Cao, Yanghui & Zhang, Yalin, 2014, Taxonomic study of the leafhopper genera Gredzinskiya Dworakowska and Musbrnoia Dworakowska (Hemiptera: Cicadellidae: Typhlocybinae: Erythroneurini) with descriptions of seven new species, Zootaxa 3753 (1), pp. 59-70 : 68-69

4. Musbrnoia corollaris sp. nov.

( Figs 2 e–h, 8)

Description. Body shape and coloration ( Figs 2 e–h) apparently indistinguishable from that of M. angusta sp. nov..

Pygofer side ( Fig. 8 b) long, narrowing caudad, with two groups of rigid setae at dorso-caudal angle and near ventro-caudal margin respectively; dorsal appendage ( Fig. 8 c) similar to that of M. angusta sp. nov., but apex expanded and pointed ventrally. Subgenital plate ( Fig. 8 e) with 3–4 macrosetae and about 4 peglike microsetae beneath subapical angulate projection. Style ( Figs 8 g, h) relatively broad, preapical lobe unconspicuous in dorsal view. Connective ( Fig. 8 i) Y-shaped, lateral arms tapering apically. Aedeagal shaft ( Figs 8 j, k) depressed, broadened centrally and narrowing towards apex, lateral margins serrated basally and bent dorsad, with crownlike process apically; gonopore subapical.

Measurement. Male length 4.6mm.

Material examined. Holotype: ♂, THAILAND, Petchaburi, Kaeng Krachan, NP Panernthung/km30, 12°49.598'N, 99°21.827'E, Malaise trap, 19-26. ix. 2008, coll. Sirichai & Jatupon.

Deposition. QSBG, Chiang Mai, Thailand.

Diagnosis. Differing from other species in the broadened apex of the pygofer dorsal appendage and the distinctive shape of the depressed aedeagus.

Etymology. This new specific epithet is derived from Latin word “ corollaris ”, meaning crown, referring to the shape of aedeagus apex.
