TWO NEW SPECIES OF THE GENUS ACC OLA 
(ARANEAE, DIPLURIDAE)*

Up to the present time six species of the Genus Accola Simon 
have been described from parts of South America, Central America 
and the West Indies. One of these, A. spinosa Petrunkevitch, has 
been known from both sexes since 1945; two of the others described 
by Simon are known only from immature specimens; the remaining 
three species are known only from females, which have very few dis- 
tinguishing features. Dr. Petrunkevitch (1929) described a mature 
female of the genus Accola from Puerto Rico and considered it to 
belong to the species he originally described from Panama. Since 
the publication of my brief paper on A. spinosa Petrunkevitch (1945) 
and of the description of a male for the first time, I have collected 
a considerable number of specimens of this genus, from Panama, 
Jamaica and Puerto Rico. It is now quite clear that the Puerto Rican 
species is not the same as the species common in Panama and that 
the species from Jamaica appears to be quite different from other 
known species. Dr. Petrunkevitch stated that the Puerto Rican 
species had been taken with a sweeping net but I have taken all of 
my numerous specimens from debris of one kind or another by shak- 
ing or sifting. In order to bring our knowledge of this genus up to 
date I have thought it worth while to publish descriptions of these 
new species, both containing males and females. The types will be 
deposited in the Museum of Comparative Zoology at Harvard Uni- 
versity. Female paratypes will also be deposited in the American 
Museum of Natural History and in the Museum of the Institute 
of Jamaica, Kingston, Jamaica, W. I. 
At this time I wish to express my appreciation to the National 
Science Foundation for Grant No. GB-1801, which made it possible 
for me to collect in the West Indies and Panama for seven months. 
The grant also provides assistance for a period of study on my col- 
lections in the Museum of Comparative Zoology. My gratitude and 
appreciation are also again expressed for the priviledge of working 
in the Museum of Comparative Zoology at repeated intervals over 
a period of many years. Publication and library privileges together 
with continued encouragement from directors and staff members have 
been indispensable for the continuation of my studies.
