Figures 47–50

Holotype male, 15 km. southeast Barinitas , Barinas, Venezuela, II.26.1986, R. Miller & L. Stange ( FSCA).

Diagnosis. Pronotum with elongate white bristles laterally but without numerous elongate, erect bristles toward middle; midtibia slightly more swollen than foretibia; paramere in two continuous sections, section near gonarcus large, sub-rectangular, with scallop-like sculpture on surface, lower section twisted laterally, similar in shape to upper part, somewhat smaller, without projections or sculpture.

Holotype male. Length of body about 22 mm, forewing 21 mm, hindwing 22 mm. Coloration: face pale brown with dark brown band below and between antennal fosse, slightly emarginate ventrally at middle; pronotum and thorax as in Fig. 47 , mostly brown with narrow median light brown stripe on pronotum and scutelli; bristles on foreleg and midleg mostly white, those on hindleg mostly black. Chaetotaxy: pronotum with elongate white bristles at lateral margin at least subequal in length to elongate white setae on forecoxa, without numerous elongate erect bristles toward middle; midfemoral sense hair about as long as midfemur, equal in length to forefemoral sense hair; leg bristles moderately developed, those of hindtibia less than two times longer than tibial diameter; thoracic pleura with moderate elongate white setae. Structure: antenna with about 30 flagellomeres, basal three or four flagellomeres longer than wide, rest broader than wide; pronotum a little broader than long measured along midline;distal palpomere of labius weakly swollen; midtiibia slightly more swollen than foretibia; hind basitarsus about four times longer than median diameter, tibial spurs extend to tarsomere III; foreleg basitarsus about three times longer than median diameter, tibial spurs extending about to apex of tarsomere III; CuP + lA of forewing runs obliquely to hind margin along posterior fork of CuA at a point near origin of radial sector; male genitalia ( Fig. 50 ) with broad gonarcus, strongly arched, with large broad mediuncus which is about five times broader than long; paramere in two continuous sections, section near gonarcus large, sub-rectangular, with scallop-like sculpture on surface, lower section twisted laterally, similar in shape to upper part, somewhat smaller, without projections or sculpture. Female. Unknown.

Types. 2 males, February to May. VENEZUELA. Barinas: 15 km. southeast Barinitas, II.26.1986, R. Miller & L. Stange (2m, FSCA).

Discussion. This rarely collected species agrees with P. clavatus in having the midtibia slightly more swollen than the foretibia and this separates these two species from others in the group. The male genitalia are distinctive with the paramere in two continuous sections, section near gonarcus large, sub-rectangular, with scallop-like sculpture on surface, lower section twisted laterally, similar in shape to upper part, somewhat smaller, without projections or sculpture.

Etymology. Named for the Andes Mountains which lie to the west of the type locality.
