Description
Female: Length of body
21 mm
, of fore wing
18 mm
, of ovipositor
24 mm
.
Antennae with 126 flagellomeres, terminal flagellomere 2.6 times longer than wide. Height of clypeus:inter-tentorial distance:tentorio-ocular distance51.0:3.5:3.2. Width of face:width of head:height of eye51.2:2.2:1.0. Height of face:width of face51.0:2.2. Face punctate with hairs, smooth triangle-shaped area on top of clypeus and a narrow smooth line continuing upwards from it between toruli. Frons smooth, sparsely punctulate, depressed on median area around longitudal groove. POL:transverse diameter of posterior ocellus:shortest distance between posterior ocellus and eye51.0:1.0:3.5. Length of eye in dorsal view:distance of occiput and posterior margin of eye52.0:1.0.
Mesosoma approximately 1.5 times longer than maximally deep.
Fore wing: length of veins r:3-SR:SR151.0:2.5:3.5. Length of veins 2-SR:3-SR:rm51.0:2.4:1.3. Length of veins m-cu:2-M51.0:2.8. Length of veins 1-CU1:2- CU151.0:4.1. Shape of vein 1-SR+M straight. Swelling in vein 3-CU1 1.7 times thicker than the other part of the vein.
Legs: Length of fore femur:tibia:tarsus52.0:2.1:1.0. Fore basitarsus 5.0 times longer than deep. Two foretibial spurs. Length of hind femur:tibia:tarsus52.0:2.7:1.0. Hind basitarsus 2.8 times longer than deep.
First metasomal tergite 1.6 times longer than wide; raised median area sometimes weakly medially longitudinally depressed, smooth. Posterior margin smooth, or with dense striation or strong scarce strigation. Second tergite 1.4 times wider than long; raised median area strigated, antero-medial triangular area not raised or conspicuous. Third tergite 1.9 times wider than long; with strigated transverse furrows on anterior and subposterior margins, raised median area longitudinally strigose to reticulate rugose. Antero-lateral areas raised and smooth. Tergites four and five similar. Tergites six and seven smooth.
Orange-brown except for apex of mandibles which are black. Wings fairly evenly weakly darkened, with two hyaline zones in fore wing below pterostigma and basally to veins 1-M and cu-a. Apical quarter of pterostigma darkened. Hind wing darkened with two hyaline areas around vein 1-M and costal and marginal cells.
Notes
The type of
B. nigriceps
could not be located [though it was seen by
Quicke and van Achterberg (1990)
]. However, the original description agrees well with the
type
of
B. lucidus
and the two specimens identified as
nigriceps
in the RMCA are also conspecific.
