Senopterina brevipes ( Fabricius, 1805)

( Figs. 1–16 )

Dacus brevipes Fabricius, 1805 (original description); Senopterina brevipes Macquart, 1835 (new combination); Herina mexicana Macquart, 1844 (junior synonym); Herina splendens Macquart, 1846 (junior synonym); Herina angusta Walker, 1852 (junior synonym).

Diagnose: This species can be distinguished from congeners by slender habitus and the colour pattern of the body. It resembles S. canina sp. nov. and S. flavifemoris sp. nov. but differs from them by body violet, upper half of femora yellow and lower half violet. Senopterina canina and S. flavifemoris are blue, and the femora in S. canina are brown, and the fore femur in S. flavifemoris is brown and the mid and hind femora the proximal half is yellow, and distal half is brown. While S. macularis have three greenish longitudinal fasciae, these fasciae are absent in S. brevipes .

Body: ( Figs. 1–2 ) ground colour brown; metallic lustre violet. Measurements: body length 4.9–11 mm.

Head: ( Figs. 6–7 ) frons rectangular, longer than wider, anterior half brown posterior half yellowish brown; fronto-orbital plate with golden pruinescence; two orbital setae, reclined to laterocline, anterior regular, posterior reduced; postocellar setae reduced and divergent; face, yellowish, in profile, angulated 128°; facial ridge with dark fascia; parafacial with a golden pollinosis; gena yellow, small; postgena yellow, small; occiput brownish yellow; proboscis brown; labella brownish yellow. Measurements: eye height 1.1–1.9 mm; eye length 0.8–1.1 mm; head height 1.7–2.3 mm; head length 1.1–1.8 mm; postpedicel height 0.65–0.77 mm; postpedicel length 0.17–0.22 mm; gena height 0.18–0.28 mm; frons posterior width 0.8–0.9 mm; frons anterior width 0.6–0.8 mm; frons length 0.8– 0.9 mm; ocellar triangle length 0.2 mm.

Thorax: ( Figs. 1–2 ) brownish yellow, with metallic lustre violet; some specimens with two small fasciae yellowish brown at the prescutum; postpronotal lobe slightly lighter than thorax; postallar callus covered by a fine white hair; scutellum with one basal scutellar seta, one apical scutellar seta. Measurement: Thorax length 2.5–3.7 mm; Thorax width 1.5–2.2 mm; Thorax height 1.9–2.8 mm.

Legs: ( Fig. 2 ) brown, covered by whiteish setulae; femora with metallic lustre blue to violet, upper half yellowish, lower half brownish; anterior and posterior femur with a row of 5–8 setae on posterodorsal surface; tibia with a black fascia at the posterodorsal surface; tibiae and tarsomeres brownish yellow.

Wing: ( Fig. 5 ) hyaline with yellowish brown fasciae, narrowly extending along costa to M 1, and entire br brown; dm-m slightly “S” shaped, with membrane surrounding vein coloured brown; halter brownish black.

Measurements: wing length 5.0–9.0 mm; wing width 1.5–2.8 mm.

Abdomen: ( Fig. 2 ) same colour as thorax; tergites with sparse whitish setulae; ♂: ( Figs. 8–13 ) epandrium (in lateral view) anterior half concave, posterior half convex, longer than higher, dorsal surface with few setae; lateral surstylus longer than cerci; dorsal surface of cerci straight, with apex hollow; glans elongated, length 5x longer than width; terminal filament short, less than 2x the length of glans, with hooklike shape apically. ♀: ( Figs. 14– 16 ) spermathecae 2+1, weakly sclerotized, ovoid, smooth, internal structure cylindric with crest. Measurements: abdomen length 3.6–4.8mm; distiphallus length 3.8 mm; glans length 0.5 mm; glans width 0.1mm; terminal filament length 1mm.

Distribution: Bolivia, Brazil (Amazonas, Bahia, Pará, Rio de Janeiro, and Rio Grande do Sul. New records: Acre, Minas Gerais, Paraná, Pernambuco, Roraima, Santa Catarina, and São Paulo), Colombia, Guyana, Mexico, Paraguay, Peru, Suriname, and Trinidad and Tobago.
