Aspicera dianae Ros-Farré n. sp.

( Figs 1d , 31a & b )

Type material: (1♂ & 1♀). HOLOTYPE female ( CAS) 12/VII/1926, On flowers of Parsnip. VA ( USA, Locality unknown). E. Fallschurch col. ; PARATYPE 1♂ ( CNCI) 1960, Emerged from Metasyrphus vinelandi . J.R. Vockeroth col.

Diagnosis. Aspicera dianae belongs to the group of species with prominent interfoveal carina and lateral surface of pronotum without sharp transverse carinae. This species is similar to A. carinata having long and slender scutellar spine, but they can be distinged by the scutellum, which is flat in dorsal view in A. dianae and roof-shaped in A. carinata .

Description

Length. Male 2.9 mm.; female 2.9 mm.

Coloration. Head and mesosoma black. Metasoma black to dark brown. Scape and pedicellum dark brown, flagellomeres medium brown. Leg medium to light brown. Wing veins light brown.

Head. MALE. Frons coriaceous, with few weak points near lateral ocelli. Lateral frontal carinae slightly curved, sharp. Area between compound eye and lateral frontal carinae with scattered small transverse carinae. Gena in lateral view rounded, not expanded, coriaceous with noticeable transverse carinae. Vertex not incised, coriaceous, punctate, with small transverse carinae on central area. Ocelli weakly prominent. Occiput coriaceous, with thin longitudinal carinae behind ocelli. FEMALE. Lateral frontal carinae weak near lateral ocelli, straight, divergent. Area between compound eye and lateral frontal carinae with some small transverse carinae.

Antenna. MALE. Filiform. F1 clearly excavated. Antennal formula: 7(4.5): 4(4): 11(4.5): 9(4): 9.5(4): 9.5(4): 9(4.5): 9(4): 8.5(4): 8.5(4): 8(4): 8(4): 8(4): 12(4). FEMALE. Subclavate. F1 clearly excavate. Antennal formula: 9(5): 3(4): 8(5): 6.5(4): 7(4): 7(4): 7(4): 7(4): 7(4): 7(4): 7(4): 7(4): 15(4).

Mesosoma. MALE. Lateral surface of pronotum coriaceous. Subpronotal plate not projected, dorsal margin nearly glabrous. Scutum coriaceous with short transverse carinae. Lateral line incomplete, strongly noticeable on ventral half. Antero-admedian line sharp and prominent, reaching 1/3–1/2 scutum length, parallel; median ridge prominent. Notauli wide, smooth, with transverse carinae stronger near margins, median mesoscutal furrow smooth. Area between notauli sharply prominent in lateral view. Parascutal sulcus smooth, ending near anterior end of notauli, with scattered setae. Mesopleuron with oblique carinae and coriaceous on anterior 1/3, smooth posteriorly. Scutellum 1.1 times scutum length, clearly emarginate posteriorly. Scutellar foveae with effaced longitudinal carinae, deep and small compared to scutellar disc, scutellar pits shallow. Interfoveal carina very much prominent, noticeable in lateral view, continuing along scutellar disc until beginning of scutellar spine. Scutellar disc flat, coriaceous, with sharp rugose sculpture, clearly sloping towards basis of scutellar spine in lateral view. Scutellar spine 0.60 times length of scutellar disc, very thin, smooth, directed upwards in lateral view. FEMALE. Notauli with many fine transverse rugae. Scutellum as long as scutum. Interfoveal carina very much prominent, continuing along scutellar disc until first 1/3 of scutellar spine. Scutellar disc less rugose than in male. Scutellar spine 0.4 times length of scutellar disc.

Wing. MALE. Wing membrane hyaline. Radial cell 2.2 times longer than wide. Wing pubescence reduced. Marginal pubescence absent. R1 very short. R2 straight. Rs+M absent. FEMALE. Radial cell 2 times longer than wide. R1 short.

Derivatio nominis. Dedicated to Diana Ros i Farré, sister of the first author.

Biology. According to the labels this species emerged from Metasyrphus vinelandi .

Distribution. Nearctic: USA (Virginia).
