males:
Total length, 13.0 to 16.0 mm.

Chelicerae 3.0 -3.7 mm 1.2-1.5 mm.
Propeltidium 1.5-1.7
2.3-2.8
Palpi
13.0-16..0 -
1st legs
9.5-12.0
-
4th legs 15.5-20.5

Holotype
larger.
Color in alcohol light to straw
yellow, with dusky purplish markings as follows: eye tubercle dark,
propeltidium dusky except for a light area on each side of eye tubercle
and a light, median, ovate area; mesopeltidium, metapeltidium, and
abdominal tergite irregularly marked; palpi dusky on tarsi, metatarsi,
tibiae, and apical ends of femora; legs dusky on apical ends of femora
and basal ends of tibiae. Malleoli white.
Dentition of chelicerae somewhat variable
but following general pattern of figures 20 and 21. Movable finger with
principal tooth large; two minute intermediate teeth located on and at
base of principal tooth; anterior tooth replaced by a rounded elevation,
margin of which armed with nodules forming the dorso-ectal edge of
mesial groove at tip of finger; mesial tooth absent. Fondal notch
obscure, somewhat narrower than width of fixed finger and bearing two or
three denticules. Fixed finger gradually tapered from base to tip which
is lightly hooked downward; ventral margin of finger bearing aborted
teeth which give it a
dentate profile.
Mesoventral groove of fixed finger distinct
apically but indistinct basally, apparently extending three-fourths of
length of finger. Flagellum complex consisting of dorsal row of striate
bristles, mesial row of plumose bristles that become striate apically,
and basal group of tubular bristles. Mesial plumose bristles of movable
finger extending nearly to apical end of articulation area.
Eye tubercle situated on anterior margin of
propeltidium. Eyes separated by less than a diameter. Propeltidium wider
than long by a ratio of 1 to 1.5.
Metatarsus, tarsus, and tibia of palpus
sparsely provided with large cylinder bristles below and short fine ones
above, as well as usual long, slender spines. Metatarsus of palpus
without scopula and about four times as long as tarsus.
First post-spiracular abdominal sternite
provided with two long slender ctenidia that extend well beyond anterior
margin of succeeding sternite (fig. 22).

Color and markings in alcohol same as in males except
dusky markingssomewhat fainter.
Dentition of chelicerae as shown in figures
23 and 24. Movable finger with principal tooth large, one intermediate
tooth nearer principal tooth, anterior tooth about two-thirds as large
as principal tooth, indistinct serration in front of anterior tooth, and
no mesial tooth. Fixed finger with principal tooth large, medial tooth
slightly smaller and anterior slightly smaller than medial tooth; one
intermediate tooth and one denticule between principal and medial teeth
and one intermediate tooth between medial and anterior teeth. Fondal
teeth same as in male.
Structure same as in male except first
post-spiracular abdominal sternite provided with only two trace ctenidia
scarcely distinguishable from abdominal setal clothing. Opercula
of genital segment as shown in figure 25.
