TYPES: Male holotypeand paratypecollected among dry fern leaves, Ruwenzorinorth slope, Kikuracamp, valley of the Ruanoli, Kivu, Congo N00°35', E29°57'( July–August 1974; M. Lejeune) ( MRAC 154.105). Paratypes: 16 together with holotype; 2♀at elev. 2000 m, Ruwenzori Nslope, Kikuracamp, Kivu, Congo N00°35', E29°57'( July– August, 1974; M. Lejeune) ( MRAC; 1♀in AMNH); 1♀on overhanging soil, elev. 1700 m, Kahuha Forest, km 7 on the road ButemboBeni, Kivu, Congo N00°09', E29°17'( 15–20 April 1974; M. Lejeune) ( MRAC).
ETYMOLOGY: The species is named in hon or of the reverend M. Lejeune, who collected the typespecimens.
DIAGNOSIS: Males of H. lejeuneiare rec 78 BULLETIN AMERICAN MUSEUM OF NATURAL HISTORY NO. 256 Fig. 23. a, b. Hortipes falcatus, new species. a.Vulva, ventral view. b.Vulva, schematic representation. Arrow indicates ID entrance. Scale line: 0.1 mm. flap. Females are close to those of H. falcatusand H. narcissusbut differ from both species by the entrances of the IDs, which are separated by more than half the width of the entire vulva in H. lejeunei.
MALE: Measurements.Total length 2.57; carapace 1.16 long, 0.97 wide; length of fe: I 0.95, II 1.03, III 0.78, IV 1.16. 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 orange yellow, lighter at the fovea. Chelicerae, legs, and sternum yellow. Abdomen yellowish white, no pat dorsal rim, thus delimiting smaller proximal triangle, and with small toothshaped anterior spike, pointing inward; cymbium with large, illdefined retrolateral bend with series of widely spaced long setae; sperm duct with wide basal part and not much narrower distal part with shallow turn just in front of embolus; MA large, curved down and sickle shaped and with large, thin indented flap along dorsal median margin; embolus with fairly broad, triangular base, long, whiplike, looped over 450° (fig. 24a, b). FEMALE: Measurements.Total length 2000 BOSSELAERS AND JOCQUÉ: HORTIPES79 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 orange brown, chelicerae, and sternum yellow, legs orange yellow. Abdomen peach, no pattern. Genitalia.Epigyne a slightly curved transversal slit (fig. 24c). Vulva: entrances of IDs separated by more than 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. 26a, b). OTHER MATERIAL EXAMINED: 16 inhumic substrate in forest, Itombwe, Uvira region, Mulenge station, Nyalengwe, elev. 2300 m, Kivu, Congo S03°07', E29°00'( November 1959; N. Leleup) ( MRAC); 1♀by sifting forest litter, elev. 2300 m, INRS site, 4 kmW of Pindura, Nyungwe Forest, Rwanda S02°29', E29°13'( 7 November 1985; Jocque´, Nsengimanaand Michiels) ( MRAC). VARIABILITY: The shape of the sickleshaped RTA process and the exact course of the coils and loops of ID are somewhat variable.
DISTRIBUTION: Kivu, Congoand SW Rwanda, between elev. of 1700 and 2300 m.
