Song, Yuehua & Li, Zizhong, 2011, First report on the leafhopper genus Takama Dworakowska & Viraktamath (Hemiptera: Cicadellidae: Typhlocybinae) from Hainan Island, China, with the description of two new species, Zootaxa 3127, pp. 64-68 : 66

Takama jianfenga Song & Li sp. nov.

( Figs. 11–17 )

External appearance as in T. horna sp. nov., but brownish patches on vertex not visible and colour rather light yellowish ( Fig. 11 ).

Abdominal apodemes ( Fig. 12 ) short, extended dorsomesad, nearly reaching fourth sternite.

Male genitalia: Pygofer dorsal appendage ( Fig. 13 ) long and slender, curved acutely, tapering towards apex. Subgenital plate ( Fig. 14 ) much like that of T. horna sp. nov., with 5 basal macrosetae on outer margin. Style ( Fig. 15 ) long. Aedeagal shaft ( Figs. 16, 17 ) tubular, long and slim, slightly curved ventrally, with two asymmetrical processes at apex, and large appendage arising from base of aedeagal shaft, bifurcate near middle ( Fig. 17 ). Apical part of upper atrial appendage ( Fig. 16 ) hook-like in lateral view, and beak-like ( Fig. 17 ) in dorsal view. Gonopore ( Figs. 16, 17 ) apical. Aedeagus preatrium ( Fig. 16 ) inconspicuous; basal penis process ( Fig. 16 ) distinctly shorter than aedeagal shaft.

Specimen examined. Holotype, male, China, Hainan Prov., Jianfeng Town, 800 m, light trap, 12 July 2007, coll. Yuehua Song.

Measurement. Body length male 3.5 mm.

Remarks. This new species resembles T. communis Dworakowska (1994) , sharing with the latter the apically hook-like appendage of the aedeagus ( Fig. 16 ); and a similarly shaped style and connective ( Figs. 15, 17 ). In external appearance ( Fig. 11 ), the two species are also very similar; but they may be distinguished by the following characters:

(1) the new species has the aedeagal shaft ( Figs. 16, 17 ) with two lamina-like asymmetrical processes at the apex; T. communis has the aedeagal shaft with pair of thorn-like slim short processes preapically; (2) the new species has the gonopore ( Figs. 16, 17 ) apical; that of T. communis is subapical; (3) the basal penis process of T. communis is long and strong; the basal penis process ( Fig. 16 ) of the new species is short.

Etymology. The species is named for the type locality, Jianfeng Town, Hainan.
