Sphegina (Asiosphegina) cerina is a species of hoverfly in the family Syrphidae found in Kambaiti Pass, Myanmar, a montane forest with swampy areas and streams located 2000 meters above sea level. [1]
The name comes from Latin 'cerina', meaning 'wax-coloured or yellowish', referring to the fly's yellowish coloration.
Like other species in its genus, S. (A.) cerina is small, slender, and wasp-like. It bears a slight resemblance to species such as S. (A.) cultrigera , S. (A.) ensifera , S. (A.) siculifera , S. (A.) parvula , S. (A.) sinesmila , S. (A.) minuta , and S. (A.) pusilla , but is easily differentiated by its yellow gena and yellow scutellum, as well as the long S-shaped surstylus and the claw-like, apically tapering superior lobe. In male specimens, the body length is 6.2 millimeters. The wings are 6.0 millimeters long, hyaline with yellowish stigma. The face is yellow and moderately concave with a weakly developed frontal prominence. The antenna are yellow, the basal flagellomere 1.5 times longer than broad, and the arista is yellowish and pilose. The surstyli are nearly symmetrical and the superior lobes are slightly asymmetrical. Females are much the same except for normal sexual dimorphism; body length is 5.9 to 6.8 millimeters and wing length is 5.6 to 6.5 millimeters. [1]
Sphegina abbreviata is a species of hoverfly in the family Syrphidae found in Nepal. Like other species in its genus, S. abbreviata is small, slender, and usually found in and around woodlands. It's similar to S. angustata, though it's differentiated by having both dorsal and ventral sublobes posteriorly on male superior lobe instead of just a dorsal one, and by having the dorsal sublobes be apically short and truncate instead of long and pointed.
Sphegina (Asiosphegina) brevipilus is a species of hoverfly in the family Syrphidae found in China. It's similar to both S. (A.) plautus and S. (A.) simplex; it and S. (A.) plautus are the only known species with a sclerite between the bases of surstyli as well as posteriorly from the cerci.
Sphegina collicola is a species of hoverfly found in Malaysia.
Sphegina crinita is a species of hoverfly in the family Syrphidae found in Malaysia and Indonesia. It's easily identified by its superior lobes, the left side one being pushed over the medial line of the hypandrium to the right side so that the right side one seems bilobed. Otherwise, the genitalia are nearly identical to those in S. fimbriata.
Sphegina uncinata is a species of hoverfly in the family Syrphidae found in Myanmar. It's easily identified by a straight dorsal line of frontal prominence that ends just before the ocellar triangle, a strongly projecting mouth edge, and a vibrissal angle more strongly protruding than the frontal prominence.
Sphegina (Asiosphegina) achaeta is a species of hoverfly in the family Syrphidae found in Myanmar. It's easily identified by the weak setae on abdominal tergite I. It's similar in appearance to S. adusta but easily differentiated upon closer examination. The male genitalia are similar to S. pollex and S. culex, though it can be distinguished by having an acute posterodorsal corner of the superior lobe and a broader surstylus; it differs further from S. pollex by lacking a sub-basal dorsal thumb-like lobe. The arrangement of bristles on tergite I is similar to S. japonica.
Sphegina (Asiosphegina) adusta is a species of hoverfly in the family Syrphidae found in Myanmar. It's easily identified by its large size, left side surstylus with a number of unusual lobes, and general dark-brown coloration. It's similar to S. atricolor and S. furva, but unlike these species it lacks a transverse crest at the base of the lobe located sinistrolaterally at the posterior margin of male sternite IV.
Sphegina (Asiosphegina) atricolor is a species of hoverfly in the family Syrphidae found in Myanmar.
Sphegina (Asiosphegina) bidens is a species of hoverfly in the family Syrphidae found in Myanmar.
Sphegina (Asiosphegina) bilobata is a species of hoverfly in the family Syrphidae found in Myanmar. It's set apart from other species by its general pale yellowish color with three black longitudinal stripes on the scutum combined with the infuscated pattern at cross veins on the wing. The male sternite IV with its symmetrical pair of short spinose lobes posteriorly is quite distinct.
Sphegina (Asiosphegina) carinata is a species of hoverfly in the family Syrphidae found in Kambaiti Pass, Myanmar, a montane forest with swampy areas and streams located 2000 meters above sea level.
Sphegina crassispina is a species of hoverfly in the family Syrphidae found in Kambaiti Pass, Myanmar, a montane forest with swampy areas and streams located 2000 meters above sea level. A specimen was found in China that fits the description of S. crassispina save for the more extensively shiny frons and the slightly more protruding frontal prominence.
Sphegina crucivena is a species of hoverfly in the family Syrphidae found in Kambaiti Pass, Myanmar, a montane forest with swampy areas and streams located 2000 meters above sea level.
Sphegina culex is a species of hoverfly in the family Syrphidae found in Kambaiti Pass, Myanmar, a montane forest with swampy areas and streams located 2000 meters above sea level.
Sphegina cultrigera is a species of hoverfly in the family Syrphidae found in Kambaiti Pass, Myanmar, a montane forest with swampy areas and streams located 2000 meters above sea level.
Sphegina index is a species of hoverfly in the family Syrphidae.
Sphegina malaisei is a species of hoverfly in the family Syrphidae.
Sphegina pollex is a species of hoverfly in the family Syrphidae.
Sphegina siculifera is a species of hoverfly in the family Syrphidae.
Sphegina kumaoniensis is a species of hoverfly in the family Syrphidae found in India, Thailand, and northeast Myanmar. It's characterized by a convex dorsal line of frontal prominence that ends clearly before the ocellar triangle as well as a mouthedge less strongly projecting, vibrissal angle less protruding or equal with the frontal prominence.
