( Figs 18 A–D, 19A–D)

Type-material examined. Lectotype. Male: “ Chile \ 17. x. 02 \ Palca [green, printed label and partially handwritten, 02 = 1902]”; “ LECTOTYPE ♁ \ Coenosia \ hirtitibia \ Stein, 1911 \ Des. A. C. Pont 1999 [white printed label]” ( SMT) ( Fig. 18D ) . Paralectotypes 1♁ 6♀♀. Same data as lectotype , 1♀ ( SMT). Sorata , 2300m, v. 1903 , 1♁ 1♀ ( SMT); xii. 1903 , 2♀♀ ( SMT), 19. xii. 1902 , 1♀ ( SMT). Peru, Chanchamayo , 18. i. 1904 , 1♀ ( SMT) .

Additional material examined. Same data as lectotype, 1♀ ; 15. x. 02, 1♀; 20. x. 02, 1♀. Bolivia, La Paz, 30. xi. 02, 2♀♀ ; xi. 02, 1♀ ( SMT) .

Diagnosis. Stomopogon hirtitibia differs from all other species of the genus, but is similar to S. capribarba , in having fore coxa with several long white setae and scutum with two large brown vittae. Stomopogon hirtitibia can be separated from the latter by the black legs.

Redescription

Head ( Fig. 18B ). Frontal vitta dark brown; fronto-orbital plate, face, parafacial and gena dense silvery pruinose. Eye bare, distance between eyes 0.41 of maximum head-width. Antenna dark brown, inserted on middle of eyes. 3 Frontal setae; proclinate orbital seta absent; 1 upper orbital seta; ocellar seta well developed; postocellar seta divergent with same ocellar seta length and inner vertical seta parallel with 1.2 times the ocellar seta length; outer vertical seta divergent and shorter than inner vertical seta; postpedicel about 2.5 times pedicel length. Proboscis shiny dark brown. Palpus filiform, a little enlarged at the apex.

Thorax ( Fig. 18C ). Acrostichal setae 4+4; 5 anepisternal setae.

Legs ( Fig. 18A ). Dark brown. Claws and pulvilli reduced. Fore femur with a complete row of long pd setae. Fore tibia with 1 p fine seta on median to apical half; 1 d and pd apical seta. Mid femur with an a row with 7 seta on basal to median half, 1 v row of 5 long fine setae; 2 p setae on apical half. Mid tibia with 1 p median seta; apical seta on d, a, v and p. Hind femur on ad to pv with many setae. Hind tibia with many long fine setae on all surfaces.

Abdomen ( Fig. 18A ). Grey, with 4 pairs of central subquadrate spots on all tergites.

Terminalia . Not examined.

Female ( Figs 5 B–C and 19A–D). Similar to male, but the tibiae are yellow. Fore coxa with several long black setae. Femur and hind tibia without many long fine setae on all surfaces. Ovipositor with hypoproct and epiproct rectangular.

Distribution. Bolivia (La Paz) and Chile (Tarapacá).
