Genus Nandigallia nov.

Type-species: Nandigallia nandiensis sp. nov.

Morphology. Macropterous or brachypterous. Head slightly longer in middle than next to eyes, wider than pronoutm. Ocelli closer to each other than to adjacent eyes, on upper part of face, often visible from above. Face wider than long, transclypeal sulcus incomplete, gena sinuate below eyes, clypellus exceeding genal curve. Pronotum, flat, either smooth or with transverse rugae, hind margin straight. Scutellum shorter than pronotum. Forewings with three anteapical and four apical cells, inner anteapical cell closed behind and often subdivided ( Figs 473, 487), claval veins separate. Fore femur intercalary setae arranged in arcuate row, two seate of row AV stout and elongate ( Fig. 31). Hind tibial macrosetae PD 8±1, AD 7±1, AV 6±1; PV with capitate setae but with a few stout setae alternated with 2–4 slender, smaller setae as in Hemagallia . Hind basitarsus with two platellae on distal transverse row.

Male genitalia. Pygofer rounded caudally without processes. Subgenital plates as in Hemagallia . Styles short, broad, with broad inner arm, longer than outer arm. Aedeagus with well developed dorsal apodeme and preatrium, shaft with apical or subapical, short processes, gonopore apical. Anal collar process well developed.

Female genitalia. First pair of valvulae arcuate, sculptured area occupying more than half length, sculpture constisting of irregularly arranged oval alveolii, subapical in midsection ( Figs 80, 81). Second pair of valvulae arcuate, with denticular area confined to distal 0.25 length, teeth simple, ventroapical area crenulate ( Fig. 83).

Remarks. This genus closely resembles Hemagallia but differs in the structure of the aedeagus and styles. Both genera have a rather long inner arm of the style which is slightly broadened in Hemagallia , whereas it is much broader and lamellate in Nandigallia . In the two species of Hemagallia , the aedeagus is more or less uniform without a preatrium, whereas in Nandigallia , it is swollen basally with its narrowed apex having a short apical processes and the preatrium is well developed though short. In some respects Nandigallia also resembles the New World Bergallia Oman but differs in not having a spine like projection on the caudal lobe of the pygofer.
