Sphegina (Asiosphegina) asciiformis is a species of syrphid fly in the family Syrphidae found in India. [2]
In female specimens, body length is 4.0 millimeters and wing length is 4.0 millimeters. The face is black; gena black, mouth edge red-brown with large triangular non-pollinose shiny area; occiput black; antenna brown to black; thorax dark brown to black; scutellum black, shiny, and semi-circular; pro- and mesoleg yellow; metafemur black and yellow biannulate, incrassate; metatibia black and yellow biannulate; metatarsus entirely black, basal tarsomere thick. A rather wide semi-circular area posterior of the lunula is non-pollinose and shiny. The arista is long. No male specimens are known. [2]
S. (A.) asciiformis' hyaline wing, oblique vein dm-cu, and short tergum II are similar to S. (A.) apicalis , S. (A.) farinosa , and S. (A.) nubicola , but differs by the entirely yellow pro- and mesolegs (in all others at least tarsomeres 4 and 5 of the pro- and mesotarsus are black) and by the entirely black abdomen. [2]
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 angustata is a species of hoverfly in the family Syrphidae found in Nepal. It's similar to S. abbreviata, though it's differentiated by having only a dorsal sublobe posteriorly on the male superior lobe instead of both dorsal and ventral, and by having the dorsal sublobe be long and pointed instead of apically short and truncate.
Sphegina (Asiosphegina) amplistylus is a species of hoverfly in the family Syrphidae found in the Philippines. It's similar to S. inflata, S. philippina, and S. spathigera.
Sphegina (Asiosphegina) atrimanus is a species of hoverfly in the family Syrphidae found in Vietnam.
Sphegina (Asiosphegina) bifida is a species of hoverfly in the family Syrphidae found in Malaysia. It's similar to S. (A.) inventum, though it's differentiated by having the male superior lobe on both sides longer than wide instead of wider than long.
Sphegina bracon is a species of hoverfly in the family Syrphidae found in Vietnam along with specimens of S. (A.) lucida, S. (A.) nigrotarsata, S. (A.) spenceri, S. (A.) verrucosa, and S. (A.) vietnamensis.
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 clavigera is a species of hoverfly in the family Syrphidae found in Vietnam. It's similar to S. crassispina and S. hauseri.
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 dentata is a species of hoverfly in the family Syrphidae found in Taiwan.
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) albolobata is a species of hoverfly in the genus Sphegina found in Vietnam. It's similar to S. (A.) licina, but differs by having the ventral lobe of both gonostyli narrower, apicodorsal part of the right superior lobe shorter, and the ventral part of the left superior lobe with more prominent anterior, medial, and posterior lobes.
Sphegina (Asiosphegina) atricolor 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 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 apicalis is a species of hoverfly in the family Syrphidae found in Taiwan.
Sphegina (Asiosphegina) bispinosa is a species of hoverfly in the family Syrphidae found in India, Nepal, and Bhutan. It's similar to S. (A.) hansoni, but easily differentiated by the strongly asymmetrical surstyli.
Sphegina guptai is a species of hoverfly in the family Syrphidae found in India. It's similar to S. elegans in general appearance and characters of the male genitalia. It differs from known Oriental species of Sphegina by the shiny black abdomen with widened terga III and IV. Only S. quadrisetae has a somewhat similar appearance.
Sphegina quadrisetae is a species of hoverfly in the family Syrphidae found in China. It's characterized by the long black pile posterior of the posteromedial corner of the eye, the scutellum with four long black setae at posterior margin, and the black and extremely strongly antero-ventrally projected face.
