Description

Size: Body length 5.4 to 6.5 mm; wing length 4.1 to 4.9 mm

Description: Head: Black; face concave with lower face projecting forwards along the oral margin, pale pilose along oral margin but bare above and shiny except with triangular silver area of pollinosity between antenna and margin of eye; gena pale pilose, shiny; frontal triangle shiny, pale pilose; vertex black, bare except ocellar triangle black pilose; occiput pale pilose with some short black setae on dorsal ¼ and shiny except for some white pollinosity along lower eye margin; antenna brown or brown and orange, scape and pedicel with short, black pile, pedicel about as long as scape, postpedicel elongate, about three times as long as wide, with minute sensory pit on inner surface, arista bare; eye bare, with no coloured markings and broadly holoptic.

Thorax: Mesonotum dominantly metallic blue, sometimes with a mix of green, bronze and or purple colouration, with differently coloured dorsomedial stripes and pale pilose; scutellum metallic blue, pale pilose; subscutellar fringe absent; postpronotum metallic blue, pale pilose; postalar callus metallic blue, pale pilose and shiny; pleuron metallic blue and shiny; anterior anepisternum, katepimeron and meron bare; posterior anepisternum and anepimeron pale pilose; katepisternum discontinuously pale pilose; metasternum black and bare; coxa brown, shiny and pale pilose; femora brown except apex yellow, pale pilose, except metafemur with black setae ventrally and shiny; tibia brown, except yellow on anterior third and at posterior joint, pale pilose and shiny; tarsomeres brown except 1st tarsomere yellow and black pilose ventrally; wing entirely densely microtrichose; halter yellow; calypter white.

Abdomen: Black; tergites 1-4 dull brown medially and shining laterally, black pilose medially and pale pilose laterally; sternites shining and pale pilose; postabdomen shining and pale pilose.

Genitalia: Epandrium subquadrate, longer than wide, narrows slightly dorsally; cercus with laterally compressed, subtriangular sclerotised outer portion covered in long pile and membranous inner portion; surstylus long, fingerlike, but curving inwards and with rounded apex, with conspicuous long pile on outer surface and inner surface; subepandrial sclerite broad, with narrow membranous v-shaped medial section; hypandrium with patch of macrosetae posterior to postgonite, ejaculatory apodeme conical; phallapodeme short and straight; postgonite long antler-like structure projecting ventrally, terminating in three spines; distiphallus elongated apically, narrow, projecting upwards between surstyli, with sharp pointed apex and long ventral tooth curving anteriorly; phallus simple tube within hypandrium.

Female: Same as male except for usual sexual dimorphism.

See Fig. 12.

Diagnosis

Lacks eye markings typical of most Orthonevra species. Legs bi-coloured and postpedicel longer than scape plus pedicel combined.

Etymology

This species is named after Frank Fee, who collected all known specimens of the species. Frank was a prolific syrphid collector, returning to the same sites year after year in an effort to slowly build series around rare or new species.

Distribution

All known specimens were collected from Scott Bog in New Hampshire.

Ecology

All specimens of this rare species were collected in early to mid-June at a single location. Specimens were collected on Cornus sericea , Fragaria and Taraxacum .

Taxon discussion

Attempts to sequence this species failed. It is clearly closely related to the other Orthonevra species that lack eye markings. Orthonevra robust a also lacks eye markings but has entirely black legs and postpedicel shorter than scape plus pedicel combined.

Common Name

The common name given to the species by Skevington et al. (2019) is Fee's Mucksucker.
