Two new species of Deutereulophus Schulz, D. felix sp. nov. and D. daguisiensis sp. nov., are described from China. A key to species of Deutereulophus known from China is provided.
Chalcidoidea, Eulophinae, tennysoni species-group, parasitoid, taxonomy
Deutereulophus Schulz is one of several small genera of the tribe Eulophini, subfamily Eulophinae (Hymenoptera: Eulophidae). Species of the genus are distributed in all zoogeographic regions, except for the Afrotropical region. Currently Deutereulophus contains 23 valid species (
The genus Deutereulophus (as Entedonomorpha Girault) was subdivided into two species groups by
All specimens were collected by sweeping or yellow-pan trapping, and were dissected and mounted in Canada balsam on slides following the method of
Terminology follows the
F1–3 flagellomeres 1–3;
MV marginal vein;
OOL minimum distance between a posterior ocellus and corresponding eye margin;
PMV postmarginal vein;
POL minimum distance between posterior ocelli;
SMV submarginal vein;
STV stigmal vein.
All type material is deposited in the insect collections at Northeast Forestry University (NEFU), Harbin, China.

Holotype , ♀ [NEFU; on card], China, Hunan Province, Chenzhou City, Yongxing County, Bianjiang Town, Pengjiawan Village, 23–25. VII. 2021, Shu-Chen Deng, by yellow-pan trapping. Paratypes: 4♀ [2 ♀ on slide, 2 ♀on cards], same data as holotype.
Head and mesosoma black. Face strongly reticulate with large meshes. Antennal scrobes smooth. Vertex with scattered pits. Antenna yellow with scape pale yellow. Female funicle 3-segmented, clava 4-segmented. Mesoscutum strongly reticulate with large meshes. Sublateral grooves on mesoscutellum converging and meeting posteriorly. Legs mostly yellowish-white. Metasoma yellow with margins dark brown to black.
Female. Length 1.4 mm, fore wing length 1.0 mm. Head and mesosoma black. Eyes gray. Ocelli pale yellow. Antenna yellow with scape pale yellow. Mandibles dark brown. Petiole black. Metasoma yellow with margins dark brown to black. Legs mostly yellowish-white. Wings hyaline with veins brown.

Named after the Latin adjective felix, meaning lucky.
The new species is similar to Deutereulophus marginatus, and can be separated using the key given above.

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 yellowish-white 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.
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.

China (Hubei).
Named after the type locality, the Daguisi National Forest Park in Hubei Province.
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 cup-shaped area anteromedially (without a raised triangular cup-shaped area in malabarensis).
