Revision of the endemic Madagascan stag beetle genus Ganelius Benesh, and description of a new, related genus (Coleoptera: Lucanidae: Lucaninae: Figulini)

  • This paper revises the genus Ganelius Benesh, which is endemic to Madagascar, in the stag beetle tribe Figulini Burmeister (Coleoptera: Lucanidae: Lucaninae). Species in the genus are striking in their highly sexually dimorphic mandibles, a character that rarely occurs in the tribe. The genus was previously comprised of four species, but three of these names were problematic or questionably applied. A lectotype is designated for G. madagascariensis Laporte, a neotype is designated for Ganelius oberndorferi Nonfried, and Nigidius passaliformis Benesh is newly synonymized with G. oberndorferi. Two new species, G. gnamptus Paulsen and G. zombi Paulsen, are described from western Madagascar. The identity of the overlooked Ganelius nageli (Kriesche) is fixed through a neotype designation, and the species is moved to the new genus Agnelius, which is distinguished from Ganelius by a lack of sexual dimorphism, serrate protibiae, and a more flattened body.
