Toxoneura gavryushini Ozerov & Krivosheina View in CoL sp. n. ( Figs 1, 3 View FIGURES 1–4 , 6 View FIGURES 5–7 , 8–10 View FIGURES 8–10 .)

MATERIAL. Holotype ♂, Vietnam: Lai Châu prov., Hoáng Liên N.P., 22.34997°N 103.76818°E, 1947 m, 19.IV.2012, D. Gavryushin ( ZMUM) GoogleMaps . Paratypes: same labels (6 ♂♂, 2 ♀♀, ZMUM) .

DESCRIPTION. Male, female. Length of body 3.3–4.2 mm. Length of wing 3.7–5.0 mm. Body, antennae and legs pale yellow; postcranium with black spot in centre ( Fig. 3 View FIGURES 1–4 ); male abdominal tergites 3 and 4 with indistinct blackish spots laterally; female tergites 3–5 with distinct black spots laterally, also tergite 7 and ovipositor black.

Head in profile oval, higher than long ( Fig. 1 View FIGURES 1–4 ). 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 narrowed to the apex, approximately 1.2 times as long as wide. Arista long, short haired on whole length; the longest setulae on arista shorter than basal diameter of arista.

Thorax. Scutum shiny, covered with black setulae, with the following paired setae: 1 postpronotal, 2 equal notopleurals, 1+1 supra-alars, 2 postalars, 1+3 dorsocentrals ( Fig. 3 View FIGURES 1–4 ). Scutellum shiny, with two pairs of setae approximately equal to each other. Pleural sclerites weakly greyish dusted. Anepisternum with several black hairs in posterior half and one strong seta near posterior margin. Katepisternum covered with rare black setulae, with one thin seta in upper posterior corner.

Legs. Fore femur with one long posteroventral seta near apex, one thin ventral seta near base, and 4–6 posterodorsal setae. Mid tibia with one ventral apical seta. Hind femur with one dorsal and one anterodorsal setae apically. Fore and hind tibiae, also mid femur without setae.

Wing with continuous longitudinal dark-brown band in upper quarter from base to tip of vein M 1 and dark-brown spot around crossvein dm-cu ( Fig. 6 View FIGURES 5–7 ).

Abdomen covered with black setulae, without noticeable setae. Male terminalia as in Figs 8–10 View FIGURES 8–10 ; subepandrial sclerite with 8–10 spines ( Fig. 8 View FIGURES 8–10 ).

SIMILARITY. The new species clearly differs from the other Oriental species Toxoneura striata in the structure of head and wing pattern (see key to species below). The wing pattern of T. gavryushini is very similar to that of Palaearctic Toxoneura czurkini Ozerov, 1993 (compare Figs 6 and 5 View FIGURES 5–7 ), but the latter species has a large black spot on postcranium ( Fig. 4 View FIGURES 1–4 ) and scutum with two blackish bands along dorsocentral lines ( Fig. 4 View FIGURES 1–4 ).

BIOLOGY. The specimens were collected in mountain forest by sweeping.

ETYMOLOGY. The new species is named after the collector, Dmitri I. Gavryushin.
