Stomopogon boliviensis   sp. nov.

( Figs 2 View FIGURE 2 E–F, 3G–I, 6C–D, 12A–D, 13A–D)

Type-material examined. Holotype. Male. “ BOLIVIA, LA PAZ \ Prov. Murillo, Zona Sur \ Rio Abajo , 10-17.ii.2005 \ Jaime Rodríguez col. [white printed label]” “ Holotype ” [red, printed label] ( MNHN) ( Fig. 12D View FIGURE 12 )   . Paratypes 50♁♁ 15♀♀. Same label information, except: “ Paratype ” [green, printed label], 25♁♁ 7♀♀ ( MNHN), 20♁♁   4♀♀ ( DZUP), 5♁♁   4♀♀ ( MNRJ)   .

Diagnosis. S. boliviensis   sp. nov. differs from S. hirtitibia   and S. nigrisquama   sp. nov. by the yellow tibiae; from S. capribarba   , S. paranaensis   sp. nov. and S. albiseta   by the absence of several white long setae beard-like on gena; from S. inculta   by the fronto-orbital plate narrow and from S. argentina   sp. nov. by the frontal triangle short and gena well developed.

Etymology. The specific epithet, boliviensis   , a noun in apposition, refers to Bolivia, the country of the localitytype.


Holotype male. Length: Body: 2.3 mm. Wing: 2.5 mm.

Head ( Fig. 12B View FIGURE 12 ). Frontal vitta, fronto-orbital plate, face, parafacial and gena silvery pruinose. Eye with small and sparse white cilia, distance between eyes 0.38 of maximum head-width. Antenna black, inserted on above middle of eyes; postpedicel dark brown, about 1.5 times pedicel length. 4 frontal setae, the second one shorter than others; 1 proclinate orbital seta; 1 upper orbital seta; ocellar seta well developed; postocellar seta divergent with same ocellar seta length; inner vertical seta longer and outer vertical seta shorter than ocellar seta; upper orbital seta strong. Proboscis shiny dark brown. Palpus slender and dark brown and filiform.

Thorax ( Fig. 12C View FIGURE 12 ). Grey with light brown pruinose. 2 Postpronotal setae. Acrostichal setae 2+4; intra-alar setae 1+2, the anterior postsutural pair longer than posterior; 2 notopleural setae with almost the same length, without covered cilia. Scutellum with one long basal and one long apical pair of setae of similar length. Anepisternum covered by cilia and with a series of 5 setae.

Legs ( Fig. 12A View FIGURE 12 ). Black, femora grey pruinose, knees, tibia and tarsi yellowish. Claws and pulvilli reduced, pulvilli light brown. Fore femur with a complete pd and pv rows of setae. Fore tibia with 1 pv median seta; 1 d, p and pv preapical seta. Mid femur with av and pv series of long and fine setae; p with 1 preapical seta. Mid tibia with 1 p median seta, preapical seta on a, av, d, p, pd and v. Hind femur with many cilia on all surfaces, setae on p surface shorter than a surface. Hind tibia with many cilia on all surfaces, except p surface; d surface with longer setae; preapical seta on av and v.

Abdomen ( Fig. 12C View FIGURE 12 ). Black, light brown pruinose and with dark brown spots on all tergites. Sternite 5 Ushaped, covered with long setae on apical half ( Fig. 3G View FIGURE 3 ).

Terminalia   ( Figs 2 View FIGURE 2 E–F and 3H–I). Cercus longer than wide, apically shallow bifurcate; surstylus covered with setulae ( Fig. 2E View FIGURE 2 ); hypandrium long tubular; phallapodeme more or less the same diameter in all extension, curved on apical half and bigger than hypandrium ( Fig. 2E View FIGURE 2 ); pregonite similar to postgonite length; postgonite with 4 setulae ( Fig. 2F View FIGURE 2 ).

Female ( Fig. 6 View FIGURE 6 C–D, 13A–D). (n=15). Length: Body: 3.0-3.5 mm; Wing: 2.8-3.2 mm. Similar to male. Except: 5 dorsal vittae on thorax relatively conspicuous, apical scutellar setae half the size of the basal one, hind tibia with 3 ad and pd setae, 2 a and p supramedian, 2 a and p median and 2 a and p submedian setae; tibiae covered with shorter cilia; abdominal spots light brown. Tarsomeres light brown.

Distribution. Bolivia (La Paz).
