Chickering — Genus Trachelas 
229 
7.93 mm; total length, excluding the chelicerae, 7 mm. Carapace 
nearly 3.25 mm long; 2.6 mm wide opposite second coxae where it 
is widest; nearly 1.35 mm tall in cephalic region a short distance 
behind PME where it is tallest ; in general, quite typical of the larger 
females in the genus. Eyes: eight in two rows as usual; posterior 
row wider than anterior row in ratio of nearly 5 : 4 and occupies 
nearly five-sixths of width of carapace at that level; otherwise 
essentially as in male. Ratio of eyes AME : ALE : PME : PLE 
= nearly 7 : 10 : 7 : 9. AME separated from one another by 
slightly less than their diameter and separated from ALE by nearly 
1.3 times their diameter. PME separated from one another by 
nearly two diameters and separated from PLE by nearly 2.5 times 
their diameter. Lateral eyes separated from one another by nearly 
1.2 times the diameter of ALE. Central ocular quadrangle wider 
behind than in front in ratio of 7 : 5 ; about as long as wide in front. 
Height of clypeus equal to diameter of AME. Chelicerae: robust; 
more geniculate in front near base than in male holotype ; otherwise 
essentially as in the holotype. Maxillae, lip and sternum all essentially 
as in holotype with minor variations. Legs: 4123 in order of length; 
otherwise essentially as in the holotype. Palpal tarsal claw very 
small. Abdomen : essentially as in the male holotype except for the 
epigynum which is obscurely distinctive; spermathecae and canali- 
culi very obscure (Fig. 27) ; lack of paratypes prevents more careful 
examination and clearer representation in drawings. Color in alcohol : 
cephalothorax, legs and mouth parts essentially typical of females 
of the genus with minor variations; abdomen essentially as in male 
with minor differences ; the dorsum is more clearly and finely speckled 
with minute yellowish dots; the transverse, lighter lines across the 
posterior part of the dorsum are clearer than in the male ; the venter 
is yellowish-brown in general; the epigastric region is quite well 
chitinized. 
Diagnosis. This species appears to be closely related to T. jamai- 
censis Gertsch but the male palpal features, the female epigynum, 
the relationships of the eyes and other less conspicuous features all 
seem to establish it as a new species. 
Record. Shortly before her death Miss Elizabeth Bryant had, 
apparently, selected the male and female treated here for description 
as a new species. They have been awaiting attention in the collections 
of the Museum of Comparative Zoology since that time. There are 
no paratypes of either sex available at the present time.
