THE GENUS CORINNA (ARANEAE, CLUBIONIDAE) 
IN PANAMA 
By Arthur M. Chickering 
Museum of Comparative Zoology, Harvard University 
In 1937 I reported five species of the genus Corinna from Barro 
Colorado Island, Panama Canal Zone as follows: Corinna bulbosa 
F. P. -Cambridge, C. crassipalpis Chickering, C. mucronata F. P.- 
Cambridge, C. robusta Chickering, C. silvatica Chickering. These 
were all identified from my collection of 1934. Since that date 
numerous specimens of Corinna have accumulated as a result of 
of several additional field trips in Panama. These are all being 
placed in the Museum of Comparative Zoology. While preparing 
these specimens for integration into the collections I have identified 
several species not recognized in 1937. Four of these appear to 
represent new species. As a result of my study of all specimens now 
available I believe that I am able to report a total of twelve species 
of the genus Corinna now known from Panama. These may be 
listed as follows: C. bulbosa F. P.-Cambridge ; C. bulbula F. P.- 
Cambridge; C. casueta sp. nov. ; C. crassipalpis Chickering; C . gras- 
sima sp. nov.; C. luteomaculata Petrunkevitch ; C. mucronata F. 
P.-Cambridge; C. nervosa F. P.-Cambridge; C. perida sp. nov.; 
C. robusta Chickering; C. silvatica Chickering; C. tenubra sp. nov. 
Six of these are known from both sexes, four are known only from 
males and the remaining two are known only from females. 
Genus Corinna C. L. Koch, 1842 
During my study of this genus from Panama I have found that 
males have quite distinctive tibial and tarsal palpal features with 
little variation among individuals of a species. Females, however, 
appear to have only obscurely distinctive epigynal features and with 
a rather high degree of variation among specimens of a single spe- 
cies. It is my opinion that a thorough revisional study of the whole 
genus is needed.
