Published: June 2019

Proper narrowband antenna design for wearable devices in the biomedical application is a significant field of research interest. In this work, defected ground structure-based microstrip patch antenna has been proposed that can work for narrowband applications. The proposed antenna works exactly for a single channel of ISM band. The resonant frequency of the antenna is 2.45 GHz with a return loss of around -30 dB. The -10dB impedance bandwidth of the antenna is 20 MHz (2.442-2.462 GHz), which is the bandwidth of channel 9 in ISM band. The antenna has achieved a high gain of 7.04 dBi with an increase of 17.63% antenna efficiency in terms of realized gain by using defected ground structure. Three linear vector arrays of arrangement 1 2, 1 4 and 1 8 have been designed to validate the proposed antenna performances as an array. The proposed antenna is light weighted, low cost, easy to fabricate and with better performances that makes it suitable for biomedical WLAN applications.

The main goal of utilizing Selective Harmonic Elimination (SHE) techniques in Multilevel Inverters (MLI) is to produce a high-quality output voltage signal with a minimum Total Harmonic Distortion (THD). By calculating N switching angles, SHE technique can eliminate (N-1) low order odd harmonics of the output voltage waveform. To optimized and obtained these switching angles, N of nonlinear equations should be solved using a numerical method. Modulation index (m) and duty cycle play a big role in selective harmonic elimination technique to obtain a minimum harmonic distortion and desired fundamental component voltage. In this paper, a novel Optimization Harmonic Elimination Technique (OHET) based on SHE scheme is proposed to re-mitigate Total Harmonic Distortion. The performance of seven-level H-bridge cascade inverter is evaluated using PSIM and validated experimentally by developing a purposely built microcontroller-based printed circuit board.

Published: June 2019

Water level sensors are one of the practical ways to get the actual measurement of the depth of a dam or canal. The ease of deployment and easy data acquisition makes them widely used in many fields. Therefore, it will be advantageous to have a miniaturized water level sensor for easier mobility and deployment. A novel method for measuring water level using a Printed Circuit Board has been proposed in this paper. The design stages of circuit sketching, printing of sketch on PCB and etching are discussed for the electrode water level sensor. A signal conditioning circuit is necessary to maintain a steady flow of current from the power source. The fabricated electrode water level sensor was tested based on its capacitive effect while charging up and the amount of current at each electrode finger at the saturation stage. The hardware enablers for this test were the multimeter and LCR meter. Arduino microprocessor was used to test and measure the transient response time for each electrode finger. The transient response sensitivity of the electrode sensor is measured to be 0.0873 millisecond/cm while the resolution of the electrode sensor is 0.1cm over a range of 30cm water level. A multiple correlation of 0.921 was achieved for the water level, measured current and measured capacitance with P-values less than 0.05 indicating strength of the data obtained from the tests conducted. The result showed strong evidence that the electrode water level sensor can be an alternative method of measuring water level.

The increasing global trends in healthcare priorities towards improving the effectiveness of diagnostic procedure by utilizing a non-invasive method which is breath analysis. This will benefit in increasing treatment efficiency and also reducing healthcare costs. Breath is a simple technique where the sample are easily obtained and can be provided immediately. The most popular method that had been used in hospital are urine and blood. Contradict with breath, urine and blood take too much time to analyse the disease and a painful process. The detection technique of breath analysis is done by using electroacoustic wave sensor from piezoelectric substrate. This acoustic wave sensor has been used to detect the changes in the frequency where it will be used to detect the disease. Breath analysis is a technique where it uses an electronic nose (E-nose) as a device. E-nose consist of Quartz Crystal Microbalance (QCM) sensor in order to differentiate odor in human breath. QCM is a sensitive weighing device which have a high efficiency. AT-cut quartz was chosen as the piezoelectric material and aluminum as the electrode. The objective of this paper is to design and simulate a QCM sensor for breath analysis application. Other than that, it also to determine the important key parameters that influence the performance of breath analysis which is sensitivity and resonant frequency. QCM sensor is being simulate by using COMSOL Multiphysics software. This is to evaluate the behavior of QCM sensor in terms of Eigen frequency analysis. The simulated QCM sensor with quartz radius of 166 um resonates at 8.871 MHz. The sensitivity of the sensor is 0.167 MHz/ng after exposed to acetone gas which act as the breath marker for detection of diseases in exhaled breath. Hence, the proposed design can be used as a non-invasive approach for early detection of disease through breath analysis.

