Revision of the genus Aegidium Westwood, 1845, of the Lesser Antilles (Coleoptera: Scarabaeidae, Orphninae, Aegidiini). Aegidium parvulum Westwood, 1846, from Guadeloupe, A. vincentiae Arrow, 1903, from St Vincent and A. dominicense (Cartwright & Chalumeau, 1977) from Dominica are redescribed. A. chalumeaui n. sp. from Guadeloupe and A. dierkensi n. sp. from Martinique are described. The five species are illustrated. Two identification keys are provided, one for the neotropical genera and one for the Aegidium species of the Lesser Antilles.

A new genus and species of Orphninae associated with epiphytes in Andean cloud forest

Frolov, A.V., Vaz-De-Mello, F.Z. 2015. A new genus and species of Orphninae (Coleoptera: Scarabaeidae) associated with epiphytes in an Andean cloud forest in Ecuador. Zootaxa, 4007 (3): 433–436

Orphninae (Coleoptera: Scarabaeidae) are represented in the New World by the tribe Aegidiini, which is comprised of four genera (Paulian 1984). Examination of material collected in Ecuador revealed a series of the Aegidiini specimens from an undescribed species that cannot be classified as a member of one of the known genera. The new species is herein described and a new genus is established. Apart from the distinctive morphological characters, the new taxon shows an unusual, for the Orphninae, association with canopy epiphytes.

A new species of Aegidium Arrow from the Atlantic forest ecoregion

Frolov, A.V., Grossi, P.C., Vaz-De-Mello, F.Z. 2015. A new species of the genus Aegidium (Coleoptera, Scarabaeidae) from the Atlantic Forest ecoregion in South America. Zootaxa, 4007 (3), 437–439.

The New World genus Aegidium Arrow comprises mid-sized to rather large beetles belonging to 12 species. The genus is distributed up to southern Mexico in the north (Morón 1991) and A. cribratum chileanum Paulian was described from Chile, but Aegidium has not been recorded southeast of the Amazonia. An interesting discovery was made by one of us (P.C.G.) who collected one male Aegidium specimen in the Atlantic forest patch near Nova Friburgo (Rio de Janeiro State, Brazil) — the area separated from the yet known range of the genus by vast territories occupied by the Cerrado biome. Examination of this specimen showed that it belongs to an undescribed species and differs sharply from the other congeners in the shape of its aedeagus.
