as in male but carapace with pale areas more extensive and leg I 
lacking dark area at base and lacking setal fringe. Epigynum rather 
long (ratio of epigynal length to greatest septal width more than 
2:1); median septum with expanded posterior part approximately 
triangular in outline and concave at lateral margins (Fig. 74); 
copulatory tubes with small swellings at base (Fig. 75). 
Diagnosis. Specimens of P. longivulva can be distinguished from 
those of the other species in the milvina group by the combination 
of black carapace margins, presence of a setal fringe on tibia and 
basitarsus I of males, rather long and slender terminal apophysis, 
long epigynum (ratio of epigynal length to greatest septal width 
more than 2:1), small swellings at base of copulatory tubes, and 
occurrence restricted south of the Tropic of Cancer. 
Range. Tabasco, Mexico to Guatemala. 
Natural History. Adults have been collected in February, March, 
and June. One of the females collected in February had an egg sac. 
Habitat is not recorded.
