Material examined. Holotype. Male. BURUNDI: Bujumbura, 850 m, espace vert, 17.X.2006, pitfall traps, B. Nzigidahera ( MRAC 227560 View Materials ).

Paratypes. 1♂: 17.X.2006 remainder as for holotype ( MRAC 227562 View Materials ) ; 1♂: 17.X.2006, remainder as for holotype ( MRAC 227561 View Materials ) ; 1♂: 17.X.2006, remainder as for holotype ( INECN) .

Diagnosis. The male of this species is recognized by the palpal tibia having four modified spines, directed forwards and by the thick embolus with a slender, curved tip. It shares the highly diagnostic presence of modified retrolateral spines on the tibia with Cydrela neptuna sp. nov., but in that species there are only three spines. In the present species the embolus is much shorter than in C. neptuna .

Etymology. The specific name, a noun apposition, is from the Greek “ ΚρƐαγρα ” (fork) and refers to the four spines on the male palpal tibia.

Description. Male (holotype). Total length 8.80, carapace 4.00 long and 2.60 wide. Carapace, reddish brown, with darker striae radiating from fovea; elevated in cephalic area and steeply sloping towards posterior margin. Eyes, area between eye group and fovea with long and white hairs. AME: 0.08; ALE: 0.13; PME: 0.11; PLE: 0.08; AME-AME: 0.08; AME-ALE: 0.07; PME–PME: 0.08; PME-PLE: 0.02; MOQ: AW = 0.78 PW: AW = 0.72 L. Chelicerae reddish brown, with dense cover of dark hairs. Sternum brownish orange; shield shaped with small frontal indentations; without precoxal sclerites. Labium colour as sternum. Leg coxae reddish brown dorsally, brownish orange ventrally; patellae and tibiae reddish brown, metatarsi and tarsi brownish orange. Abdomen, dorsum dark grey, with four pairs of pale spots and a single spot in front of spinnerets. Venter grey with, longitudinal whitish spots in four lines. Spinnerets bi-articulated, proximal part pale, distal part grey. Palp ( Figs 2 A, B View FIGURE 2 ): tibia with four long, flattened retrolateral spines directed forward; cymbium with four strong spines near distal margin and several smaller ones along prolateral margin; tegulum pear-shaped: distal part membranous, partly hidden by embolus; embolus inserted subdistally on narrowed part of tegulum short, proximal part thick, tip, distal part tapered and curved.
