Diagnosis. Stomopogon garleppi is the only species that has the apical scutellar seta reduced, antenna with arista long and pubescent, the first abdominals tergites translucid yellow.

Redescription

Head ( Fig. 16B ). Frontal vitta, fronto-orbital plate, face, parafacial and gena dense silvery pruinose. Eye bare, distance between eyes 0.33 of maximum head-width. Antenna dark brown, antenna inserted on middle of eyes, pedicel yellowish, postpedicel about 2 times the pedicel length. 2 frontal setae, between than one reduced; proclinate orbital seta absent; 1 upper orbital seta; ocellar seta reduced, smaller than upper orbital seta; postocellar seta divergent, twice longer than ocellar seta; inner vertical seta parallel, twice longer than ocellar seta; outer vertical seta divergent subequal in length to inner vertical seta. Proboscis shiny dark brown. Palpus brown, filiform and a little enlarged at the apex.

Thorax ( Fig. 16C ). Acrostichal setae reduced, like covered setae; 6 anepisternal setae.

Hind femur many median setae on av to pd on median to apical half, 2 fine v.

Legs. Yellow, with knees and tibiae brownish. Claws and pulvilli reduced. Fore femur with a complete row of long and black pd setae. Fore tibia with 1 p median seta, 1 apical seta on d and pd. Mid femur with 2 p and 3 v setae on apical half. Mid tibia with seta, 1 a 2 pd, 1 p, 1 pv median setae; apical seta on d, pd, p, v and pv. Hind femur with many setae on av to pd on apical half. Hind tibia with many long setae on av to pd surfaces, the 1 d, 2 ad and 2 pd stronger than other; 1 preapical seta on d, pd and av, all well developed.

Abdomen. Grey, two first visible abdomen segments translucent yellow. Sternite 5 yellow.

Terminalia . Not examined.

Female. Very similar to male, but the setae on legs are more developed, and apex of the femora with black spot. Ovipositor with hypoproct rectangular and epiproct triangular.

Remarks. Pont (2001) placed this species in Stomopogon , but the author was not sure about the generic identity of the species. The apical scutellar seta reduced, antenna with arista long and pubescent and the first abdominals tergites translucid yellow present in S. garleppi are unique among Stomopogon species. In addition, these characters are also found in Pilispina Albuquerque (Coenosiini) . Based on these observations, it is possible that S. garleppi belongs to Pilispina , a hypothesis that can only be confirmed by a phylogenetic study.

Distribution. Bolivia (La Paz) and Peru (Huánuco).
