TYPES: Male holotype: in litter, elev. 1800 m, Mwanihana Forest Reserve , above Sanje, Uzungwa mountains, Tanzania (18 August, 1982; M. Stoltze and N. Scharff) ( ZMUC). Paratypes: 1♀ in pitfall trap, same collection data ( ZMUC) ; 16, 1♀ in pitfall trap in montane rain forest, elev. 1800–1850 m, same locality (25–29 September, 1984; N. Scharff) ( ZMUC) ; 1♀: in pitfall trap in montane rain forest, elev. 1850 m, same locality (29 September, 1984; N. Scharff) ( ZMUC) .

ETYMOLOGY: The species’ epithet refers to the biotope where the type specimens were found: saltus means montane forest.

DIAGNOSIS: Males of H. salticola are recognized by the thin, slender RTA, almost parallel with the proximal margin of the cymbium. Males are very similar to those of H. ostiovolutus (see under that species for difference). Females can be recognized by the epigyne consisting of two transversal slits, the simple ID curving inward, and the piriform ST1.

MALE: Measurements. Total length 1.89; carapace 0.95 long, 0.78 wide; length of fe: I 0.78, II 0.84, III 0.68, IV 0.95. 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 yellow, lighter around the fovea. Chelicerae, sternum, and legs pale yellow. Abdomen yellowish white, without pattern. Palp. RTA simple, fairly narrow at base and gradually tapered toward sharp tip, distal part almost parallel with axis of segment; cymbium fairly elongate, with shallow, narrow retrolateral concavity but without series of curved hairs; sperm duct fairly broad over entire course, restricted to anterior half of tegulum except for last loop, slightly narrowed just before entering embolus; MA tapered in basal part, slender and sharply curved down in distal part, tip reaches base of RTA; embolus originating on posterior half of prolateral part of tegulum, whiplike, fairly short, distal part appressed against MA (fig. 9j, k).

FEMALE: Measurements. Total length 2.70; carapace 1.22 long, 1.05 wide; length of fe: I 1.00, II 1.08, III 0.86, IV 1.22. Leg spination. Fe: I rv 2; IV plt 0 rlt 0; ti: I, II vsp 7; mt: III plt 0 vt 0 rlt 0; IV plt 1 vt 1 rlt 1. Coloration. Carapace yellow ochre. Chelicerae and legs I and II yellow ochre, legs III and IV yellow. Sternum yellow. Abdomen pinkish yellow, without pattern. Genitalia. Epigyne two long, transversal slits situated at anterior end of ST1 (fig. 9l). Vulva: ID entrances widely separated; ID itself simple, curved inward over 90°, running in posterior direction; entrance associated with glandular structure connected with the lumen through a series of pores. Spermathecae 1 large, piriform (fig. 11e).

DISTRIBUTION: Known only from the type locality.
