tripp Jeffrey
Published: June 2019

The Fourth Gospel portrays Jesus as having special knowledge of himself and his future, but also of the people and events around him. While John’s Jesus always has divine insight, he does not always share it. Jesus neither shares nor hides special knowledge haphazardly, but in service of two interrelated goals: sharing special knowledge persuades doubting characters in order to build a group of believers to receive the Spirit after his death. Jesus hides special knowledge in order to ensure a proper death at his hour. In this way, John explains how a character who exerts sovereign control throughout the Gospel is nevertheless betrayed and executed.
Dynamis eis Soterian
Authors: Hauck Marion Christina
Published: June 2019

This study shows that the syntagma δύναµις εἰς σωτηρίαν was widely used in ancient Greek literature of the Classical, Hellenistic, and Greco-Roman periods. A semantic context analysis reveals that “danger” is the common intersection of all contexts in which the syntagma δύναµις εἰς σωτηρίαν occurs. In a modified way it also appears in texts of the New Testament (Rom 1:16; 1 Pet 1:5): By using δύναµις (θεοῦ) εἰς σωτηρίαν in a context focused on danger, Paul (as well as the author of 1 Peter) indicates that his use of the syntagma is consistent with the pagan, non-biblical use of δύναµις εἰς σωτηρίαν.
Putting on the New Self
Authors: Starling David
Published: June 2019

This article argues that the principal background against which the clothing metaphor in Eph 4:22, 24 would have been understood by the letter’s original hearers is that of the theater, within which changes of costume signalled changes of identity, character, or fate. After a brief survey of recent scholarly commentaries (which pay surprisingly little attention to the possibility of a theatrical background to the metaphor in these verses) it highlights instances of similar expressions within Greco-Roman theatrical contexts, both literal and metaphorical, discusses the relevant aspects of ancient dramatic theory and practice, and explores the implications of this reading for theological interpretation of Ephesians.

Published: June 2019

We developed and validated a new version of our test of temporal competency. In three studies we (1) defined dimensions, created items and studied face and content validity; (2) examined dimensionality and reliability; and (3) confirmed factor structure and studied convergent validity. Focus groups were held in which we drew up temporal concepts that articulated well with clinical observations. We derived a questionnaire that was administered to French young people and this data was used to reduce the questionnaire to 15 items. Reliability and validity of the 15-item version was studied among samples: French college, French high school, and Québec college. Five dimensions were defined and retained: anticipation, full present, temporal rupture, past, future. 15 items explained 68% of variance. The model provided adequate fit in confirmatory analyses across samples. Scales converged with hypothesized dimensions of the ZTPI and scales mostly maintained acceptable reliability. Conceptual issues with ZTPI were addressed, possibly rectified and discussed in light of clinical practice. The past was defined by how much one grows from experience independently of how ‘happy’ or ‘sad’ events were. Full present and temporal rupture relate to living in the now, the first by means of flow and engagement, the second by means of addictive behaviors. Future entailed a projection unto uncertainty, whereas anticipation defined adapting behavior in order to achieve short-term goals. We found that the questionnaire had adequate psychometric proprieties among Francophone youth in Canada and in France.

Neopuccinia, a new Pucciniales genus, based on N. bursa found on Protium heptaphyllum (Burseraceae) in the Brazilian Cerrado, is described and illustrated. The combined phylogenetic analyses of molecular data from nuc rDNA 18S and 28S markers demonstrate that the new taxon is an independent lineage and thus a taxonomically distinct unit. It is morphologically characterized by bag-like projections arising from the bicellular teliospore wall, like those found in Puccinia.
A new, localised species of purple radiate Senecio (Asteraceae: Senecioneae) from the Sneeuberg massif, South Africa
Authors: CLARK VINCENT RALPH , VIDAL JUNIOR JOÃO DE DEUS , VIDAL JUNIOR JOÃO DE DEUS , BARKER NIGEL PAUL
Published: June 2019

Senecio stella-purpurea is described as a novel species endemic to the Sneeuberg Centre of Floristic Endemism, Eastern Cape, South Africa. The species was first encountered in 2006 and erroneously identified as S. arenarius in the checklist for the Sneeuberg massif. Closer inspection of the material indicated that this is a novel species clearly distinct in southern Africa’s purple-flowered Senecio flora. Morphologically it is closest to S. glastifolius, S. umbellatus, and S. grandiflorus, but differs by the presence of pinnatisect leaves, solitary flowers, and a densely glandular hairy indumentum along its vegetative parts. Occupying approximately only 200 km2 in the eastern and western Sneeuberg, mostly above 1800 m elevation in Karoo Escarpment Grassland, the IUCN Red Listing status of VULNERABLE is proposed.

