Viraktamath, C. A. & Gnaneswaran, R., 2009, Three new species of Goniagnathus (Hemiptera: Cicadellidae) from the Indian subcontinent with description of a new subgenus, Zootaxa 2224 (1), pp. 51-59 : 54-57

Goniagnathus (Tropicognathus) anufrievi sp. nov.

Figs 1, 2 , 7–12 .

Brown with dark brown markings. A transverse submarginal stripe slightly interrupted in middle and near ocelli dark brown; a median and a lateral ill defined spots flush with transverse stripe dark fuscous. Anterior margin of head cream yellow; short stripe between ocellus and eye solid dark brown; fronto-clypeus with transverse dark brown stripes; antennal pit, area below compound eyes, median spot on clypellus, lateral margin of genae, and oblique spot on upper extremity of lorum dark brown. Pronoutm brown, mottled with pale brown spots. Scutellum with brown and dark brown markings. Forewings brown, venation dark brown richly mottled with pale brown. Coxae dark fuscous, fore-femora with dark fuscous spots alternated with pale brown, femora with dark fuscous patches, bases of hind tibial spines dark fuscous. Female paler than male especially on dorsal aspect, transverse stripe on head solid, not interrupted by pale spots.

Head slightly longer medially than next to eyes; pronotum flat with transverse rugae.

Male genitalia: Pygophore gradually narrowed and conically rounded at caudal region, with dorsal appendage broader at anterior region, with strongly sinuate ventral margin, caudal 0.33 comparately narrower and pointed; anterior apodeme present at dorsal 0.33 portion of anterior margin, bilobed. Fused subgenital plate and valve caudally rounded. Style with strongly bilobed apophysis, inner lobe longer than outer one. Aedeagus simple, with well developed dorsal apodeme and preatrium, shaft arcuate, narrow caudally, gonopore apical, with recurved hook-like short appendage laterally.

Female: Seventh sternite broader than long, caudo-lateral angles prominent, hind margin medially convexly produced with a median notch.

Measurements: Male 4.6 mm long, 2.0 mm wide across eyes; female 6.5 mm long, 2.6 mm wide across eyes.

Material examined: Holotype male INDIA: Karnataka: Gundlupet , 3.vii.2008, Nagaraj, T. ( UASB) . Paratype: 1 female data as for holotype ( IARI)

Remarks: The male is distinctly shorter than the female. G. anufrievi resembles G. appellans in the shape of the fused subgenital plate but differs in having a broad base to the pygophore appendage and shorter apical curved processes of the aedeagal shaft.

Etymology: This species is named after Dr G. A. Anufriev a renowned Auchenorrhycha worker, for his help in deciphering the species of Goniagnathus from the Indian subcontinent.
