Sphegina crinita

The name comes from Latin ‘crinita’, meaning ‘long-haired’, referring to the long setae on the male superior lobe.[1]

Like other species in its genus, S. crinita is small, slender, and wasp-like.[2] In male specimens, the body length is 6.4–6.9 millimeters (5.8–6.2 in females). The wings are 4.7–5.5 millimeters long (4.0–4.4 in females), hyaline, microtrichose (bare on baso-medial ¼ of cell and only weakly microtrichose on cell cup) with brownish stigma. The face is black, the ventral ⅓ to ½ yellow; concave with a very weakly developed frontal prominence and long pilose along the eye-margin. The gena is yellow to dark yellow; mouth edge dark brown to black with a large, subtriangular, non-pollinose shiny area; occiput black with light yellow pilose. Antenna with scape and pedicel dark brown with black setae dorsally; the basal flagellomere light-brown to yellow, oval to subrectangular; arista long and pilose, about three times as long as the basal flagellomere. Frons and vertex black, a subtriangular area posterior of the lunula non-pollinose and shiny. Thorax dark brown to black, postpronotum light yellow to brown-yellow; scutellum black, subrectangular, and shiny. The pro- and mesoleg are yellow with tarsomeres 3–5 black; metaleg with coxa black, trochanter yellow; femur black with basal ⅓ yellow, strongly incrassate; tibia black and yellow biannulate, with long and wide apicoventral dens; tarsus entirely black with a thick basal tarsomere. Females are similar to males except for normal sexual dimorphism.[1]