A new species of the genus Metavermilia Bush, 1905 (Annelida, Polychaeta, Serpulidae) is described from deep-water locations (1600–1700 m) off Ogasawara Islands, Japan. The genus Metavermilia is characterized by a single synapomorphy, the structure of the opercular stalk (flat and ribbon-like) formed from the second dorsal branchial radiole. The Metavermilia ogasawaraensis n. sp., is most similar morphologically to M. nanshaensis in having a simple conical operculum covered with a brownish distal plate with a tubercle in the middle and short thoracic membranes. The two species differ from each other in details of tube morphology and thoracic uncini structure. The paper provides a key and a review of all 14 species currently known in the genus Metavermilia.

The limits of polymorphism in Liolaemus rothi: Molecular and phenotypic evidence for a new species of the Liolaemus boulengeri clade (Iguanidae, Liolaemini) from boreal Patagonia of Chile
Authors: PINCHEIRA-DONOSO DANIEL , SCOLARO J. ALEJANDRO , SCHULTE II JAMES A.
Published: June 2019

Studies conducted over the last few years in Andean boreal Patagonia along the border of Argentina and Chile (36°50’S–37°53’S) have shown that its reptile diversity is comprised of several endemic lizards. Increasing research has led to recognize a number of cryptic iguanian species from previously named taxa. In this area is common the only known Chilean population of the Patagonian Liolaemus rothi, considered as a polymorphic species with wide geographical distribution. In this paper, we provide evidence to support the hypothesis that such population represents a new taxon, herein described as Liolaemus hermannunezi. This new species occurs in the southeastern areas of Laguna del Laja, in the Los Barros and Río de Los Pinos basins of Antuco Volcano (1428–1521 m) in the Bio Bio Region. Liolaemus hermannunezi is closely related to L. rothi, from which is significantly differentiated by molecular variables. In addition, this new species appears to be related to L. loboi and L. sagei, from which differs in having a smaller body size, a distinctive colour pattern and an isolated geographical distribution. Liolaemus hermannunezi is known from the boreal Patagonia of Chile, whereas L. loboi, L. rothi, and L. sagei are endemic to Argentinean Patagonia. The new species is a member of the boulengeri clade, diagnosed by the presence of a patch of abruptly enlarged scales on the posterior medial surface of the thigh, a character that is more conspicuous in adult males. Finally, a phylogenetic hypothesis for 67 Liolaemini taxa based on DNA sequences is presented
Iguanian species-richness in the Andes of boreal Patagonia: Evidence for an additional new Liolaemus lizard from Argentina lacking precloacal glands (Iguania, Liolaeminae)
Authors: PINCHEIRA-DONOSO DANIEL , SCOLARO J. ALEJANDRO
Published: June 2019

Most Liolaemus lizard species are characterized by the presence of precloacal glands in males. Only a few taxa lack these sexual signal emitter structures. Phylogenetic evidence suggests that those species are restricted to the clades chiliensis and lineomaculatus. Within the first lineage, L. coeruleus, L. cristiani, L. flavipiceus, L. neuquensis and L. thermarum lack precloacal glands, which have been considered as members of the neuquensis group. Whereas, in the second one, L. periglacialis (= L. hatcheri), L. kolengh, L. lineomaculatus, and L. silvanae exhibit this characteristic. In the present study we provide the description of Liolaemus tregenzai, an additional new species lacking precloacal glands in both sexes. This new taxon, member of the chiliensis clade, is so far known from the Copahue Volcano, Neuquén Province of Argentina, in boreal Patagonia. Liolaemus tregenzai differs from the remaining species of this clade in having a unique combination of morphologic and chromatic traits, such as a large body size, olive or chest-nut dorsal ground colour, with dark brown or blackish pigment on the flanks, green-bluish with intense black pigment on the ventral surface, and evident sexual dichromatism. The ecology of this new lizard is also remarkably, occurring in Andean antarctandic forests, and being common near thawing snows. Phylogenetic relationships of this species with other members of the chiliensis clade and with the taxa recognized as members of the neuquensis group are still unknown.
New coastal and insular species of the bromeligenous Scinax perpusillus group, from the State of Rio de Janeiro, Brazil (Anura, Hylidae)
Authors: DA SILVA HELIO RICARDO , SILVA RICARDO ALVES-
Published: June 2019

