SPECIMENS EXAMINED. Holotype – ♀, Russia: Tuva Rep., W of Ujukskyi

Mountains, Kamennyi River Valley, 1000 m, 11–20.VII 2003 (collector unknown)

[ZIN].

DIAGNOSIS. Elampus agnolii sp. n. is similar to E. petri (Semenov) for the T3

apical rim, alike a sickle or boomerang, with narrow rim along margins. It can be easily separated from E. petri (see Rosa et al., 2017a: Plate 286) as follows: forefemur basoventrally with subrectangular carina ( Fig. 3C ) (vs. ecarinate in E. petri );

mesopleuron ventrally simple ( Fig. 3B ) (vs. mesopleuron ventrally with a distinct small denticle projecting outward); antenna simple (vs. unusually long and thick);

metanotal lamella subrectangular, with subtruncate apex (vs. metasomal lamella subtriangular and pointed). E. agnolii sp. n. is also similar to some specimens of E.

constrictus (Förster) for apical truncation of T3, but it is separated through forefemur basoventrally carinate ( Fig. 3C ) (vs. unmodified), mesopleuron with scrobal carina reaching omaulus below its anterior protrusion (see Paukkunen et al., 2015) ( Fig. 3C )

(vs. scrobal carina reaching omaulus at its anterior corner). It differs from E. panzeri

(Fabricius) for the shape of T3, with lateral margins almost straight before apical truncation ( Fig. 3F ) (vs. lateral margin of T3 distinctly sinuose before apical truncation); apical truncation of T3 falcate (vs. horseshoe-shaped). It differs from E.

foveatus (Mocsáry) through the falcate shape of apical rim (vs. apical truncation horseshoe-shaped with membrane differently shaped (see Paukkunen et al., 2015)).

Finally, it differs from E. pallasi (Semenov) through mesosoma punctuation and shape of the falcate apical truncation (vs. half-moon shaped).

DESCRIPTION. Female. Body length 6.1 mm. Fore wing length 4, 5 mm. OOL =

3.3 MOD; POL = 3.1 MOD; MS = 1 MOD; relative length of P: F1: F2: F3 = 1:

1.3: 0.8: 0.8.

dorso-lateral view; C – foreleg and mesopleuron, lateral view; D – metasoma, dorsal view; E

– metasoma, dorsal view; F – T3, postero-lateral view. Scale bar = 0.5 mm.

Head. Frons and vertex with shallow, small-medium punctures (0.2–0.5 MOD)

contiguous to confluent, with narrow interspaces, 0.1–0.5 PD apart ( Figs 2B , 3A );

face medially polished, with faint, transversal, semi-elliptical wrinkles around the median pit. Punctures on post-ocellar vertex shallower, smaller (0.2 MOD), broadly separated (1–4 PD apart), with impunctate interspaces. Ocellar triangle isosceles.

Postocellar line deep and complete.

Mesosoma. Pronotum largely polished, with small, sparse, mostly lacunose punctures ( Fig. 2B ). Mesoscutum with large punctures (up to 1 MOD) among notauli,

towards posterior margin; laterally with shallow, scattered, smaller punctures (1–4

PD apart). Notauli and parapsidal furrow complete. Mesoscutellum antero-medially impunctate, the rest with deep, large, foveate punctures ( Fig. 3D ). Metascutellum with foveate-reticulate punctures and subrectangular lamella; lamella considerably broad, as large as mesoscutellum disc, elongate; in lateral view, lamella longer than mesoscutellum; lamella with large punctures (1–2 MOD) and apically subtruncate

( Fig. 3D ). Mesopleuron with scrobal carina reaching omaulus below its anterior protrusion and with foveate-reticulate punctures ( Fig. 3C ). Fore femur basoventrally carinate; tarsal claws with three teeth.

Metasoma. T1 with tiny, minute punctures, 1–5 PD apart ( Fig. 2B ). T2 dorsally with tiny punctures clumped along anterior margin, becoming smaller and scattered on posterior half ( Fig. 3E ); laterally and posteriorly with few large, deep, lacunose punctures ( Fig. 3E ). T3 sharpened; punctuation denser than T1 and T2, laterally with rugulose, confluent punctures; lateral margins weakly sinuose and slightly concave before apical truncation; apical truncation sickle- or boomerang-like shaped, with narrow rim ( Fig. 3F ).

Coloration. Head and mesosoma metallic green to blue, occipital area dark blue,

mesoscutellum posteriorly and metanotal lamella blackish; tegulae dark brown,

with metallic reflection at base; tarsi yellowish. Metasoma metallic red, purplish towards the apical truncation of T3. Wings brownish, particularly around pterostigma. Scape and pedicel metallic green, flagellum black.

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

Male. Unkown.

DISTRIBUTION. Russia (Tuva Rep.).

ETYMOLOGY. The specific epithet agnolii (masculine name in genitive case)

is dedicated to Gian Luca Agnoli (Bologna, Italy), former owner of the holotype ,

who generously donated it to ZIN collection.
