SPECIMENS EXAMINED. Holotype – ♂, Russia: Tuva Rep., 20 km SSW

Erzin, Tore-Khol’ Lake, 3.VII 2013 ( VL, MP) [ ZIN]. Paratype: ♂, Mongolia: Lun-

Ula 30 km WSW Dariganga, 1.VII 1971 (I. Kerzhner) [ PRC].

DIAGNOSIS. The most distinctive features of Elampus coloratus sp. n. are body coloration, shallow punctuation, and genital capsule. Male has red face, head dorsally and mesosoma green with extensive golden-red color on pronotum anteriorly, mesonotum, metanotum, mesopleuron and legs. Metasoma metallic red and sterna goldengreen. This coloration pattern was not observed in any other species so far.

Occasionally, male specimens of E. pyrosomus (Förster, 1853) may show a greenishgolden coloration. However, E. coloratus sp. n. can be separated from these specimens through the subtriangular shape of head, in frontal view (vs. transversally broadened in E. pyrosomus ) and genital capsule with gonocoxae differently shaped

( Fig. 2C vs. Fig. 2D ). Elampus sidus (Semenov, 1967) , from Iran, also shows a greenish-golden coloration, without a specific pattern, but can be recognized by large, robust habitus (Rosa et al. 2017x: Plate 290); face (in frontal view) mostly polished, impunctate; punctures on mesosoma dense, contiguous; metasomal lamella outstandingly broad. It is separated from other Asian species through shallow punctures on head, pronotum and mesoscutum, and subrectangular metanotal lamella with subparallel sides.

dorsal view; C – genital capsule; B – E. agnolii Rosa , sp. n., holotype, ♀; habitus, dorsal view; D – E. pyrosomus (Förster) , genital capsule. Scale bar = 1.0 mm for A, B and 0.5 mm

for C, D.

DESCRIPTION. Male. Body length 4.5–5.5 mm. Fore wing length 3.0– 3.5 mm.

OOL = 3.0 MOD; POL = 2.6 MOD; MS = 0.2 MOD; relative length of P: F1: F2:

F3 = 1: 2.2: 1.4: 1.0.

Head. Frons, vertex and face between scapal basin and eye with shallow, mediumsized punctures, 0.5 PD apart ( Fig. 1A ), even shallower on post-ocellar vertex; face relatively flat; scapal basin broad, medially polished in the upper fourth; medially and laterally rugulose ( Fig. 1A ); clypeus impunctate. Ocellar triangle isosceles.

Postocellar line deep and complete.

Mesosoma. Pronotum and mesoscutum with large (<1 MOD), shallow punctures

( Fig. 1C ). Punctures on mesoscutum increasing in size towards posterior margin;

notauli and parapsidal furrow complete. Mesoscutellum antero-medially impunctate,

the rest with deep, large (> 1 MOD), foveate punctures ( Fig. 1D ). Metascutellum with foveate-reticulate punctures and subrectangular lamella ( Fig. 1C ); lamella with parallel sides and large punctures (1–2 MOD), apically truncate ( Fig. 1C ); lamella,

in lateral view, slightly longer than mesoscutellum. Mesopleuron with foveate punctures and with scrobal carina reaching omaulus below its anterior protrusion

( Fig. 1B ). Fore femur basoventrally unmodified; tarsal claws with three teeth. Propodeal teeth acute, backwards directed ( Fig. 2A ). Forewing with Rs stub as long as pterostigma.

Metasoma. T1 with minute, evenly distributed punctures, 1–3 PD apart; T2 with larger punctures, with scattered minute punctures interspersed; punctuation on T3

coarser and rugulose towards apex; lateral margins shallowly sinuate before apical truncation; apical truncation forming half circle, its membrane indentation less than half truncation height ( Fig. 1F ).

Coloration. Head and mesosoma golden-green, red to golden-red on face,

pronotum anteriorly, mesonotum, metanotum, mesopleuron and legs; apex of metanotal lamella blackish; tegulae fully metallic green; tarsi yellowish. Metasoma metallic red, becoming purplish towards T3 apical snout; sterna green. Scape and pedicel metallic green, flagellum black. Wings hyaline, pale amber around pterostigma and radial sector.

Vestiture. Short (up to 1 MOD), whitish setae on head, mesosoma and laterally on metasoma.

Female. Unkown.

DISTRIBUTION. Russia (Tuva Rep.); Mongolia.

ETYMOLOGY. The epithet coloratus (masculine, adjective) refers to the multi-

colored body.
