Show 1897.] MR. R. I. POCOCK ON ETHIOPIAN SPIDERS. 737 about equalling their thickness ; the posterior spinners are long and slender, longer than the carapace, the second and third segments about equal and longer than the first; the third segment not flexible. The labium and basal part of maxlllce are spinulose ; the sternum oval with posterior sigilla submarginal. In the possession of ungual tufts this genus appears to be peculiar in the family Dipluridae. For the rest it falls into the Diplureae in having the tarsi and protarsi scopulate, the tarsi unspined, and the anterior spinners close together, and into the Macrotheleae iu having the claws armed with a single series of teeth. HETEROTHELE SPINIPES, sp. n. (Plate XLI. fig. 6.) 3. Colour (specimen mostly rubbed). Carapace and limbs chestnut-brown, ocular tubercle and mandibles blackish; clothed with yellowish-brown hairs. Carapace about as long as the patella and tibia of the 3rd leg, less than protarsus of 4th. Eyes of anterior line very slightly procurved, the medians considerably larger than the laterals, the space between the medians rather greater than their radius, that between the medians and laterals rather less than the radius of the medians ; posterior laterals smaller than anterior laterals, space between them about equal to short diameter of posterior laterals; median laterals considerably smaller than posterior laterals, the space between them about equal to half the .space between the anterior and posterior medians. Mandible armed below with 10 teeth, granular behind. Legs 4, 1, 2, 3, long and slender ; segments all normal; patella and tibia of 1st and 4th about equal, protarsus of 4th equal to protarsus and half the tarsus of the 1st; tibia and protarsus of 1st less than tarsus and protarsus of 4th ; femora with spiniform setae above, armed near the tip on the inner side wdth 1 spine, also 1 outer spine on the femur of the 3rd ; patella of 3rd with an anterior and a posterior spine; tibia of 1st with 4 inferior spines (2 apical) and 1 anterior spine; tibia of 2nd with an extra anterior spine; tibia of 3rd and 4th with about 9 spines ; protarsi also strongly spined. Palp projecting past the patella of the 1st leg; its tibia about one-third longer than its patella, sometimes armed with an inferior spine; tarsus short, bilobate and weakly scopulate; the spine of the palpal organ slightly curved, stout basally, slender apically, but a little incrassate just before the tip, which though fine is truncate and very slightly bifid. Measurements In millimetres. Total length 16; length of carapace 7, width 5-8; length of palp 10-5, of 1st leg 24, of 2nd 21, of 3rd 20, of 4th 26-5; posterior spinner 8. Loc. Ugogo, German East Africa (Emln Pasha). A single male example. |
