A contribution to the knowledge of New World Bruchinae (Coleoptera, Chrysomelidae): taxonomic revision of Ctenocolum Kingsolver & Whitehead, with description of five new species

Abstract

The aim of this contribution was to review the species of Ctenocolum which are mainly distributed in the Neotropical region. The larvae of this genus have a high degree of specificity with the tribe Millettieae feeding mainly on seeds of Lonchocarpus Kunth (Fabaceae, Papilionoideae) and until now we do not know other bruchine consuming seeds of this genus. Here 13 valid species were studied, five new, divided in two groups, as previosly proposed in literature, group podagricus with Ctenocolum aquilus Albuquerque & Ribeiro-Costa sp. nov., C. biolleyi Kingsolver & Whitehead, C. colburni Kingsolver & Whitehead, C. martiale Kingsolver & Whitehead, C. milelo Albuquerque & Ribeiro-Costa sp. nov., C. podagricus (Fabricius), C. punctinotatus Albuquerque & Ribeiro-Costa sp. nov., C. pygospilotos Albuquerque & Ribeiro-Costa sp. nov. and C. triangulatus Albuquerque & Ribeiro-Costa sp. nov.; group tuberculatum with C. acapulcensis Kingsolver & Whitehead, C. janzeni Kingsolver & Whitehead, C. salvini (Sharp) and C. tuberculatum (Motschulsky). A lectotype is designated for Bruchus salvini and Bruchus pictifemur. Moreover, descriptions, redescriptions, diagnoses, key, geographic distribution and host plant records are also included.

Assembleia de Alticini (Coleoptera, Chrysomelidae, Galerucinae) em fragmentos florestais no sudoeste do Paraná, Brasil

“…No Paraná, dois grandes inventários entomofaunísticos foram realizados na década de 1980 e final da década de 1990 -o Levantamento da Fauna Entomológica no Estado do Paraná (PROFAUPAR) (Marinoni & Dutra, 1991) e o Projeto Vila Velha (PROVIVE) , respectivamente. Tais projetos geraram grande quantidade de material e apresentaram muita informação sobre a fauna de Coleoptera, Chrysomelidae e também de Alticini do Paraná, tanto em estudos ecológicos das comunidades amostradas (Marinoni & Dutra, 1997;, 2006Ganho & Marinoni, 2005;Linzmeier et al, 2006;Linzmeier & Ribeiro-Costa, 2009) quanto em estudos taxonômicos nos quais muitas espécies foram descritas e vários novos registros para o estado e para o Brasil foram confirmados (Araújo-Siqueira & Almeida, 2006;Linzmeier & Konstantinov, 2009;Fernandes & Linzmeier, 2012;Albuquerque et al, 2014;Roza & Mermudes, 2017;Gonçalves & Leivas, 2017). No entanto, não existem estudos que abordem a fauna de Alticini da região sudoeste do Paraná.…”
