Published: March 2020

Abstract
Cruciferous vegetables have been of special interest due to the rich presence of bioactive compounds such as sulforaphane which show promising potential on cancer prevention and therapy as an epigenetic dietary strategy. Abnormal epigenetic alteration as one of the primary contributors to tumor development is closely related to breast cancer initiation and progression. In the present study, we investigated the effect of dietary broccoli sprouts (BSp), a common cruciferous vegetable, on prevention of estrogen receptor (ER)-negative mammary tumors at three different temporal exposure windows using a spontaneous breast cancer mouse model. Our findings indicate that maternal BSp treatment exhibited profound inhibitory and preventive effects on mammary cancer formation in the nontreated mouse offspring. The BSp diet administered to adult mice also showed suppressive effects on mammary cancer but was not as profound as the maternal BSp preventive effects. Moreover, such protective effects were linked with differentially expressed tumor- and epigenetic-related genes, as well as altered global histone acetylation, DNA methylation, and DNA hydroxymethylation levels. We also found that the expression changes of tumor-related genes were associated with the levels of histone methylation of H3K4 and H3K9 in the gene promoter regions. In addition, BSp-enriched sulforaphane was shown to increase protein expression of tumor suppressor genes such as p16 and p53 and inhibit the protein levels of Bmi1, DNA methyltransferases, and histone deacetylases in ERα-negative breast cancer cell lines. Collectively, these results suggest that maternal exposure to key phytochemicals may contribute to ER-negative mammary tumor prevention in their offspring through epigenetic regulations.
A new species of the genus Canthon Hoffmannsegg (Coleoptera, Scarabaeidae, Scarabaeinae, Deltochilini) from central Brazil
Authors: Vaz-de-Mello Fernando Z. , Nunes Luis Gabriel De Oliveira Albuquerque , Costa-Silva Vinícius Da 
Published: March 2020

A new species of Canthon is described, illustrated and the morphological similarities with related species are discussed. The species Canthon cleidecostae was named after Dr. Cleide Costa a great beetles specialist. The subgeneric category of species is considered incertae sedis until the taxonomic revision of the genus Canthon is fully addressed. Also, we provide a key for genera, subgenera and isolated species-groups that can be confused with the genus Canthon.
A new genus of Phengodidae (Coleoptera) from the Neotropical Region
Authors: Vega-Badillo Viridiana , Zaragoza-Caballero Santiago , Ivie Michael A. 
Published: March 2020

Cleicosta, a new genus of Phengodidae containing two new species, C. equatoreana sp. nov., and C. monaguense sp. nov., are described. Additionally, a new combination for Cenophengus breviplumatus Wittmer, 1976 is included. Cleicosta gen. nov., is the thirty-eighth genus assigned to the beetle family Phengodidae in the new world and is also the most morphologically similar to Cenophengus LeConte, 1881. Both genera exhibit clearly separated tentorial pits, vertical frons and simple tarsomeres. In Cleicosta gen. nov., however, the antennal rami are 1.5 times longer than the corresponding antennomere, the pronotum is subquadrate and the elytra are short, reaching the first or second abdominal segment. In addition, it presents an aedeagus with lateral lobes slender, parallel exteriorly, narrowed medially to toothless apex.
Review of the genus Hovorestenia Santos-Silva (Coleoptera: Disteniidae)
Authors: Botero Juan Pablo 
Published: March 2020

Hovorestenia Santos-Silva, 2007 is a disteniid genus differentiated from other Neotropical Disteniini by the metatarsomeres II and V subequal in length, in contrast with the metatarsomere V distinctly longer than II in the other genera. So far, the genus is known only from male specimens. The discovery of new Hovorestenia species, represented by both sexes, shows that such current diagnostic character is sexually dimorphic, with metatarsomere V distinctly longer than II in female. The genus Hovorestenia is therefore reviewed and redescribed and two new species are described: H. cleideae, from Colombia and Ecuador, and H. espilota, from Colombia. It allowed to describe the hitherto unknown females and to appoint out sexually dimorphic characters for the first time in the genus. The genus is now composed of four species distributed from the central region of Colombia to Ecuador. Photographs of Hovorestenia species are included and a key to differentiate them is provided.
Description of the larva and pupa of Apion brevicorne Gerstaecker, 1854 (Coleoptera: Brentidae: Apioninae) with biological information
Authors: Lima Rosana Maria De , Santos Sandreli Berenice De Oliveira , Vaz Stephanie , Gomes Ana Laura Soares , Sousa Wesley Oliveira de 
Published: March 2020

