Nandigallia matai sp. nov.

Figs 472–481.

Color. Ochraceous. Two spots on vertex, antennal cavities, anterior portions of pronotum, most of scutellum, facial sulci, claval cells and veins of corium, fuscous. Median stripe on vertex continuing on face, brownish. Legs ochraceous but annulated with brown. Abdomen ochraceous. Claval veins, anterior portions of claval suture and parts of vein M stamineous; cells of corium hyaline.

Morphology. Small robust species. Vertex longer medially than next to eyes with two tubercles closer to eyes than to each other. Clypellus more or less parallel sided, apically slightly emarginated. Lateral arms of epicranial sulcus evident below ocelli. Face, vertex, pronotum, scutellum and forewings coarsely granulated. Pronotal disc nearly flat, anterior margin convex, posterior almost straight, with transverse shallow depression, lateral areas of depression transformed into shallow cavities. Scutellum transversely impressed in middle and with two shallow rounded depressions anterior to impressed line. Forewings with prominent venation and sparsely clothed with fine seta. Hind wings shorter than forewings. Sternal apodemes at base of abdomen well developed and sclerotized.

Male genitalia. Subgenital plates quadrate fused basally, inner margins straight, outer margins curved caudally. Styles twisted caudally, outer arm stout, shorter than inner arm. Connective flat, broader proximally, abruptly narrowed about 0.33 caudally, distal margin strongly sinuate, anterior margin concave. Aedeagus with preatrium strongly developed, longer than dorsal apodeme, shaft bulbous at base, curved dorsad narrowed distally, terminated by one pair of short curved processes on either side of apical gonopore. Anal collar process twisted, with fingerlike process, surface uneven.

Measurements. Male 3.3 mm long, 1.4 mm wide across eyes.

Material examined. S. CHINA: HOLOTYPE ♂, Fukien: Kienyang city, 9.vii.1940, T.C. Ma ( BPBM) . Paratype: 1 ♂, INDIA: West Bengal: Siliguri , 31.x.1981, S. Viraktamath ( UASB) .

Remarks. N. matai closely resembles N. nandiensis sp. nov. (see below) but differs in the structure of the male genitalia as given in the key. The twisted anal collar process is a unique character of this species.
