Body impunctate. Malar space linear, postocellar area 2 times broader than long, lateral furrows straight and divergent backwards. Anal cell in hind wing petiolate. Male and female genitalia as shown in Fig.1. This new species is closely allied to Nesoselandria javana (Enslin) but differs from it in dorsal parts of scape and pedicellum blackish brown, tergites 2~6 with distinct middle triangular pale spots, harpes short, gonolacinia narrower and volcella with a small caudal process.Holotype: ♀, paratypes: 6♀♀1♂, Shiwandashan Forest Park, Guangxi, China, Feb. 25, 2002.

Antenna not compressed with the third segment slightly longer than the fourth one. Prepectal furrow fine. Claw with basal lobe, inner tooth shorter than outer tooth. Sheath very narrow in dorsal view. Apical half of lancet as shown in Fig. 2.This new species is a member of nipponicus group of the genus and differs from other known species of the group in tegula entirely white, each femur with a broad yellow ring at apex, middle fovea transverse and sheath very narrow in dorsal view.Holotype: ♀, Shiwandashan Forest Park, Guangxi, China, Feb. 25,2002.Huang Ningting (Central South Forestry University). Heptamelus foveatus Wei sp. nov.

Wing subhyaline. Mesopleuron with large and sparse punctures, posttergite with a few punctures, body otherwise impunctate. Malar space linear, clypeus about 2 times broader than long with distinct lateral teeth; middle fovea quite large and deep, lateral fovea indistinct; postocellar area broader than long with divergent lateral furrows. Vein R+M shorter than 1m-cu; petiole of hind anal cell about as long as cua, cell Rs small and cell M larger than cell 2Rs of front wing. Genitalia as shown in Fig. 3.Holotype: ♂, Shiwandashan Forest Park, Guangxi, China, Feb. 16,2002.Huang Ningting (Central South Forestry University). Niasnoca nigroflagella Wei sp. nov.
