Shobharani, M., Viraktamath, C. A. & Webb, M. D., 2018, Review of the leafhopper genus Penthimia Germar (Hemiptera: Cicadellidae: Deltocephalinae) from the Indian subcontinent with description of seven new species, Zootaxa 4369 (1), pp. 1-45 : 16-17

Penthimia ribhoi sp. nov.

Figs 31–32 , 51, 157–163.

Head, pronotum and scutellum shiny black. Scutellum touched with two lateral spots and one apical spot, yellow. Forewings black with orange-brown spots.

Male genitalia. Pygofer with dorsoposterior angle prominent, dorsal margin almost straight, ventroposterior margin convex, covered with micro and short macrosetae. Valve large, triangular with slightly rounded posterior angle. Subgenital plate with basal 1/3 straight, then inwardly curved, with only microsetae, devoid of macrosetae. Connective Y-shaped. Style with short fingerlike apical apophysis slightly curved laterally, subapical lobe well developed. Aedeagus short, robust, strongly curved, dorsal apodeme well developed, short, ventral margin angularly curved at mid length, shaft depressed in distal 0.33, with large gonopore, dorsal margin with two lateral rim-like edges visible in lateral view.

Length. Male 4.0– 4.3mm

Material examined. INDIA: Meghalaya: Holotype ♂, Ri-Bhoi: ICAR RC NEH, Barapani , 1031m, 25o41’N, 0 91o55’E, 22.ix.2013, at light, Yeshwanth H.M. ( UASB) . Paratypes: 1♂ same data as holotype ; 3♂ same data as holotype except 24.ix.2013, sweep net ; 1♂, East Khasi Hills, Upper Shillong , 1686 m, 25o32’N, 0 91o48’E, 22.ix.2013, Yeshwanth H.M. ( UASB) .

Etymology. The species name alludes to the district Ri-Bhoi of Meghalay from where it has been collected. It is a noun in apposition.

Remarks. Externally this species is similar to P. ereba in coloration and structure but has entirely different male genitalia. It resembles P. neoattenuata in male genitalia especially in the shape of the subgenital plates and the aedeagus but differs in lacking the dorsal keel on the aedeagal shaft found in P. neoattenuata and has dorsolateral margins of the aedeagal shaft rimlike visible in lateral view. Some specimens also have been collected in a yellow pan trap.
