I have been much interested in Eleteroonops spinimanus (Simon) 
for many years. Simon (1891) described the species from females 
collected on St. Vincent, B. W. I. In 1892 he reported the species 
from Venezuela. Dr. Petrunkevitch, in his study of Puerto Rican 
spiders, (1929), stated that he had males and females for study in 
the collection of the American Museum of Natural History. These 
were collected in 1915 in San Juan, Cayey, Naranjito and Coamo 
Springs. He regarded the males, taken in these localities, as belong- 
ing with the females and described a male from San Juan as the 
male of Oonops spinimanus Simon. This identification has been 
widely accepted up to the present time. I have had the specimens 
that were apparently studied by Dr. Petrunkevitch also on loan from 
the American Museum of Natural History. It has been very dis- 
appointing to find almost all of the specimens, believed to be those 
studied by Dr. Petrunkevitch, in a very dismembered and almost 
useless condition. I think there is no question about the status of the 
females involved but I am obliged to regard the identification of the 
males as open to serious doubts. Dr. Petrunkevitch noted a con- 
siderable degree of variation among the males in respect to the 
appearance of the palpal conductor and embolus, indicating, perhaps, 
a mixture of species. I have spent much time in searching through 
my extensive collection of O'onops /or males which could be matched 
with the well established females but without success. I am of the 
opinion that the males identified as Oonops spinimanus Simon by 
227
