Lachnopus curvipes Fabricius 1787 and its radiation in the Caribbean region (Coleoptera: Curculionidae: Entiminae)

Lachnopus curvipes (Coleoptera: Curculionidae: Entiminae: Geonemini) is currently the most widespread Lachnopus species in the Caribbean region, ranging from Jamaica to Saint Vincent in the Lesser Antilles. It can be distinguished from its congeners by the characteristic metatibia of the males, which is curved and bears a prominent tooth on the proximal region of its ventral area. A morphological survey of specimens from 11 different islands in addition to eight different localities in Puerto Rico has lead to the distinction of at least 6 closely related morphotypes which, after a complete revision of the genus, should be recognized as separate species. Morphological evidence from external and internal characters will be presented.
