Figs 93–94
Diagnosis
The species is similar to Thyene ocellata (Thorell, 1899). The male of Thyene masindi sp. nov. can be recognized by the male palp that has a shorter embolus without a thorn at the base, and by the absence of a flap-like protrusion on the bulb (compare Fig. 94A with Wesołowska & Russell-Smith 2011: fig. 211). The female is easily distinguished by the colouration of the abdomen, with only one pair of light spots (two–three pairs in T. ocellata – compare Fig. 93E and Fig. 93G).
Etymology
The name of this species is a noun in apposition, derived from the Ugandan province, where the type specimen was recorded.
