shining; with numerous stiff, dark colored hairs; posterior end with 
a tuft of stiff, dark colored hairs; nearly as wide as long; blunt 
posterior end extended somewhat between fourth coxae which are 
separated by nearly their width. Legs: 4123 in order of length; 
first and second legs with few spines but with many coarse hairs and 
bristles; third and fourth legs with several long, slender, transparent 
spines somewhat difficult to distinguish. Palp: with distinctive fea- 
tures essentially as shown in Figure 50; only tarsus with special 
modifications. Abdomen : ovoid ; epigastric scutum slightly chiti- 
nized ; typical in general of males of the genus. Color in alcohol : 
cephalothorax, legs and mouth parts yellowish with some variations; 
abdomen nearly white with three pairs of small, greenish spots on 
the venter just anterior to the spinnerets. 
Female paratype. Total length 1.89 mm. Carapace 0.77 mm 
long; 0.55 mm wide; nearly 0.26 mm tall; otherwise essentially as 
in male. Eyes: ratio of eyes ALE : PME : PLE = nearly 6 : 6 : 5 ; 
otherwise essentially as in male. Chelicerae, maxillae, lip, sternum, 
legs and spines all essentially as in male; details regarded as un- 
necessary with paratype. Abdomen : essentially as in male except 
for the epigynal area and related scuta; with a weakly outlined 
epigastric scutum; just behind this scutum is a narrow, chitinized 
band apparently representing the ventral scutum; epigynal area 
obscurely distinctive (Fig. 51). Color in alcohol: essentially as in 
male in general; the dark, subsurface spots just anterior to the spin- 
nerets are brownish in color. 
Diagnosis. This is the last of the group of five species whose 
relationships to already known species has been difficult to deter- 
mine. I believe that the features of the ocular area., the shape of 
the carapace, the features of the male palp and the epigynal area 
of the female establish it as a new species. 
Records. The described female paratvpe was taken in the same 
locality and on the same day as the male holotype. A male and a. 
female collected by Dr. N. A. Weber in Trinidad, W. I. but with 
no date indicated are now in the collection. In April, 106a. I col- 
lected three males and ten females in the vicinity of Simla, Trinidad, 
W. I.
