( Plate 99C )

Adryinus jini Xu & Yang in Xu et al. 1995 (June): 119; He & Xu 2002: 298.

Adryinus platycornis Xu & He 1995a (December) : 307; type locality: Guangzhou (Guangdong, China); He & Xu 2002: 299; syn. nov.

Description of Female. Fully winged; length 7.2–8.1 mm. Head black, except mandible partly brown-reddish and lateral areas of clypeus yellow; antenna black, except segments 9–10 testaceous and ventral side of segment 1 whitish; mesosoma and metasoma black; legs black. Antenna weakly clavate; antennal segments in following proportions: 9.7:4:23:13.5:12:8:5.2:4.5:3.5:5.5; in holotype of A. jini , antennal segment 10 cylindrical (in holotype of A. platycornis , both last antennal segments broken, not flat as in original description). Head excavated, shiny, granulated and with some longitudinal keels (more numerous in holotype of A. platycornis ); occiput granulated; frontal line complete; occipital carina incomplete, present only behind and shortly on sides of posterior ocelli, laterally almost reaching 0.5 length of OOL; POL = 1.6; OL = 1.6; OOL = 8.5; OPL = 0.2 (posterior ocelli touching occipital carina in holotype of A. platycornis ); greatest breadth of posterior ocelli longer than OPL (1.5:0.2); temple distinct. Palpal formula 6/3. Pronotum crossed by strong transverse impression, dull, granulated and sculptured by numerous keels around disc and anterior collar; posterior edges of pronotum rounded, not produced into lobes. Scutum dull, granulated. Notauli hardly visible, incomplete, reaching about 0.5 length of scutum. Scutellum dull, granulated and reticulate rugose. Metanotum short, granulated and reticulate rugose. Propodeum with dorsal surface longer than posterior surface (11:6.5); dorsal surface reticulate rugose and sculptured by some parallel and longitudinal keels; posterior surface reticulate rugose, with two longitudinal keels. Mesopleuron and metapleuron dull and reticulate rugose. Fore wing with two dark transverse bands; distal part of stigmal vein much longer than proximal part (11.5:5); marginal cell open. Protrochanter more than four times as long as broad (23:5). Protarsal segments in following proportions: 17.5:2:5.2:12:19.5. Segment 3 of protarsus produced into hook. Enlarged claw ( Plate 99C ) with one subapical tooth and one row of eight–nine bristles. Segment 5 of protarsus ( Plate 99C ) with two rows of 29–36 lamellae; distal apex with 18–42 lamellae. Tibial spurs 1/0/1.

Male. Unknown.

Material examined. Types: ♀ holotype of A. jini : CHINA: Guangxi, Nanning , 108°03'N 22°08'E, orange orchard, Shaolong Yang leg. ( ZJUC) ; ♀ holotype of A. platycornis : CHINA: Guangdong, Guangzhou , 5.V.1979, Chuanchuan Lu leg. ( ZJUC) .

Hosts. Unknown.

Distribution. China (Guangxi, Guangdong).

Remarks. The hind tibia has one very long tibial spur and one tuft of bristles, among which one bristle is larger than others; it is not a second spur; for this reason, this species is included in Adryinus and not in Neodryinus . A. platycornis is here considered junior synonym of A. jini , following the comparison of the types of both species. The small differences between the two holotypes do not justify the creation of two separate species.
