19. Pediobius erionotae Kerrich, 1973

(Fig. 18)

Pediobius erionotae Kerrich, 1973: 178 –179; ♀. Holotype ♀, BMNH, not examined.

Diagnosis. Vertex with setae long, almost smooth, only the area circled by three ocelli weakly reticulate (Fig. 18 a). Notauli distinct, continuing as inner margins of notaular depressions. Scutellum about as long as broad, longitudinally reticulate (slightly striate) at sides, smooth and polished in the median half (Fig. 18 a); but the smooth median band narrower for male (Fig. 18 d). Propodeum with a fine median carina (Fig. 18 a).

Material examined. CHINA, Yunnan: 4♀ 2♂, Lincang, X.1981, coll. Ding-Xi Liao, ex. Braconidae sp. Determined specimens compared (ANIC) : 1♀, JAVA: Yogyakarta, 02.VI. 1974, coll. Eddy Mahrub, ex. the egg of Erionota thrax (L.) (Lepidoptea: Hesperiidae), det. Bouček .

Biology. This species has been both recorded as a primary parasitoid and a secondary parasitoid (Kerrich 1973). In China, it was recorded as a secondary parasitoid from the cocoon of Braconidae sp. ( Hymenoptera). Distribution in China. Yunnan.

Remarks. Newly recorded from China. Pediobius erionotae is characterized with more vividly green body and a broad polished median band on scutellum. Among all members of the pyrgo -group, P. erionotae seems closer to P. imbreus and the recently described species, P. cajanus . Pediobius imbreus has body mostly dark with less metallic reflections, while P. erionotae has body mostly much more vividly green. Besides, P. erionotae has a smooth median band on scutellum which strikingly broader than that of P. imbreus . Some characters on scutellum, propodeum and petiole seem more reliable to distinguish P. erionotae and P. cajanus: in P. erionotae, scutellum smooth in median half, propodeum with a fine median carina and petiole strongly and finely reticulate and without longitudinal ridges on dorsal surface; while in P. cajanus, scutellum smooth in median third, propodeum without a fine median carina, petiole irregularly reticulate and with longitudinal ridges on dorsal surface (Taveras & Hansson 2015, figs 6–19).
