Genus Ianagallia nov.

Type-species: Austroagallia bifurcata Sawai Sing and Gill

Color. Ochraceous to brown, two large round black spots on vertex closer to eyes than to each other, two larger spots on posterior half of pronoutm dark brown to black.

Morphology. Small leafhoppers measuring 3–4 mm in length. Vertex comparatively broad, hind margin sinuately curved behind eyes. Ocelli closer to each other than to eyes. Face slightly wider than long. Pronotum arcuate, more than half as long as wide, finely punctured, hind margin straight. Scutellum about 0.66 length of pronotum. Forewings with 3 anteapical and 4 apical cells, inner anteapical cell open posteriorly, claval veins not joined by cross vein ( Fig. 18). Forefemur with intercallary setae not arranged in arcuate row, setae on row AV not thickened ( Fig. 29). Hind femoral macrosetae 2+1. Arrangement of macrosetae on hind tibia PD 5±1, AD 6, AV 5±1. Hind basitarsus with two rows of spine-like setae on plantar surface and one platella on distal transverse row ( Fig. 34). Sternal apodemes at base of male abdomen well developed.

Male genitalia. Pygofer apically rounded, with an internal dorsocaudal triangular lobe. Subgenital plates without long, stout setae. Styles apically forked, inner arm shorter than outer arm. Connective slightly longer than broad, apically slightly excavated. Aedeagus very robust, asymmetrical, dorsal apodeme strongly developed, robust, longer than shaft, aedeagal shaft slender, bearing bifurcate process, ventral process long, apically asymmetrically forked, longer than shaft. Anal collar divided into two sclerites, ventral one heavily sclerotized, anteriorly apically broadened and plate-like, dorsal one apically pointed.

Female genitalia. Similar to that in Austroagallia ( Figs 73–75).

Distribution. China, India, Thailand.

Remarks. Ianagallia is related to Austroagallia and Igerna , and differs in the well developed, asymmetrically bifurcate, preatrial process of the aedeagus, slender and shorter aedeagal shaft and the intercalary row of setae on forefemora not arranged in an arcuate row.