Published: June 2019

Wireless networks incorporate Mobile Nodes (MNs) that use wireless access networks to communicate. However, the communication among these MNs are not remained stable due to the poor network coverage during inter mobility. Moreover, the wireless nodes are typically small that results in resource-constrained. Thus, it is uphill to use algorithms having giant processing power or memory footprint. Accordingly, it is essential to check schemes consistently to evaluate the performance within the probable application scenario. To do so, numerical analysis could be a notable method to grasp the performance of mobility management schemes as well as the constraint of evolving mobility management solutions specifically for multi-interfaced MR in Proxy NEMO environment. This paper analyzes handoff performance by using a mathematical model of Multihoming-based scheme to support Mobility management in Proxy NEMO (MM-PNEMO) environment. Moreover, a comparative study has been made among the standard Network Mobility Basic Support Protocol (NEMO BSP), Proxy NEMO (PNEMO) and MM-PNEMO scheme respectively. The performance metrics estimated for these schemes are mainly handoff delay and packet loss. This paper also analysed the packet loss ratio and handoff gain as a function of cell radius, number of SMR and velocity respectively. It is apparent that, the MM-PNEMO scheme shows lower packet loss ratio (1%) compared to NEMO-BSP (11%) and P-NEMO (6%).

Published: June 2019

Smart street light is an intelligent control of street lights to optimize the problem of power consumption of the street, late in night. Conventional street lights are being replaced by Light Emitting Diode (LED) street lighting system, which reduces the power consumption. The focus of this project is to design a system of street lights controller to provide a reduction in power consumption. The prototype was designed by using Light Dependent Resistor (LDR), Infrared sensor (IR), battery and LED. The brightness of the lamps is being controlled in this project to reduce the power consumption. The dimming of the lamps depends on the speed of object motion detected such as pedestrians, cyclists and cars. The higher speed of moving object, the greater the level of intensity. For this idea, the innovation of street lights is not quite the same as conventional street lights that are controlled by timer switch or light sensor which automatically turns light on during sunset and off during sunrise. According to the study, motion detection devices may help to save up to 40% of energy per month.

Using Statistical Modeling to Understand and Predict Pediatric Stem Cell Function
Authors: Shoja-Taheri Farnaz , George Alex , Agarwal Udit , Platt Manu O. , Gibson Greg , Davis Michael E.
Published: June 2019

Background:

Congenital heart defects are a leading cause of morbidity and mortality in children, and despite advanced surgical treatments, many patients progress to heart failure. Currently, transplantation is the only effective cure and is limited by donor availability and organ rejection. Recently, cell therapy has emerged as a novel method for treating pediatric heart failure with several ongoing clinical trials. However, efficacy of stem cell therapy is variable, and choosing stem cells with the highest reparative effects has been a challenge.

Methods:

We previously demonstrated the age-dependent reparative effects of human c-kit+ progenitor cells (hCPCs) in a rat model of juvenile heart failure. Using a small subset of patient samples, computational modeling analysis showed that regression models could be made linking sequencing data to phenotypic outcomes. In the current study, we used a similar quantitative model to determine whether predictions can be made in a larger population of patients and validated the model using neonatal hCPCs. We performed RNA sequencing from c-kit+ progenitor cells isolated from 32 patients, including 8 neonatal samples. We tested 2 functional parameters of our model, cellular proliferation and chemotactic potential of conditioned media.

