Holotype 2 Mona Island, 5 April 1944 (Serralles). 
Theridion insulicola differs from Theridion antillanum

median eyes narrower behind, and the black granules on 
the abdomen. These granules are very conspicuous, even 
after the long bristles have been broken off.

by Dr. W. W. Mann. It has the same number of tubercles 
on the abdomen as Marxia grisea McCook, American 
Spiders, 1893, 3, p. 195, pi. 13, fig. 10, described from a 
female, 8.00 mm. long, from Biscayne Bay, Florida. The 
two genera belong to separate sections of the family. The 
male of Marxia has two long bristles on the patella of the
