TYPES: Male holotype: Lukwangule Plateau, elev. 2400–2600 m, Uluguru Mountains, Tanzania S7°10', E37°40' (2–22 July 1971; L. Berger, N. Leleup, J. Debecker) ( MRAC 141.109 ). Paratypes: 1♀ together with holotype ; 16 in litter, elev. 1600 m, Lupanga East , Tanzania (10 July 1981; M. Stoltze and N. Scharff) ( ZMUC) .

ETYMOLOGY: The name leno, Latin for seducer, is a noun in apposition and refers to the fact that both male specimens known have expanded palps.

DIAGNOSIS: Males of H. leno are recognized by the large lateral RTA ending in a divergent bifid tip. Females are closest to those of H. klumpkeae but can be distinguished from them by the inward­running stretch of the ID, which is continuously curved instead of angular.

MALE: Measurements. Total length 2.16; nation. Fe: I rv 2; IV plt 0 rlt 0; ti: I, II vsp 5; mt: III plt 1 vt 0 rlt 0; IV plt 1 vt 2 rlt 1. Coloration. Carapace yellow brown, lighter around the fovea. Chelicerae yellow brown, legs yellow. Sternum yellow, bordered with a thin orange brown line. Abdomen pale yellow, no pattern. Eyes. Anterior median eyes with a bluish hue. Palp. RTA a lateral extension with bifid extremity, superior tip sharp and slender, inferior one blunt; cymbium fairly elongate, with shallow retrolateral concavity in proximal half; sperm duct fairly broad over entire course, slightly narrowed toward embolus, with sharp turn before entering triangular tegular swelling at base of embolus; MA originating in frontal part of tegulum, curved over tegulum, gradually tapered toward tip, which reaches RTA; embolus originating from triangular extension on posterior part of tegulum, whiplike, fairly short, distal part appressed against MA (fig. 19e, f).

FEMALE: Measurements. Total length 2.67; carapace 1.08 long, 0.89 wide; length of fe: I 0.89, II 0.95, III 0.76, IV 1.00. Leg spination. Fe: I rv 2–3; IV plt 0 rlt 0; ti: I, II vsp 6–7; mt: III plt 1 vt 0 rlt 0; IV plt 1 vt 1 rlt 1. Coloration. Carapace orange brown, chelicerae orange yellow, and legs orange brown. Sternum lemon yellow, bordered with orange brown. Abdomen yellowish white, no pattern. Female genitalia. Vulva very simple, ID making sharp outward bend, followed by continuously curved inward­running stretch connected to ST1 (figs. 19g; 20f).

DISTRIBUTION: Tanzania, Uluguru Mountains, between elev. 1600 m and 2600 m.
