Systematic review of the firefly genus Amydetes Illiger, 1807 (Coleoptera: Lampyridae), with description of 13 new species

A systematic review of Amydetes Illiger, 1807, based on examination of the type-material. We fix A. fastigiata Illiger, 1807 as the type-species of the genus; redescribe the genus and six out of eight species; describe 13 new species; and provide illustrations and a key to species. We place A. vigorsi Westwood, 1830 syn. n. and A. gorhami Kuntzen, 1912 syn. n. in synonymy with A. fastigiata; A. suturalis Pic, 1925 syn. n. and A. brasiliensis Pic, 1925 in synonymy with A. apicalis; and A. flavicollis Olivier, 1888 syn. n. in synonymy with A. lucioloides Olivier, 1888. We report the first record of Amydetes from Venezuela and Argentina, and establish more precise distributions of the studied species. We describe the circadian period of A. apicalis (diurnal), A. fastigiata and Amydetes bellorum sp. nov. (nocturnal) and discuss the circadian diversity of the genus. Fronto-clypeus, antenna, labrum, maxillary palpomere, prothorax, mesosternum, lanterns, abdominal segment VIII and terminalia were structures that provided important characters for delimitation and diagnosis of the species.

Ybytyramoan, a new genus of fireflies (Coleoptera: Lampyridae, Lampyrinae, Photinini) endemic to the Brazilian Atlantic Rainforest, with description of three new species

Here we describe a new Photinina genus with three species endemic to Serra dos Órgãos Mountains in Brazil. Ybytyramoan gen. nov. occurs in high altitudes, from 980m up to 2000m, and has the following unique set of characters: head abruptly depressed at vertex; lanterns not fully developed, somewhat rounded or anteriorly rounded, straight posteriad, with posterolateral rounded projections (billycock-shaped), at the middle of the abdominal sterna VI and VII; abdominal sternum VIII not covered by VII; phallus and parameres apically teethed. We provide illustrations and a key to the three species in this genus: Ybytyramoan praeclarum sp. nov. (type-species), Y. diasi sp. nov., Y. monteirorum sp. nov.

Inventário das espécies de Cerambycidae (Coleoptera) de Vila Dois Rios (Ilha Grande, Angra dos Reis, Rio de Janeiro, Brasil)

A survey of the Cerambycidae species recorded in Vila Dois Rios (Ilha Grande, Angra dos Reis, Rio de Janeiro, Brazil) is presented. The work was based on seven collects from January to December 2008, literature data and material housed in the Museu Nacional, Universidade Federal do Rio de Janeiro. Three subfamilies are recognized and all the 50 species are new records for Ilha Grande. Catalographic information, distribution, illustration and examined material are given. Prioninae with three species and three genera in two tribes, Mallaspini (Pyrodes) and Macrotomini (Mallodon, Mercosarthron), it represents 6% of all species. Cerambycinae with seven species and seven genera in five tribes - Callichromatini (Callichroma), Cerambycini (Poeciloxestia, Sphallotrichus), Elaphidiini (Ambonus, Eurysthea), Heteropsini (Mallosoma), Hexoplonini (Gnomidolon)- it represents 14%. Lamiinae, with 40 species in 29 genera and ten tribes - Acanthocinini (Alcidion, Lophopoeum, Nealcidion, Nyssodrysina, Nyssodrysilla, Nyssodrysternum, Pentheochaetes, Trichillurges, Tropidozineus, Urgleptes), Acanthoderini (Macronemus, Oreodera, Psapharochrus) Agapanthiini (Hippopsis, Pachypeza), Anisocerini (Onychocerus), Apomecynini (Adetus, Amphicnaeia, Falsischnolea, Rosalba), Colobotheini (Colobothea), Desmiphorini (Estola, Estolomimus), Hemilophini (Malacoscylus), Onciderini (Hesycha, Hypsioma, Ischiocentra, Peritrox) and Pteropliini (Esthlogena) - it represents about 80% of the total species.

