Cao, Yanghui, Yang, Meixia & Zhang, Yalin, 2016, Review of the leafhopper genus Alnetoidia Dlabola (Hemiptera: Cicadellidae: Typhlocybinae: Erythroneurini) from China, with descriptions of two new species, Zootaxa 4193 (3), pp. 573-587 : 579-580

Alnetoidia (Alnella) dentata sp. nov.

( Fig. 6 )

Description. Body yellowish, without markings.

Apodemes ( Fig. 6 a) extended to 4th sternite.

Pygofer side ( Fig. 6 b) with 3 stout macrosetae at inner side of posterior margin; dorsal appendage long, curved ventrad, apex blunt. Subgenital plate ( Fig. 6 e) bearing group of long setae near base and row of stout microsetae from near base to near apex, with 3 macrosetae at middle part along outer margin. Style ( Fig. 6 f) with basal part thin, apex footlike with some furrows. Connective ( Fig. 6 g) broad, lateral arms slim and long. Aedeagal shaft ( Figs 6 h, i) depressed, with pair of slim processes at middle part of lateral margins, exceeding gonopore, with small fingerlike process just beneath gonopore, apex weakly sclerotized and serrate; dorsal apodeme rudimentary, preatrium shorter than aedeagus shaft; gonopore apical on ventral side.

Measurement. Male 2.89mm.

Material examined. Holotype: ♂, CHINA, Yunnan Prov., Xinzhu , 2400–2500m, 16 xi 1999, coll. I. Dworakowska .

Remarks. The new species is similar to A. (Alnella) triseta Dworakowska , but can be distinguished by broader aedeagal shaft and its serrate apical margin, and presence of a small fingerlike process beneath the gonopore.

Etymology. The specific epithet is derived from the Latin word “ dentatus ”, referring to the serrate apex of the aedeagal shaft.
