Anthicidae (Coleoptera) of Madagascar: The Faunal Composition, New Descriptions, Rediscoveries, and an Annotated Checklist

A complete, annotated checklist of the ant-like flower beetles (Coleoptera: Anthicidae) recorded in Madagascar is provided for the first time. The list comprises 117 species and subspecies. The following seven species new to science are described and illustrated: Macratria durrelli sp. nov., Nitorus antankarana sp. nov., N. caviculus sp. nov., N. ciliatus sp. nov., N. saxatilis sp. nov., N. tsingy sp. nov., and Telesinus discolor sp. nov. Two new combinations are made: Nitorus caligans (Bonadona, 1958) comb. nov. and N. maculatus (Bonadona, 1958) comb. nov. (both from Pseudoleptaleus Pic, 1900). Original combination is restored for Leptaleus brevior Fairmaire, 1897. The following three new synonyms are introduced based on the examined type material: Anthicus atricornis Pic, 1913 = A. rudebecki Bonadona in van Hille, 1961 syn. nov. = A. meruanus Buck, 1965 syn. nov.; Macratria testaceilabris Pic, 1940 = M. testaceilabris var. sikorai Pic, 1940 syn. nov. Nineteen species are rediscovered after a long period of absent records. Colour images are provided for the first time for adults of several Madagascan taxa. New faunistic records of 52 taxa and results of a brief biogeographic assessment are presented. The calculated endemism rate in the Madagascan Anthicidae species and subspecies ranks taxa exceeds 80%, in genus rank taxa – 8%.