Apion brevicorne Gerstaecker, 1854 (Coleoptera: Brentidae: Apioninae) is an ecologically and economically important weevil that feeds on seeds and tissues of trees in the genus Copaifera L. (Fabaceae). Although the genus Apion comprises 16 species restricted to the Paleartic region, the Neotropical species A. brevicorne is still considered as incertae sedis due to the absence of a systematic study about it. The first descriptions and illustrations of Apion brevicorne are provided here. Diagnostic characters of larva and pupa are included and compared with 13 species from other biogeographic regions. Details of immature Apioninae species associated with host plants from the Neotropical region are described for the first time.

Description of the late- or last-instar larva of Ischyomius Chevrolat, with comments on the family placement of the genus (Coleoptera: Tenebrionoidea: Pythidae)
Authors: Pollock Darren A. , McClarin Jim 
Published: March 2020

Study of recently collected larvae of two species of Ischyomius Chevrolat, 1871 from Napo and Pichincha, Ecuador, tentatively identified as I. denticollis Champion, 1916 and I. singularis Chevrolat, 1871 confirm the classification of the genus Ischyomius within the family Pythidae. Salient larval characters which solidify this placement are: 5 stemmata arranged into an anterior column of 3 and posterior column of 2, parabasal ridges along anterior margins of abdominal tergites, prominent urogomphi with inner urogomphal teeth and various dorsal tubercles, and transverse row of dentiform asperities along anterior margin of sternite 9. Important features of the larva are illustrated with photographs. A key to larvae of world genera of Pythidae is provided as well as natural history information on Ischyomius.

Authors: Sousa Rafael Clayton De Jesus e , Fuhrmann Juares 
Published: March 2020

Studies about the immature stages of Orphninae (Coleoptera: Scarabaeidae) species are scarce. The subfamily includes 214 species, but only 5 have the immature stages described: Chaetonyx robustus liguricus Mariani, 1946, Hybalus benoiti Tournier, 1864, H. rotroui Petrovitz, 1964 and Triodontus nitidulus (Guérin, 1844) from Old World; and Aegidium cribratum Bates, 1887 from the New World. The Neotropical genus Paraegidium Vulcano, Pereira & Martinez, 1966 encompass five species, mainly recorded from Brazil. Herein, the immature stages of P. costalimai Vulcano, Pereira & Martinez, 1966 are described and illustrated, along with remarks on the presence of egg-buster in Scarabaeidae first-instar larvae. A key to the third-instar larvae of known Orphninae and a comparative study of chaetotaxy are also provided.
New species and morphological notes on the termitophilous genera Fonsechellus Silvestri and Oecidiophilus Silvestri from Brazil (Staphylinidae, Aleocharinae, Corotocini, Termitoceina)
Authors: Zilberman Bruno , Fontes Luiz Roberto 
Published: March 2020

Fonsechellus Silvestri and Oecidiophilus Silvestri consist of two Neotropical genera of termitophilous rove beetles, which have been poorly characterized due to the scarcity of material for studies. Herein, based on material collected in the seventies and housed in the Museu de Zoologia da Universidade de São Paulo, two new species associated with Atlantitermes guarinim Fontes and Diversitermes sp., are described and illustrated: Fonsechellus heterosetosus sp. nov. and Oecidiophilus cleidecostae sp. nov., respectively. The latter represents the first record of the genus to Brazil. Also, Fonsechellus fragilis and F. fontesi are redescribed, and a key for species identification is provided for the genus. The condition of the membranous wings of Fonsechellus is addressed and discussed, and the definition of both genera is expanded.

