THREE NEW SPECIES OF ACCOLA 
(ARANEAE, DIPLURIDAE) 
FROM COSTA RICA AND TRINIDAD, W. I * 
By Arthur M. Chickering 
Museum of Comparative Zoology 
The genus Accola Simon was established in 1889 on the basis of 
an immature specimen of A. lucifuga Simon from Venezuela. During 
the next thirty-six years eight additional species were recognized. 
Three of these were from Luzon and New Guinea and all were 
described from females alone. The remaining five were from St. 
Vincent, W. I., Panama, Chile and Venezuela. Two of these, one 
from Venezuela and one from Panama, were described from imma- 
ture individuals. The remaining three species were all described 
from females alone. In 1945 I was able to describe the male of 
A. spinosa Petrunkevitch together with mature females. In 1964 I 
was able to describe both sexes of A. petrunkevitchi from Puerto 
Rico and both sexes of A. lewisi from Jamaica, W. I. During the 
past few months I have been able to recognize a new species of this 
genus taken in a recent collection in Costa Rica and two new species 
in a collection made in Trinidad, W. I. in April, 1964. These last- 
mentioned three species are described in the following pages of this 
brief paper. The present status of the Genus Accola Simon, 1889 
may, therefore, be stated as follows: fourteen species are now recog- 
nized; six of these are known from both sexes; two are known only 
from immature specimens; the remaining six species are known only 
from females. I think it safe to predict that numerous additional 
species will become known as soon as careful collecting is carried out 
in South America and the West Indies. The greater portion of my 
collection of this genus has come from weed and hay debris with 
leaf debris considerably less productive. 
All specimens relating to the new species described in this paper 
will be deposited in the Museum of Comparative Zoology at Harvard 
University. In my study of the genus Accola I have noted irregu-