Results:

Interestingly, the observed proliferation and migration responses in each of the selected neonatal hCPC lines matched their predicted counterparts. We then performed canonical pathway analysis to determine potential mechanistic signals that regulated hCPC performance and identified several immune response genes that correlated with performance. ELISA analysis confirmed the presence of selected cytokines in good performing hCPCs and provided many more signals to further validate.

Conclusions:

These data show that cell behavior may be predicted using large datasets like RNA sequencing and that we may be able to identify patients whose c-kit+ progenitor cells exceed or underperform expectations. With systems biology approaches, interventions can be tailored to improve cell therapy or mimic the qualities of reparative cells.

Cardiovascular genetics is a rapidly evolving subspecialty within cardiovascular medicine, and its growth is attributed to advances in genome sequencing and genetic testing and the expanding understanding of the genetic basis of multiple cardiac conditions, including arrhythmias (channelopathies), heart failure (cardiomyopathies), lipid disorders, cardiac complications of neuromuscular conditions, and vascular disease, including aortopathies. There have also been great advances in clinical diagnostic methods, as well as in therapies to ameliorate symptoms, slow progression of disease, and mitigate the risk of adverse outcomes. Emerging challenges include interpretation of genetic test results and the evaluation, counseling, and management of genetically at-risk family members who have inherited pathogenic variants but do not yet manifest disease. With these advances and challenges, there is a need for specialized programs combining both cardiovascular medicine and genetics expertise. The integration of clinical cardiovascular findings, including those obtained from physical examination, imaging, and functional assessment, with genetic information allows for improved diagnosis, prognostication, and cascade family testing to identify and to manage risk, and in some cases to provide genotype-specific therapy. This emerging subspecialty may ultimately require a new cardiovascular subspecialist, the genetic cardiologist, equipped with these combined skills, to permit interpretation of genetic variation within the context of phenotype and to extend the utility of genetic testing. This scientific statement outlines current best practices for delivering cardiovascular genetic evaluation and care in both the pediatric and the adult settings, with a focus on team member expertise and conditions that most benefit from genetic evaluation.
Moral Habituation in the Law: Rethinking the Ethics of the Sharīʿa
Authors: Quadri Junaid
Published: June 2019

This essay contributes to a longstanding concern with the place of ethics in Islamic law, suggesting a reorientation of the debate through a consideration of the role of habituation in works of uṣūl and furūʿ. I demonstrate that the well-known emphasis on habituation in Aristotle’s ethics, and its underlying conception of character, exerted a heavy influence on writers of akhlāq works. I then examine the development of three fiqhī concepts – idmān, iqāma and iṣrār – to show how jurists embedded this conception of moral behavior in the discursive fiqh tradition, linking their disapproval of persistent sinful or morally distasteful behavior to a tangible legal effect: the forfeiture of the violator’s standing before the court. Based on this finding, I argue that jurists and moralists operated in a shared universe of normativity in which the commitment to habituation as a premier mode of ethical cultivation was held in common.

Similar look but different song: a new Cicadetta species in the montana complex (Insecta, Hemiptera, Cicadidae)
Authors: SUEUR JÉRÔME , PUISSANT STÉPHANE
Published: June 2019

The Cicadetta montana species complex includes six cicada species from the West-Palaearctic  region. Based on acoustic diagnostic characters, a seventh species Cicadetta cantilatrix sp. nov. belonging to the complex is described. The type-locality is in France but the species distribution area extends to Poland, Germany, Switzerland, Austria, Slovenia, Macedonia and Montenegro. The calling song sequence consists of two phrases with different echemes. This calling pattern clearly differs from those produced by all other members of the complex, including C. cerdaniensis, previously mistaken with the new species. This description increases the acoustic diversity observed within a single cicada genus and supports the hypothesis that sound communication may play a central role in speciation.
Variability of Habroblattula drepanoides gen. et. sp. nov. (Insecta: Blattaria: Blattulidae) from the Yixian Formation in Liaoning, China
Authors: WANG TIAN-TIAN , LIANG JUN-HUI , REN DONG
Published: June 2019

