details are obscure. Lip : somewhat longer than wide at base in ratio 
of about 8:7; deeply notched at narrowed distal end ; firmly united 
to sternum. Maxillae: moderately convergent; somewhat longer 
than lip but not meeting at distal ends; with lateral margins regularly 
rounded. Sternum: longer than wide in ratio of about 29 : 24; 
continued broadly between first and second coxae and narrowed 
between third and fourth; moderately convex; surface finely granu- 
late; posterior end between bases of fourth coxae which are separated 
by their width. All coxae basally lobed but first most conspicuously 
so; coxae 1423 in order of length. Legs: 4123 in order of length 
but fourth only slightly longer than first; tibial index of first leg 16, 
of fourth leg 13. Figures 2-3 show essential features of first leg with 
its robust femur, long patella, short metatarsus and short, clubshaped 
tarsus; several low cusps occur on the prolateral and ventral surfaces 
of the patella and tibia; the metatarsus has a series of ventral teeth 
difficult to observe clearly because of presence of scopulae; the first 
tarsus and metatarsus have conspicuous prolateral scopulae with 
considerable iridescence ; the tibia has an inconspicuous similar scopula ; 
somewhat similar scopulae appear on other legs but they are much 
less conspicuous. No tarsal claws have been found on the first legs 
but all others have a pair ; no teeth observed on them ; claw tufts are 
present and may obscure the teeth. Palp: essentials shown in Figures 
4-5 ; femur slender ; patella very short and rounded ; tibia swollen and 
nearly as broad as long. Abdomen: viewed from above, longer than 
wide in ratio of about 38 : 29; 2.47 mm long, 1.9 mm wide; broadly 
rounded at base and only slightly pointed posteriorly; with only two 
spinnerets ; with a conspicuous ventral scutum anterior to genital 
groove and extended dorsally to cover nearly the entire basal end of 
the abdomen. Color in alcohol : carapace, palps, chelicerae, lip and 
first legs a deep, reddish brown; other legs yellowish brown with 
variations; sternum only slightly lighter than carapace; abdominal 
scutum about the same as sternum with remainder of abdomen light 
yellowish brown. 
Female paratype. Total length 5.53 mm. Carapace 1.93 mm long; 
1.43 mm wide; about .65 mm tall; considerably less robust than in 
male. Eyes essentially as in male with minor differences. Chelicerae: 
in general as in male; fang groove apparently with only two very 
short teeth on ret remargin ; promargin with a row of several long, 
slender spines or teeth associated with a weakly developed scopula 
of long, slender hairs ; anterior surface finely corrugated but less 
flattened than in male. Lip, maxillae and sternum all essentially 
as in male holotype. Legs: 4123 in order of length; tibial index