We describe a new bromeligenous species of Scinax from the perpusillus group from the Atlantic Forest of the State of Rio de Janeiro, Brazil. The new species is described from three different localities, two on the continent (Municipality of Mangaratiba), and the other on an island, Gipóia (Municipality of Angra dos Reis). The new species may be easily diagnosed from all other known species in the group by the color pattern of the tadpole, by the prominent medial process between the nostrils in adults. While in all the other species the tadpole has a uniform dark brown coloration, in the new species tadpoles is similarly dark brown, but also has a yellow stripe on the head between the nostrils and the eyes.
Laurentaeglyphea Forest, 2006 (Crustacea, Decapoda, Glypheidae): a cautionary tale of nomina nuda and the unpredictability of publication schedules
Authors: BOYKO CHRISTOPHER B.
Published: June 2019

Glypheid crustaceans have been the source of much recent discussion, particularly in a phylogenetic context (Schram & Ahyong, 2002; Dixon et al., 2003; Ahyong & O’Meally, 2004), an interest initiated by the discovery and report of a living example of this long-thought extinct group by Forest & de Saint Laurent (1975). Subsequent collections resulted in additional information about the biology, ecology, morphology, and biogeography of this “unique” living glypheid species, Neoglyphea inopinata Forest & de Saint Laurent, 1975 (Forest & de Saint Laurent, 1976; 1981; 1989; Bruce, 1988).

Three new species of Neotropical Tropisternus Solier (Coleoptera: Hydrophilidae)
Authors: SPANGLER PAUL J. , SHORT ANDREW EDWARD Z.
Published: June 2019

The water scavenger beetle genus Tropisternus Solier, 1834, is one of the most common and recognizable taxa of aquatic beetles in the New World. As presently defined, the genus contains 60 species (Hansen 1999, Short & Hebauer 2006) and ranges from northern Canada to the southern tip of South America. The senior author (PJS) conducted a full revision of this taxonomically difficult genus for his PhD dissertation nearly fifty years ago (Spangler 1960). For the next several decades, PJS continued to update, revise, correct, and incorporate new material into this massive work. This paper makes available three new names of Tropisternus in preparation for the eventual publication of this authoritative treatment of the genus. It should be noted for those using the keys given in Spangler (1960) that the interpretation of some of the names proved incorrect following the examination of types; the key should be used with extreme caution particularly for Neotropical taxa.
Redescription of Anolis rubribarbaris (Kuhler, McCranie, & Wilson 1999), a poorly-known Mesoamerican cloud forest anole (Squamata: Polychrotidae)
Authors: TOWNSEND JOSIAH H. , WILSON LARRY DAVID , LUQUE-MONTES ILEANA R. , KETZLER LORRAINE P.
Published: June 2019

Anolis rubribarbaris (Köhler, McCranie, & Wilson 1999) was described based on a single adult male specimen collected in 1994, which lacked color notes or everted hemipenes. We recently collected three additional specimens of A. rubribarbaris, one male and two females, from near the type locality in Parque Nacional Montaña de Santa Bárbara. We present a redescription of A. rubribarbaris based on this new material, which includes the first description of the hemipenis, the first description of a female, and the first description of the color in life of both sexes.

