eroon, N09°05', E12°58' (15 January 1976; F. Puylaert) ( MRAC 148.331 ) .

ETYMOLOGY: The species’ epithet is a latinization of αβoνκoλητos, the classical Greek for ‘‘neglected.’’ The single specimen was at first not recognized as a separate species and classified as a somewhat aberrant form of H. robertus .

DIAGNOSIS: Females can be recognized by the concave scape of the epigyne, flanked by the sclerotized ID entrances, in combination with the diagonal, inward­running ID stretch and the ID loop posterior to ST1.

MALE: Unknown.

FEMALE: Measurements. Total length 2.57; carapace 1.24 long, 0.97 wide; length of fe: I 1.05, II 1.11, III 0.86, IV 1.24. Leg spination. Fe: I rv 3; IV plt 1 rlt 1; ti: I, II vsp 6; mt: III plt 1 vt 1 rlt 1; IV plt 1 vt 2 rlt 1. Coloration. Carapace yellow brown, chelicerae, legs, and sternum yellow. Abdomen pale apricot, no pattern, sparsely covered with thin, pointed grey setae. Genitalia. Epigyne a concave anterior scape with median blunt tooth pointing backward, flanked on both sides by heavily sclerotized entrances of IDs (fig. 28c). Vulva: first stretch of ID wide and thick walled, associated with cauliflower­like gland and followed by triangular loop, next by a diagonal, inward­running stretch, then by a hairpin loop between ST1 and finally by an ID loop posterior to ST1, connected to the latter (fig. 29d). Spermathecae 1 with conspicuous internal spikes.

DISTRIBUTION: Known only from the type locality.
