Japanagallia viraktamathi sp. nov.

( Figs 31–39 ; 56)

Body length (including tegmina). ♂, 3.9 mm.

Holotype description.

Head and thorax (color). Ground color black. Face yellowish brown, dorsal margin with two black oval maculae contiguous to crown, and with black band at middle gradually broadened downward; ocelli red tinged, lateroventral areas of ocelli with black spots; distal half of frontoclypeus evenly black, fused with middle black band; large black markings below each antennal fossa; anteclypeus and lora completely black. Pronotum with distinctive lemon yellow band on posterior margin. Scutellum with lateral yellow. Forewings with basal small part, claval suture and distal claval veins yellow. Legs yellow. Color pattern of remaining parts similar to Japanagallia hamata Zhang & Li.

Morphology. Body similar as J. gracilenta sp. nov.

Male genitalia: Pygofer ( Fig. 34 ), in lateral view, broad basally, dorsal margin concave medially, caudal margin truncate and angulate, with serrate processes ( Fig. 35 ) dorsally directed. Valve nearly trapezoidal, front margin slightly concave medially, wider than hind margin, lateral and hind margins approximately straight. Subgenital plates ( Fig. 34 ) short, triangular in ventral view, not fused to each other on basal part, scattered with few setae. Style ( Fig. 36 ), straight, apex slightly inflated, with small tabular process; inner arm slender and short, apex truncate and slightly expanded, with small digital spine-like process. Connective ( Fig. 37 ), with anterior margin slightly narrower than posterior margin, lateral margins clearly excavated, posterior margin rounded and excavated medially. Aedeagus ( Figs 38–39 ), in lateral view, with dorsal apodeme strongly developed, tumid, dorsal margin angulate, with small spines, basal margin elongated; shaft slender, bend dorsally, bearing short and laterally furcated ventral process basally, excavated basally; dorsal margin with pair of small spinelike processes directed dorsally at subapical part, ventral margin with pair of long processes pointed apically on sub basal area; in ventral view, shaft broad basally, with paralleled apical half margins, apex rounded; gonopore on ventral margin small and apical. Segment X ( Fig. 34 ) sclerotized, S-shaped.

Female genitalia. Unknown.

Material examined. Holotype: ♂, CHINA: Guangxi Autonomous Region, Longsheng County, Huaping National Natural Reserve, 26. IV. 2012, collected by Zheng Weibin.

Distribution. China (Guangxi Autonomous Region).

Remarks. Japanagallia viraktamathi sp. nov. is similar to J. dentata Cai & He , in having the caudal margin of the pygofer serrated, but can be distinguished from latter by the dorsally directed aedeagal shaft with a pair of small spines directed ventrally at the subapical dorsal margin, pair of elongate, slightly curved processes directed anteriorly on the basal outer margin, and a tumid dorsal apodeme with small spines; the new species is also similar to J. gracilenta sp. nov. (see above) and J. spinosa Zhang in color pattern, but can be distinguished from the first by the shorter ventral process on the base of the aedeagal shaft, and the paired subapical small spines; and from the latter by the absence of apical paired processes, and presence of spines on the dorsal apodeme. Also, it may be distinguished from J. curvipenis Viraktamath et al. by the two pairs of processes of the aedeagal shaft.

Etymology. The species is named in honor of Dr. Chandra A. Viraktamath (Department of Entomology, University of Agricultural Sciences, India) for his excellent contributions to leafhopper taxonomy and invaluable help to the first author.