Morphology and life cycle of a new species of Psilocladus Blanchard, 1846 (Coleoptera, Lampyridae, Psilocladinae), the first known bromeliad-inhabiting firefly
Authors: Vaz Stephanie , Da Silveira Luiz Felipe Lima , Rosa Simone Policena 
Published: March 2020

Fireflies (Coleoptera: Lampyridae) are soft-bodied beetles usually associated with mesic and hydric habitats. As such, terrestrial firefly larvae are commonly found in marshy environments and stream banks, while aquatic larvae might dwell in ponds, streams, mangroves, and even brackish water. Larval biology is especially important in fireflies, as the majority of species are extremely semelparous – that is, adults rely on resources gathered during larval stages. Despite their crucial relevance in firefly biology, larvae of only near 1% firefly species have been studied, and the majority of species remain known only from adult stages. That is especially true in the Neotropical region, where they are most diverse. Here, we describe Psilocladus costae sp. nov. after the study of adults and immature stages, the latter reported for the first time for the monotypic subfamily Psilocladinae McDermott, 1964. Interestingly, adults were first obtained by rearing the larvae, the former usually fly fairly high (ca. 10 m) and are therefore seldom collected at ground level by conventional methods (e.g., active search, Malaise traps). The new species is found in the Brazilian Atlantic Rainforest, inhabiting canopy bromeliads, an unprecedented habit for fireflies.
Morphology and biological notes of Macrosiagon octomaculata (Gerstaecker) triungulinid and a summary of the knowledge on immature stages of the genus (Ripiphoridae)
Authors: Ulysséa Mônica Antunes , Albertoni Fabiano Fabian 
Published: March 2020

Species of Macrosiagon Hentz are known to be wasp and bee parasitoids. Here, we present information on Macrosiagon octomaculata (Gerstaecker, 1855), including eggs and triungulinids, found on Paepalanthus polyanthus (Bong.) Sano (Eriocaulaceae) blooming in restinga habitat on Santa Catarina Island, South Brazil. This is the first record of an Eriocaulaceae species playing an important role in the Macrosiagon bionomics and the first accurate record of Ripiphoridae for southern Brazil, Santa Catarina state. In the study area, P. polyanthus attracted an inordinate number of insect species and one Thynnidae wasp was captured with a triungulinid on its wing. Eggs and triungulinids were also found on one plant of P. polyanthus and associated with M. octomaculata. We provide descriptions of the female reproductive organs as well as the morphology of the triungulinid of M. octomaculata. A detailed examination of the triungulinid revealed novelties that complement information from previous publications regarding the Ripiphoridae. We also compare triungulinids of M. octomaculata with those of other species, and provide a table summarizing comparative characters. Finally, we provide a table with current information on the recorded host species and immatures of Macrosiagon.
Comparative morphology of the larvae of the palm weevils Dynamis borassi (Fabricius) and Rhynchophorus palmarum (Linnaeus) (Curculionidae: Dryophthorinae): Two major pests of peach palms in the Neotropics
Authors: Vásquez-Ordóñez Aymer Andrés , Löhr Bernhard Leo , Marvaldi Adriana Elena 
Published: March 2020

The morphology of the larvae of Dynamis borassi (Fabricius) and Rhynchophorus palmarum (Linnaeus) was compared, described and illustrated. A complete definition of subtribe Rhynchophorina at the larval stage was elaborated, based on mature and submature larvae, and characters of the first instar larvae are provided for the first time. Diagnostic characters to distinguish the larvae of D. borassi and R. palmarum are mainly from the epipharynx and maxillae, but the abdominal terminal plate also provides differential features that can aid in the identification. The characterization of both species at the larval stage is expected to be useful in the implementation of new control strategies in palm plantations in South America. For practical reasons, a comparative table is appended in Spanish to serve as a quick diagnostic guide for species identification.
First report of Austroporus doctus (Blackburn) from New Zealand and description of its larva (Coleoptera: Phalacridae)
Authors: Gimmel Matthew L. , Leschen Richard A. B. 
Published: March 2020

The Australian species Austroporus doctus (Blackburn) is reported from New Zealand for the first time. Adults are illustrated and diagnosed, and late-instar larvae are fully described and illustrated. In addition, a summary of prior larval descriptions of Phalacridae is provided. This represents the first description of the morphology and habitat of the larvae within the genus Austroporus Gimmel and the Olibroporus-group of genera. Austroporus doctus is native to eastern Australia, where adults are distinguished from similar species by characters of the male genitalia and by a suite of external morphological features. There are no native members of Phalacridae known from New Zealand, but A. doctus represents the second introduced and established species there. A key is given to differentiate adult and larval A. doctus from the other introduced New Zealand species, Phalacrus uniformis (Blackburn).
A new enigmatic species of broad-nosed weevil endemic to Brazil and its phylogenetic placement within the tribe Naupactini (Coleoptera: Curculionidae: Entiminae)
Authors: Del Río María Guadalupe , Lanteri Analía Alicia 
Published: March 2020

