( Figs 27–45 View FIGURES 27–33 View FIGURES 34–45 )

Etymology. The species epithet is in honor of Dr. Stephen D. Gaimari, who has contributed substantially to the study of Diptera .

Description. Holotype ♂. Body length 4.98 mm.

Diagnosis. Palpus mainly dark yellow, brown medially. Alar membrane brown infuscated, denser on cells c, r1 and r2+3. Tergite 6 about 4X shorter than syntergosternite 7+8, longer laterally. Cercus with a small pointed projection in the tip.

Head ( Figs 27–29 View FIGURES 27–33 ). Frontal pruinosity velvety dark brown, with distinct dorsal vitta projecting laterally to ocellar triangle reaching vertex area ( Fig. 28 View FIGURES 27–33 ). Height 1.5X the length; width 1.3X the height. Frons 1.9X wider than long. Fronto-orbital plate with gray-yellowish pruinosity in frontal view ( Fig. 28 View FIGURES 27–33 ). Antenna with arista brownish on basal half ( Fig. 27 View FIGURES 27–33 ). Genal groove area brown, large, bare, with dark brown spot, larger near eye margin; gena predominantly gray pruinose; postgena with dark gray to brown pruinosity ( Fig. 29 View FIGURES 27–33 ). Palpus mainly dark yellow, brown medially.

Thorax ( Fig. 30 View FIGURES 27–33 ). Mesonotum dark brown to black; when seen from dorsal view and with dorsal, lateral and anterior incident light with large medial gray stripe intermixed with brown stripes, reaching scutellum. Scutellum dark brown to black with gray pruinosity. Legs ( Fig. 27 View FIGURES 27–33 ). Coxae, femora and tibiae brown to dark brown. Tarsi light brown. Wing ( Fig. 31 View FIGURES 27–33 ). Slightly light brown infuscated along anterior (costal) half. Length 4.3 mm, width 1.4 mm, 3X longer than wide.

Abdomen ( Fig. 33 View FIGURES 27–33 ). Male terminalia. Tergite 6 thin, about 4X shorter than syntergosternite 7+8, longer laterally ( Figs 34–35 View FIGURES 34–45 ). Epandrium with scattered setae on posterior half; posterior margin with medial reentrance ( Fig. 35 View FIGURES 34–45 ). Cercus almost as wide as long, longer than epandrium, somewhat horizontally directed with a small pointed projection in the tip ( Figs 34–37 View FIGURES 34–45 ). Hypandrium 2.4X longer than epandrium ( Fig. 34 View FIGURES 34–45 ). Phallapodeme 1.6X longer than hypandrium ( Figs 34–35 View FIGURES 34–45 ). Basiphallus as long as distiphallus ( Figs 34, 36 View FIGURES 34–45 ). Distiphallus subrectangular in ventral view, with two small projections basally ( Fig. 39 View FIGURES 34–45 ). In ventral view, pregonite with distal mesial keel pointed and bifid when seen in ventral view ( Figs 38–39 View FIGURES 34–45 ); postgonite wide, slightly bilobate ( Figs 36, 39 View FIGURES 34–45 ). Gonocoxal apodemes upward directed, somewhat sinuous in lateral view ( Fig. 36 View FIGURES 34–45 ), distinctly fused and with a small dorsal lobe when seen from posterior view ( Fig. 40 View FIGURES 34–45 ).

Female similar to male, except wing distinctly darker, dark brown on cells c, r1 and r2+3 ( Fig. 32 View FIGURES 27–33 ). Female (n = 2). Body length 4.36−4.41, mean 4.38 mm; wing length 3.53−3.77, mean 3.65 mm; wing width 1.06−1.36, mean 1.21 mm. Terminalia ( Figs 41–45 View FIGURES 34–45 ). Sternite 6 with small sclerite on anterior margin, roughly diamond in shape, bare; and two sublateral small sclerites on posterior margin, strongly sclerotized ( Fig. 42 View FIGURES 34–45 ). Tergite 7 weakly fused with the sternite 7 dorsally with short and sparse setae on posterior ¾, which are long and thin distally. Epiproct and hypoproct small, plate-like. Cerci brown setose, separated, elongated and thin ( Fig. 44 View FIGURES 34–45 ).
