Color in alcohol white to light yellow, with dusky purplish markings as
in T. andreasana except mesopeltidium, metapeltidium, and
abdominal tergites light and there are two faint dusky stripes on
chelicerae.
Dentition of chelicerae as shown in figures
26 and 27. Movable finger evenly curved from base to tip, principal
tooth small, intermediate and anterior teeth missing, apical sixth of
finger formed into mesially facing, cup-like structure, mesial tooth
absent. Fondal notch obscure and without denticules. Fixed finger
lightly curved upward, abruptly narrowed and hooked downward at tip;
ventral margin of finger undulate but not bearing aborted teeth.
Mesoventral groove of fixed finger distinct
and occupying most of length of finger. Flagellum complex typical of
group, with apical striate and plumose bristles strikingly prominent.
Mesial plumose bristles of movable finger restricted to base of
articulation area. Eye tubercle situated on anterior margin of
propeltidium. Eyes separated by about one diameter. Propeltidium wider
than long by a ratio of 1 to 1.1.
Eye tubercle located on anterior margin of
propeltidium, with eyes separated by slightly more than one diameter.
Propeltidium wider than long by a ratio of 1 to 1.3.
Metatarsus, tarsus, and tibia of palpus
with usual clothing of cylinder bristles and long, slender spines.
Metatarsus without scopula but with two unequal rows of stout spines and
about four times as long as tarsus.
First post-spiracular abdominal sternite
with four long, slender ctenidia extending well beyond anterior margin
of succeeding sternite (fig. 28). Middle pair slightly shorter.

Female allotype larger.
Color and markings in alcohol similar to those of male.
Dentition of chelicerae similar to that of
T. andreasana except there are two intermediate teeth in front of medial
tooth of fixed finger.
Structure similar to that of male except ctenidia on first post-spiracular
abdominal sternite scarcely distinguishable from setal clothing.
