Yang, Liyuan & Zhang, Yalin, 2014, Three new species in the leafhopper genus Pedionis Hamilton (Hemiptera: Cicadellidae: Macropsinae) from China, with a key to Chinese species, Zootaxa 3760 (4), pp. 587-595 : 594

Pedionis (Pedionis) dinghuensis sp. nov.

( Figs. 1 I–L, 4)

Description. Length. Male 3.6 mm, female 3.8 mm.

Coloration. Body pale brown with numerous dark brown spots, striations on pronotum and head strong ( Figs. 1 I, J). Ocelli white, eyes pale brown ( Fig. 1 L). Scutellum triangular, yellowish, with scattered dark notches, base of lateral sides yellow ( Fig. 1 K). Forewing hyaline-brown, except basal and distal areas which are opaque chocolatebrown, venation fuscous spotted with white ( Fig. 1 J).

Morphology. Body stout and small. Face shorter. Hind tibial spinulation R1 11, R2 8, R3 5.

Male genitalia. Pygofer ( Fig. 4 A) with an obvious incision on dorsal margin, posterior half rather straight, caudo-dorsal angle with a small spine, several setae on ventral margin. Subgenital plate of uniform width, and with many setae, several especially long at the end. Style ( Fig. 4 G) parallel-margined and angled on apical third, apex obliquely truncate. Aedeagus shaft ( Figs. 4 D, E) with 2 paired processes, subapical slender, fingerlike ones ventrally directed. Dorsal connective ( Fig. 4 F) sinuate, with broad base, apical half slender, with serrated mesal edge and provided with basal fingerlike process.

Female. Body coloration and appearance similar to male. 7th sternite with posterior margin sinuated, midline about 2.5 times longer than 6th, ovipositor strongly projecting beyond pygofer.

Distribution. China: Guangdong (Mt. Dinghu)

Material examined. Holotype. Male, China: Guangdong Province, Mt. Dinghu, 14 July 2005, coll. by Lu Lin. Paratypes: 1 male, 1 female, same data as holotype.

Remarks. Pedionis dinghuensis resembles P. rufoscutellata Huang & Viraktamath internally, but differs in having a pair of ventrally directed subapical aedeagal processes, and lacks falcate process on dorsal connective. P. rufoscutellata have processes perpendicular to shaft and have a large falcate medial process on dorsal connective.

Etymology. The new species epithet refers to the type locality, Mt. Dinghu in Guangdong Province, China.
