Diagnosis.

Antenna with scape, pedicel and F1 yellow and rest of flagellomeres dark brown. Scutellum with median groove in approximately anterior 1/2. Legs mostly yellowish with fore and hind coxae yellowish white. Gaster yellowish except margins brown.

Description.

Female. Body length 1.9 mm, fore wing length 1.3 mm. Body yellow. Mandibles yellow with teeth brown. Antenna with scape, pedicel, and F1 yellow and remainder of flagellomeres dark brown. Legs mostly yellowish except fore and hind coxae yellowish white. Gaster yellowish except margins brown. Ovipositor black.

Head (Fig. 10 ) 1.3 × as wide as high in frontal view and ~ 2.3 × as wide as long in dorsal view. Lower face and vertex transversely reticulate, frons weakly sculptured. POL 2.4 × OOL. Malar space 0.4 × eye height. Occiput weakly reticulate. Relative measurements (length: width): scape = 35: 6; pedicel = 11: 6; F1 = 19: 6; F2 = 12: 7; F3 =13: 8; F4 = 12: 8; clava = 20: 8.

Mesosoma (Fig. 5 ). Midlobe of mesoscutum punctate with three pairs of long setae, lateral lobe of mesoscutum reticulate. Notauli ending laterad to inner angles of axilla. Axillae weakly reticulate and separated from each other. Scutellum with median groove in approximately anterior 1/2 and two pairs of long setae, sublateral grooves meet posteriorly. Spiracle with a transverse carina anteriorly, separated from metanotum by a distance almost as long as a diameter of spiracle; each propodeal callus with six setae.

Wings. Fore wing (Figs 5 , 7 ) 2.6 × as long as wide. Relative measurements (length): SMV = 33; MV= 45; PMV= 17; STV= 12. Hind wing (Figs 5 , 8 ) ~ 4.5 × as long as wide.

Metasoma (Fig. 5 ). Gaster ovate, 1.7 × as long as wide, and 1.2 × as along as mesosoma. Ovipositor exserted beyond apex of gaster.

Male. Unknown.

Host.

Unknown.

Distribution.

China (Shandong).

Etymology.

Latin: fossa = ditch, trench; and refers to the median groove in the approximate anterior 1/2 of scutellum.

Remarks.

Diglyphomorphomyia fossa is similar to D. aequus Zhu & Huang, 2003 in sharing the antenna with a yellow scape, pedicel, and F1, while the remaining segments are brown; and the notauli straight and converging posteriorly to meet laterad to inner angles of axillae, but the new species can be separated from D. aequus by the following combination of characters: legs yellowish with fore and hind coxae yellowish white (legs yellow in D. aequus ); gaster yellowish except margins brown (gaster yellow with a brown patch in D. aequus ); gaster 1.7 × as long as wide (gaster 1.4 × as long as wide in D. aequus ).
