Show 1897.] MR. R. I. POCOCK ON ETHIOPIAN SPIDERS. 745 Ceratogyrus, nov. Pterinochilus, nov. Selenocosmiinae ( = Selenocosmieae in part, Pcecilotherieae in part, Ischnocoleae in part, and Phlogieae). Theraphosinae (=Selenocosmieae in part, Pcecilotherieae in part, Ischnocoleae in part, Chaetopelmateae, Avicularieae, Theraphoseae, Eurypelmateae, Homaeommateae). The Ethiopian genera known to m e may be recognized by the following characters : a. Outer surface of the mandible furnished above with a thick scopula or pad of feathery hairs; (tarsal scopulae entire ; claws not toothed ; anterior tibia of male with a single curved spine-tipped spur ; posterior sternal sigilla marginal).-Subfamily HARrACTIRIN^E. a'. Thoracic fovea very deep and nearly circular, circumscribing a central tubercular prominence, as in the Central American genus Sphmrobothria; mandible and spinners as in Pterinochilus V. Thoracic fovea normal, transverse. a2. Inner surface of mandible without feathery scopula; no stridulating organ, the inner surface of the maxilla between the oral fringe and the suture sparsely beset with simple setae, the adjacent area on the mandible without rows of modified bristles ; apical segment of posterior spinners longer than the second... b2. Inner surface of mandible with feathery scopula above; with stridulating organ, the area on the maxilla mentioned above bearing a thick cluster of notes in the form of feathery hairs, the adjacent area on the mandible below the external scopula with at least one series of modified setae; apical segment of posterior spinners shorter than the second ... b. Outer surface of mandible not furnished with scopula of plumose hairs, at most sparsely beset with normal bristles.-Subfamily THERAPHOSINJE l. a3. Thoracic fovea forming a round or transversely elongate pit. a*. Protarsi and tibiae of legs armed with many strong spines ; protarsal scopulae scanty, not extending to the base of the segment on the legs of the 1st and 2nd pairs ; scopula of 4th tarsus divided by a complete band of setae; anterior tibia of male without spur ... 64. Leg with at most a few small spines at apex of tibiae and protarsi beneath; protarsal scopulae thick, extending to base of segments on legs of 1st and 2nd pairs; scopula on tarsus of 4th leg entire, or at most weakly (Scodra) divided in the adult. a5. Sternal sigilla submarginal ; ocidar area wide; without spines on the tibiae of legs; scopulae broad and very thick; legs and body thickly hairy; claws with a few small teeth; anterior tibia of male without spur Harpactira, Auss. Miaschistopus, nov. Scodra, Becker. 1 For another and more natural grouping of the genera of this section, see Supplement, p. 773. |
