Introduction

The leafhopper genus Bambusana (Deltocephalinae, Athysanini) was established by Anufriev (1969) with two species: B. bambusae (Matsumura, 1914) (type species) and B. jenjouristi Anufriev, 1969 from Japan. Later, Anufriev and Emeljanov (1988) reported B. bambusae from the Soviet Far East. Dai and Zhang (2006) first recorded this genus from China and described two new species: B. fopingensis and B. multidentata, and reported B. bambusae from China. Recently, Li (in Li et al. 2011) described two new species from China: B. biflaka and B. nigrimaculata, and recognized B. fopingensis as a junior synonym of B. multidentata in their study but did not provide any justification for the synonymy. We here still recognize B. fopingensis as a valid species based on the pygofer with a strong ventro-caudal process which is significantly different from B. multidentata.

In this paper, a new species, B. longispina sp. nov. is described and illustrated from Yunnan Province, China bringing the total in the genus to seven (six from China); see key.

Material and methods

The terminology of morphological and genital characters follows Li et al. (2011) and Zahniser and Dietrich (2013). Male specimens were used for the descriptions and illustrations. External morphology was observed under a stereoscopic microscope and characters were measured with an ocular micrometer. Color pictures for adult habitus were obtained by using the KEYENCE VHX-1000 system. The genital segments of the examined specimens were macerated in 10% NaOH and drawn from preparations in glycerin jelly using a Leica MZ 12.5 stereomicroscope. Illustrations were scanned with a Canon CanoScan LiDE 200 and imported into Adobe Photoshop CS8 for labeling and plate composition.

The type specimens of the new species are deposited in the Institute of Entomology, Guizhou University, Guiyang, China (IEGU).

Diagnosis

This genus can be differentiated from other genera of Athysanini by the follow characters: relatively elongate leafhoppers with crown slightly longer medially than next to eyes; male pygofer side elongate, with one or two well sclerotized processes on ventral margin; subgenital plate usually elongate, triangular; aedeagus with basal apodeme usually present, shaft with or without small distal processes; gonopore apical or apical on ventral surface.

Description

Body elongate. Head including eyes subequal to or slightly wider than pronotum (Figs 1, 21, 24, 27, 30, 33). Crown with anterior margin roundly produced anteriorly, distinctly shorter medially than width between eyes (Figs 1, 21, 24, 27, 30, 33). Transition of crown to face rounded (Figs 5, 22, 25, 28, 31, 34); ocellus situated on or near frontal lateral margin of crown, less than 1/3 distant from eye to crown apex (Figs 1, 21, 24, 27, 30, 33). Clypellus widening apically, relatively flat (Figs 6, 23, 26, 29, 32, 35). Pronotum with anterior margin strongly and roundly produced, posterior margin slightly concave. Scutellum subequal to or slightly shorter than pronotum (Figs 1, 4, 22, 25, 28, 31, 34). Forewing elongate and rounded apically, considerably longer than abdomen, with four apical cells; appendix well developed (Figs 1–3, 21, 22, 24, 25, 27, 28, 30, 31, 33, 34).

Type material

Holotype : ♂, China: Yunnan Province, Maguan County, 23. XI. 2016, Ya-Lin Yao. Paratype: 1♀, same as holotype.

Host plants

. Bamboo.

Distribution

Southwest China (Yunnan Province).

Remarks

This new species is similar to B. bambusae, but can be distinguished from the latter by: aedeagus with a long medial process subbasally from ventral margin, directed dorsally (Figs 10, 11) (aedeagus with a tooth-like ventro-basal process, directed ventrally in bambusae); shaft long and tapered to apex, with two pairs of small triangle processes near apex (Figs 9–11) (shaft without process subapically in bambusae).

Etymology

The name is derived from the Latin words “longus” and “spina”, referring to the aedeagus with a long spinous process near base (Fig. 11).
