Type material.

Holotype, ♀ [NEFU; on card], China, Hainan Province, Wenchang City, Dongjiao Town, 22-24 IV 2019, leg. Yu-Ting Jiang, by yellow pan trapping. Paratypes: 2♀ [on slides], same data as holotype.

Diagnosis.

Antennae yellowish brown with scape yellow. Midlobe of mesoscutum with two pairs of long setae. Legs mostly yellowish white with fore and hind coxae white, mid coxae yellow.

Description.

Female. Body length 1.8 mm, fore wing length 1.5 mm. Body yellow. Antennae yellowish brown with scape yellow. Legs mostly yellowish white except fore and hind coxae white, mid coxae yellow. Gaster dorsally mostly yellow with a brown patch and lateral margins brown, ventrally mostly whitish.

Head (Figs 11 , 13 ) 1.4 × as wide as high in frontal view and 2.4 × as wide as long in dorsal view. Frons weakly sculptured. Vertex with engraved reticulation, meshes isodiametric. POL 2.4 × OOL. Malar space 0.3 × eye height. Occiput weakly reticulate. Relative measurements (length: width): scape = 29: 5; pedicel = 11: 5; F1 = 13: 5; F2 = 10: 5; F3 = 10: 6; F4 = 9: 6; clava = 15: 5.

Mesosoma (Fig. 15 ). Notauli straight, ending laterad to inner angle of axilla. Midlobe of mesoscutum punctate with two pairs of long setae, lateral lobe of mesoscutum reticulate. Axillae weakly reticulate and separated from each other. Scutellum longer than mesoscutum with two pairs of long setae, sublateral grooves meet posteriorly. Spiracle with a transverse carina anteriorly, slightly separated from metanotum by a distance shorter than a diameter of spiracle; each propodeal callus with seven or eight setae.

Wings. Fore wing (Fig. 14 ) 2.3 × as long as wide. Speculum narrow. Relative measurements (length): SMV = 35; MV= 36; PMV= 16; STV= 12. Hind wing (Fig. 16 ) ~ 4.0 × as long as wide.

Metasoma (Fig. 12 ). Gaster ovate; 1.8 × as long as wide and 1.3 × as long as mesosoma. Ovipositor exserted beyond apex of gaster.

Male. Unknown.

Host.

Unknown.

Distribution.

China (Hainan).

Etymology.

The specific name is derived from the type locality.

Remarks.

Diglyphomorphomyia hainana is similar to D. aequus Zhu & Huang, 2003 in sharing a body that is mostly yellow, and a gaster bearing a brown patch, but can be separated from D. aequus by the following combination of characters: antennae yellowish brown with scape yellow (antenna brown with scape, pedicel, and F1 yellow in D. aequus ); POL 2.4 × OOL (POL 2.8 × OOL in D. aequus ); legs mostly yellowish white with fore and hind coxae white, mid coxae yellow (legs yellow in D. aequus ).
