( Figs 5–6 )

Helconidea Viereck, 1914: 67 . Type species: Helcon aequator Nees, 1812 ( Pimpla dentator Fabricius, 1804 ), by original designation. Hedqvist, 1967: 136 –140; van Achterberg, 1987: 272; Chou et Hsu, 1998: 297; Belokobylskij, 1998: 26 –40, 412–413, 415–418.

Diagnosis. Antenna of ♀ without white band and basal half of antenna dark brown; occipital carina distinctly curved above base of mandible, often nearly rectangularly angled with hypostomal carina and connected to hypostomal carina distinctly above base of mandible, resulting a distinct occipital flange; propleuron more or less convex; mesopleuron in front of prepectal carina oblique, gradually lowered ( Fig. 4 C); prepectal carina absent medio-ventrally; area in front of tegulum without carina and punctate or punctulate; mesosternal sulcus normal; marginal cell of hind wing comparatively narrow apically; hind femur with a ventral tooth-shaped protuberance ( Figs 5 D, 6D); hind tarsus brown; basal part of first metasomal sternite longer than wide and basally sculptured, well separated from tergite; third and following metasomal tergites smooth; apical half of ovipositor sheath with fine erect setae ( Figs 5 F); ovipositor sheath 1.4–1.7 times as long as fore wing and 1.21.3 times as long as body.
