﻿Two new species of Deutereulophus Schulz (Hymenoptera, Eulophidae) from China, with a key to Chinese species

﻿Abstract Two new species of Deutereulophus Schulz, D.felixsp. nov. and D.daguisiensissp. nov., are described from China. A key to species of Deutereulophus known from China is provided.

The genus Deutereulophus (as Entedonomorpha Girault) was subdivided into two species groups by Bouček (1988). This study describes two new species of the genus within the tennysoni-group and provides a key to all species occurring in China.

Material and methods
All specimens were collected by sweeping or yellow-pan trapping, and were dissected and mounted in Canada balsam on slides following the method of Noyes (1982), or mounted on a card. Slide-mounted specimens were photographed with a digital CCD camera attached to an Olympus BX51 compound microscope. Specimens on cards were photographed with an Aosvi AO-HK830-5870T microscope. Measurements were made using the built-in software of Aosvi AO-HK830-5870T. The quality of these photos was improved by using Helicon Focus 7 and Adobe Photoshop 2020.
All type material is deposited in the insect collections at Northeast Forestry University (NEFU), Harbin, China.

Key to Chinese species of Deutereulophus
Mesosoma (Figs 1, 5) 1.4× as long as wide. Pronotum rectangular, strongly reticulate with large meshes, covered with numerous setae and 2 considerably long setae posteromedially, without transverse carina along anterior margin of pronotal collar. Mesoscutum strongly reticulate with large meshes, midlobe of mesoscutum with 2 pairs of long setae. Axillae slightly advanced with faint reticulation. Mesoscutellum weakly reticulate, meshes of reticulation smaller and shallower than meshes on mesoscutum, with 2 pairs of long setae; sublateral grooves united posteriorly. Propodeum about 0.5× as long as length of mesoscutellum measured medially, smooth, median carina split and diverging posteriorly, plicae and paraspiracular carina present; spiracles separated from metanotum by a distance shorter than their own diameter; each propodeal callus with 9 setae.

Remarks.
The new species is similar to Deutereulophus marginatus, and can be separated using the key given above. Diagnosis. Head and mesosoma black. Vertex with scattered pits. Antennal scrobes smooth. Antenna yellowish-white with F3 dark brown, clava dark brown with apex yellowish-white. Female funicle 3-segmented, clava 4-segmented. Legs yellowishwhite with procoxa and profemur dark brown. Face with raised reticulation. Metasoma dark brown. Mesoscutum strongly reticulate with large meshes. Sublateral grooves on mesoscutellum converging and meeting posteriorly. Propodeum with a raised triangular cup-shaped area anteromedially, median carina split and diverging posteriorly.

Deutereulophus daguisiensis
Description. Female. Length 2.4 mm, fore wing length 1.7 mm. Head and mesosoma black. Eyes gray. Ocelli pale yellow. Antenna yellowish-white with F3 dark brown, clava dark brown with apex yellowish-white. Mandibles dark brown. Petiole black. Metasoma dark brown. Legs yellowish-white with procoxa and profemur dark brown. Wings hyaline with veins brown.
Mesosoma (Fig. 6) 1.4× as long as wide. Pronotum rectangular with raised reticulation, covered with numerous setae, without transverse carina along anterior margin of pronotal collar. Mesoscutum strongly reticulate with large meshes. Axillae advanced anteriorly with faint reticulation. Mesoscutellum weakly reticulate, meshes of reticulation smaller and shallower than meshes on mesoscutum, with 2 pairs of long setae; sublateral grooves meeting posteriorly. Propodeum smooth; anteromedially with a raised triangular cup-shaped area; median carina split and diverging posteriorly; spiracles separated from metanotum by a distance shorter than their own diameter.
Metasoma (Figs 6, 7) almost as long as mesosoma. Petiole rugose, wider than long in dorsal view. Metasoma rounded, as long as wide; first tergite 0.4× as long as length of metasoma. Ovipositor exserted beyond apex of metasoma.
Male. Unknown. Host. Unknown. Distribution. China (Hubei). Etymology. Named after the type locality, the Daguisi National Forest Park in Hubei Province.
Remarks. The new species is similar to D. malabarensis Narendran, but can be separated from it by the following combination of characters: antenna yellowish-white with F3 dark brown, clava dark brown with apex yellowish-white (antenna dark brown except pale scape in malabarensis); sublateral grooves on mesoscutellum converging and meeting posteriorly (not meeting posteriorly in malabarensis); propodeum with a raised triangular cupshaped area anteromedially (without a raised triangular cup-shaped area in malabarensis).
