Seriana menglaensis sp. n. (Hemiptera: Cicadellidae: Typhlocybinae: Erythroneurini) is described and illustrated from Southwest China. Seriana equata (Singh, 1969) is recorded for the first time from China.


Hemiptera, morphology, taxonomy


The leafhopper genus Seriana was established by Dworakowska (1971) in the tribe Erythroneurini of Typhlocybinae with Seriana frater Dworakowska, 1971 as the type species. Seriana consists of thirty-three species in the world distributed in Oriental and Palaearctic regions. The genus can be distinguished by the body fuscous, the crown usually with median dark patch on anterior margin of vertex, the pronotum with five oval grey impressed patches near anterior marign; the pygofer hind margin acutely produced, with oblique dorsolateral internal ridge and basolateral setae in distinct group and the pygofer dorsal appendage not movably articulated; the subgenital plate pocket-like apically, with 2–4 basal macrosetae and several short rigid setae on upper margin subbasally; the style apex truncate; the aedeagus usually with pair of processes and the connective nearly Y-shaped.

Only two species, Seriana indefinita Dworakowska, 1971 from Guangzhou and Seriana ochrata Dworakowska, 1971 from Taiwan were so far reported from China. We describe a new species from Yunnan Province, China and provide illustrations for both the new species and Seriana equata (Singh) recorded for the first time from China.

Methods and materials

The specimens were obtained by sweep net method and were studied under Olympus SZX7 and CX41 microscopes. Morphological techniques and terminology follow Dietrich and Dmitriev (2006). Measurements of the new species are given in millimeters; body length is measured from the apex of the head to the apex of the fore wing in repose. All specimens examined are deposited to the collection of the Insititute of Entomology, Guizhou University, Guiyang, China (GUGC).

Taxonomy Key to species of Seriana from China
1 Aedeagus with paired processes 2
Aedeagus with unpaired processes (Figs 18, 19) Seriana indefinita Dworakowska
2 The paired processes arising from the base of aedeagual shaft (Figs 6, 7) Seriana menglaensis sp. n.
The paired processes arising from the midlength of aedeagual shaft 3
3 The paired processes shorter, hook-like (Figs 16, 17) Seriana equata (Singh)
The paired processes longer, finger-like (Figs 20, 21) Seriana ochrata Dworakowska

General color fuscous. Head (Fig. 1) with vertex dirty yellow, with an irregular brown spot at anterior margin medially; eyes black. Pronotum (Fig. 1) with five whitish oval impressed patches near anterior margin. Forewing light testaceous, without markings; brochosome field blackish brown.

Head (Fig. 1) distinctly narrower than pronotum; vertex bluntly rounded.

Abdominal apodemes (Fig. 2) small, acuminate apically, not extended beyond hind margin of 3rd sternite.

Pygofer lobe (Fig. 3) broad, with distinct oblique dorsolateral internal ridge, numerous macrosetae at lower basal angle. Pygofer dorsal appendage very long and fused with dorsal margin of pygofer. Subgenital plate (Fig. 4) with three long macrosetae and short rigid setae at upper margin subbasally; several microsetae scattered on apical portion. Style (Fig. 5) long, apex truncate; preapical lobe large. Connecitve (Fig. 8) Y-shaped, stem strong, central lobe absent. Aedeagus (Figs 6, 7) with shaft long and straight, with two pairs processes, one pair very long, arising from basolateral part of shaft; another pair placed apically very short, lamellate; gonopore at apex, on ventral margin, dorsal apodeme short, weakly expanded.

Body length males 3.2 mm.

Type material.

Holotype, male, China: Yunnan Prov., Mengla County, at light, 23 July 2008, coll. Yuehua Song. Paratype: one male, same data as holotype.


The new species is similar to Seriana ochrata Dworakowska (1971), but can be distinguished from the latter by the aedeagal shaft longer and straighter, similar in width throughout length in ventral view; the paired long processes arising from the base of aedeagal shaft, not at midlength and the dorsal apodeme small.


The new species is named after its type locality: Mengla.

Seriana equata (Singh, 1969), rec. n.
