Copidosoma recurvariae Sharkov

Figs 31–36

Copidosoma recurvariae Sharkov, 1988: 840 . Holotype ♀, Russia-Primor'ye Kray (ZISP, not examined).

Material examined. CHINA: 3♀ [No. E1308-01, E1308-02, E1308-03, on slides, NEFU], Xizang Autonomous Region (= Tibet), Linzhi City, Linzhi Park, 5.VII.2013, Hui-lin Han, Zhi-guang Wu, YPT.

Diagnosis. Female. Body mostly dark brown to black, with some metallic golden green reflection. Wings hyaline except for a small brown spot around marginal and stigmal veins of fore wing. Head in frontal view as in Fig. 31 , mandible with three sharp teeth and the middle tooth longest. Antenna ( Fig. 32 ) with scape long and slender, with reticulate sculpture; pedicel nearly as long as F1 and F2 combined, all funicular segments longer than broad, clava 3-segmented and concave ventrally, slightly shorter than scape, and nearly as long as 5 preceding funicular segments combined; sensorial part extending about 0.83× length of clava. Mesoscutum ( Fig. 33 ) with shallow polygonal-rounded reticulate sculpture, sculpture on scutellum similar to that of mesoscutum, but slightly smaller. Fore wing ( Fig. 34 ) with marginal vein about as long as postmarginal vein, both about 0.33× as long as stigmal vein. Linea calva closed by 2 lines of setae posteriorly. Mesotibial spur ( Fig. 35 ) 0.41× as long as mesotibia, nearly as long as two corresponding basal tarsi combined. Metasoma ( Fig. 36 ) 1.73× as long as mesosoma, slightly flattened laterally and prone to collapsing; ovipositor 0.95× as long as metasoma, 1.7× as long as mesotibia and distinctly exerted at apex of metasoma; exerted part of ovipositor about 0.25× as long as metasoma, 0.66× as long as mesotibia, and longer than mesotibial spur; third valvula about 0.33× as long as second valvifer.

Host. Unknown from China, but recorded as parasitoid of Recurvaria sp. ( Lepidoptera , Gelechiidae ) (Noyes 2017).

Distribution. China (Xizang) [new record], Russia (Primor'ye Kray) (Noyes 2017).

Comments. Our specimens agree quite well with the original description except for the relatively short portion exerted of the ovipositor. In the original description, the exerted part of ovipositor is described as 0.42–0.48× as long as metasoma (in dry specimens), whereas in our specimens it is only about 1/4 as long as the metasoma (slide mounted specimens). We consider this difference must have been caused by the conditions of specimens.

This species is most similar to C. remotum Sharkov due to having the antenna long and slender, clava 3- segmented and concave ventrally, mesoscutun and scuellum with polygonal-rounded reticulate sculpture, ovipositor distinctly exerted at apex of metasoma, and similar body coloration, but can be distinguished from the latter by the following combination of characters: ovipositor 1.7× as long as mesotibia (vs 0.98×), scape 6.25× as long as broad (vs 9.4×), basal and apical part of clava subequal in width, rounded at apex (vs clava gradually narrower distad, pointed at apex), clava with second suture distinctly oblique (vs nearly transverse).

This is the first record from outside the type locality.
