Genus Japanagallia Ishihara  

Japanagallia Ishihara, 1955   : 215,217. Type-species: Agallia pteridis Matsumura   , by original designation.

Color. Sexually dimorphic leafhoppers. Male black with yellow or ochraceous areas on face, vertex, pronotum and scutellum. Female brownish and larger.

Morphology. Medium sized leafhoppers, measuring 4.0–6.0 mm long. Head wider than pronotum. Vertex distinctly narrower in middle than next to eyes, upturned in middle, sinuately curved laterally behind eyes. Face finely granulose, transclypeal sulcus incomplete in the middle or complete, clypellus extending beyond genae, about as broad at apex as at base. Ocelli closer to eyes than to each other. Pronotum finely granulate, transversely weakly wrinkled. Scutellum broad at base, finely granulose. Forewing venation often obsolete except basally and on clavus; three anteapical and four apical cells, inner anteapical cell closed posteriorly, claval veins joined by one or more cross veins ( Fig. 19). Fore femur with intercalary setae arranged in oblique row, setae on row AV not enlarged ( Fig. 30). Hind tibial macrosetae PD 8±2 (7–12), AD 7±1, AV 6±1 macrosetae. Hind basitarsus with two platellae on distal transverse row.

Male genitalia. pygofer with short mesal or caudo-dorsal process, with or without denticles or often with short, stout setae. Styles with inner arm longer than outer arm. Connective variable in shape, usually long, pigmented ( Figs 402, 410). Aedeagus variable, often with strongly developed preatrium and dorsal apodeme with or without processes. Aedeagal shaft symmetrical with processes. Anal collar process simple, not elaborate.

Female genitalia. First pair of valvulae alveolate, with rather elongate oval closely packed alveoli in vertical or oblique rows with space between each row, sculptured area on 0.75 length ( Figs 76, 77). Second pair of valvulae with subapical triangular projection on dorsal margin, teeth becoming more prominent near apex, without denticles, ventroapical margin serrated ( Figs 78, 79).

Distribution. India (Himalayan region), Nepal, Burma, Southern China, Indonesia (Java, Sumatra), Malaysia (Northern Borneo), Taiwan, Japan.

Remarks. Oman (1970) discussed the relationship of this genus with some members of Agalliopsis Kirkaldy   and opined that it resembles some members of Agalliopsis (Agallaria) Oman   in general shape and in having the posterior margin of the crown slightly sinuate laterally. Japanagallia   has the tenth segment only weakly developed in the male, the pygofer often has a pair of posteriorly directed pointed lobes next to the anal tube, and the aedeagus is stout with a large basal atrium. Japanagallia   closely resembles Agalliopsis   and Igerna   . It differs from these by the presence of a cross vein between the claval veins, the vertex being vertical in the middle and by the structure of the male genitalia in which the pygofer has caudodorsal processes and both preatrium and dorsal apodemes are not only well developed (at least one of them) but also bear processes.
