COPTOCATUS Montandon, 1909 View in CoL
Diagnosis. – Form elongate-oval. ( Fig. 1 View Fig ) Abdominal and thoracic venter with fine pile of short, closely appressed hairs. Pronotum not markedly expanded posteriorly (except in C. stereos ), posterior width less than 2× width of head; anterolateral angles of pronotum simple, not forming ventrallydirected cup-shaped depressions at apices. Hemelytra of brachypterous forms short and truncate, apices rounded, not reaching to abdominal tergite VI. Parameres variable in shape, either deeply cleft medially and asymmetrically bidentate, or uniramous and tapering on distal half, sometimes with a fringe of long setae on outer margins.
Discussion. – The genus Coptocatus is confined to Borneo, and was proposed by Montandon (1909) to hold a single species, C. oblongulus , collected near Mt. Kinabalu. Five additional species have been described subsequently by Polhemus (1986), Nieser & Chen (1991) and Zettel (2002). Although clearly members of the tribe Cheirochelini based on synapomorphies of the head and ventral abdomen (see Polhemus, 1986, Figs. 7, 8 View Figs ), Coptocatus species are narrower and more elongate in comparison to those of Gestroiella or Cheirochela (compare Figs. 1 View Fig , 2 View Fig and 18 View Fig ). The key below, modified from Zettel (2002), will permit identification of the species described to date.
