Phintella nilotica sp. nov. urn:lsid:zoobank.org:act: EF03DDC1-026A-427F-AB91-36773A03C068 Fig. 61 Diagnosis The male of this species differs from congeners by the shape of the bulb, which has a separated posterior part and long anterior haematodocha, a posterior lobe is absent. The embolus in Phintella nilotica sp. nov. is longer than in other species of Phintella, slightly similar to that in Phintella caledoniensis Patoleta, 2009; however, the newly described species can be recognized by a longer bulb (twice as long as the embolus in Ph. nilotica vs equally long in the latter species). Etymology The name is derived from the Nile River, at which sources this species was found. Material examined Holotype UGANDA • ♂; source of Nile, Jinja; 0°25′ N, 33°12′ E; Aug. 1994; D. Penney leg.; NHM. Paratype UGANDA • 1 ♂; Entebbe; Jan. 1996; FSCA. Description Male General appearance as in Fig. 61A MEASUREMENTS. Cephalothorax length 2.4, width 1.9, height 1.1. Eye field length 1.1, anterior and posterior width 1.4. Abdomen length 2.7, width 1.7. CARAPACE. Oval, medium height, brown with darker eye field, some white hairs between eyes of first row. White hairs form median belt on thoracic part and streak along carapace edges. Anterior eyes surrounded by fawn scales from bottom. Mouthparts brown, only chewing margins of endites whitish. Chelicerae long, unidentati (Fig. 61B). Sternum yellow. ABDOMEN. Oval greyish beige with thin median white streak, same streaks along sides joining on frontal edge. Sparse long brown bristles on dorsum. Venter with wide black strip. Spinnerets yellow. LEGS. First pair generally dark brown, only proximal end of patella, medium of tibia and tarsus yellow. Other legs yellow. Leg hairs and spines brown. PALP. Yellow with blackish cymbium, white hairs on tip of tibia and base of cymbium. Palpal tibia with single thin apophysis (Fig. 61E, G). Shape of bulb irregular, embolus long, its base positioned near bulb tip, slightly closer to prolateral side (Fig. 61C, F). Female Unknown.
