Cao, Yanghui, Yang, Meixia & Zhang, Yalin, 2013, Synonymy, new species and new combinations in the leafhopper genus Matsumurina Dworakowska (Hemiptera: Cicadellidae: Typhlocybinae: Erythroneurini), Zootaxa 3734 (4), pp. 453-468 : 467-468

16. Matsumurina serriformis Cao & Zhang sp. nov.

( Figs 2 i–l, 11)

Description. Ground color testaceous, eyes grey, basal triangles of mesonotum black. Fore wing pale, transparent, apex light brownish.

Male 2S abdominal apodemes damaged during dissection.

Pygofer side (Fig. 11a) elongated, distal half with dense denticuli, without setae; dorsal appendage (Figs 11b, c) narrowing towards subapex, almost straight, apex expended with serrated margin, slightly curved mesad, not reaching hind margin of lobe. Ligament (Fig. 11a) slim, fused with pygofer dorsal appendage. Subgenital plate (Figs 11a, e) not reaching hind margin of pygofer side, pointed apically, constriction short; about 2/3 distance from base, with 3-4 macrosetae near lateral margin and row of microsetae on distal disc, marginal microsetae reduced, from midlength to constriction. Style (Fig. 11f) almost straight, apical part short, preapical lobe small but distinct. Connective (Figs 11g, h) with lateral arms short. Aedeagal shaft (Figs 11g –i) tubular, apical processes asymmetrical, directed caudad; branch of upper atrial appendage short, lamellate; ventral process slim, longer than shaft, slightly sinuated in side view, pointed apically.

Measurement. Male length 3.40 mm.

Material examined. Holotype: ♂, THAILAND, Prachuab, Khiri Khan, Khao Sam Roi Yot NP, 200m /S of Checkpoint 1, 12°12.789'N, 99°58.662'E, Malaise trap, 19–26. x. 2008, coll. Yai; Amnad.

Deposition. QSBG, Chiang Mai, Thailand.

Diagnosis. Similar to M. angusta sp. nov., but pygofer dorsal appendage serrated apically, paired apical processes of aedeagal shaft asymmetric and preatrial process longer than shaft.

Etymology. The specific epithet is derived from Latin word “ serriformis ” which refers to the serrated form of the apex of the pygofer dorsal appendage.
