Chickering — Genus T marus

in form; not flattened; widened a little about 2/3 from base; a short 
distance posterior to widened region there is a small, median, dorsal 
tubercle corresponding to the more conspicuous tubercle in the fe- 
male ; other features essentially typical of the genus. Color in alcohol : 
carapace yellowish in general ; with many minute reddish dots and 
brownish spots and streaks impossible to describe in detail. Legs: 
yellowish with many small, reddish spots and streaks; first two pairs 
of femora with the characteristic mottled prolateral and retrolateral 
surfaces; third and fourth legs with more reddish spots than other 
legs. Sternum yellowish with small, pinkish dots irregularly distrib- 
uted near margin. Abdomen : dorsum pinkish in general ; a very 
narrow, reddish band extends across the widened region ; irregular, 
reddish streaks occur in the posterior third of the dorsum and an ir- 
regular, narrow, reddish band separated in the middle occurs about 
half way between the base and the widened region; lateral sides 
yellowish with reddish dotst and streaks; venter very light brown 
through the center flanked by whitish areas. 
Female paratype. Total length, including porrect chelicerae and 
somewhat extended spinnerets, 5.91 mm; total length from anterior 
border of clypeus to posterior end of anal tubercle 5.4 mm. Cara- 
pace 1.8 mm long; 1.65 mm wide; about .7 mm tall; with about 
twelve long, slender spines around border of posterior declivity. 
Eyes : curvature of rows essentially as in male. Central ocular quad- 
rangle wider behind than in front in ratio of about 3:2; wider be- 
hind than long in ratio of nearly 4:3. Ratio of eyes AME : ALE : 
PME : PLE = 5 : 12 : 7 : 10. AME separated from one another 
by a little more than three times their diameter; from ALE by 
slightly more than 3.5 times their diameter. PME separated from 
one another by about 3.5 times their diameter, from PLE by a little 
more than 4.6 times their diameter. Laterals separated by 2.3 times 
the diameter of PLE. Height of clypeus nearly equal to eight times 
the diameter of AME. Chelicerae, maxillae, lip and sternum all typi- 
cal of females of the genus. Legs: 123 — 4 in order of length; spines, 
tarsal claws, palpal claws and trichobothria all typical of females of 
the genus studied by the author. Abdomen : considerably more robust 
than in male; much widened two thirds from base and then sharply 
narrowed to posterior end ; posterodorsal tubercle somewhat more 
prominent than in male (Fig. 14). Epigynum : obscurely distinctive; 
unlike any other seen in the genus from the Neotropical region; es- 
sential features shown in Figure 15; some variations noted among 
paratypes. Color in alcohol: essentially like that of male.
