Accola spinosa Petrunkevitch 
Figures 12-13 
As pointed out in the last paragraph of my description of A. 
downeyi sp. nov., all six-eyed specimens now in my collection of the 
genus Accola from Boquete and El Volcan, Panama are transferred 
to A. downeyi sp. nov. 
Since the publication of my paper on this species in 1945 I have 
collected a large number of both sexes in the Panama Canal Zone and, 
especially, on Barro Colorado Island. Females as expected, far out- 
number males. In order to make the distinction clearer between this 
species and other eight-eyed forms such as A. petrunkevitchi Chicker- 
ing from Puerto Rico and A. simla sp. nov. from Trinidad I am 
including Figures 12-13. Special attention is directed to Figure 12 
which shows the division of the most ventral of the spines at the 
distal end of the first tibia. This division was noted in my 1945 
description. There is some variation in the appearance of these spines 
among males of this species; apparently in some specimens the two 
spines overlap to such an extent as to obscure one of them. Disarticu- 
lation of the first tibia and metatarsus reveals the division more 
clearly.
