Coeloides changbaiensis Wang et Chen , sp. nov. ( Figs. 6–11 )

Material studied. Holotype female: CHINA, Jilin, Changbai Mountain, 9.vii.1977, He Junhua, No. 770746 ( ZJUH).

Description (Female). Length of body 3.5 mm, fore wing 3.8 mm, ovipositor 3.3 mm. Head: Antennae incomplete, with 30 segments remaining; scapus suboblique, dorsally longer than ventrally and 1.9 times as long as its apical width; pedicel 0.4 times as long as scapus; first flagellomere longer than pedicel, its apex ventro­lateral rather flared, 1.3 times as long as wide; second flagellomere 1.2 times as long as first one, ventrolaterally slightly flared apically; third flagellomere not flared, 1.3 times longer than second one; face largely smooth and shiny, sparsely setose medially and densely setose laterally; malar suture deep; height of clypeus: distance inter­tentorial: distance tentorial­ ocular= 3: 8: 5; length of maxillary palp 0.6 times height of head; length of eye in dorsal view 1.1 times temple; temple smooth and densely setose; frons between antennal sockets and ocelli distinctly impressed; shortest distance between posterior ocelli: minimum diameter of posterior ocelli: minimum distance between posterior ocellus and eyes= 2: 4: 13.

Mesosoma: Length of mesosoma 1.5 times its maximum height; pronotum and propleuron smooth; mesoscutum setose; notauli deep anteriorly, and shallow posteriorly, with sparse setae along its entirely length; scutellum flattened, densely pubescent; scutellar sulcus deep and moderately wide, crenulate; metanotum with distinct medio­longitudinal carina; propodeum sparsely setose, without mid­longitudinal carina or furrow.

Wing: Fore wing: length of veins r: 3­SR: SR1 = 5: 10: 35; vein 1­SR+M weakly curved; length of veins 2­SR: 3­SR: r­m = 8: 10: 6; vein cu­a weakly postfurcal. Hind wing: length of veins SC+R: 1r­m = 13: 7, vein 2­SC+R longitudinal, short and about 0.3 times as long as vein 1r­m.

Leg: Length of femur, tibia and tarsus of fore leg = 19: 22: 33; length of femur, tibia and basitarsus of hind leg = 24: 39: 14, and 3.3, 7.8 and 4.4 times their maximum width, respectively; tibia of hind leg without lateral furrow.

Metasoma: Metasomal tergites smooth. First metasomal tergite slightly narrowed apically, largely smooth and shiny, and with strongly raised carina medially and areolate laterally, 1.2 times as long as its apical width; second metasomal tergite smooth except for a striolate medio­basal area, with lateral diverging grooves and raised carina sublateraly; the suture between second and third metasomal tergites narrow, curved medially, deep and weakly crenulate; remainder of metasomal tergites smooth and sparsely setose, without antero­lateral carina or grooves; hypopygium rounded apically, not protruding beyond the apex of apical metasomal tergite; length of ovipositor 1.1 times length of metasoma, and 0.8 times fore wing.

Color: Body largely yellowish­brown but head yellowish.

Diagnostic characters: This species is similar to Coeloides abdominalis (Zetterstedt) , but can be separated from the latter by the combination of the following characters: the rounded temple, the weakly curved vein 1­SR+M, the postfurcal vein cu­a of fore wing, the reddish yellow mesosoma and metasoma, and the second metasomal tergite without lateral raised areas.

Biology: Unknown.

Etymology: From Changbai, referring to the location of type specimen.
