1, 2. “2 holotype and immature paratypes from Aca- 
pulco, Mexico, June 17, 1936 (L. I. Davis).” 
Male. Length, 1.5 mm. 
The male is much darker than the holotype hut the 
amount of color evidently depends upon the habitat. 
The eyes are more closely grouped than in the female 
and are on a low turret. The two black annulae on each 
joint of the legs are reduced to large lateral dots. The 
abdominal markings are typical of the genus and are 
very distinct. 
The palpus is large for the size of the spider. There 
are three conspicuous points all protruding from the 
cavity, a forked pair in the distal half and a longer point 
at the base. All are heavily chitinized. 
Allotype c? Mexico; Acapulco, 19 December 1944 (S. 
Jones). 3c? 5? Mexico; Acapulco, 18-19 December 1944 
(S. Jones). 
The male selected as an allotype was found under a 
rock and lias the dark marks on the cephalothorax and 
the abdomen much more distinct than the specimens 
found at the base of palm leaves, these are quite pale.
