THE MALE OF MECYNOMETA GLOBOSA 
(O. P.-CAMBRIDGE) (ARANEAE, ARGIOPIDAE) 
By Arthur M. Chickering 
Museum of Comparative Zoology 
The female of this species was described from Guatemala by the 
elder Pickard-Cambridge in 1889. Apparently it was known only 
from that part of Central America until Dr. Petrunkevitch reported 
a female specimen from the Wilcox camp on the San Lorenzo River 
in Panama in 1925. Mr. Banks reported two females from the Pan- 
ama Canal Zone in 1929. I now have in my collection about two 
dozen females from several localities in the Canal Zone and El Valle, 
Panama. Only three males have appeared in the collection and all 
were collected in 1934 and 1936. Mecynometa is an interesting genus 
with a total of seven species now known. Simon described a species 
from the African Congo; five species have been described from South 
America; M. globosa (O. P.-Cambridge) is now known from two 
countries in Central America. Because males have hitherto been 
unknown I have thought it worth while to describe one of these in 
this brief paper.