Review of the Genus HAENKEA Tippmann (Coleoptera, Cerambycidae, Cerambycinae, Cleomenini)1

Abstract The genus Haenkea Tippmann and its three species, H. zischkai Tippmann (type species), H. thoracica (Chevrolat), and H. atra (Chevrolat), new combination, are revised. All the taxa are redescribed and illustrated. New data on geographical distribution and a key for species are also provided.

Dimorphism and allometry of Systaltocerus platyrhinus and Hypselotropis prasinata (Coleoptera: Anthribidae)

Males of sexually dimorphic anthribid species display structural modifications that suggest sexual selection. Polyphenism, which is expressed through morphological and behavioral novelties, is an important component of the evolutionary process of these beetles. In this study, we endeavored to ascertain the presence of variations in selected monomorphic traits, polyphenism in males, and variation in structures associated with sexual dimorphism and allometric patterns in two species: Systaltocerus platyrhynus Labram & Imhoff, 1840 and Hypselotropis prasinata (Fahraeus, 1839). To that end, we used Principal Components Analysis (PCA) and Canonical Variate analysis (CVA) to statistically analyze 26 measurements of 91 specimens. The PCA discriminated three groups (females, major, and minor males) for S. platyrhinus, but only two groups (males and females) for H. prasinata. The same groups discriminated by the PCA for Systaltocerus were confirmed by the CVA analysis, indicating a highly significant variation separating the three groups. We also analyzed positive allometry with respect to prothorax length - independent variable by Reduced Major Axis (RMA). The allometric pattern indicated by most of the linear measurements was strong and corroborates a possible relationship between male polyphenism and the reproductive behavior of major and minor males. We believe that these patterns, in species that show both sexual dimorphism and male polyphenism, are associated with the behavior of defending the female during oviposition, performed by major males.

Revision of the Genus LISTROPTERA Audinet-Serville and Description of AGUASSAY, New Genus (Coleoptera, Cerambycidae, Cleomenini)1

Abstract The genus Listroptera Audinet-Serville (type species Callidium tenebrosum Fabricius) is revised and the following species redescribed: L. tenebricosa (Olivier) and L. carbonaria Chevrolat. Aguassay, new genus, is described based on Cerambyx collaris Klug, up to now belonging to Listroptera. Aguassay collaris (Klug), new combination, is redescribed and its geographical distribution widened. A key to recognize the neotropical genera Dihammaphora Chevrolat, Haenkea Tippmann, Listroptera Audinet-Serville and Aguassay, all of which form a homogeneous group within the tribe Cleomenini, is also included.

Integrative taxonomy of new firefly taxa from the Atlantic Rainforest

Tropical mountains are hotspots of biodiversity, hosting many endemic species. Here, we propose Luciuranus gen. nov. and four new firefly species dwelling in montane habitats of the Brazilian Atlantic Rainforest. Luciuranus gen. nov. is unique in the shape of the last abdominal segments of both males and females, varying in a clear species-specific fashion. Luciuranus josephi sp. nov. and L. jameshooki sp. nov. are restricted to Serra dos Órgãos mountain range, while L. dextrus sp. nov. and L. sinistrus sp. nov. are restricted to Serra da Mantiqueira formation. DNA barcoding with COI gene confirmed species identities and male–female associations. We propose that terminalia structures work together as a lock-and-key mechanism, avoiding hybridization in overlapping zones along heterogeneous habitats, such as montane forests, where temperature, moisture, and vegetation cover can change significantly even in small spatial and temporal scales. Such morphological displacement is discussed in terms of sexual selection on both male and female features. We also provide detailed morphological descriptions, illustrations, and a key to species based on males and females. http://zoobank.org/urn:lsid:zoobank.org:pub:05598351-4655-49E5-9011-B90DFC7D9435

Description of the immature stages of Pentacomia (Mesochila) smaragdula Dejean 1825) (Coleoptera: Carabidae, Cicindelinae), with notes on the species distribution.

The Atlantic Rainforest is one of the most threatened biomes of the world, with only 11-12 % of its original cover. The Cicindelinae are present in this biome with a relatively high diversity, but data of their immature forms are few. On the basis of six larvae and four pupae of Pentacomia (Mesochila) smaragdula we describe and illustrate the third larval instar of the larva and the pupa of this species. Notes on the species distribution are also given.
