Ctenochira magnusi Haraldseide, 2018: 27 [holotype female (Zoologische Staatssammlung, Munich, Germany) (not examined), Norway, Vindafjord, Oppsalsneset, 59.29479°N, 5.52589°E, 40 m, Malaise trap, VI.2016, coll. H. Haraldseide & E. Thorsen, CollHH1046].

Remarks.

This is the first record of C. magnusi from Russia. The male of this species is described here for the first time.

Variation.

A female from the Russian Far East possesses hind tarsal claws with teeth slightly denser and concentrated at the base of the claw (Fig. 20 ) than in material from Europe.

Description.

Male. Fore wing length 4.7-6.0 mm.

Antenna with 28-30 flagellomeres, about ten basal flagellomeres thicker than subsequent ones. Head smooth, shining. Face weakly convex in profile, distinctly and rather densely punctate. Frons with distinct moderately dense punctures. Vertex and temple finely and sparsely punctate. Clypeus convex in upper 0.3, flat in lower part, almost impunctate. Malar space and oral carina behind mandible about 0.5 times as long as basal mandibular width. Pronotum laterally with large polished area, with subparallel striation near collar and at lower corner. Epomia weak. Mesopleuron finely and sparsely punctate, with large polished speculum and almost impunctate below subtegular ridge and next to mesopleural fovea along mesepimeron. Mesoscutum with uniform small and dense punctures. Notaulus very weak or absent. Scutellum with sparse moderately large punctures and distinct lateral carina on its anterior 0.4-0.5. Tarsal claw of fore leg with 4 (or 5) small teeth in basal 0.8; claw of mid leg with 3 small teeth in basal half; claw of hind leg with 3 teeth in basal 0.4. Metasoma shining, impunctate, tergites 1 and 2 partly with longitudinal striation in posterior half, especially on postmedian transverse impressions; posterior half of tergite 3 and subsequent tergites smooth, with very fine punctures and pubescence.

Coloration. Antenna light brownish, scape and pedicel yellowish white ventrally, two or three basal flagellomeres brownish yellow ventrally. Head black; face, clypeus, malar space, palps, mandible (except for teeth) and part of gena from level of lower 0.3 of eye to mandible whitish. Mesosoma black; small spot in hind corner of pronotum whitish, tegula and plates at base of fore wing white. Fore and mid legs and hind coxa light reddish yellow, all trochanters yellow. Hind femur light brown, pale reddish in basal 0.2; hind tibia dull yellowish with apical 0.2 light brown. Metasomal tergites black, tergites 2 and 3 reddish, and tergite 4 in one specimen with small reddish marking at base. Sternites brown with yellow median longitudinal fold on sternites 1-5 (or 6).
