(Figs 3 A–C, 9A–D)
Type-material examined. Lectotype. Male: “ Bolivia - Guaqui \ 02. vi. 03 \ Titicaca See [green, printed label and partially handwritten, 03 = 1903]”; “ LECTOTYPE ♁ \ Coenosia \ albiseta \ Stein, 1911 \ Des. A. C. Pont 1999 [white printed label]” (SMT) (Fig. 9D). Paralectotypes: 3♁. Same data as Lectotype, 1♁ (ZMHU). Peru, Calca, 6. viii. 1903, 1♁ (SMT), Laristhal, 3–4000 m, 8. viii. 1903, 1♁ (SMT).
Additional material examined. Bolívia, Guaqui, Titicaca, 4-5000m, 02. vi. 1903, 2♁; Titicaca – Insel, 02. vi. 1903, 1♁; Sorata, 2300m, 18. xii. 1902, 1♁; La paz, 30. xi. 1902. Peru, Calca, 06. viii. 1903, 2♁; Cuzco, 3700–4000m, 17. vi. 1905, 1♁ (SMT).
Diagnosis. Stomopogon albiseta can be separated from other species by having the entire body covered with many white setae and first hind tarsomere flattened. In addition, it differs from S. hirtitibia, S. paranaensis sp. nov. and S. nigrisquama sp. nov. by the yellow tibiae, and from S. capribarba, S. argentina, S. inculta and S. boliviensis sp. nov. by the yellow postpedicel.
Redescription
Head (Fig. 9B). Frontal vitta, fronto-orbital plate, face, parafacial and gena dense silvery pruinose. Eye with small and sparse white cilia, distance between eyes 0.31 of maximum head-width. Antenna silvery pruinose, inserted above middle of eyes; postpedicel yellow, about 1.5 times pedicel length. Arista a little enlarged at base with hairs shorter than diameter of the base, apical third bare. 5 white frontal pairs of setae; 1 proclinate orbital seta; 1 upper orbital seta; ocellar seta well developed; postocellar seta divergent and with the same ocellar seta length; inner vertical seta parallel, similar in size with ocellar seta; outer vertical seta white, divergent similar in size with inner vertical setae. Proboscis shiny dark brown. Palpus brown and filiform.
Thorax (Fig. 9A, C). Acrostichal setae 4+4, hair-like; intra-alar setae 1+2, the second postsutural white and smaller than other; 2 notopleural setae, the second white; 6 anepisternal setae, 5 white and 1 black.
Legs (Fig. 9A). Black, only knees, tibiae and tarsi yellowish. Claws and pulvilli reduced. Fore femur with a complete pd row of black and long setae; p and pv complete rows of white and long setae. Fore tibia with 1 pv median short and white seta; 1 d and 1 pv apical seta. Mid femur with an a row with 6 medium-sized black setae; av and pv complete rows of long and white setae; 1 p seta on apical half. Mid tibia with 1 p median seta; apical seta on d, pv, v and av. Hind femur with an ad complete row of long setae; 2 anterior long setae on apical half; av complete row of long, white and black setae; 1 av and 1 pv seta on apical half; 1 d and 1 pd seta on apical half. Hind tibia on a to p with many long setae, the 6 ad, 3 d and 6 pd stronger than the others; 1 preapical setae on each ad, d, pd and av, all well developed.
Abdomen (Fig. 9C). Black, with many long white setae on all tergites. Sternite 5 U-shaped, covered with median to short setae (Fig. 3A).
Terminalia (Fig. 3 B–C). Cercus longer than wide, apically deep bifurcate, covered with sparse setae; hypandrium long tubular; phallapodeme similar length with hypandrium; pregonite and postgonite similar in length, postgonite bare.
Female. Not examined.
Distribution. Argentina (Tucumán), Bolivia (La Paz) and Peru (Calca, Cuzco).
