Stomopogon capribarba (Stein, 1911)

(Figs 4 A–C, 14A–D, 15A–D)

Type-material examined. Lectotype. Male: “ Bolivia \ 21. xii. 02 \ Sorata 2300m [green, printed label and partially handwritten, 02 = 1902]”; “ LECTOTYPE ♁ \ Coenosia \ capribarba \ Stein, 1911 \ Des.A. C. Pont 1999 [white printed label]” (SMT) (Fig. 14D) . Paralectotypes 5♁♁ 1♀. Same data as lectotype, 3♁♁ 1♀ (SMT), 2♁♁ (ZMHU) .

Additional material examined. Same data as lectotype, 10♁♁; 20. xii. 02, 1♁; 20. xii. 02, 1♀ (SMT) .

Diagnosis. S. capribarba can be separated from other species by mid and hind legs longer than foreleg and gena with several white dense very long setae beard-like. In addition, it differs from S. hirtitibia and S. paranaensis sp. nov. by the yellow tibiae and from S. albiseta and S. boliviensis by the yellow postpedicel.

Redescription

Head (Fig. 14B). Frontal vitta, light brown; fronto-orbital plate, face, parafacial and gena dense silvery pruinose. Eye bare, distance between eyes 0.46 of maximum head-width. Antenna dark brown, inserted on above middle of eyes, postpedicel dark brown, about 3 times pedicel length. 3 frontal setae, reduced; 1 proclinate orbital seta; 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, almost the same length as inner vertical seta. Proboscis shiny dark brown. Palpus brown and filiform.

Thorax (Fig. 14C). Two strong brown vittae running along dorsocentral lines. Acrostichal setae 4+4, hair-like; 5 anepisternal setae.

Legs (Fig. 14A). Black, with fore femur grey pruinose in basal half and yellowish on apical half; fore tibia grey pruinose; mid and hind legs yellowish. Fore coxa with several long white setae. Two first tarsomeres flattened. Claws and pulvilli reduced. Fore femur with a complete row of long and black pd setae. Fore tibia with 1 apical seta on d and pd. Mid femur with 2 p setae on apical half. Mid tibia with 2 p median setae; apical seta on d, a and v. Hind femur with complete row of long setae on ad; 2 a setae on apical half; an av row of 3 long setae on apical half; 2 d, 3 ad and 3 pd setae on apical half. Hind tibia with many long setae on all surfaces, the 3 ad, 1 d and 3 pd stronger than other (Fig. 14A); 1 preapical seta on ad, d, pd, av and v, all well developed.

Abdomen (Fig. 14C). 4 pairs of subquadrate central dark brown spots on tergites. Sternite 5 U-shaped, covered with many setae (Fig. 4A).

Terminalia (Fig. 4 B–C). Cercus longer than wide, apically shallow bifurcate; surstylus enlarged (lateral view); hypandrium long tubular; phallapodeme straight and smaller than hypandrium. Pregonite longer than postgonite, postgonite bare.

Female (15A–D). Similar to male, but without several white dense long setae on gena; the vitta along planes of dorsocentral setae is larger than male thorax vitta. Fore coxa without several long setae; fore tibia without a row of long setae on v to pv; first fore tarsus without a row of log setae on pd and row of seta beard-like on v. Hind tibia without many long setae on all surfaces. Two mid tarsi not flattened.

Distribution. Argentina (Tucumán) and Bolivia (La Paz).
