 Chelicerae. Only slightly porrect, considerably divergent; with several white lanceolate hairs on basal half in front; with a fairly robust tooth in front about three fifths from base; basal segment .38 mm. long; no basal boss observed. Fang of moderate size and length; moderately sinuous; with a definite small tooth on inner margin about one fourth from tip. Fang groove distinct, moderately excavated in middle; promargin with two teeth near medial end of groove, a very small tooth and a much larger one, both arising from a common base; retromargin with the remains of the fissidentate tooth much reduced, with the "hammer-headed" process only moderately developed (Figs. 363-364, taken from paratypes to avoid serious injury to the holotype).

Maxillae. Slightly convergent; longer than wide in ratio of about 2 : 1; only moderately notched in middle of outer border; with well developed scopula along truncature; outer distal corner well rounded, but with a very minute tubercle (not visible unless maxilla is removed for examination).

Lip. Wider than long in ratio of 6 : 5; basal excavations very short, obscure; reaches to about the middle of maxillae. Sternal suture straight.

Sternum. Scutiform, quite convex; longer than wide in ratio of 23 : 20; anterior border as wide as base of lip; first coxae separated by thirteen twentieths of the width of the sternum; widest between second coxae; posterior end bluntly rounded, not extended between fourth coxae which are separated by three tenths of their width.

Legs. 1423. Tibial index of first leg 16, of fourth leg 13.

All legs with a moderate supply of hair but no fringes or tufts.

Spines. First leg: femur only dorsal 0-1-1-1; patella 0; tibia only ventral 2-2-2; metatarsus only ventral 2-2. Second leg: femur only dorsal 0-0-1-1; patella and metatarsus as in first; tibia only prolateral 0-1, ventral 0-1r-0. Third leg: metatarsus 0-1 prolateral; elsewhere 0. Fourth leg: femur dorsal 0-1-1-0; patella and tibia 0; metatarsus as in third. Palpal spines: apparently only femur dorsal 0-0-1.
