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 : 110-111

Hishimonus dwipae sp. nov.

Figs 13–14 , 94 –99.

Head, pronotum and scutellum lemon yellow, spot on either side of median line on posterior margin of crown, median carina fuscous. Forewings ivory white with a few brown mottling between veins; median spot well defined, pale brown with dark brown, narrow, discontinuous anterior margin, posterior margin with dark brown spot at wing margin. Legs pale ochraceous, bases of setae dark brown.

Male genitalia. Pygofer in lateral view longer than its height, posterior margin conically rounded, macrosetae confined to posterior half; valve with broadly triangular posterior margin strongly medially angled, about twice as broad at base as long medially. Subgenital plate with well defined posterior fingerlike process, 0.40 times as long as the total length of the plate, lateral margin less strongly convex. Style three times as long as wide at base, with rather straight apophysis, subapical lobe well defined. Connective with stem shorter than arms. Aedeagus with pair of basal processes to shafts diverging from each other from base and about 0.20 length of shaft, not projecting beyond curvature of the shaft posteriorly; dorsal apodeme well developed; each shaft divergent from base in posterior view, broadened distally, slightly before level of gonopore and then tapered, thus forming triangular lobe enclosing gonopore; in lateral view, anterior margin triangularly expanded lamellate lobe at level of gonopore and rather straight beyond subapical gonopore.

Measurements. Male 3.3 mm long and 1.1 mm wide across eyes.

Material examined. HOLOTYPE ♂, SRI LANKA: Pol. Dist., 10 mi [16 Km] E Habarana, black light, 650 ft. [192.3 m], 12.xi.1976, collected by Havel, G.F., Dietz IV, R.E., Karunaratne, S. and Balasooriya, G.W. ( USNM).

Etymology. The species name (Sankrit: Dwipa meaning Island) alludes to the insular distribution of the species.

Remarks. H. dwipae sp. nov. is very similar to H. pronus Knight from Solomon Islands but differs in the shape of the apices of the aedeagal shafts. Each aedeagal shaft, in lateral view, has a triangular expansion which is not the case in H. pronus and also the shaft is strongly sinuate in H. pronus compared to that in H. dwipae .
