TYPES: Female holotype: between roots of low plants in forested swamp, elev. 1000 m, Katanga, Albertville region, Bendera, Congo S05°03', E28°54' (October 1958; N. Leleup) ( MRAC 112.902 ) .

ETYMOLOGY: The species is named amphibolus , a latinization of the Greek αμφιβoλos, ambiguous, because the vulva, with its posteriorly located entrances connected by a straight duct to a thickened, coiled part of the ID, seems to combine features of Hortipes species from Kivu with features of the South African species.

DIAGNOSIS: Females of H. amphibolus are recognized by the vulva, which has a thickened and coiled stretch of ID, connected to posterior entrances through a straight duct.

MALE: Unknown.

FEMALE: Measurements. Total length 2.59; carapace 1.00 long, 0.81 wide; length of fe: I 0.76, II 0.81, III 0.68, IV 0.92. 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, chelicerae and
