Sun, Jing, Zhang, Yalin, Lu, Lin & Webb, M. D., 2019, A new species and new record of the leafhopper genus Balclutha (Hemiptera: Cicadellidae: Deltocephalinae) from China with key to species, Zootaxa 4551 (4), pp. 494-500 : 497

Balclutha longispina sp. nov.

( Fig. 1 )

Description. Length (including tegmen). Male: 3.5–3.8mm.

Body yellowish. Vertex marked with stramineous. Pronotum near posterior margin with orange tinge. Scutellum yellow. Ocelli green; forewings greenish, hyaline, smoky brown at apex.

Head narrower than pronotum. Vertex roundedly produced, midlength slightly longer than next to eyes; ocelli 2.0 times own diameter from corresponding eyes. Hind femur setal formula: 2+2+1.

Male genitalia. Pygofer distinctly produced posteriorly and tapered to acute projection. Valve broad, triangular. Subgenital plates very long, extended slightly beyond projection of pygofer, with row of lateral macrosetae. Style with apophysis long, digitate; preapical lobe well developed. Stem of connective equal to arms in length. Aedeagus with dorsal apodeme bilobed distally; socle with pair of basal parallel processes curved caudally; shaft filamentous, curved dorsally, gonopore apical.

Material examined. Holotype: male, China, Yunnan Prov., Mengla County, Longmen Country , 14.v.2013, Coll. Xue Qingquan ; Paratype: male, same data as holotype; males, same data as holotype except 15.v.2013 ( NWAFU) .

Distribution: China (Yunnan).

Remarks. This species resembles B. sternalis and B. versicolor in color and external characters, but can be distinguished from them and other species by the dorsal apodeme and socle of the aedeagus having paired processes, the very long subgenital plate, and the attenuate, spinelike pygofer apex.

Etymology. The species name “longispina” refers to the long pygofer caudal spine.
