Type species.

Orientocardiochiles joeburrowi Kang, sp. nov.

Diagnosis

(based on all the members of the genus). Body large and stout, finely sculptured, whitish to yellow pale in color with black spots and stripes. Head in dorsal view transverse. Antenna 41- or 43-segmented. Eyes sparsely pilose. Clypeus with distinct suture and two clypeal tubercles present apically. Malar suture present. Mandible bidentate and angularly bent ventrally. Mouthparts (the length of galea and glossa) short. Maxillary palpus 5- or 6-segmented. Labial palpi 4-segmented. Notauli deep, crenulate, meeting posteriorly in deep smooth area. Scutellar sulcus curved, with 5+ crenulae. Scutellum more or less elevated medially, without carina laterally and apically. Propodeal areola completely developed and kite-shaped or elongated pentagonal. Epicnemial carina absent. Mesopleuron mostly smooth; precoxal sulcus well-defined and crenulate, not reaching posterior margin. Metapleuron rugulose. Mesosternal sulcus finely crenulate. Hind tibia without apical projection; inner tibial spur distinctly longer than outside spur, subequal to half of hind basitarsus. Tarsal claws pectinate. Forewing with elongated pterostigma; vein r reach ing at apical fourth of pterostigma; SR1 sharply angled at basal fourth; basal fourth of vein SR1 almost perpendicular to apical vein 3-SR. Vein 1a present as a spectral short trace; 1st discal cell in forewing rather short compared to first submarginal cell. Second submarginal cell elongated. First subdiscal (brachial) cell broad. M+CU in hind wing distinctly shorter than 1-M. Hind wing with 6 hamuli. T1 widened apically, with lateral suture clearly defined throughout. T2 mostly rugose except for plateau-like projection (Figs 2D , 5G ); plateau-like projection of T2 present at anteromedial base. T3 entirely smooth. Hypopygium sharply pointed at apex, median longitudinal area evenly sclerotized or largely desclerotized medially throughout; median enfold of hypopygium present or absent. Ovipositor sheath longer than metasoma, pointed at apex, and with short setae throughout.

Distribution.

Oriental (Malaysia, Vietnam).

Biology.

Unknown.

Etymology.

The name for the genus refers to Cardiochiles from the Oriental region. From “orientum” (Latin for the eastern region) and the generic name " Cardiochiles Nees, 1819." Gender: masculine.

Notes.

Orientocardiochiles gen. nov. will run to couplet 9 in the key to world genera by Dangerfield et al. (1999), but it can be distinguished from Austerocardiochiles in the couplet 9b of the key as follows:
