Euodynerus (Pareuodynerus) deqinensis Ma, Chen  , & Li, sp. nov.

(Figs 15–20)

Material examined. Holotype, 1♂, China, Yunnan Prov., Diqing Zang Autonomous Prefecture , Deqin County, Foshan Town , 28°43'16.44"N, 98°41'06.27"E, 2186 m, 22.VII.2014, Tingjing Li, No. 1004081 ( CQNU)GoogleMaps  . Paratypes, 4♂, the same data as holotype, Nos. 1004082, 1004083, 1004084, 1004085 ( CQNU)GoogleMaps  .

Diagnosis. This species is similar to E. (P.) nipanicus  by clypeus (Fig. 17) width of male somewhat less than length, T2 with reflex apical lamella (Figs 18, 30), and punctures on apex of T2 more deeper and denser than those on other parts. It differs from E. (P.) nipanicus  and other congeners by tegula almost impunctate (Fig. 15), S2 (Fig. 20) moderately convex (strongly convex in E. (P.) nipanicus  (Fig. 27)), with distinct median longitudinal furrow basally (less distinct in E. (P.) nipanicus  (Fig. 27)), punctures on metasomal terga (Fig. 15) strong (weaker in E. (P.) nipanicus  (Figs 22, 26)), and apex of F11 bent backward far beyond middle of F8 (Fig. 19) (reaching middle of F 8 in E. (P.) nipanicus  (Fig. 31)).

Description. Male. Body length 8.6 mm, forewing length 8.0 mm. Clypeus (Fig. 17) somewhat convex medially, with minute punctures and short setae, width 0.95 × length, ratio apical width: emargination depth = 0.40: 0.07, ratio total width: apical width = 1.18: 0.40; frons densely and strongly punctate and reticulate, punctures on vertex somewhat weaker than those on frons; frons and vertex with dense setae; ocellar triangle usual; apex of F11 bent backward far beyond middle of F8 (Fig. 19).

Masosoma densely and strongly punctate and reticulate, punctures somewhat larger than those on the head; punctures on propodeum distinctly larger than those on pronotum, mesoscutum, mesepisternum, and scutellum; punctures on metanotum somewhat smaller than those on other parts of the masosoma (Fig. 15). Anterior surface of pronotum shiny, with few punctures laterally, pronotal carinae completely and well developed; mesoscutum and mesepisternum normal; scutellum slightly convex; metanotum with narrow horizontal and much longer vertical one, posterior margin of horizontal surface with small denticles, in lower half of vertical surface with microscopic punctures; dorsal surface of propodeum behind metanotum with two teeth, posterior surface concave with long and transverse rugae, irregular punctures, and median longitudinal carina; tegula almost impunctate, posteriorly distinctly curved inwards.

In dorsal view, T1 width 1.68 × its length and 0.90 × T2 width, with semitransparent apical lamella, weakly punctate, punctures distinctly smaller than those on frons and mesosoma; T2 with distinct reflex lamella apically, punctures sparser and smaller than those of T1, apex with deeper and denser punctures than on other parts of T2; S2 (Fig. 20) moderately convex, with distinct median longitudinal furrow basally, sparsely punctate, punctures from base to apex more denser; visible parts of T3–T5 distinctly punctate, apex of T6–T7 and S3–S5 weakly punctate, and other visible parts almost impunctate. Male genitalia as in Fig. 16, apical tip of penis valve rounded, volsella with setae, parallel spines elongate without setae.

Black; following spots yellow: mandible basally, clypeus (Fig. 17), scape largely except a linear black spot on dorsal surface, and inter-antennal; post-ocular spots, band on pronotum, spot at the upper part of mesepisternum, tegula, parategula, metanotum except posterior apex ventrally, blurred spot of propodeal dorsal surface, coxae, apex of femora to terminal tarsi, and an apical band on each metasomal terga (Fig. 15) and sterna orange yellow.

Female. Unknown.

Distribution. China (Yunnan).

Etymology. The specific name deqinensis  is the Latin adjective and refers to the region where the type specimens were collected.
