1.2.5. Curtonotum campsiphallum species-group

Species included: 7 (Afrotropical).

Synapomorphies: Lateral lobe with 1 very strong seta and group of shorter setae (35) and baso-ventral process of distiphallus developed into a short, blade-like, partially serrated process (39). Tsacas (1977) regarded the species C. angolense Tsacas , C. campsiphallum Tsacas , C. sao Tsacas and C. quinquevittatum Curran in his cuthbertsoni species-group, quinquevittatum complex. These four species, plus C. friedberg sp. n., C. hay sp. n. and C. tsacas sp. n. (described below), are here regarded as being sufficiently distinct to warrant inclusion in a species-group of their own, as attested by the above-mentioned synapomorphies.
