Carapace yellowish brown, covered with whitish hairs, reddish hairs around the eyes ; mandibles pale yellow, sparsely speckled with black, scantily clothed with yellow hairs; mouth-parts yellow ; sternum yellow, blackish at the sides, mottled with yellow and white hairs ; palpi yellowish brown, mottled with black ; legs brownish, femora infuscate distally, the anterior pairs also infuscate beneath and spotted with black at the base of the spines above, patella? fuscous, tibia? distally infuscate, 3rd and 4th pairs with superior distal spot, protarsi yellowish indistinctly speckled with black; abdomen clothed laterally and below with whitish hairs, with four white spots and two parallel lines on the area between the epigastric fold and the cribellum ; the upper surface covered with darker hairs, with a low crest of hairs passing transversely in front of the prominences and curving backward on the sides. Carapace nearly twice as long as wide, its length equal to that of tibia of 3rd leg, a little more than one third that of the 1st protarsus, less than half (about two fifths) the length of the 1st femur; cephalic area a little wider in front than behind ; superciliary ridges evenly rounded, not prominent or produced into horn or tooth ; the posterior median eyes close together, their radius exceeding the height of the clypeus, anterior medians about two diameters apart. Palpi very slightly longer than carapace. Legs 1, 2, 3, 4 ; 1st twice as long as 3rd, 1st exceeding the 2nd by half its protarsus and its tarsus ; 3rd reaching to apex of tibia of 2nd when both are extended; on the femora of the 1st and 3rd the anterior spines are supported on tubercles which also support small tufts of hair. Abdomen rather more than twice as long as wide, posteriorly pointed and compressed, widest just in front of the middle, where it rises into a pair of prominences, from which it narrows anteriorly and posteriorly. Measurements in millimetres.-Total length 19 ; length of carapace 7, width 4; length of abdomen 12, width 5; length of 1st leg 58, of 2nd 45, of 3rd 29, of 4th 28. Loc. Benito Biver (G. L. Bates); a single $ example. This new species may be at once recognized from D. anchietce (Dinopis anchietce, Brit. Cap. loc. cit. p. 15, pl. ii. figs. 2-2 c), from Bio Quilo, Angola, by the absence of triangular superciliary crests, the greater length of legs, flatter and longer carapace, proximity between posterior median eyes, & c In D. anchietce the eyes are concealed by the crests when viewed from above and are nearly a radius apart; the thoracic portion of the carapace is as wide as long, and although the length of the trunk is about the same as in D. aspectans, the anterior leg measures only 41 m m . instead of 58. 55* |
