Diagnosis

This species may be distinguished by the abdominal pattern. The posterior half of the abdomen is occupied by a large black area divided into three parts. A small round white spot is located in the center of this black area in both sexes ( Fig. 70A, D ). This white spot is reduced to dot in the male. The male palp has a soft flap oriented transverse to the prolateral edge of the bulb ( Fig. 70B ).

Description

For both species see Wesołowska & Russell-Smith (2000) sub Thyene semiargentea . General appearance of male as in Fig. 70A , female in Fig. 70D , palpal organ as in Fig. 70B–C .

Remarks

The species was first reported by Clark (1974), who drew a female from Simon’s collection (locality unknown). He mistakenly identified the spider as Paramodunda thyenioides Lessert, 1925 . However, the type of the latter species has a different colouration and palpal structure (see figs in Prószyński 1984: 168). Wesołowska & Russell-Smith (2000) provided a detailed description of both sexes of Thyene aperta based on extensive material from Tanzania but wrongly determined it as Thyene semiargentea (Simon, 1884) . Prószyński (1987) studied the type of Mithion semiargenteus and his drawings clearly showed a different pattern of the abdomen and the vertical position of the flap on the bulb (see figs in Prószyński 1987: 111). Only the redescription of the types of Thyene aperta by Wesołowska (2012a) allowed for its recognition.

Distribution

A species previously known from Zimbabwe and Tanzania .
