Japanagallia hamata Zhang & Li, 1999 , 21 (2): 107, Figs 1 – 6 .

Body length (including tegmina). ♂, 3.5 – 3.7 mm; ♀, 3.8 – 4.0 mm.

Holotype description.

Head and thorax (color). Ground color black. Head yellowish brown, vertex with small black longitudinal band medially, two symmetrical black maculae placed on either side of it and visible in facial view. Face black excepting areas surroundings eyes, antennal fossa, lateral margins of genae dark brown; eyes dark brown; antennae yellowish brown; beak yellowish. Pronotum black, both lateral margins and both sides of hind margin slightly yellowish brown. Scutellum black. Forewings except for basal area yellowish black, with slightly indistinctive yellowish brown tinge on distal half portion and posterior margins on claval region; venations slightly darker than surroundings excepting lighter claval suture. Legs yellowish brown, with dark maculae.

Morphology. Body ( Figs 9–10 ) slender. Face ( Fig. 11 ), with lateral margins of genae rounded medially. Claval veins connected at least by one, up to three cross veins.

Male genitalia: Pygofer ( Fig. 12 ), in lateral view, deltoid, broad basally, dorsoposterior margin truncate, caudal margin sub oblong and with a few scattered setae, ventrocaudal margin slightly excavated. Valve ( Fig. 13 ), and subgenital plates ( Fig. 13 ), in ventral view, similar to J. gracilenta sp. nov.. Style ( Fig. 14 ), in dorsal view, slender, apex of stem produced into semitransparent process and half apex of stem with small setae, inner arm short, apex of inner arm truncate and bearing digital process. Connective ( Fig. 15 ), in dorsal view, lageniform. Aedeagus ( Figs 16–17 ), in lateral view, L-shaped, with dorsal apodeme and angulate preatrium well developed; shaft directed ventrally; near base with spine-like process pointed dorsally on dorsal margin, and near apex produced into pair of long processes twisted ventrally on lateral margins; apex elongate and tapered to point, reflexed, formed as hook shaped; in dorsal view, shaft clearly inflated in middle, gonopore apical on dorsal margin.

Female genitalia. Seventh sternite wider than long, hind margin excavated medially, and bearing medial protuberance, both lateroposterior corners nearly rounded, ovipositor clearly exceeding beyond pygofer. First valvulae ( Fig. 18 ), in lateral view, dorsally curved from base; ventral interlocking device on basiventral portion of shaft clear; dorsolateral surface with reticulate sculptured area formed by oblique rows of scalelike processes ( Fig. 19 ) on distal 2/3 of shaft; ventroapical region with scalelike processes; dorsoapical and ventroapical margins pseudodentate; apex acute ( Fig. 19 ). Second valvulae ( Fig. 20 ), in lateral view, curved dorsally from base, withbroadest region at apical fourth; dorsal hyaline area present, nearly median portion; dorsal prominence heavily pronounced; teeth on apical half of dorsal margin, positioned behind dorsal hyaline area, not very uniform, mostly subtriangular, not bearing denticles ( Fig. 20 ), larger in size basally than distally ( Fig. 20 ); apex blunt ( Fig. 20 ). Gonoplacs, in lateral view, shoelike, with basal half narrow and nearly paralleled between dorsal and ventral margins, dorsal margin suddenly broadened on apical 2/5 and then narrowing gradually toward rounded apex; surface with tiny spiniform processes and several setae along ventral margin.

Material examined. 1 ♂ [Holotype], CHINA: Guizhou Province, Libo County, Laya, 13. V. 1995, collected by Chen Xiangsheng; 9 ♀♀ [Paratypes], same data as above; 1 ♂, 2 ♀♀, CHINA: Guizhou Province, Wangmo County, Lekuan, 21–23. IV. 2009, collected by Dai Renhuai (n=1), Song Qiongzhang (n=1) and Zhang Zhengguang (n=1); 1 ♀, CHINA: Guizhou Province, Suiyang County, Kuankuoshui National Natural Reserve, 0 7. VI. 2010, collected by Li Hu; 1 ♀, CHINA: Guangxi Autonomous Region, Wuming County, Damingshan National Natural Reserve, 15. V. 2011, collected by Yu Xiaofei; 2 ♂♂, same locality, 16. IV. 2012, collected by Zheng Weibin; 1 ♂, 8 ♀♀, CHINA: Guizhou Province, Wangmo County, 22. VIII. 2012, collected by Long Jiankun (n=7) and Chang Zhimin (n=1).

Distribution. China (Guizhou Province, and Guangxi Autonomous Region).

Remarks. Japanagallia hamata Zhang & Li is redescribed and illustrated here (originally described in Chinese) based on examination of the holotype and material collected recently. Viraktamath, et al. (2012) also redescribed this species, without examination of the holotype. The comparison between the holotype and their illustrations, proved it to be a misidentification. The species identified as J. hamata by Viraktamath, et al. (2012) is actually a new species, J. neohamata sp. nov., described below. This conclusion was verified by Dr. Chandra A. Viraktamath (pers. comm.; Department of Entomology, University of Agricultural Sciences, India). Japanagallia hamata Zhang & Li is similar to J. multispina Viraktamath and can be distinguished from the latter by the pair of long subapical processes of the aedeagal shaft twisted ventrally on the lateral margins.
