Diagnosis. Oxyopes chiapas is related to other members of the 
acleistus species group based upon its color pattern and genital struc- 
ture. It is probably closest to O. summits, but is easily distinguished 
from this species and all others by the structure of the female geni- 
talia (Figs. 33, 34) and the male palpus (Figs. 92, 93).
