Microplitis leucaniae Xu & He, 2002: 153  ; Chen & Song 2004: 225 Holotype ZUH.

Female. Body length 3.1 mm.

Head: Head not broadening behind eyes in dorsal view, 1.8 × as wide as long ( Fig. 11View FIGURE 11 -B); face convex, 1.3 × as wide as long, rugose ( Fig. 11View FIGURE 11 -B); eyes large, 1.6 × as high as broad, inner margin of eyes parallel; clypeal margin convex ( Fig. 11View FIGURE 11 -B); frons rugose, vertex and upper temple rugose-punctate; antenna longer than body ( Fig. 11View FIGURE 11 -A); eyes 1.2 × as wide as long in dorsal view; frons rugose; lateral temples; POL 0.8 × OOL; ocelli forming an obtuse angle; scape 1.5 × as long as wide; first flagellomere 4.5 × as long as wide; terminal flagellomere acute, 3 × as long as wide.

Mesosoma: Mesosoma 1.5 × as long as high; mesoscutum rugose-punctate with a wide and deep mediolongitudinal crenulate furrow, middle lobe and lateral lobes sculptured and punctate; notauli well developed, represented by coarsely crenulate furrows meeting posteriorly to form a sunken rugose-reticulate area; dorsal scutellum coarsely rugose, bordered laterally by crenulate furrow forming distinct carinate margin ( Fig. 11View FIGURE 11 -C); scutellar lunules wide medially, divided by five carinae ( Fig. 11View FIGURE 11 -C & D), area lateral to scutellar lunules flat; dorsal scutellum rugose; propodeum with percurrent medial longitudinal carina, coarsely rugose ( Fig. 11View FIGURE 11 -D); pronotum densely rugose; precoxal sulcus crenulate; anterior and lower part of metapleuron coarsely rugose, rest smooth; hind coxa rugose basally, rest smooth; hind femur 4.1 × as long as wide; hind tibial spur 0.3 × as long as basitarsus.

Wings: Fore wing 2.7 × as long as wide ( Fig. 11View FIGURE 11 -F); pterostigma 3 × as long as wide ( Fig. 11View FIGURE 11 -F); 1 -R 1 1.7 × as long as its distance from apex of radial cell, and 0.95 × as long as pterostigma respectively; areolet rectangular ( Fig. 11View FIGURE 11 -F); first distal cell 1.2 × as long as high; 1 -CU 1 0.4 × as long as 2 -CU 1; 1 -M slightly curved ( Fig. 11View FIGURE 11 -F), 1.6 × as long as m-cu; 1 -SR 0.23 × as long as 1 -M; m-cu 1.6 × as long as 2 -SR+M; cu-a of hind wing feebly curved to basal; submarginal cell of hind wing 1.7 × as long as basal width; hind wing vannal lobe convex, setose ( Fig. 11View FIGURE 11 -F).

Metasoma: T 1 2.1 × as long as wide, rugose, parallel sided, smooth postero-medially, weakly narrowing in posterior 1 / 3 ( Fig. 11View FIGURE 11 -D); T 2 smooth with an indistinct median field, and as wide as T 3 ( Fig. 11View FIGURE 11 -D & E); medial length of T 3 as long as T 2; T 2 –T 7 smooth, sparsely setose ( Fig. 11View FIGURE 11 -E); T 3 with transverse row of setae; ovipositor sheath long, 0.33 × as long as hind tibia, setose apically.

Colour: Body black, antenna reddish yellow except distal 7–8 flagellar segments blackish ( Fig. 11View FIGURE 11 -B), tip of mandible reddish yellowish brown, palps, tegulae, T 2 –T 5 of abdomen ( Fig. 11View FIGURE 11 -E), sternites and hypopygium reddish yellow, all spurs yellowish, coxa black, fore, mid and hind legs reddish yellow ( Fig. 11View FIGURE 11 -E) but in basal 1 / 5 of hind tibia blackish and distal part of tarsi brown, fore and hind wings hyaline, pterostigma blackish with a yellow patch in basal 1 / 3 ( Fig. 11View FIGURE 11 -F), venation brown.

Male: Body length 3.1 mm, penultimate flagellomere 3.1 × as long as wide, T 2 and T 3 red and yellow, coxae dark brown.

Distribution. China (Fujian, Guangxi, Xinjiang and Zhejiang).

Host. Leucania separata (Walker)  , Spodoptera  (= Prodenia  ) litura (Fab.)  , Heliothis  (= Helicoverpa  ) armigera (Hübner)  .

Discussion. This species is close to M. longwangshana  in having the absence of longitudinal carina between antennal sockets, indistinct medial longitudinal carina on propodeum. It differs from M. longwangshana  in the following characters: medial furrow on mesoscutum distinct (in M. longwangshana  mesoscutum without a medial furrow), scutellum rugose (in M. longwangshana  scutellum micropunctured), T 1 with medial longitudinal groove (T 1 without medial longitudinal groove in M. longwangshana  ).

Comments. Type material could not be directly examined, but images of the holotype taken by Dr. Tang Pu (ZUH) were used to compare with the new species described in this paper.
