Taperus luchunensis, Zhang, Xinmin, Zhang, Yalin & Wei, Cong, 2010

Zhang, Xinmin, Zhang, Yalin & Wei, Cong, 2010, Review of the leafhopper genus Taperus Li & Wang (Hemiptera: Cicadellidae: Evacanthinae) from China, with description of three new species, Zootaxa 2721, pp. 39-46 : 45-46

Taperus luchunensis sp. n.

( Figs 5, 10, 15, 20 , 41–45 , 54 )

Measurements. ɗ: body length: 6.0 mm; head width (incl. eyes): 1.2 mm; head length: 0.7 mm.

Vertex, pronotum and scutellum ( Figs 5, 20 ) yellowish brown, with oyster white longitudinal band distinct only on apex of vertex medially. Forewing ( Fig. 54 ) light brown, with nearly white and transparent plaque in middle of costal area.

Male pygofer ( Fig. 41 ) broad at base, distinctly narrowed apically; posterior margin with macrosetae short. Apex of footlike apical process of style short and robust, about one six length of style ( Fig. 44 ). Aedeagal shaft ( Figs 42–43 ) with lateral lamellate processes well developed but apex very short.

Etymology. The name of this species is derived from the locality of the holotype.

Material examined. Holotype ɗ ( IZAS), China, Yunnan Prov.: Luchun County, 1900m, 30-April-1982, coll. Jin Gentao.

Distribution. China (Yunnan).

Remarks. This new species can be readily recognized by its yellowish brown body color and the well developed lateral lamellate processes of the aedeagus.

The following three species formerly placed in Taperus are transferred to Convexana Li, 1994 .

Convexana bimaculatus (Cai & Shen) , comb. n. Taperus bimaculatus Cai & Shen, 1997: 250 , Fig. 4 Distribution. China (Henan).

Convexana discolor (Cai & Shen) , comb. n. Taperus discolor Cai & Shen, 1999: 27 , Fig. 4 Distribution. China (Henan).

Convexana lanpingensis (Li & Wang) , comb. n. Taperus lanpingensis Li & Wang, 2001: 389 , Fig. 3 Distribution. China (Yunnan).

Remarks. The above three species are transferred from Taperus to the genus Convexana because they are more similar to species of the latter. These two similar genera differ in the location of the ocelli, the setae of the male pygofer, and the shape of the aedeagus, as follows. In Taperus , the ocelli are located on the lateral margin of the vertex, closer to the eye than to the apex; the male pygofer has numerous macrosetae marginally; the aedeagus has the lateral lamellate processes broad and rounded (not triangular) in lateral view, and the shaft curved dorsal in lateral view. In contrast, the ocelli of Convexana are located between the lateral margin and the corresponding lateral carina, about equidistant from the corresponding eye and the apex of the vertex; the male pygofer lacks spine-like macrosetae; and the aedeagal shaft has the basal part of the lateral lamellate processes well developed anteriorly and attenuated apically, triangular in lateral view.
