FIVE NEW SPECIES OF THE GENUS TMARUS 
(ARANEAE, THOMISIDAE) FROM THE WEST INDIES 
By Arthur M. Chickering 
Museum of Comparative Zoology 
The Genus Tmarus Simon, 1875, is widely distributed in Europe, 
Asia, Africa, Australia and in the Americas. This is especially true 
of South America. It appears to be abundant and highly diversified 
into species in the Neotropical region. At the present time thirty 
species are known from Panama alone. But, so far as I have been able 
to determine, the genus has not been reported from the West Indies 
until the present time. I was much interested, therefore, to find 
several species of this genus in my collections made during the last 
few years in Jamaica, Puerto Rico and Trinidad. These have now 
been carefully studied with the result that I am obliged to recognize 
five new species from these islands. Two of these species are known 
from both sexes; two are known only from males and the remaining 
one is known only from the female. These five species are described 
in the following pages of this brief paper and may be listed as follows: 
Tmarus crane ae sp. nov . ; T. farri sp. nov. ; T. insuet us sp. nov. ; 
T. menotus sp. nov. ; T. vertumus sp. nov. The types will be deposited 
in the Museum of Comparative Zoology at Harvard University. 
Grant No. GB-1801 from the National Science Foundation made 
it possible for me to spend seven months making collections of spiders 
in the West Indies and Panama during the latter part of 1963 and 
the first five months of 1964. This grant is also making it possible for 
me to continue my studies at the Museum of Comparative Zoology 
for a considerable period. A Guggenheim Fellowship made it possible 
for me to collect in Jamaica, W. I. and in Panama in 1957 and 1958 
and also to spend four months in the British Museum (Natural His- 
tory). Dr. G. Owen Evans and Mr. D. J. Clark, Department of 
Zoology (Arachnida), British Museum (N. H.) have recently 
loaned me valuable specimens of the genus Tmarus to help me in my 
studies. As I have frequently stated in my published papers, I am 
deeply appreciative of the many privileges extended to me by the staff 
of the Museum of Comparative Zoology, Harvard University, over a 
period of many years. My studies could never have been carried on 
as they have been continued without this encouragement. Special 
acknowledgements should be extended to Dr. Ernst Mayr, Director;
