TAXONOMIC STUDY ON GENUS ACROCLISOIDES GIRAULT and DODD FROM CHINA (HYMENOPTERA:PTEROMALIDAE)

In the present paper,a new species Acroclisoides quintus sp.nov.is described, Acroclisoides sinicus (Huang Liao) is combined from Neocoruna ,and two species, Acroclisoides luzonensis Gahan、 Acroclisoides indicus Ferriere,are newly recorded from China.The type specimens are deposited in Institute of Zoology,the Chinese Academy of Sciences.1 Acroclisoides quintus sp.nov. (Figs.1 2) Female.Length 2 mm.Metallic dark green;antennae yellowish except 4 5 funicular segments and 1 2 clava segments pale brownish;legs yellowish;forewing hyaline. Head in front view (Fig.1),clypeus large and lower margin truncate;space between eyes 4 times as long as eyes height,4 times as long as malar space.Antennal insertion above center of face;scape long,about 1/2 length beyond the vertex;pedicellus shorter than the first funicular segment;every funiclar segment longer than broad(3∶2);clava 2 times as long as broad.Head in dorsal view,eye length 2 times as long as temple;POL:OOL as 6∶7.Relative measurements:head width 52,height 30,dorsal length 22.Head in lateral view (Fig.2),gena slightly hollow,but without tooth like projection. Thorax convex.Pronotum with distinct collar and collum,and collar weakly margined;pronotum about 1/5 length of mesoscutum.Mesoscutum length shorter than its width (22:36);notauli weak but complete.Scutellum with frenal line.Propodeum with weak median carina,plicae absent;nucha distinct.Fore with (Fig.3) speculum very small;basal vein and basal cell pilose;lower margin of basal cell closed.Relative measurements:marginal vein 15,postmarginal vein 23,stigmal vein 14. Petiole as long as broad.Gaster about 2 times as long as broad (48∶25);the first tergite slender and elongate,petiole like,about 1/3 length of whole gaster. Male:unknown.
