Diagnosis.

In the key to Oriental species of Hockeria ( Narendran 1989) Hockeria bangalorica comes near Hockeria lankana Narendran, but differs from it in having: 1) metasoma longer than mesosoma (in Hockeria lankana metasoma shorter than mesosoma); 2) pre- and post-orbital carinae present (in Hockeria lankana pre- and post-orbital carinae absent); and 3) apex of scutellum broadly emarginate and bi-dentate (in Hockeria lankana apex of scutellum less broadly emarginate and bi-lobed).

Description.

♀, length of body 2.9-5.5 mm.

Colour. Black; scape, pedicel, ring segment and F1 yellowish brown; fore and middle legs and tegula yellowish brown; hind femur yellowish brown basally and apically, middle part blackish brown or black; metasoma brown ventrally; fore wing with two brown infuscations with a medial hyaline spot.

Head. Head wider than mesosoma, scrobe not reaching front ocellus; pre-orbital carina distinct; post-orbital carina running upwards behind posterior margin of eye; malar ridge 0.4 × height of eye in profile; eye length in profile 0.8 × its height; geno-temporal furrow absent. POL 9.5 × OOL. Antenna (fig. 79 in Narendran 1989) with scape almost reaching anterior ocellus.

Mesosoma. Mesosoma with close pits, interstices narrower than diameter of a pit, rugose; apex of scutellum bi-lobed; scutellum somewhat flat.

Wings. Fore wing with PMV more than 2-3 × longer than STV, longer than MV.

Legs. Hind coxa with a week dorsal raised carina; hind femur weakly bi-lobed ventrally.

Metasoma. Metasoma longer than mesosoma, T1 with two basal carinae and a median fovea in between; carinae shorter than width between them.

Male. Resembles female, but with longer antennal segments and the fore wing has no infuscation.

Host.

Unknown.

Distribution.

Vietnam (new record), Malaysia, India ( Narendran 1989).

Variation.

The Vietnamese specimens show the following variation from the type. The yellowish brown colour of scape, pedicel, ring segment and F1 tends to become brownish yellow; fore and middle coxae are black; hind tibia and tarsi brownish; POL 5 × OOL; scutellum moderately convex; dorsal carina of hind coxa stronger; basal carinae of T1 longer than space between them.
