Holotype: NRM 385 This is the type species of the genus Colopus. Diagnosis of the genus: Colopus was originally diagnosed by Peters (1869) on the basis of its granular subdigital scales and much reduced lamellae, and digital features have remained the crucial elements in subsequent diagnoses (FitzSimons 1943; Loveridge 1947; Haacke 1976b). We here re-diagnose Colopus on the basis of the following suite of characteristics: body small (adults < 65 mm SVL), slender, elongate; dorsal surface of skull smooth; digit I of manus and pes hyperphalangic, with or without phalangeal loss in digit IVof manus (phalangeal formulae - 3-3-4-5-3 or 3-3-4-4-3 manus and 3-3-4-5-4 pes), lacking paraphalanges and interdigital webbing, subdigital surface granular, except distally, where there are 2-3 narrow subdigital lamellae beneath digit IV; precloacal pores lacking; tail cylindrical in cross section; dorsal skin smooth, not fragile (from BAUER & LAMB 2005).
