Summary:Rhinotorus umbrarum (Holmgren, 1857) Figs 14, 15 Trematopygus umbrarum (Holmgren, 1857): 180, lectotype examined. Trematopygus obliteratus (Holmgren, 1857): 183, lectotype examined. Diagnosis This species is distinguished from other species in the genus by the following characters: hind tibia black basally and apically and yellow centrally (Fig. 14); scutellum entirely black (Fig. 15 C–D); first and second metasomal tergites with weak transverse impressions (Fig. 15C). Type material examined Lectotype SWEDEN: ♀, Dalarna, leg. Boheman, NHRS-AVRE0000016, NHRS (lectotype of T. obliteratus). Other material examined FINLAND: 1 ♀, Oulu, Kainuu, Suomussalmi, leg.

Malaise, NHRS-HEVA000001987, NHRS. SWEDEN: 1 ♀, 1 Ƌ, Dalarna, leg. Boheman, NHRS; 1 ♀, Lappland, leg. Boheman, NHRS. Description Female Fore wing around 8–10 mm long. Antenna stout, around 0.8 times as long as fore wing and with 33–34 flagellomeres. Ratio of length of 1 st plus 2 nd flagellomeres to eye height 1.0. Scape as broad as long. Head not narrowed behind eyes, weakly shining. Lateral ocellus separated from eye margin by 1.6 times their widest diameter. Face transverse, 2 times as wide as high, shagreened and without punctures, (Fig. 15A). Clypeus 0.35 times as high as wide, distinctly separated from face by deep impression and projecting medially, its apical margin obtuse medially and impressed laterally. Clypeal fovea shallow. Malar space 0.8 times basal mandible width. Occipital carina complete. Mandible with upper tooth slightly longer than lower tooth. Mesoscutum weakly shining, finely granulate, with dense and uniformly strong punctation. Notaulus distinct. Mesopleuron finely granulate, weakly striated in upper part, shining and distinctly densely and strongly punctate. Metapleuron weakly shining, with rather dense but vague punctation in upper part.
