Diagnosis. Omalaspis norica is similar to O. villemantae n. sp., both having longitudinal carinae on each side of interfoveal line and the mesopleuron chagrinate. But in O. norica , the scutellar disc is almost as wide posteriorly than anteriorly, and the scutellar foveae have scarce and weak longitudinal carinae, while in O. villemantae , scutellar disc is narrower posteriorly than anteriorly, and the scutellar foveae have abundant and strong longitudinal carinae. Omalaspis norica can also be identified by the shape of the scutellar foveae, which are very oblique posteriorly; moreover, in this species, the frontal carinae are present with a furrow between them.

Redescription. Length. Male 2.9 to 3.6 mm.; Female 3.7 to 5.0 mm.

Coloration. FEMALE. Head and mesosoma black. Metanotum dark brown. Legs brown, coxa and trochanter can be black or brown. Antennae brown. Wing membrane slightly brownish to strongly yellowish, veins of wing dark to light brown. MALE. Antennae black. Coxa and trochanter black, remaining leg segments brown to light brown. Veins of wing brown.

Head. FEMALE. Frons coriaceous and slightly or strongly rugose. Frontal carinae present, sometimes weak, with deep furrow between them. Lateral frontal carinae conspicuous, space between them and compound eyes coriaceous with transverse carinae. Supratorular impression present but small. Ocelli prominent. Vertex in frontal view incised, in dorsal view coriaceous, with strong medial furrow. Vertex posterior weakly rugose. Occiput coriaceous. Genae sharply margined and expanded, with strong transverse carinae, which have coriaceous surface, space between carinae shiny. MALE. Lateral frontal carinae less impressed, with shallow furrow between them. Supratorular impression less noticeable than in female. Space between lateral frontal carinae and compound eyes with small transverse carinae.

Antenna. FEMALE. Filiform. Antennal formula: 5(4.5): 2(2): 7(2): 7(2): 6(2): 6(2): 6(2): 5.5(2): 5(2): 5(2): 5(2): 5(2): 9.5(2). MALE. Filiform. F1 strongly excavated. Antennal formula: 5(3): 2(2.5): 7(2): 6(2): 6(2): 6(2): 5(2): 5(2): 5(2): 4(2): 4(2): 4(2): 4(2): 6(2).

Mesosoma. FEMALE. Lateral surface of pronotum coriaceous, with very short and scarce transverse carinae dorsally, basally with conspicuous transverse carinae, central area coriaceous. Mesoscutum coriaceous, with small points. Parascutal sulcus shiny, sometimes with very fine transverse carinae. Median ridge complete, conspicuous, antero-admedian lines conspicuous, parallel or slightly convergent, reaching 1/3 mesoscutum length. Median mesoscutal furrow wide, reaching between 1/2 and 1/3 mesoscutum length, with numerous small transverse carinae inside, occasionally weakly alutaceous. Notauli wide posteriorly, narrow anteriorly, with abundant small transverse carinae inside. Mesosoma, in lateral view, slightly curved. Mesopleuron slightly sculptured anteriorly, smooth posteriorly. Scutellum 0.70 to 0.76 times scutum length. Interfoveal line reaching 1/2 to 1/3 scutellar disc length, sometimes going on until posterior margin of scutellum, as prominent as lateral margins of scutellum. Scutellar foveae oblique, with one or two oblique carinae, which are sometimes very difficult to see. Scutellar disc coriaceous, with one or two irregular longitudinal carinae, with furrow between lateral carina and lateral margin and flat between lateral carinae, sometimes with small transverse carinae at central area. Lateral scutellar margin straight on first 2/3, irregularly confluent posteriorly, posterior margin of scutellum truncate, wide. MALE. Lateral surface of pronotum with more conspicuous carinae on superior margin. Antero-admedian lines slightly confluent. Median mesoscutal sulcus wide, with numerous transverse carinae. Scutellum 0.70 to 0.73 times scutum length.

Wing. FEMALE. Radial cell 2.1 to 2.5 times longer than wide. R2 straight, curved near margin of wing. MALE. Radial cell 2.0 to 2.8 times longer than wide.

Distribution. Palaearctic: Germany ( Hartig, 1840), Austria ( Giraud, 1860), Switzerland ( Reinhard,1860), Hungary ( Kieffer, 1901), France ( Kieffer, 1902). First record from Sweden in this study.

Biology. Kieffer (1902: 297) mentioned that Carpenter obtained this species from larvae of a species of Syrphidae living on Eriosoma lanuginosum (Hartig, 1839) (= Schizoneura lanuginosa ) inside galls on elm and also that Pigeot obtained this species from pupae of Scaeva pyrastri (Linnaeus, 1758) (= Syrphus pyrastri ) (Dipt., Syrphidae ). Aphids in galls on Ulmus in Europe are commonly preyed upon by specialist Syrphids Heringia heringi (Zetterstedt, 1843) and Pipiza luteitarsis Zetterstedt, 1843 (and some generalists); these two species can be potential hosts of O. norica .

Comments. The type series of O. norica Giraud included two specimens, one is the lectotype and the other has been excluded because it does not belong to this species; although this specimen is truly an Omalaspis , it is impossible to determine the exact species due to its very bad state of conservation; then the first specimen is designed here as the lectotype of this species. Hedicke (1913: 146) described the male of Omalaspis norica Giraud ; after examining the material this specimen belongs not to Aspicerinae but to Figitinae . Tavaresia was synonymized with Omalaspis by Weld (1952) without examining the type material; after examining the type material of T. nigra we are sure that this species belongs to O. norica Giraud and that Tavaresia and Omalaspis are synonyms as Weld inferred.

Giraud misspelled the termination of specific name. We correct it here.
