Diagnosis.

Belongs to the group with MV short and distinctly removed from anterior wing margin (Fig. 169), PMV absent and STV usually rudimentary. Notaspidium differs from Psilochalcis by having at least two anteriorly united carinae on T1 (absent in Psilochalcis ) and the scutellum arcuate, angulate or protruding apically (broadly rounded or truncated in Psilochalcis ).

Description.

Both sexes, length of body 1.5-2.7 mm. Body with bright to dull metallic refringence; flagellum tapering proximally, with two or three segments transverse; metasoma sessile; T1 dorsally more or less flattened and with at least some longitudinal carinae anteriorly united by a cross elevation or carina and mostly with angulate corners. Scutellum often posteriorly produced (rarely hardly so), sometimes into an angulate spine or horn, at least slightly protruding over metanotum; hind femur swollen with a basal large tooth followed by a comb of ventral teeth on outer margin.

Hosts.

Apanteles spp. ( Braconidae ) through Erisimus spp. ( Olethreutidae ); Pheidole titanis (Wheeler) and Scolytidae ( Coleoptera ) ( Bouček 1992).

Distribution.

India, Thailand, Vietnam (new report), Philippines, New Guinea and South America.
