Diagnosis.

This species resembles the European Haltichella rufipes (Olivier) in general appearance, but the apical teeth of scutellum are more widely spaced (more than 1.5 × as wide as distance from each other in Haltichella nipponensis ) (in Haltichella rufipes distance almost equal to their length; Habu 1960). Differs from Haltichella achterbergi Narendran, 1990, by having the dorsal carinae of the first metasomal tergite widely spaced (close to each other in Haltichella achterbergi ) and apical teeth of scutellum diverging (parallel-sided in Haltichella achterbergi ).

Description.

♀, length of body 2.8-4.1 mm.

Colour. Black; antenna brown, slightly reddish, F3 to tip of clava blackish; apical teeth of scutellum large and slightly reddish; fore and middle coxae, trochanters, femora slightly dark; hind coxa and femur almost black or reddish black with hind trochanter and base of hind femur brown; hind tibia almost black or reddish.

Head. Antennal scape reaching anterior ocellus, longer than combined length of F1 to F4; eyes pubescent.

Legs. Hind coxa with coxal tooth on baso-dorsal side; hind femur 2.3 × as long as wide, smooth without micro-sculpture.

Male. Length of body 2.7-3.1 mm. Differs from ♀ mainly by having micro-sculpture on T1.

Variation.

In Vietnamese specimens fore and middle legs (except coxae) are more yellowish brown with reddish tinge than in Indian specimens and scutellum not reddish apically, but black.

Distribution.

Japan, India, Vietnam (new record).
