Treatment

Hyllus bisulcus sp. nov.

Fig. 16 View FIGURE 16

Diagnosis. The palpal organ of this species is very similar to that of the Oriental Hyllus diardi (Walckenaer, 1837) , but it has a tibial apophysis with a bifurcated tip, whereas H. diardi has an apophysis with single blunt tip (compare Fig. 16E View FIGURE 16 with Żabka 1985: fig. 223). Female unknown.

Etymology. The specific epithet is the Latin word meaning “forked” and refers to the shape of the tibial apophysis.

Type material. Holotype: 1♂, MOZAMBIQUE: Tete: IV.1947, leg. C.F. Roewer ( SMF 9905 About SMF ).

Paratypes: MOZAMBIQUE: Tete: no further details, 1♂ ( SMF 9702 About SMF ), 1♂ ( SMF 9685 About SMF ) .

Other material. TANZANIA: Usambara Mountains , no further details, 1♂ ( SMF) .

Description. Male: Measurements: Cephalothorax: length 6.3, width 5.1, height 4.1. Eye field: length 2.4, anterior and posterior width 3.1. Abdomen: length 6.1, width 3.4. General appearance in Fig. 16A View FIGURE 16 . Carapace rounded, reddish-brown, eyes encircled by black rings. Some long bristles on carapace. Clypeus and frontal surfaces of chelicerae with dense long colourless hairs. Sternum light brown, labium and endites darker with whitish tips. Abdomen elongate, narrower than carapace, reddish-brown, with sparse long bristles, denser at anterior edge. Venter light brown with two lines formed by white dots. Spinnerets brown, hairy. Legs dark brown, bearing very dense brown and colourless hairs, especially dense on legs I and II. Palps small, dark brown, with dense hairs. Tibial apophysis short, forked at the top ( Fig. 16C, E View FIGURE 16 ). Bulb oval, with small posterior lobe, embolus accompanied by pars pendula ( Fig. 16B, D View FIGURE 16 ).

Distribution. Northwestern Mozambique and northeastern Tanzania.

Remark. There are numerous African Hyllus C.L. Koch, 1846 that are only known from females that could potentially be a match to this species, but this can only be assessed once specimens are collected from the same locality.
