Material examined. Holotype. Male. Congo DR, Albert National Park , sector Ruwenzori, Kalonge locality, 26.I.1953, 2000 m, Vanschuytbroeck P. and Kekenbosch J. ( MRAC 223405 ).

Paratypes. CONGO DR: 1 ♁: Albert National Park , sector of Ruwenzori, alt. 2000 m, 26.I.1953, Vanschuytbroeck P. and Kekenbosch J. ( MRAC 224077 ) ; 1 ♀: Bikara sector of Lubero-Goma, XII.1976, 2100 m, Lejeune, M. ( MRAC 159842 ) .

Diagnosis. Males of Zelotibia lejeunei are recognized by the large, bifid tibial apophysis with one remarkably robust horn. Females have the copulatory openings of the epigyne far in front and to the side.

Etymology. The specific name lejeunei refers to the name of person who has collected the material of this species.

Description. Male holotype: Total length 4.80, Carapace 2.00 long and 1.56 wide. Carapace brownish orange with brown striae radiating from fovea. Fovea short. Eyes AME area dark; anterior eye row recurved, posterior row straight. AME: 0.08; ALE: 0.08; PME: 0.08; PLE: 0.08; AME-AME: 0.02; AME-ALE: 0.02; PME-PME: 0.05; PME-PLE: 0.02. Chelicerae brownish orange. Sternum pale brown, dark brown along margin. Labium pale brown. longer than broad. Chelicerae brown, setose. Abdomen Dorsum pale grey, with scutum, long bristles at anterior end; ventrally yellow grey. Spinnerets pale yellowish. Legs brownish orange. Metatarsi III and IV with ventral preening comb at tip. Palp ( Figs 14-16 )with bifid tibial apophysis, originating in posterior half of segment; external horn longer and more robust than internal one ( Fig. 15 ). DTA with strong base, slightly curved at tip; PTA very robust, tip parallel with DTA ( Fig. 16 ).

Female paratype ( Fig. 8 ): Total length 4.80, Carapace 2.00 long, 1.44 wide. Colour pattern similar to male. Chelicerae: with three teeth on both margins. Epigyne ( Figs 23 , 33 ) with roughly heart shaped scape anteriorly. Copulatory openings far in front and to the side. Copulatory ducts, broad, with large diverticulum pointing forward, running obliquely towards the globular spermathecae, entering these in front.

Distribution. Known from the Ruwenzori and the region of Lubero, Congo DR
