Scaphoideus rostratus, Chen, Fangying, Dai, Wu & Zhang, Yalin, 2015

Chen, Fangying, Dai, Wu & Zhang, Yalin, 2015, Review of species of the Scaphoideus albovittatus group (Hemiptera, Cicadellidae, Deltocephalinae) from China, with a checklist and distribution summary for Chinese species in the genus, Zootaxa 3904 (3), pp. 334-358 : 344

Scaphoideus rostratus sp.nov.

( Figs. 1 E, J, O, 3B, 8A–G)

Coloration and structure ( Figs. 1 E, J, O, 3B) similar to those of albovittatus Matsumura , but slightly lighter in colour. Head narrower than pronotum, triangularly produced in front, bluntly angled, longer than inter-ocular width ( Figs. 1 E, 3B). Forewing with three reflexed veins, none basad of outer anteapical cell ( Fig. 1 E, J).

Male genitalia. Pygofer in lateral aspect tapering posteriorly, with dorsal margin straight and ventral margin convexly rounded, with two subapical tufts of long setae in addition to scattered short setae ( Fig. 8 A, B). Valve semicircular. Subgenital plate triangular and broad basally, with single basal macroseta in addition to few hairlike setae ( Fig. 8 C). Style with anterior part broad, preapical lobe not developed, apical process strongly laterally curved and tapered to acute apex ( Fig. 8 C, D). Connective Y-shaped, arm well developed longer than stem; posterior processes in dorsal aspect of uniform width in basal half, triangularly widened before apex (apex broken in holotype and shape unknown) gradually narrowed to apex; in lateral aspect bent dorsally at base, then curved and directed ventad ( Fig. 8 C, E). Aedeagus with well developed dorsal apodeme, shaft robust and short, strongly compressed, with apex tapered and curved dorsally, gonopore apical on ventral surface ( Fig. 8 F, G).

Measurements. Male 5.4mm long, 1.1mm wide across eyes.

Etymology. The specific epithet ‘ rostratus ’ refers to the shape of apex of the aedeagal shaft from lateral view in this species.

Material examined. 1♂, Yunnan Prov., Jiangcheng, 25April 1982, Jin Gentao (SEM).

Remarks. The new species is similar to S. albovittatus , but can be differentiated from the latter by the pygofer side short, 1.5 times as high as long (state length in S. albovittatus for comparison); aedeagal shaft strongly compressed and the width being 2/3 of the length (state length in S. albovittatus ). The apices of the connective processes and one of the subgenital plates are broken near the tip in the holotype male.
