Diagnosis

Vein R1 setose only on proximal half. Sternite 5 shield- like with a small median convexity on the posterior margin. Surstylus with distal portion curved posteriorly ( Figure 1A View Figure 1 ). Pregonite with dorsal margin bearing a row of long and stout setae whichare sligthly swollen apically ( Figure 1C View Figure 1 ). Postgonal apodeme elongate ( Figure 1C View Figure 1 ). Vesical extension elongate and without bifurcation apically ( Figure 1D View Figure 1 ). Vesica with a row of toe-like projections on the apical margin ( Figure 1D View Figure 1 ). Etymology

This species is named in honour of the second author’s grandmother, Terezinha de Jesus Ferreira Costa, for her hospitalityduring fieldwork carriedout inthevillage of Calafate.

Description

Male. Body length: 4.63-5.10 mm (n = 4).

Head

Fronto-orbital and parafacial plates with goldenpruinosity, postocular strip light golden. Parafacial plate with a row of three fine setae along the lower part of the eye. Frontal vitta black; frontal row of four setae; one reclinate and two proclinate orbital setae. Gena andpostgena yellowish grey with black setae. Antenna black; first flagellomere aboutthree times as long as pedicel; arista long plumose in basal two thirds. Palpus and proboscis black.

Thorax

Chaetotaxy: acrostichals 0+1, dorsocentrals 2+3, intraalars 1+2, supra-alars 2+3, postpronotals 2, postalars 2, notopleurals 2, katepisternals 2, scutellum with marginal setae 2, apicals 0, discals 1. Wing hyaline, basicostabrown, vein R 1 setose onbasal half, vein R 4+5 setose dorsallyto crossvein r-m. Legs black; forefemur with several bristles along anterodorsal and anteroventral margins; foretibia with one anteroventral and one posterior seta; midfemur with two anterior and two anteroventral setae; midtibia with one anteroventral and two posterior setae; hindtibiawith two anterior, one anteroventral, and two posterodorsal setae.

Abdomen

Tergites dark brown, tergites 3 to 5 each with a band of silvery gray pruinosity anterolaterally. Sternites light brown with silvery gray pruinosity.

Terminalia. Sternite 5 shield-like, not cleft, with posterior margin sligthly sinuous and with a small median convexity, covered with long and stout setae and posteriorlly, above the convexity, with some short and spine-like setae ( Figure 1B View Figure 1 ). Syntergosternite 7+8, epandrium and cercus dark brown. Cercusshort (shorther than epandrium) and curved in profile, tapering distally, with pointed apex, covered with long setae, distal third without setae and setulae. Surstylus broad, sligthly narrowed at middle, with rounded apex curved anteriorly, covered with shortsetulae and with long setae mainly distally ( Figure 1A View Figure 1 ). Pregonite broad, shorther than postgonite, with dorsal margin bearing arow oflong and stout setae, which are slightly swollen apically ( Figure 1C View Figure 1 ). Postgonite claw-shaped with a long and stout seta on the anteriormargin ( Figure 1C View Figure 1 ). Postgonal apodeme elongate. Phallic tube elongate, narrow and tubular, slighly curved posteriorly ( Figure 1D View Figure 1 ). Vesica (highlighted in dark gray) enlarged and irregular ( Figure 1D View Figure 1 ); vesical extension elongatedand almost straight with rounded apex ( Figure 1D View Figure 1 ). In addition to the vesical extension, there are about five toe-like projections as about one-third or less longerof the total of the vesical extension length ( Figure 1D View Figure 1 ).

Female

Unknown.
