A phylogenetic study of the subtribe Dicrepidiina (Elateridae, Elaterinae, Ampedini)

Abstract

ABSTRACT. A phylogenetic study of the subtribe Dicrepidiina (Elateridae, Elaterinae, Ampedini). It is presented a cladistic analysis of the Dicrepidiina aiming to test the monophyletism of the subtribe and to establish the relationships among the genera. The subtribe is composed by 36 genera and all of them, except Asebis, Lamononia, Neopsephus, Semiotopsis and Spilomorphus were included in the analysis. Fifty two species, especially the type-species of each genus were studied: Achrestus flavocinctus (Physorhinina). Os resultados da análise filogenética demonstraram que Dicrepidiina, como definida anteriormente, não forma um grupo monofilético. Um gênero, representado por Ovipalpus pubescens, foi removido da subtribo. A subtribo está caracterizada pela presença de lamela no 2º e 3º tarsômeros de todas as pernas. Também está evidente que os gêneros Achrestus, Anoplischius, Dipropus e Propsephus não são monofiléticos. Devido à falta de informações sobre o grupo, todas as espécies estudadas são redescritas e ilustradas.

New species of Elateridae (Coleoptera) from Madre de Dios, Peru, with new taxonomic changes and distribution records

“…1" of Johnson and Chaboo (2015). Casari (2008Casari ( , 2013 showed that the genus-level classification within Dicrepidiina requires further study. This new species can be associated with Candèze's (1859) Section II, which is characterized by antennomere 3 being shorter and narrower than antennomere 4, and differs from Section congeners by its small size, antennomeres 2 and 3 each smaller than antennomere 4, and opaque and bicolored dorsal integument.…”

Phylogenetic analysis and taxonomic revision of Physodactylinae (Coleoptera, Elateridae)

“…Terminology follows Calder (1996) & Costa et al (2010), except for (followed works in parentheses): wing venation and apical sclerotizations (Kukalova-Peck & Lawrence, 2004;Muona, 1993), density of punctures (Douglas, 2003), pterotergites (Friedrich & Beutel, 2006) and mouthparts (Casari, 2008). The term "pedunculate anterior sac" is used here in the sense of Douglas (2011).…”

“…2U). The free margin of metacoxal plate (Casari, 2008) is the expanded part of metacoxal plate that overlaps part of the metatrochanter and metafemur (Fig. 12O).…”

“…All characters were treated as having equal weight. Specific references are given to some characters that have been employed in previous cladistic analysis (Calder et al, 1993;Lawrence et al, 2011;Casari, 2008).…”

A new species of Dicrepidius Eschscholtz from Brazil and new records for D. ramicornis (Palisot de Beauvois) (Coleoptera, Elateridae, Elaterinae)

“…nov. is recorded from Pará and Mato Grosso states (Brazil). D. ramicornis is widely distributed, with records from United States of America (Texas), Mexico (Chontales), Nicaragua, Antilles (Cuba, Guadelupe, Saint Domingue), Argentina (Chaco, Formosa) and Brazil (Palisot de Beauvois, 1805, Candèze, 1859, Chevrolat, 1867, Champion, 1894, Schenkling, 1925, Blackwelder, 1944, Bruch, 1911, Golbach, 1994, Casari, 2008. From Brazil it was recorded only from Minas Gerais, Rio de Janeiro, São Paulo and Santa Catarina states, but now it was studied material also from Amazonas, Pará, Rondônia, Mato Grosso, Mato Grosso do Sul, Ceará, Goiás, Bahia, Espírito Santo and Paraná.…”
