The genus is characterized by the aedeagus with long median lobe and by the bifid claws in male and simple in female. Although the descriptions of the species are comprehensive, they are not complete, for instance there are no descriptions of the female genitalia or morphological structures such as tegmen and metendosternite. There is also no study about the position of Erynephala in the Section Schematizites, neither of the degree of affinity among the species. The objectives of this study are (1) to review Erynephala, providing detailed descriptions and illustrations of the internal and external morphology of males and females; (2) to distinguish the species through linear and geometric morphometrics; (3) to perform a cladistic analysis to test the monophyly of the genus and propose hypothesis of relationships among the species of Erynephala. The geometric morphometrics was more efficient to distinguish E. interrupta, E. puncticollis and E. morosa; on the other hand, the linear morphometrics clarified the species that were not delimited with the morphological characters. These two techniques allied to the study of the morphology enabled to distinguish E. maritima from de E. puncticollis var. texana (junior synonym of E. maritima), revalidating Erynephala texana (Schaeffer, 1932), stat. nov. All the analysis revealed that there are no differences between E. maritima and E. brighti, suggesting that this second species should be considered junior synonym of E. maritima. The cladistic analysis performed under implied weighting recovered the monophyly of Erynephala and reveled that the species form three clades: (((E. brighti + E. maritima) + E. texana) + (E. morosa + E. puncticollis) + E. interrupta). Monoxia (?angularis? group) was recovered as sister group of Erynephala, but Ophraella was not, genera that, as Monoxia, was considered related of Erynephala in some preview contributions. These results bring a new configuration to the species o Erynephala, however it is suggested a molecular analyses to corroborate the synonyms and to estimate the divergence time among the species.Erynephala Blake, 1970, integrante da se??o Schematizites (Coleoptera, Chrysomelidae, Galerucinae, Galerucini) compreende seis esp?cies, cinco com distribui??o Ne?rtica: E. brighti Blake, 1970, E. glabra Blake, 1936, E. maritima (LeConte, 1865), E. morosa (LeConte, 1857) e E. puncticollis (Say, 1824); e uma com distribui??o Neotropical, E. interrupta (Jacoby, 1904). As principais caracter?sticas diagn?sticas do g?nero s?o o aedegus com lobo m?dio alongado e as garras simples nas f?meas e b?fidas nos machos. Embora as descri??es das esp?cies sejam abrangentes, n?o s?o completas, por exemplo, faltam descri??es da genit?lia feminina e de estruturas morfol?gicas como o t?gmen e metendosternito. Tamb?m n?o h? estudos sobre a posi??o de Erynephala dentro da se??o Schematizites nem do grau de parentesco entre as esp?cies. Esse trabalho objetiva (1) revisar Erynephala, fornecendo descri??es e ilustra??es detalhadas da morfologia interna e externa de machos e f?meas; (2) buscar diferenciar as esp?cies atrav?s da morfometria linear e geom?trica; (3) conduzir uma an?lise clad?stica para verificar a monofilia do g?nero e propor hip?teses de parentesco entre as esp?cies de Erynephala. A morfometria geom?trica se mostrou mais eficiente em dintinguir E. interrupta, E. puncticollis e E. morosa; por outro lado, a morfometria linear esclareceu as esp?cies que n?o foram delimitadas com os caracteres morfol?gicos. A utiliza??o dessas duas an?lises morfom?tricas aliadas ao estudo da morfologia possibilitou distinguir E. maritima de E. puncticollis var. texana (considerada sin?nimo j?nior de E. maritima), revalidando Erynephala texana (Schaeffer, 1932), stat. nov. Todas as an?lises mostraram que n?o h? diferen?as entre E. maritima e E. brighti, sugerindo que esta segunda esp?cie seja considerada sin?nimo j?nior de E. maritima. A an?lise clad?stica conduzida com pesagem impl?cita suportou a monofilia de Erynephala e revelou que as esp?cies se dividem em tr?s clados: (((E. brighti + E. maritima) + E. texana) + (E. morosa + E. puncticollis) + E. interrupta). Erynephala ? recuperado como grupo irm?o Monoxia do grupo ?angularis?, mas n?o se mostrou relacionada a Ophraella, g?nero que, assim como Monoxia, foi considerado pr?ximo a Erynephala em contribui??es anteriores. Estes resultados trazem uma nova configura??o para as esp?cies de Erynephala, entretanto ? sugerido uma an?lise molecular para corroborar as sinon?mias e estimar o tempo de diverg?ncia entre as esp?cies

Contributions to the taxonomy of Neotropical Cyparium Erichson (Coleoptera: Staphylinidae: Scaphidiinae), with the description of five new species

The genus Cyparium Erichson, 1845 (Staphylinidae, Scaphidiinae, Cypariini) comprises 55 species, distributed mainly in the Neotropical and Oriental regions. Twenty-four species are known from the Neotropical region, but only eight species are reported from Brazil. In this paper we describe five new species and redescribe two species of Brazilian Cyparium, as follows: Cyparium achardi sp. nov., C. lescheni sp. nov., C. loebli sp. nov., C. newtoni sp. nov., C. pici sp. nov.; Cyparium collare Pic, 1920; and Cyparium oberthueri Pic, 1956. We provide images of adult males and females and their dissected parts, and information on host fungi whenever available. We also provide a comparative plate of dorsal colour patterns of Neotropical Cyparium

Comparative morphology of two species of Caraguata Bechyné (Coleoptera, Chrysomelidae, Galerucinae, Galerucini)

ABSTRACT Caraguata Bechyné, 1954 (Galerucini, Galerucina) includes 38 species exclusively Neotropical, among them two sympatric species, C. atricornis (Clark, 1865) and C. guaporensis Bechyné, 1958. Given the lack of morphological studies in this group, we aimed to characterize the adult morphology of two species, providing descriptions, illustrations and comparisons of structures of the head, thorax, abdomen and genitalia. The external morphology includes the description of head, thorax, abdomen and its appendices; the internal morphology comprises endosternites, and male and female genitalia. Some similarities were observed, such as pubescence, mouth parts, apparent sexual dimorphism on ventrite V, spermatheca and vaginal palpi. The main differences are in (1) the body and antenna shape, (2) the antenna color pattern, (3) the depression of the pronotum, (4) the presence/absence of the tibial spur, (5) the form of the median lobe, (6) the tegmen and (7) the sternite VIII of the females. The morphological study of these species contributes to the knowledge of Galerucina, presenting important specific characteristics not employed until now. Thus, it can be a contribution for studies of comparative morphology, systematics and evolution of the group
