Cao, Yanghui, Dmitriev, Dmitry A. & Zhang, Yalin, 2018, New species of the leafhopper genera Kusala Dworakowska and Diomma Motschulsky (Hemiptera: Cicadellidae: Typhlocybinae: Erythroneurini) with description of a new subgenus, Zootaxa 4514 (2), pp. 263-272 : 265

Kusala (Kusala) viraktamathi sp. nov.

( Figs 1 , 5 a–d)

Description. Ground color greyish brown, face light brown. Anteclypeus broad. ( Figs 5 a–d)

Male 2S abdominal apodemes ( Fig. 1c ) extended to hind margin of sternite IV. Anal tube appendage ( Figs 1d, e ) long.

Subgenital plate ( Figs 1d, g ) with about 4 thick and 3 thin macrosetae. Apical part of style ( Fig. 1h ) broad, with dense furrows. Connective ( Fig. 1i ) with lateral arms slightly sinuated. Aedeagus ( Figs 1 j–l) very similar to that of K. (K.) salicis ( Ahmed, 1970), dorsal lamella long, with serrated margin, shaft with finger-like ventral process subapically; dorsal apodeme relatively long in lateral view; preatrium slim, length subequal to shaft.

Diagnosis. The new species is similar to K. (K.) salicis, but the style is broad apically with a larger preapical lobe, the connective has the lateral arms slightly sinuate, and the ventral process of the aedeagal shaft is subapical.

Measurement. Male length 2.50–2.70mm, female length 2.50–2.80mm.

Material examined. Holotype: ♂, CHINA, Yunnan Prov., Jinghong , 600m, Urtica sp., 25 xii 1999, coll. I. Dworakowska; paratypes: 16♂♂ 22♀♀, same data as holotype.

Etymology. The new species is named in honor of Dr. Chandra A. Viraktamath (University of Agricultural Sciences, Bangalore, India).
