Type material.

Lectotype, ♂ (ZISP) from Mongolia.

Additional material.

No material available for this study; reported from China by Lelej (2003).

Diagnosis.

Supra-antennal elevations 0.1-0.4 times as long as scapus and outer side of elevations oblique (Fig. 451); occipital carina lamelliform, wide; head black, but supra-antennal elevation anteriorly, two patches of clypeus, inner and (narrowly) outer orbita yellow; metanotum with lateral yellow patch; entire fore wing dark brown (Fig. 449); second metasomal sternite of female simple, only slightly convex (Fig. 449); second and third sternites of male with flattened and shiny posterior patch; second tergite and sternite with wide yellow band apically, and remainder of metasoma largely black (Fig. 450); length of body 14.5 mm.

Description

(translation of short redescription in Russian by Marshakov (1981); only males known). Male. Antenna with 23-25 segments, 10 th– 16th segments with tyloids; two spots on clypeus, a narrow band on inner and outer orbita of eyes, two spots on mesoscutum, [most of] postscutellum, band on first [mainly ventrally] and second [metasomal] segments, anterior and middle tarsi and tibiae yellow; [remainder of] legs light brown, antenna rusty yellow to light brown. Specimens from Amurskoj oblast have the scutellum marked with yellow, the wings are very slightly darkened and the background colour of the first and second [metasomal] segments is black (with brown-red hue in specimens from Mongolia); the head, the mesoscutum and the propodeum dorsally have large spots; the mesopleuron is finely densely punctate, with almost no interspaces between the punctures, matt; the frontal keels are like a “7”. The length of the body is 9-11 mm.

Biology.

Unknown.

Distribution.

China (Inner Mongolia); Russia; Mongolia; Korea ( Lelej 2003).

Notes.

Taeniogonalos flavocincta (Teranishi, 1929) was synonymized with Taeniogonalos mongolica by Marshakov (1981), but the holotype of Taeniogonalos flavocincta is not synonym with Taeniogonalos mongolica . The male holotype of Taeniogonalos flavocincta differs as follows: the frons, vertex and mesoscutum coarsely reticulate-punctate (moderately spaced punctate with distinct smooth interspaces in Taeniogonalos mongolica ; Fig. 451), the clypeus black (with pair of ivory patches; Fig. 451), the metanotum with only a medial ivory patch (with medial and pair of lateral patches; Fig. 450), the mesoscutum black anteriorly (with pair of ivory patches; Fig. 450), the second and third tergites densely and coarsely punctate, rather matt (largely smooth and strongly shiny; Fig. 450) and the posterior half of the fore wing subhyaline (infuscate; Fig. 449). From the translated redescription of Marshakov above it is clear that his series is mixed and consists of several species; the presence of Taeniogonalos mongolica in Inner Mongolia needs reconfirmation.
