MATERIAL. Holotype male, labeled “Примор. кр./р. Биамо 14.VIII.1976 Н. Синиченкова” [ Russia: Primorsky Krai, Biamo River [now = Bol’shaya Svetlovodnaya River ] (ca. 46.392ºN, 137.086ºE), 14.VIII.1976, N. Sinichenkova] ( ZMUM). GoogleMaps
DESCRIPTION. Male ( Fig. 3 View Fig ). Length of body ca. 3.0 mm. Length of wing 3.2 mm. Body in ground colour, antennae and legs pale yellow; postcranium black in upper third ( Fig. 4 View Fig ); scutum with large black spot ( Fig. 4 View Fig ); mediotergite and abdominal tergites 1–4 mostly blackish.
Head in profile about as high as wide. Length of frons slightly more than its width. Height of gena below eye is about 1/3 of vertical diameter of eye. Head with 1 orbital, 1 ocellar, 1 outer vertical, and 1 inner vertical setae; postocellar absent. Gena and postcranium with thin black setulae. Postpedicel approximately 1.2 times as long as wide. Arista long, short haired on whole length; the longest setulae on arista equal to basal diameter of arista.
Thorax. Scutum shiny, covered with short yellow hairs, with the following paired setae: 1 notopleural (posterior), 1 postalar, 1 postsutural dorsocentral ( Fig. 4 View Fig ). Scutellum shiny, with two pairs of setae approximately equal to each other. Pleural sclerites subshining.
Legs covered with yellow hairs, without striking setae.
Wing surface transparent with two dark areas: along crossvein dm-cu and at apex ( Fig. 3 View Fig ). Veins very short setulose only.
Abdomen covered with yellow setulae, without noticeable setae.
SIMILARITY. The new species is more similar to Toxoneura ambusta (Meigen, 1826) and Toxoneura shatalkini (Ozerov, 1993) in wing pattern ( Fig. 3 View Fig ), but clearly differs from both species by the absence of supra-alar seta, only one notopleural (posterior) and one postalar setae. T. ambusta and T. shatalkini have supra-alar seta, 2 notopleural and 2 postalar setae. All the three species differ from each other in the pattern on the scutum ( Figs 4–6 View Fig ): scutum of T. ambusta

yellow with four black stripes ( Fig. 5 View Fig ), scutum of T. shatalkini has large shiny black spot ( Fig. 6 View Fig ), and T. biamoensis with spot as in Fig. 4 View Fig . Some European dipterists believe that the drawing on the scutum of T. ambusta and T. shatalkini is a color variation [https://diptera.info/forum/viewthread. php?thread_id=92819].