Published: June 2019

An updated checklist of cladoceran orders Ctenopoda and Anomopoda from inland aquatic habitats in Venezuela is provided, containing a total of 112 species grouped into 39 genera. Recorded cladoceran species of Venezuela represent 30% of the world’s described 370 species of Ctenopoda and Anomopoda. The most representative genera are Alona, Diaphanosoma, Moina, Macrothrix, and Chydorus with 19, 10, 7, 6, and 5 species, respectively. Most records (45%) are Neotropical and about 4% are endemic species. Some aspects related to geographical distribution and species richness in the Venezuelan hydrographic basins are briefly discussed.
First record of an early pea crab stage on Tonicia chilensis (Frembly, 1827) (Mollusca, Polyplacophora)
Authors: MELZER ROLAND R. , SCHWABE ENRICO
Published: June 2019

Pea crabs, or pinnotherids (Crustacea, Decapoda), known since Aristoteles from mussels like Pinna nobilis Linnaeus, 1758, can be found in association with various marine evertebrates, such as tunicates, tube worms, sea urchins and others. Among molluscs, they are not only found in bivalves, but also in several gastropods (see Geiger & Martin 1999). However, there is only one report to date of a pea crab-polyplacophoran association, that of Opisthopus transversus Rathbun, 1893 and Cryptochiton stelleri (von Middendorff, 1847) from the Californian coast (Webster 1968).

Published: June 2019

A well preserved female specimen of the extinct genus Microphorites Hennig, 1971 (Diptera: Dolichopodidae) is known from San Just Amber (Lower Cretaceous, Albian, East Spain) and described as M. utrillensis nov. sp. In addition, ceratopogonids from the same deposit have been recognized as specimens of Protoculicoides skalskii Szadziewski & Arillo, 1998 and Leptoconops zherikhini Szadziewski & Arillo, 2003 two species known previously in Spanish amber from Álava. The new specimens make it possible to complete and emend the original description of P. skalskii. Palaeoecological and palaeobiogeographical comments are provided.

Morphological and molecular evidence for a new species of longnose skate (Rajiformes: Rajidae: Dipturus) from Argentinean waters based on DNA barcoding
Authors: DE ASTARLOA JUAN MARTIN DÍAZ , MABRAGAÑA EZEQUIEL , HANNER ROBERT , FIGUEROA DANIEL E.
Published: June 2019

A new species of Dipturus is described from ten specimens collected off Patagonia, Argentina. Morphological and molecular approaches were used to compare among specimens of recognized Dipturus species. By comparing morphometric, meristic and mitochondrial cytochrome c oxidase I (COI) sequence data, specimens referred to as longnose skate and originally regarded as D. chilensis were shown to be a discrete species as distinguished from both the Yellownose skate, D. chilensis and the Roughskin skate, D. trachyderma. Dipturus argentinensis n. sp. can be distinguished from all other southwestern Atlantic longnose skate species by its color pattern, lack of squamation on both upper and lower surfaces of the disc, and a long, thin tail that is approximately half the total length. The new species has one median row of 10 to 24 small caudal thorns, one or two interdorsal thorns and 35 to 40, and 34 to 43 tooth rows on upper and lower jaws, respectively. The 648 base pair COI mitochondrial DNA “barcodes” derived from specimens of D. argentinensis are identical to each other and exhibit greater than 3% sequence divergence from all other Dipturus species similarly characterized to date. Taken together, these independent morphological and molecular observations serve to corroborate one another and thus provide strong evidence for the recognition of D. argentinensis as a new species.
Revision of the genus Apterodorcus Arrow (Coleoptera: Lucanidae: Lucaninae) of southern South America
Authors: E. JOSÉ MONDACA , PAULSEN M. J.
Published: June 2019

The southern South American genus Apterodorcus Arrow is revised (Coleoptera: Lucanidae: Lucaninae). The genus contains two species, A. bacchus (Hope in Westwood, 1845) and A. tristis (Deyrolle in Parry, 1870). Apterodorcus tristis is reinstated as a valid species, having previously been treated as a junior synonym of A. bacchus. Both species are redescribed and illustrated, and information on biology and geographic distribution are included.Se revisa el género Apterodorcus Arrow (Coleoptera: Lucanidae: Lucaninae) de América del Sur Austral.
