their diameter. Lateral eyes separated from one another by nearly 
1.5 times the diameter of ALE. Central ocular quadrangle wider 
behind than in front in ratio of nearly 17 : 12; only slightly longer 
than wide in front. Height of clypeus nearly equal to seven-tenths 
of the diameter of AME. Chelicerae: robust; geniculate near base; 
surface distinctly granulose; somewhat concave along medial surfaces; 
keeled along most of the medial margins; lateral margins gently 
curved ; fang regularly curved ; fang groove with three teeth along 
promargin, outer one small and probably with only two along retro- 
margin; with a moderately well developed basal boss and a well 
developed scopula along promargin of fang groove. Maxillae: quite 
typical of males of the genus in general; distal, lateral corner well 
rounded and without any extension such as occurs in T. ecudobus 
sp. nov. (Fig. 1). Lip: nearly three-fifths as long as maxillae; only 
slightly longer than wide; with basal marginal indentations moder- 
ately well developed. Sternum: moderately convex; longer than 
wide in ratio of nearly 4 : 3 opposite interval between second and 
third coxae where a narrow extension passes outward for a short 
distance between second and third coxae; bluntly just opposite bases 
of fourth coxae which are separated by slightly more than half their 
width ; only moderately rebordered ; surface finely granulose ; anterior 
border gently trilobed (Fig. 2). Legs: 1243 in order of length; first 
leg most robust; spines appear to be lacking; third metatarsus with 
a fairly well developed brush ; with few small cusps on first tibiae, 
metatarsi and tarsi and still fewer on these segments in second legs. 
Palp: typical of males of the genus in general; most distinctive fea- 
tures are in the bulb and its embolus; Figures 3 and 4 show the 
essential features; the tibial apophysis is very short and inconspicu- 
ous. Abdomen: quite typical of males of the genus in general; a 
small, faintly visible, dorsal scutum is present. Color in alcohol: 
carapace and chelicerae a rich, reddish brown essentially typical of 
the genus ; sternum a light brownish ; first femur nearly like sternum ; 
other legs yellowish with some variation; abdomen light yellowish, 
nearly white with the dorsal scutum weakly chitinized; the four 
muscle impressions barely visible. 
Diagnosis. This species seems to be closely related to T. bicolor 
Keys, but the features of the palp establish it as a new species. 
Record. The female is unknown and there are no male paratypes.
