Material.

1 ♀ (RMNH), "Vietnam: Ninh Thuân, Núi Chúa N. P., northeast part, Mal[aise] traps, 90-150 m, 23-30.v.2007, C. v. Achterberg & R. de Vries, RMNH’07”.

Diagnosis.

This species comes near Kriechbaumerella mansues ( Nikol’skaya) in the key to species of Oriental Kriechbaumerella by Narendran (1989), but differs from Kriechbaumerella mansues in having: 1) interstices of pits on mesonotum narrower than diameter of pits and nearly rugose (in Kriechbaumerella mansues interstices of pits of mesonotum broader, smooth and shiny); 2) hind femur black (in Kriechbaumerella mansues hind femur mostly or entirely red), and 3) T6 shallowly pitted and pits rugoso-punctate (in Kriechbaumerella mansues T6 with pits deeper and not rugose).

Description.

♀, length of body 8.0-8.5 mm.

Colour. Black; tip of antennae, fore tarsi, fore femur and mid tarsi black with liver brown tinge; fore wing with deep blackish brown infuscations adjoining MV; POL 3.5-5.0 × OOL.

Head. Antenna with scape reaching front ocellus; pre-orbital carinae distinct; post-orbital carina weakly represented, running upwards; geno-temporal furrow absent; scrobe reaching anterior ocellus.

Mesosoma. Apex of scutellum well produced posteriorly with a median emargination.

Wings. Fore wing with PMV 1.2-1.5 × length of MV. Metasoma with T1 micro-sculptured dorsally (at least partly); posterior margin of T1 straight; T2 to T6 with larger pits on dorso-lateral parts; T6 rugoso-punctate; epipygium carinate at middle, longer than median length of T6; ovipositor sheath subequal in length to epipygium or distinctly shorter than epipygium in dorsal view.

Male. Unknown.

Host.

Latoia lepida (Cramer) ( Lepidoptera : Limacodidae ).

Distribution.

India, Vietnam (new record for Vietnam).

Variation.

In the Vietnamese specimen the antenna, fore femur and middle tarsus are without liver brown tinge and the fore wing has two large dark brown patches, one adjoining MV and the other beyond PMV.
