Apex of the posterolateral angle narrower than base and ventrally curved in some specimens ( Fig. 5J–L ). Parameres subparallel to posterolateral angles, attaining or slightly surpassing the apex of segment X, spatular, base cylindrical and apex expanded and flattened terminating with an apical tooth-like projection on lateral margin, sometimes laterally sinuous; setae on anterolateral portion of parameres, directed to posterolateral angles ( Figs. 5J–L , 6C ). Segment X subcylindrical, basal portion membranous forming a concave line at the limit with the sclerotized area ( Fig. 5J–L ).

Genitalia. Gonocoxites VIII oval, longer than wide, covering the base of laterotergites IX, margins slightly sinuous, posterior margin over gonocoxites IX convex. Laterotergites IX digitiform, directed diagonally to apex ( Fig. 8D ). Inner arms of gonocoxites IX widening towards apex, more sclerotized than disc. Vesicular area of ductus receptaculi about six times longer than the combined length of pars intermedialis and capsula seminalis ( Fig. 9C ). Distribution: Costa Rica , Panama and Ecuador .