A new species of Naupactini (Curculionidae: Entiminae) endemic to Brazil, Espírito Santo and Minas Gerais states, is herein described. It resembles the monotypic genus Hadropus Schoenherr in its general appearance, particularly in the shape of the elytra, and the color of the vestiture, but the results of a cladistics analysis herein conducted suggest that it belongs to the genus Stenocyphus Marshall. This genus ranges in São Paulo, Rio de Janeiro and Espírito Santo, mainly in the Atlantic forest of Brazil, and includes three other species. Stenocyphus costae sp. nov., distinguishes from the remaining species of Stenocyphus by the green iridescent scaly vestiture, having long stiff setae on the two pairs of elytral tubercles; the more slender rostrum; the shorter antennae; the convex disc of the pronotum; and the shorter and broader elytra. This paper includes a cladogram of the Naupactini genera showing the phylogenetic position of the new species, its complete description, photographs of male and female habitus, line drawings of genitalia of both sexes, and a key of the Stenocyphus species.
Diochus cleidecostae, a new species from the Brazilian Amazon and a discussion of the sexual dimorphism on sternum VIII (Coleoptera: Staphylinidae: Staphylininae: Diochini)
Authors: Caron Edilson , Navarro Bruna V. , Cajaiba Reinaldo L. 
Published: March 2020

Diochus Erichson is a worldwide rove beetle genus with species found in forest floor litter. Three species of Diochus were recently collected in northern Brazil, one of them considered as new and herein described. Within Diochus nanus-group, D. cleidecostae sp. nov. differs from D. apicipennis Cameron, D. nanus Erichson and D. perplexus Cameron by the aedeagus with clearing trifurcate apex of parameres; and differs from D. parvulus Kraatz by the three apical long setae of parameres distributed on ventral and dorsal lobes. A previous key to the D. nanus-group is updated to include the new species. Here we also report for the first time D. santacatarinae Irmler and D. parvulus from Pará state, Brazil. Finally, a discussion about the sexual dimorphism on sternum VIII is also provided for the genus.
New species and nomenclatural notes in Lobobrachus Sharp (Coleoptera, Carabidae, Pterostichini)
Authors: Campaner Carlos , Will Kipling W. 
Published: March 2020

A new species of Lobobrachus Sharp, 1885, Lobobrachus cleidecostae sp. nov., from Piauí state, Brazil, is described and illustrated. The genus and Lobobrachus lacerdae Sharp, 1885, are redescribed and the identity of L. alternans Tschitschérine, 1901, is discussed. Based on study of all available specimens and published descriptions it appears that L. alternans cannot be diagnosed and is a synonym of L. lacerdae. However, the syntypes of L. alternans cannot be located, thereby making a final decision on synonymy impossible to substantiate fully. Photographs of the aedeagi of L. lacerdae, L. cleidecostae, and specimens that best correspond to L. alternans, including those putatively identified by Tschitschérine, are presented for the first time.

New keys are proposed in English and Spanish for the identification of the Peruvian species of the genus Plectonotum and the South American species of the genus Hyponotum Wittmer, together with macrophotographs of habitus, details of pronotum, male genitalia and a cartographic representation of their distribution.
A new suspected paedomorphic genus of net-winged beetles from the Atlantic Rainforest (Coleoptera, Elateroidea, Lycidae)
Authors: Ferreira Vinicius S. , Silveira Luiz Felipe Lima 
Published: March 2020

Lycidae are among the better studied groups in the superfamily Elateroidea, however despite the progress in the taxonomic understanding of the Neotropical fauna, much still remains unknown and undescribed in the region. The description of the new genus Xenolycus gen. nov., from Serra dos Órgãos, a subrange of the Serra do Mar mountain range, in the Atlantic Rainforest in Rio de Janeiro State, Brazil, contributes to the knowledge of the Neotropical Lycidae fauna. The new genus can be distinguished from all other known Calopterini and Neotropical Lycidae by the combination of a pronotum with a wide, deep and strongly visible longitudinal cell in the disc area, the filiform antennae, the dehiscent elytra with reticulation strongly reduced and bearing only two weakly developed elytral costae and the mouthparts partially reduced, with rudimentary, barely visible mandibles. The type species, Xenolycus costae sp. nov., is illustrated and diagnostic characters and a discussion on the tribal placement of the new genus are provided.
