Biting the bullet: revisionary notes on the Oraseminae of the Old World (Hymenoptera, Chalcidoidea, Eucharitidae) Burks, Roger A. Heraty, John M.

Refers to the rough propodeal and petiolar surface sculpture.  Diagnosis. Flagellum with 7 funiculars (Fig. 30). Prepectus rugose, mostly smooth, and without evenly reticulate sculpture as in all other species. Supraclypeal area and clypeus smooth (Fig. 29). Mesoscutal midlobe strongly elevated anteriorly; pronotum with rounded anterolateral protrusions (Fig. 32). Propodeal disc evenly areolate, with irregular, incomplete median carina (Fig. 34). This species keys to  O. initiatorin Heraty (1994), but differs by having a proportionally longer antennal flagellum to head height (1.3 versus 1.1-1.2), longer F2 (2.0 versus 1.4-1.5), frenum finely rugose-reticulate (versus reticulate), and a distinctly areolate (versus finely reticulate or nearly smooth) propodeum. It will key to  O. assectatorin Girish Kumar and Sureshan (2015), but differs most distinctly by the rugose versus reticulate prepectus.  Female. Length 3.5 mm. Head, mesosoma, and petiole black with slight metallic blue to purple luster. Antenna pale yellow. Coxae black to dark brown, with faint metallic purple luster; femora dark brown except white at tips; tibiae and tarsi pale yellow. Fore wing venation yellowish-white. Gaster dark brown.  Head(Figs 29-30) 1.4 xas broad as high. Face rugose-reticulate; supraclypeal area and clypeus smooth; anteclypeus absent; vertex reticulate. Labrum with 4 digits. Palpal formula 3:3 but with minute 2nd palpomeres. Flagellum 1.3 xheight of head; anellus transverse; F2 2.0 xas long as broad, F2 1.3 xas long as F3.  Mesosoma(Figs 31- 34). Pronotum with small protrusion ventral to mesothoracic spiracle (Fig. 32: protrusion). Mesoscutum finely rugose-reticulate, posterior margin sinuate and midlobe strongly convex posteromedially, mesoscutal midlobe abruptly elevated above lateral lobes; notauli broadly and deeply impressed anteriorly. Axilla finely rugose-reticulate; mesoscutellar disc finely rugose-reticulate; frenal line as a deep groove with a carinate edge posteriorly; frenum finely rugose-reticulate; axillular sulcus not indicated, axillula finely rugose-reticulate. Mesepisternum anteriorly with a smooth area dorsolaterally, laterally finely reticulate and ventrally smooth; not overlapping prepectus; ventrally smooth and forming a rounded horizontal surface anterior to mesocoxae; upper mesepimeron elevated and smooth; transepimeral sulcus foveate; lowermesepimeron glossy, shallowly irregularly sculptured. Propodeal disc medially areolate with some underlying irregular sculpture, with irregular median carina that is present only for a short distance nearpropodeal midlength, sublaterally rugose-reticulate; callus bare, smooth over most of surface but coarsely areolate to foveate peripherally, including foveate depression separating metapleuron from hind wing base. Metacoxa rugose-reticulate, glossy posteriorly. Fore wing 2.4 xas long as broad; costal cell with ventral row of setae apically, bare basally; basal cell with 2 ventral setae anteriorly; speculum present, partially crossed by a patch of ventral setae nearmidlength of fore wing; cubital fold with only a single ventral seta posterior to basal cell, bare posterior to speculum; subcubital fold bare posterior to basal cell, with only some ventral setae posterior to speculum; wing disc covered by dense long setae (Fig. 33); stigmal vein 2.0 xas long as broad, only slightly expanded at uncus; postmarginal vein about 3.0 xas long as stigmal vein. Hind wing costal cell with only a few ventral setae apically.  Metasoma(Figs 34-35). Petiole 1.7 xas long as broad; 0.9 xas long as metacoxa, with sharp anterior transverse carina, areolate and with a complete dorsal median carina. Antecostal sulcus of Gs1 finely sculptured laterally, becoming smooth and very shallow medially; acrosternite smooth. Hypopygium with a few short setae, and 1 slightly longer posterolateral seta on each side. Ovipositor dorsal valve with 7 medially interrupted annuli; ventral valve with 7-8 minute teeth along lateral carina, with only a rounded elevation basal to toothed apex.  Male. Unknown.  Material examined.    Holotype: Vietnam: Thua Thien-Hue: Bach Ma Natl.
