Diagnosis. Males of A. sanjacintensis sp. nov. are similar to those of A. polli (see Figs 12,13; Jocqué, 1991:35, figs 48-51, 94) by the simpLe VentraL tibiaL apOphysis, the origin and shape of the cymbium basal projection and by the size, direction and shape of the median apophysis. However, can be distinguished by having the retrolateral tibial apophysis with the distal area shorter and acuminate at the tip, narrower and longer proximal tegular apophysis and by the shorter and bent conductor than in A. polli ( Figs 3-5 ; 8,9; 14-17). The females resemble those of the A. polli by the long folding of the ducts with more than seven tUrns, bUt Differs by the pOre Of the atriUm at the pOsteriOr border of the median septum ( Figs 6 , 10 ) and by presenting eight turns of the ducts ( Figs 7 , 11 ).
