Type species.
Parallobracon prolatus
sp. nov.
Diagnosis.
Antennomeres (except scape and pedicel) square; scapus rather slender, and in lateral view without double margin at inner side apically and apex strongly protruding ventrally; eye glabrous, not emarginated; face flattened in lateral view; clypeus flat and with distinct dorsal carina; malar suture present but weak, with dense short setae; labio-maxillary complex normal, not elongate; frons with strong median groove, largely smooth; notauli quite shallow, and impressed anteriorly on disc; scutellar sulcus comparatively narrow, and sparsely crenulate; metanotum convex medially, but without median carina anteriorly; propodeum smooth, and without medio-longitudinal carina or groove; first discal cell of fore wing nearly parallel-sided and ca. 3.0
x
longer than vein m-cu; vein 1-SR+M of fore wing straight; vein 1r-m of hind wing ca. 5.0
x
longer than vein 2-SC+R; vein 1-SR of fore wing distinctly oblique and pointing basad of vein cu-a, angle with vein C+SC+R ca. 55°; fore wing vein cu-a weakly postfurcal; vein 2-SC+R of hind wing transverse, distinctly shorter than vein 1r-m; hind wing with densely setae basally; claws simple; legs more or less with sparsely setae; in dorsal view, metasoma ovoid; median area of T I developed and coarsely sculptured posteriorly; medio-basal area of T II wide subbasally and acute apically, latero-basal areas triangular and medium-sized and posterior half of tergite with pair of diverging depressions; second suture deep and wide, crenulate, narrowed and curved upward laterally, weakly curved medially; T III with developed antero-lateral areas and posterior margin of tergite sinuate, and 3.8
x
wider than its median length (excluding its basal groove); T III-V with crenulate transverse subposterior groove; T III-VII largely smooth; ovipositor with minute ventral teeth and without dorsal nodus.
Distribution.
Oriental (China).
Etymology.
Named after the nearly parallel-sided first discal cell of the fore wing (
parallelus
is Latin for "sides of equal distance"). Gender: masculine.
Note.
This new genus will run in existing keys to
Cyanopterus
Haliday, 1835 (e.g., Belokobylskij 2000), but can be separated from the latter by the following characters: first discal cell of fore wing nearly parallel-sided and elongate (first discal cell of fore wing widened basally in
Cyanopterus
); vein 1r-m of hind wing quite long and ca. 5.0
x
longer than vein 2-SC+R (vein 1r-m of hind wing at most ca. 2.0
x
longer than vein 2-SC+R in
Cyanopterus
); vein 1-SR of fore wing distinctly oblique and pointing basad of vein cu-a (less oblique and pointing to vein cu-a in
Cyanopterus
); second submarginal cell of fore wing widened distally (second submarginal cell of fore wing parallel-sided in
Cyanopterus
); apex of scapus strongly protruding ventrally (apex of scapus slightly protruding ventrally in
Cyanopterus
); clypeus with distinct dorsal carina (clypeus usually without dorsal carina in
Cyanopterus
).
