Description of Monoleptoides gen. nov. from the Afrotropical Region, including the revision of nine species (Coleoptera: Chrysomelidae: Galerucinae)

摘要

Due to their specific external and genitalic patterns, several species of Afrotropical Galerucines, most of them originally described inMonolepta Chevrolat, 1837 and Candezea Chapuis, 1879, are transferred to the new genus Monoleptoides. This group isphylogenetically well defined and comprises nine previously described species, some of them well known, abundant, and widely distributed in tropical Africa. Taxa newly combined with Monoleptoides and new synonymies include: Crioceris duplicata Sahlberg,1823 (=Monolepta pulchella Klug, 1835; =Monolepta fasciaticollis Laboissiere, 1940a, syn. nov.; = Monolepta quinquepunctata Laboissiere, 1940a, syn. nov.); Monolepta trivialis Gerstaecker, 1855 (= Candezea umbilicata Laboissiere, 1920, syn. nov.); Monolepta didyma Gerstaecker, 1871; Monolepta thomsoni Allard, 1888: Monolepta advena Weise, 1910 (= Monolepta keniensis Bryant, 1953; syn. nov.); Candezea centromaculata Jaco-by. 1900: Candezea horni Laboissiere, 1931; Candezea mertensi Laboissiere, 1940b; Candezea sulcata Laboissiere, 1940a (= Candezea sexplagiata Laboissiere 1940a; syn. nov.). Detailed descriptions for the generotype, Monoleptoides duplicata and redescriptions of all species, as well as an identification key are given. Collection data arerecorded in detail for the 1190 specimens studied, and summarized in distribution maps.
