Orexita Spaeth, 1911

Orexita Spaeth, 1911: 254 (original description).

Type species. Coptocycla complanata Boheman, 1855 , designated by HINCKS (1952).

Remarks. SPAETH (1911) established the genus Orexita for conspicuous group of species described in the genus Coptocycla Chevrolat, 1836 , and characterized by large and flattened body. Spaeth pointed that this group of species is however more related to Physonota than to other species classified as Coptocycla as they differ in flat prosternum, elongate tarsomere IV and short antennae in proportion to body length. However, he kept Orexita in the tribe Cassidini ( SPAETH 1914, 1942) and subsequent authors accepted this position ( HINCKS 1952, BOROWIEC 1999a). I concur with SPAETHʼs (1911) findings and hereby transfer Orexita from Cassidini to Ischyrosonychini . Ischyrosonychini differ in having a transverse head with small eyes, while Cassidini have circular head, mostly with large eyes.
