essentially as in male. Eyes: six; essentially as in male. Chelicerae: 
in general as in male holotype; promargin of fang groove with eleven 
small but clearly defined teeth ; the cluster of very minute teeth along 
obscure retromargin has about 19 or 20 in the group. Lip and 
sternum: essentially as in male holotype. Legs: 4123; tibial index 
of first and fourth legs 12; spines essentially as in male; trichobothria 
observed on tarsi, metatarsi, tibiae and patellae as well as on palpal 
segments; palpal claw finely dentate. Abdomen: typical of females 
of the genus; second pair of lungs clearly delineated. Epigynum : 
with a well defined plate ; posterior margin procurved ; typical of 
females of the genus. 
Type locality. The male holotype and the described female para- 
type are from Turrialba, Costa Rica, July 25 to August 15, 1965. 
Four male paratypes and about three dozen females and immature 
specimens were taken in the same general locality and during the 
same period. In 1945 when I described the mature male and mature 
female of A. spinosa Petrunkevitch I also had a few mature females 
from Boquete, Panama with only six eyes. These six-eyed specimens 
were then regarded as deviates of A. spinosa Petrunkevitch as ex- 
plained in a footnote, page 1. Since that time numerous females and 
three mature males from Boquete and El Volcan, Panama have been 
collected. These are all six-eyed and agree well with my specimens 
of Accola downeyi sp. nov. For this reason they are, therefore, 
transferred to this species.

The name of the species is a noun used in apposition after the 
type locality. 
Male holotype. Total length from clypeus to posterior end of 
abdomen 3.38 mm; from anterior border of porrect chelicerae to 
posterior end of abdomen 3.64 mm. Carapace 1.52 mm long; 1.1 
mm wide opposite second coxae where it is widest ; 0.4 mm tall ; other 
features typical of males of the genus. Eyes: eight essentially as in 
A. petrunkevitchi Chickering from Puerto Rico; all arranged on a 
low tubercle (Fig. 6) ; viewed from above, posterior row strongly 
recurved; AME dark and difficult to distinguish; all others white; 
ratio of eyes AME : ALE : PME : PLE = 2 : 1 1 : 6.5 : 10.5 ; 
AME separated from one another by about their diameter; only 
slightly separated from ALE ; ALE separated from one another in 
front by about one sixth of their diameter; PME separated from 
one another by about one sixth of their diameter; PME separated