Habroblattula drepanoides gen. et sp. nov. (Blattulidae) is described from the Late Jurassic or Early Cretaceous sediments of the Yixian Formation in Western Liaoning, China. Wing venation of Habroblattula drepanoides reveals low coefficient of variation (CV) for total number of the forewing veins (CV=5.72) which indicates active flight capability. The higher hindwing variability (CV=14.43) might suggest Habroblattula was an advanced genus, may be caused by the regulation of the vein. The asymmetry between the left and right forewing in the same individual indicates the flight was limited when comparing with the CV of the left and right forewings.

Authors: DEMITE PETERSON R. , LOFEGO ANTONIO C. , FERES REINALDO J.F.
Published: June 2019

Phytoseiid mites have received considerable world wide attention because of their potential as natural enemies of phytophagous mites (McMurtry, 1984). The Amblyseius obtusus group Chant  is the largest species group in the genus Amblyseius. Chant & McMurtry (2004) divided the group into seven subgroups based on spermathecal morphology. The andersoni subgroup of Chant & McMurtry, 2004 is characterized by a spermatheca with the calyx dish-, cup-, bell-, or V-shaped, with the length/width ratio at the mid-point of the calyx < 3:1. A total of 24 species of the andersoni subgroup are known from the Neotropical region, 13 of these from Brazil (Moraes et al., 2004). A new species of this subgroup, Amblyseius paulofariensis sp. nov., is described and illustrated in this paper, from specimens collected in the semi-deciduous forest area of “Estação Ecológica de Paulo de Faria”, a protected natural area in the State of São Paulo, southeastern Brazil, on three species of Euphorbiaceae: Acalypha diversifolia Jacq., Actinostemon communis (Müll. Arg.) and Alchornea glandulosa Poepp. & Endl.. In the region where this mites was found, the climate is of the type Cwa-Aw of Köppen, with two distinct seasons: one wet, from October to March, and the other dry, from April to September. The annual mean temperature is 25°C, with a maximum mean of 30°C and a minimum mean of 20°C (Barcha & Arid, 1971; Arid & Barcha, 1973).

A new species of the selenopid crab-spider genus Selenops Latreille, 1819 (Araneae: Selenopidae) from Guerrero, Mexico
Authors: MONDRAGÓN ALEJANDRO VALDEZ
Published: June 2019

The spider family Selenopidae Simon, 1897 consist of four genera, of which Selenops Latreille, 1819 has about 110 species in tropical to temperate regions around the world (Platnick 2007). The distribution of this genus in America is from Argentina and Paraguay in South America, northward through tropical and subtropical America to Florida, Texas, New Mexico, Arizona, and southern California in North America (Muma 1953). These spiders can be found in different habitats, from dry desert and chaparral to tropical areas. They are typically found under rocks and other objects on the ground, occasionally inside tree trunks, and between the bases of the leaves of tropical plants. They also occur in the entrances of caves, on flat surfaces and in narrow cracks and crevices. They are commonly found inside human habitations. Their flattened body allows them to slide into these cracks with very fast movements, which makes their collection in the field difficult. They are nocturnal and do not build webs (Muma 1953).

