Hockeria guptai Narendran, 1989: 109 (♀, holotype, India (CNC)).

Material.

1 ♀ (RMNH), "C. Vietnam: Ha Tinh, Vu Quang N. P., by hand[net], 1.x.2009, R. de Vries, RMNH’09”.

Diagnosis.

This species comes very near Hockeria tristis (Strand) because of the colour of the body and wings and in having micro-sculpture on the propodeum, but differs from Hockeria tristis in having: 1) T1 smooth and shiny (in Hockeria tristis T1 densely micro-sculptured); 2) mesopleuron not densely micro-sculptured as in Hockeria tristis and 3) apex of scutellum not as deeply emarginated as in Hockeria tristis .

Description

(based on specimen from Vietnam). ♀, length of body 4.8 mm.

Colour. Black with following parts as follows: eyes dull yellowish brown with dull brownish patches; ocelli pale reflecting yellow; fore and mid tarsi blackish brown; fore wing hyaline with 2 brown infuscations and a white patch adjacent to STV.

Head. Width of head in anterior view 1.2 × its height, distinctly wider than mesosoma (27:23); vertex and temples not narrow; POL 2.7 × OOL; AOL subequal to OOL; width between eyes 2.5 × POL; pre-orbital carina distinct, not distinctly joining malar sulcus, vertex with a carina -like ridge behind anterior ocellus (this ridge not clearly joining pre-orbital carinae to form a distinct horse-shoe like pre-orbital carina); height of malar sulcus 0.7 × height of eye in profile; eye height 1.3 × eye length in profile; post-orbital carina absent; geno-temporal furrow shallow; scrobe reaching anterior ocellus, cross reticulate-striate. Antennal scape reaching anterior ocellus. Relative lengths of antennal segments:scape = 57, pedicel = 15; ring segment = 7; F1 = 14; F2 = 15; F3 = 14; F4 = 13; F5 = 12.5; F6 = 11.5; F7 = 9; clava = 23.4.

Mesosoma. Mesosoma with close, umbilicate, setigerous pits, interstices carinate and rugose; posterior margin of pronotum arched posteriorly; length of middle lobe of mesoscutum a little shorter than scutellum (8:10); scutellum as long as wide, high in profile, apex bi-lobed. Propodeum with dense characteristic micro-sculpture on spaces between longitudinal carinae on sides; interstices densely micro-sculptured; postspiracular teeth well developed; callus with dense setae.

Wings. Fore wing 2.9 × longer than wide; relative length of SMV = 37; MV = 10; PMV = 4; STV = 2.

Legs. Hind coxa striate dorsally, densely pubescent ventrally; hind femur bi-lobed, 1.8 × as long as broad.

Metasoma. Metasoma subequal in length to mesosoma, 1.8 × as long as its width in dorsal view; T1 smooth and shiny; T2 smooth and shiny on dorso-median area, pubescent on dorso-lateral side; T6 densely rugose and weakly punctate; epipygium a little longer than ovipositor sheath in dorsal view.

Male. Unknown.

Host.

Unknown.

Distribution.

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

Variation.

Length of ♀ varies from 4.0-4.8 mm; height of malar sulcus distinctly longer than height of eye in Vietnamese specimen (according to the original description MS is shorter than height of eye in profile); POL 2.7-2.8 × OOL; median carina of propodeum not indicated in Vietnamese specimen; basal pit of T1 indistinct in Vietnamese specimen.
