Description of a new genus and three new species of Metarbelidae (Lepidoptera: Cossoidea) from East and Central Africa, with notes on biogeography

摘要

Shimonia gen. nov., a new genus of Metarbelidae (Lepidoptera: Cossoidea), is described from East and Cen- tral Africa (Afrotropical Region). It currently comprises four species, three of which are described as new: S. timberla- kei sp. n., S. oyiekeae sp. n. and S. fischeri sp. n. The fourth species, S. splendida (Fletcher, 1968) is here transferred to the new genus from Metarbela Holland, 1893. Illustrations of adult morphology and notes on ecology and biogeography of these species are presented.