Published: June 2019

An overview of the marine rhabdocoel fauna of Uruguay is given. Eight species, new to science, are described and discussed. Two of these, Acirrostylus poncedeleoni n.g. n.sp. and Polliculus cochlearis n.g. n.sp. could not be placed in any existing genera. A. poncedeleoni n.g. n.sp. can be recognized from other Cicerinidae Meixner, 1928 by the fact that there is only one ovovitellarium and by the lack of a cirrus in the male atrium. P. cochlearis n.g. n.sp. is characterized by the fact that there is only one testis and vas deferens, a unique situation within the Dalyelliidae Graff, 1905. Apart from these two species, six other new species are described: Cheliplana triductibus n.sp. and C. uruguayensis n.sp. (Karkinorhynchidae Meixner, 1928), Carcharodorhynchus viridis n.sp. (Schizorhynchidae Graff, 1905), Baicalellia forcipifera n.sp. (Provorticidae Beklemischew, 1928) and Vauclusia multistriata n.sp. and Coronhelmis mimosa n.sp. (Promesostomidae Den Hartog, 1964). All these species can be recognized from their congeners by the detailed structure of the genital organs in general, and the copulatory organ in particular. For four known species of Dalytyphloplanida Willems, 2006 new data are given: Ceratopera axi (Riedl, 1954) Den Hartog, 1964 (Trigonostomidae Graff, 1905), Lurus evelinae Marcus, 1950 (Luridae Sterrer & Rieger, 1990), Byrsophlebs caligulachaena (Ehlers & Ehlers, 1981) Karling, 1985 (Byrsophlebidae Graff, 1905) and Oneppus lacus Marcus, 1954 (Placorhynchidae Meixner, 1938). The occurrence of one new species of Polycystididae Graff, 1905 and the possible occurrence of Cheliplana firmata Brunet, 1968 and Proschizorhynchus atopus Marcus, 1950 are also mentioned.

Mites of the family Linotetranidae (Acari: Prostigmata) are unique among the tetranychoid families in that eyes are absent (Meyer & Ueckermann, 1997). They are usually colourless, slender and less than a third of a millimeter in length, and occur mostly in soil. Linotetranids have been reported from moss, soil and rotting trees, but most collection indicate an association with the crown and roots of grass or sedge in dryland habitats (Beard & Walter, 2004). Up to now eight species of the genus Linotetranus have been described in the world. In this paper we describe and illustrate a new species. The terminology and abbreviations follow Lindquist (1985) and all measurements are given in micrometers.

A key to the species of the genus from Nepal is presented.
A new species of Korinnis Günther from the Philippines (Phasmatodea: Prisopodidae: Korinninae)
Authors: GOTTARDO MARCO
Published: June 2019

The Philippine phasmid fauna is highly biodiverse (Hennemann & Conle 2007), but several taxonomic groups are as yet little understood. An obvious example is the superfamily Aschiphasmatoidea Brunner von Wattenwyl, 1893. Philippine representatives of this ancestral clade (Zompro 2004) fall into the Southeast-Asian subfamilies Aschiphasmatinae (Aschiphasmatidae), and Korinninae (Prisopodidae). Altogether, only nine species have been recorded from the archipelago, although some species cited by Redtenbacher (1906) and Bruner (1915) appear to be erroneous records. Zompro (2004: 90) indicates that Philippine reports of Orthomeria (Orthomeria) pandora (Westwood, 1859) and O. (O.) forstenii (de Haan, 1842) have been based on misidentifications. Additionally, Aschiphasma annulipes Westwood, 1834 is here excluded from the Philippine fauna; definite distribution records of this species include Indonesia (Kalimantan, Java and Sumatra), Malaysia, Thailand, Vietnam, and north India.
Pseudancistrus corantijniensis, a new species from the Guyana Shield (Siluriformes: Loricariidae) with a molecular and morphological description of the Pseudancistrus barbatus group
Authors: DE CHAMBRIER SOPHIE , MONTOYA-BURGOS JUAN I.
Published: June 2019

