Viraktamath, C. A. & Anantha Murthy, H. V., 2014, Review of the genera Hishimonus Ishihara and Litura Knight (Hemiptera: Cicadellidae) from the Indian subcontinent with description of new species, Zootaxa 3785 (2), pp. 101-138 : 117

Hishimonus zeylanicus sp. nov.

Figs 34–35 , 217–223 .

Coloration as in H. distinctus . Paler specimens lack fascia on legs. Darker specimens with subapical spot on anterior surface of profemora and apical and basal spot on posterior surface, mid femora with two bands on subapical region and bases of setae, dark brown.

Male genitalia. Pygofer in lateral view longer than its height, posterior margin broadly rounded, macrosetae confined to posterior submargin; valve with broadly rounded posterior margin. Subgenital plate with posterior fingerlike process 0.33 times total length, lateral margin convex. Style 2.5 times as long as wide at base, with rather straight apophysis, subapical lobe well defined. Connective with stem shorter than arms. Aedeagus with basal processes arising almost on well developed dorsal apodeme, directed dorsally and remote from shaft in lateral view, 0.33 length of aedeagal shaft; each shaft divergent in basal half and then convergent, in posterior view, broad at base then tapered, inwardly curved in distal 0.33 length; in lateral view shaft tapered and abruptly narrowed and filamentous beyond gonopore and directed dorsally; gonopore subapical.

Measurements. Male 3.50 mm long and 1.20 mm wide across eyes.

Material examined. HOLOTYPE ♂, SRI LANKA: Anu Dist., Hunuwilagama near Wilpattu 200 feet [61 m], Black light, 28.x–3.xi.1976, collected by Heavel, G.F., Dietz IV, R.E., Karunaratne, S. and Balasooriya, D.W. ( USNM).

Etymology. The species name alludes to the country in which the holotype was collected.

Remarks. H. zeylanicus resembles H. pronus in the male genitalia characters, but differs in the shape of the aedeagal shafts and the basal processes. In H. zeylanicus the shafts are very broad at the base and inwardly curved at distal 0.33 length whereas in H. pronus the shafts are uniform in width and not so curved in posterior view, but in lateral view the shafts in H. pronus are strongly sinuate which is not the case in H. zeylanicus .
