A NEW ACANTHOCTENUS 
(ARANEAE: ACANTHOCTENIDAE) 
FROM JAMAICA, W. I. 1 
By Arthur M. Chickering 
Albion College, Albion, Michigan 
About twenty-five species are known in this family and all have 
been assigned to the Genus Acanthoctenus Keyserling, 1876. These 
have been reported all the way from Mexico to Argentina. So far as 
I have been able to learn, however, no representative has ever been 
recorded from the West Indies. It is, therefore, of considerable in- 
terest to be able to report that both sexes of what I am compelled 
to regard as a new species have been collected in several localities 
in Jamaica, W. I. A holotype male and an allotype female have been 
selected and are described in accord with my usual formula in this 
brief paper. These types are being deposited in the Museum of Com- 
parative Zoology at Harvard College, Cambridge, Mass. 
Genus Acanthoctenus Keyserling, 1876 
Acanthoctenus remotus sp. nov. 
(Figures 1-6) 
Holotype male. Total length 11 mm. (somewhat exaggerated be- 
cause of softened and stretched condition of the specimen in the region 
of the pedicel). Carapace 5.59 mm. long; 4.55 mm. wide opposite 
second coxae where it is widest ; well rounded from opposite posterior 
eyes to posterior border; median longitudinal thoracic groove deep and 
long. 
Eyes. Eight in three rows, two, four, two; essentially as in the 
Ctenidae (Fig. 1). Viewed from above, both rows recurved; viewed 
Tublished with the aid of a grant from the Museum of Comparative Zool- 
ogy at Harvard College.
