Cameroons. SPARASSUS RUFILATUS, sp. n. (Plate LVI. figs. 13, 13 a.) d . Colour much as in S. trifurcatus, except that the legs are more orange-red, though the bases of the femora remain pale ; the upper-side of the abdomen studded with dark reddish-brown spots and the lower side behind the epigastric fold uniformly pinkish brown. Carapace very slightly longer thau wide, less than tibia of 3rd and than half the patella + tibia of 1st leg. Eyes of posterior line slightly procurved, subequal and subequally spaced; eyes of anterior line closer together, equally spaced, distance between medians about half their radius. Legs very long, 2nd surpassing 1st by its tarsus and one third of its protarsus ; 2nd leg about seven times as long as carapace. Tibia without apical inferior spines ; patellae unspined. Palp with tibia cylindrical, much longer than patella, and armed internally with a single long spine; patella unspined ; tibial apophysis consisting of a forwardly directed spur, the apex of which is pointed and hooked ; tarsus very large, its external edge concave, internal convex; palpal organ constructed as in fig. 13, Plate LVI. Measurements in millimetres.-Total length 14; length of carapace 6*5, width 6; length of 1st leg 40, of 2nd 45*5, of 3rd 29, of 4th 33 ; patella -f- tibia of 1st 14*8, tibia of 3rd 7*8. Loc. Cameroons, The females of the foregoing species may be recognized as follows :- a. Head narrower, its width only equal to the length between the anterior end of the fovea and the posterior line of eyes; eyes closer together, the ocular quadrangle scarcely narrowed in front; mandibles reddish brown ; tibia with 3 pairs of inferior spines ; patella; at least on 2nd and 3rd legs spined in front and behind benitensis, sp. n. b. Head broader, its width almost equal to the entire length measured from the apex of the fovea ; eyes more widely spaced, the ocular quadrangle distinctly narrower in front; mandibles black; tibias with two pairs of spines beneath; patella; unspined batesi, sp. n. The males of the species here described may be determined as follows:- a. Tibial process of palp trifurcate (tibias of legs without inferior apical spines; 2nd leg a good deal longer than 1st, and only a little more tban five times as long as carapace ; patella and tibia of palp without spines) ... trifurcatus, sp. n. b. Tibial process of palp simple, undivided. a1. Tibial process stout at base, its distal half slender and bent downwards almost at right angles ; tibias of legs with two pairs of inferior spines ; 2nd leg only a little longer than 1st, and less than six times as long as carapace; tibia of palp strongly spined benitensis, sp. n |
