TYPES: Male holotype: in residual forest, elev. 2200 m, 4 km south Mt Kabobo, Haute. Kiymbi, Katanga, Congo S05°07', E29°03' (October 1958; N. Leleup) ( MRAC 112.989 ). Paratypes: 36, 2♀ in humus layer, elev. 1700 m, Mt. Kabobo, same locality (October 1958; N. Leleup) ( MRAC; 16, 1♀ in AMNH) ; 1♀ in humus layer, elev. 1800 m, Mt. Kabobo , same locality (October 1958; N. Leleup) ( MRAC) .

ETYMOLOGY: The species is named in hon­ or of Dr. Narcisse Leleup, collector of all the specimens available.

DIAGNOSIS: Males of H. narcissus are recognized by the huge sickle­shaped MA and the smaller sickle­shaped RTA. Females are close to those of H. lejeunei and H. falcatus but differ from both species by the absence

MALE: Measurements.: Total length 2.70; carapace 1.19 long, 0.92 wide; length of fe: I 1.03, II 1.08, III 0.84, IV 1.22. Leg spination. Fe: I rv 2; IV plt 0 rlt 0; ti: I, II vsp 6; mt: III plt 1 vt 0 rlt 0; IV plt 1 vt 1 rlt 1. Coloration. Carapace yellow ochre, chelicerae yellow. Sternum lemon yellow. Legs yellow. Abdomen pale peach, no pattern. Palp. Tibia with large, sickle­shaped RTA having a sickle­shaped prong with upward curved tip and knob­shaped base, a second, narrow, almost straight prong pointing inward; cymbium with large, ill­defined retrolateral bend with series of long setae; sperm duct with wide basal part and not much narrower distal part with sharp turn just in front of embolus; MA large, curved down, sickleshaped, and with thin flap along dorsal median margin; embolus with fairly broad, triangular base, long, whiplike, looped over 450° (fig. 24d, e).

FEMALE: Measurements. Total length 3.24; carapace 1.54 long, 1.32 wide; length of fe: I 1.38, II 1.49, III 1.19, IV 1.57. Leg spination. Fe: I rv 2; IV plt 0 rlt 0; ti: I, II vsp 6; mt: III plt 0 vt 0 rlt 0; IV plt 1 vt 1 rlt 1. Coloration. Carapace orange yellow. Chelicerae and sternum yellow. Legs orange yellow. Abdomen peach, no pattern. Genitalia. Epigyne a transversal slit with central bulge (fig. 24f). Vulva: entrances of IDs separated by about half the width of entire vulva; ID consisting of wide and very thickwalled, looped first stretch associated with gland and connected to ST1 through long and tortuous duct consisting of several circular and horseshoe loops; ST1 separated by at least their own diameter (fig. 25a, b).

VARIABILITY: The shape of the sickleshaped RTA process and the exact course of the coils and loops of ID are somewhat variable.

DISTRIBUTION: Mt. Kabobo, Katanga, Congo between elev. of 1700 and 2200 m.
