Dolabraulax Quicke 1986 : Ent. Mon. Mag. 122 (1): 18; Type species: Dolabraulax implicatus Quicke 1986 .
General.
This genus may be separated from all other Braconinae by the combination of the following characters: scapus small, ventrally shorter than dorsally with dorso- and medio-basal expansions; propodeum posteriorly with a mid-longitudinal carina; and first metasomal tergite with the median area formed into a transverse ridge.
Dolabraulax is a small genus with only one species known from Java and the biology is unknown (Quicke, 1984). In this study, three new species of this genus are recognized, i.e. Dolabraulax jigongshanus sp. n., Dolabraulax brevivena sp. n. and Dolabraulax flavus sp. n., which are fully described and illustrated.
Key to the species of Dolabraulax Quicke
.
1. Propodeum with a completely mid-longitudinal carina or arising from the middle of the hind margin; vein 1-SR+M of fore wing slightly and evenly curved; smooth carina or band of second metasomal tergite relatively narrow baso-medially; fourth metasomal tergite with a transverse groove basally 2 - Propodeum with an incompletely mid-longitudinal carina, arising from the 1/3 of the hind margin; vein 1-SR+M of fore wing straight; smooth carina or band of second metasomal tergite wide baso-medially; fourth metasomal tergite without a transverse groove basally 3 2. Frons weakly impressed behind each antennal socket, hardly divided by a raised, mid- longitudinal ridge; notauli impressed along its entire length (Fig. 1c); body largely yellowish brown; length of body 3.8 mm (central China) Dolabraulax jigongshanus sp. n. - Frons deeply impressed behind each antennal socket, and distinctly divided by a raised, mid-longitudinal region; notauli only anteriorly impressed; body largely brown to black; length of body 4.9 mm (eastern Java) Dolabraulax implicatus Quicke 3. Face with long setae medially; propodeum with a longitudinal impressed area medially, densely setose laterally; vein r of fore wing short, 0.3 times as long as 2-SR (Fig. 3f); length of body 2.3 mm (eastern China) Dolabraulax brevivena sp. n. - Face without long setae medially; propodeum without a longitudinal impressed area, but with a longitudinal carina medially, sparsely setose laterally (Fig. 2e); vein r of fore wing relatively long, 0.5 times as long as vein 2-SR (Fig. 2f); length of body 3.0-4.5 mm (south-western China) Dolabraulax flavus sp. n.
