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

(Figs 42–50)

Material examined. Holotype, 1♀, China, Yunnan prov., Lijiang City , Yulong County, Shigu Town , 26°51'50.95"N, 99°57'20.01"E, 1876 m, 21.VII.2011, Tingjing LI, No. 1004095 ( CQNU)GoogleMaps  . Paratypes: 5♂, the same data as holotype, Nos. 1004096, 1004097, 1004098, 1004099, 10040100 ( CQNU)GoogleMaps  .

Diagnosis. This species is similar to E. (P.) nipanicus  by cephalic fovea (Fig. 48) larger, its width distinctly more than distance between posterior ocelli, T2 with distinct reflex apical lamella (Figs 30, 50), and S2 (Figs 27, 49) strongly convex. It differs from E. (P.) nipanicus  and other congeners by cephalic fovea (Fig. 48) with sparse FIGURES 42–50.

setae (denser in E. (P.) nipanicus  (Fig. 29)), T1 and T2 with strong punctures (Figs 42–43) (weaker in E. (P.) nipanicus  (Figs 21–22, 25–26)), in male apex of F11 bent backward reaching apex F7 (Fig. 47) (middle of F 8 in E. (P.) nipanicus  (Fig. 31)), and volsella of male genitalia slightly truncate apically (Fig. 44) (rounded apically in E. (P.) nipanicus  (Fig. 28)).

Description. Female. Body length 8.6 mm, forewing length 8.0 mm. Clypeus (Fig. 45) somewhat convex, moderately punctate, its length almost equal to width, ratio apical width: emargination depth = 0.27: 0.05, ratio total width: apical width = 1.32: 0.27; frons densely and strongly punctate and reticulate, punctures on vertex weaker than those on frons; frons and vertex with sparse setae; ocellar triangle usual; cephalic fovea comparatively larger (Fig. 48), its width distinctly more than distance between posterior ocelli, with irregular punctures and sparse setae.

Masosoma densely and strongly punctate and reticulate, punctures distinctly 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. 42). Anterior surface of pronotum shiny, with few punctures laterally, pronotal carinae completely and developed; mesoscutum and mesepisternum normal; scutellum slightly convex; metanotum with narrow horizontal and much longer vertical portions, posterior margin of horizontal surface with small denticles, in lower half of vertical surface shagreened; dorsal surface of propodeum behind metanotum with two teeth, posterior surface concave and with long and transverse rugae, irregular punctures, and median longitudinal carina; tegula with minute and sparse punctures, posteriorly distinctly curved inwards.

In dorsal view, T1 width 1.42 × its length and 0.90 × T2 width, with semitransparent apical lamella, densely punctate, punctures distinctly smaller than those on frons and mesosoma; T2 with distinct reflex lamella apically, punctures sparser and shallower than those of T1, apex with deeper and denser punctures than on other parts of T2; S2 (Fig. 49) strongly convex, with median longitudinal furrow basally, punctures sparser than those on T2; punctures of visible parts of T3–T4 and S3–S5 similar to those on T2; T5 and S5 with minute punctures.

Black. Following parts ferruginous: mandible, wide basal band and small medical spot of clypeus (Fig. 45), interantennal spot, scape ventrally, postocular spots, band of pronotum, small spot at the upper part of mesepisternum, tegula, parategula, metanotum except posterior apex ventrally, apex of femora to terminal tarsi, an apical band on each T1–T3 and S2–S4, and T4 medically (Fig. 42).

Male. Body length 8.0 mm, forewing length 7.7 mm. Sculpture, punctuation, setae and coloration similar to those of female except follows: whole clypeus yellow (Fig. 46); mid coxa, hind coxa internal side, apical band on S5–S6, and T5 medially ferruginous; clypeus weakly punctuate, with dense setae, ratio total width: apical width = 1.21: 0.37, ratio apical width: depth of emargination = 0.37: 0.08; in male apex of F11 bent backward reaching F7 (Fig. 47); in dorsal view, width of T1 1.57 × its length and 0.89 × T2 width; T2 with wider reflex apical lamella than in female (Fig. 50); male genitalia as in Fig. 44, apical tip of penis valve rounded, volsella with setae and slightly truncate apically, parallel spines elongate without setae; other characters same as those in female.

Distribution. China (Yunnan).

Etymology. The specific name similinipanicus  is a Latin adjective which refers to the similar species of E. (P.) nipanicus  .
