( Figs. 17–30 )

Diagnosis: Senopterina canina resembles S. flavifemoris by being more robust and having a more metallic shine, which is blue, never violet, while in S. brevipes the thorax is more slender, and with metallic lustre violet more inconspicuous; face straight (angulated in S. brevipes ); postpronotal lobe the same colour as thorax, never pale as in S. brevipes ; wing patterns darker, and cell br reaches crossvein dm-m vein, while in S. brevipes the wing pattern is lighter and br cell never reaches dm-m.

Body: ( Figs. 17–18 ) ground colour black, with metallic lustre blue, thorax robust. Measurement: body length: 4.5–11mm.

Head: ( Fig. 20–21 ) one orbital seta reclined to lateroclinate; one anterior orbital seta reduced; ocellar setae reduced and divergent; postocellar seta divergent; lunule light brown; face, in profile, straight, with a slight depression on the upper third; gena small, brownish yellow to dark brown; postgena brown; occiput yellow to brownish yellow; clypeal membrane brownish; labella dark brown, with a metallic lustre, covered by brownish yellow setae. Measurements: eye height 1.0– 1.9 mm; eye length 0.5–1.2 mm; head height 1.7–2.5 mm; head length 1.3–1.8 mm; postpedicel height 0.8–0.9 mm; postpedicel length 0.2; gena height 0.2–0.3 mm; frons posterior width 0.9–1.2 mm; frons anterior width 0.9–1.1 mm; frons length 0.7–1.1 mm; ocellar triangle length 0.1 mm.

Thorax: ( Fig. 18 ) brown to black, with metallic lustre blue, covered by whiteish yellow microtrichosity; scutellum bare, with two reclined setae; pleura with a white pollinosis. Measurements: thorax length 2.3–4.1 mm; thorax width 1.8–2.9 mm; thorax height 2.3–3.2 mm.

Legs: ( Fig. 17 ) brown covered by whiteish golden hairs, with metallic lustre blue to violet at fore femur; fore femur with a row of small setae at the dorsal surface; hind femur with a row of small setae, apical, at the dorsal surface; tibia with one black fascia at the posterodorsal surface.

Wings: ( Fig. 19 ) hyaline with fasciae brownish yellow to dark brown, dm-m in slightly “S” shaped; br fascia extending basally to dm-m; halter: black. Measurements: wing length 6.0– 10 mm; wing width 1.9–3.1 mm.

Abdomen: tergites brown to black, with metallic lustre blue, densely covered by whitish yellow hairs, except at synsternites 1+2; ♂: ( Figs. 26–26 ) epandrium, lateral view, anterior half straight inclined, posterior half straight, dorsal surface with fewer setae than in S. brevipes ; cerci straight; surstylus slightly longer than cerci; glans ovoid, length about 3x the width; terminal filaments long, longer than distiphallus; ♀: ( Figs. 27–30 ) spermathecae 2+1, ovoid, surface slightly corrugated, brownish yellow to brown; internal structure cylindric. Measurements: abdomen length 3.5–4.8mm; distiphallus length 2.8mm; glans length 0.37mm, glans width 0.14mm; terminal filaments length 3.5mm.

Distribution: Brazil (Goiás, Mato Grosso, and Mato Grosso do Sul) and Paraguay (Sapucay).

Etymology: caninus L. a. canine or of dogs. The holotype of this species was sampled as part of a project dedicated to ascertaining the necrophile flies that visit the corpses of dogs ( Rodrigues et al. 2019).

Biology: the specimens hosted at the ZUFMS was sampled from the carcass of a dog. The specimens hosted at the MZUSP came from the project SISBIOTA-Diptera ( Lamas et al. 2023), and were sampled using Malaise traps, Shannon traps, and Van Someren traps baited with sugar, banana, sardine, and beer. Most specimens were sampled from November to Mach and June to August—mid-spring to summer, and autumn to mid-winter, in the southern hemisphere.