Pseudancistrus corantijniensis is described based on specimens captured in the Corantijn River in Suriname. It is diagnosed by a particular arrangement of whitish spots, very small in the anterior three quarters of the head and large from the posterior part of the head to the caudal peduncle. As indicated by our molecular phylogeny based on mitochondrial D-loop sequences, P. corantijniensis is a member of the Pseudancistrus barbatus group comprising Guyanese derived Pseudancistrus bearing hypertrophied odontodes along the snout and nonevertible cheek plates. Other members of this group are P. barbatus, P. depressus and P. nigrescens. The closest relative to the new species is P. nigrescens, while P. barbatus and P. depressus are sister species. The known distribution range of each of the four members of the P. barbatus group is disjoint. A key is provided for the identification of the four members of the P. barbatus group.
A new Pamphorichthys (Cyprinodontiformes: Poeciliidae: Poeciliini) from central Brazil
Authors: FIGUEIREDO CARLOS AUGUSTO
Published: June 2019

A new species of Pamphorichthys is described from Preto river, tributary of the São Francisco river drainage. The new species is the sister group of the remaining species of Pamphorichthys, showing synapomorphies of the genus, including the reduced number of gonapophyses and gonapophyses tips parallel to the vertebral spine. The diagnosis is given by the following unique features: outer row of teeth on pre-maxilar and dentarium with bilobed incisive teeth; distal segments of the third ray of the gonopodium and an elongated anterior branch of the fourth ray with a putative origin in the fusion of several distal segments; anterior and posterior branches of gonopodium ray 6 with distal segments fused into only one segment; six dorsal-fin rays in males; and urogenital region of reproductive females with heavy dark pigmentation all around the anus and urogenital opening.
Taxonomic consideration of eight Chinese bisexual Artemia populations, based on the morphology of frontal knob and gonopod and the result of cross-breeding tests
Authors: ZHENG BO , SUN SHI-CHUN
Published: June 2019

The taxonomic assignment of the Artemia from Qinghai-Xizang Plateau has been argued. In the present paper, the morphology of frontal knobs and gonopods of five Artemia populations from Qinghai-Xizang Plateau (Lagkor Co, Cam Co, Dagdong Co and Jibu Caka, Tibet; Jingyu Hu, Xinjiang) and three populations from North China (Badain Jaran and Yimeng, Inner Mongolia; Xiechi Lake, Shanxi) is described and compared with four non-Chinese species, the results of cross-breeding tests between the eight Chinese populations are documented and the taxonomic assignment of these Artemia populations is discussed. Morphological observations show that gonopods of the Chinese populations are significantly longer than those of the other species; distal gonopods of the Chinese populations possess spines that can be classified into three groups (posterior spines, exolateral spines and orthostichous spines). In the four non-Chinese species, however, orthostichous spines are absent (thus providing a morphological separation between A. urmiana and A. tibetiana) and the number of spines is much smaller than those of the Chinese populations. Discriminant analysis on numerical characters showed that three North China populations were divergent from four Tibetan populations, with Jingyu Hu population intermediate. Compared with the North China populations, the Tibetan populations possess a longer gonopod (longer gonopod, longer distal gonopod and longer finger-like tip), larger basal gonopod spine, larger percent of frontal knob spines that emerge by 2 spines from the same region and smaller percent of frontal knob spines that emerge by 4 and 5 spines from the same region. The Artemia from Jingyu Hu is morphometrically close to the Tibetan populations by possessing a larger basal gonopod spine, larger percent of frontal knob spines emerging by 2 spines from the same region and smaller percent of frontal knob spines emerging by 4 and 5 spines from the same region, but different from the latter by having a shorter gonopod (shorter gonopod, shorter distal gonopod and shorter finger-like tip), fewer frontal knob spines, more distal gonopod spines and more posterior spines. The results of cross-breeding tests showed that isolating barrier did not exist among the three North China populations or among the five Qinghai-Xizang Plateau populations, while they might exist between A. urmiana and the populations of Xiechi Lake (type locality of A. sinica) and Lagkor Co (type locality of A. tibetiana) and between the Qinghai-Xizang Plateau populations and A. sinica. The present results thus support the validity of A. tibetiana. Among the eight Chinese populations, the five populations from Qinghai-Tibet Plateau belong in A. tibetiana, whereas three populations from North China belong in A. sinica.
Alain raymondi, a new species of deepwater pinnotherid crab (Crustacea: Decapoda: Brachyura) from the Philippines, commensal with holothurians
Authors: AHYONG SHANE T. , NG PETER K. L.
Published: June 2019

