Contribution to the knowledge of Aegidinus Arrow

 

Frolov A. V., Akhmetova L. A., Vaz-de-Mello F. Z. 2019. Contribution to the knowledge of Aegidinus Arrow (Coleoptera: Scarabaeidae: Orphninae): new species and comments on the classification and nomenclature. Journal of Natural History. 53 (11-12): 725-747.

Two new species of the Neotropical Orphninae genus Aegidinus Arrow are described: Aegidinus noriegai sp. nov. and Aegidinus colbyae sp. nov. The lectotype of Orphnus candezei Preudhomme de Borre, 1886, is designated. Aegidium steinheili Harold, 1880, considered a synonym of Aegidinus guianensis (Westwood, 1846) is revalidated as Aegidinus steinheili (Harold). The following new synonymies are established: Aegidinus oreibates Colby, 2009 = Aegidinus guianensis (Westwood, 1846), syn. nov.; Aegidinus crypticus Colby, 2009 = Aegidinus guianensis (Westwood, 1846), syn. nov.; Aegidinus sunidigea Colby, 2009 = Aegidinus candezei (Preudhomme de Borre, 1886), syn. nov.; Aegidinus unicus Colby, 2009 = Aegidinus cornutus Colby, 2009, syn. nov. The male of Aegidinus simulatus Colby, 2009, is described. An updated diagnostic key to the males of Aegidinus is provided. The taxonomic and diagnostic characters as well as phylogenetic relationships of Aegidinus are discussed.

Contribution to the knowledge of the Neotropical canopy dwelling genus Onorius

 

Frolov A. V., Akhmetova L. A., Vaz-de-Mello F. Z. 2019. Contribution to the knowledge of the Neotropical canopy dwelling genus Onorius (Coleoptera, Scarabaeidae, Orphninae): another species from southern Ecuador and notes on the hind gut morphology in the Orphninae. Journal of Natural History. 53 (17–18): 1071–1077.

The generic status of Neotropical Orphninae genus Onorius Frolov et Vaz-de-Mello is supported by the discovery of another species in south-eastern Ecuador. The new species differs from O. inexpectatus Frolov et Vaz-de-Mello in the body sculpture and colouration. Both species have two large diverticula in the proximal part of the ileum; such structures are not found in the other members of the Aegidiini and are supposedly autapomorphic for Onorius.

Revision of the mainland species of the Neotropical genus Aegidium Westwood

 

Frolov A. V., Akhmetova L. A., Vaz-de-Mello F. Z. 2017. Revision of the mainland species of the Neotropical genus Aegidium Westwood (Coleoptera: Scarabaeidae: Orphninae). Journal of Natural History. 51 (19–20): 1035–1090.

The Orphninae genus Aegidium Westwood is revised from mainland South and Central America. Ten new species are described: Aegidium angustum sp. nov., Aegidium bordoni sp. nov., Aegidium gilli sp. nov., Aegidium howdeni sp. nov., Aegidium onorei sp. nov., Aegidium peresfilhoi sp. nov., Aegidium peruanum sp. nov., Aegidium rafaeli sp. nov., Aegidium sinuatum sp. nov. and Aegidium varians sp. nov. The lectotype of Aegidium columbianum Westwood is designated. Keys, descriptions, illustrations of habitus and male genitalia, and distributional record maps are given for all species.