The second species of the deepwater holothuriophilus pinnotherid genus, Alain Manning, 1998, A. raymondi sp. nov., is described from the Philippines. Alain was originally, but erroneously diagnosed as having a 6-segmented male abdomen. All species of Alain, however, have a 7-segmented abdomen in both sexes; the generic diagnosis is emended. An unusual feature of species of Alain is male androgyny, a phenomenon otherwise known among pinnotherids only from Nepinnotheres androgynous Manning, 1993b. We also take the opportunity to report the first case of male androgyny in Pinnotheres novaezelandiae Filhol, 1885, a New Zealand species that is herein transferred to Nepinnotheres. Among pinnotherids, androgynous males are now known from four species in two genera. Little is known of the biology of most pinnotherids, and androgyny may be significantly more prevalent than currently recognized.

Description of the larvae of three species of Laccophilus Leach and comments on the phylogenetic relationships of the Laccophilinae (Coleoptera: Dytiscidae)
Authors: MICHAT MARIANO C.
Published: June 2019

The larvae of three Neotropical species of the diving beetle genus Laccophilus Leach (Laccophilus obliquatus Régimbart, L. paraguensis Régimbart and L. testudo Régimbart) are described and illustrated for the first time, with an emphasis on morphometry and chaetotaxy of the cephalic capsule, head appendages, legs, last abdominal segment and urogomphi. Larvae of these species lack the primary setae LA10 and LA12, and have the primary seta CO7 articulated proximally on all coxae, two apomorphies that define the subfamily Laccophilinae. They are also characterized by a frontoclypeus truncate proximally in the first instar, the presence of pectens on legs, and the presence of secondary setae on first urogomphomere. These character states are apomorphies that define the genus Laccophilus Leach. The absence of pore PAc and the presence of a dense group of secondary spiniform setae dorsally at the base of the siphon in instar III may also characterize this genus, as similar states are not found in other dytiscids. On the other hand, L. obliquatus, L. paraguensis and L. testudo differ from the other species of Laccophilus known in detail in the presence of an additional seta on the stipes and in the absence of pore ABc. Brief comments on the putative phylogenetic relationships of Laccophilinae and Laccophilus inferred from larval morphology, as well as on the characters potentially useful in studying relationships within the group are presented.
Deep-sea spider crabs of the family Epialtidae MacLeay, 1838, from Papua
New Guinea, with a redefinition of Tunepugettia Ng, Komai & Sato, 2017, and descriptions of two new genera (Crustacea: Decapoda: Brachyura: Majoidea)
Authors: LEE BEE YAN , DE FORGES BERTRAND RICHER , NG PETER K. L.
Published: June 2019

The deep-water epialtid spider crab (superfamily Majoidea) material collected from recent French expeditions to Papua New Guinea (BIOPAPUA 2010, PAPUA NIUGINI 2012, MADEEP 2014, and KAVIENG 2014) was studied. In addition to several new records for the country, five new species of Oxypleurodon Miers, 1885, Rochinia A. Milne-Edwards, 1875, and Tunepugettia Ng, Komai & Sato, 2017, are described. The taxonomy of Tunepugettia is reappraised, and a new genus, Crocydocinus n. gen., is established, characterised by its smooth ambulatory legs and a distinct male first gonopod structure. Four species from the Bay of Bengal, Sumatra, and Réunion Island, currently placed in Rochinia and Tunepugettia are transferred to Crocydocinus n. gen. and four new species from Papua New Guinea, Philippines, and Vanuatu are described. A new genus, Neophrys n. gen., with one new species from Papua New Guinea, is established, and is characterised by the supraorbital eave being fused with the carapace and the poorly developed pre-orbital angle.
