Zhou, Xian, Zhang, Yalin & Huang, Min, 2022, New leafhopper species and new records of Typhlocybini (Hemiptera, Cicadellidae, Typhlocybinae) from China, ZooKeys 1082, pp. 135-151 : 135

Shamala annulata sp. nov.

Figs 24 , 28 , 32 , 36 , 63-71

Note.

Body cream (Fig. 24 ). Scutellum orange with basal triangles yellowish green (Fig. 28 ). Forewing bluish white with brownish patch on CuA’’.

Abdominal apodemes extending to distal margin of 4th sternite.

Male genitalia. Pygofer side with several macrosetae ventrally and rigid short setae terminally (Figs 63 , 64 ). Subgenital plate long and narrow with row of short peg-like setae from middle part to apex on outer margin (Fig. 66 ). Connective slender with short central lobe, stem relatively long (Fig. 68 ). Aedeagal shaft with four asymmetrical processes apically, of which two dorsal processes are longer and curved inward forming a ring-like shape, two ventral processes straight and slightly divergent (Figs 69-71 ).

Specimens examined.

Holotype: ♂, China, Yunnan Province, Sanchahe , 7.vi.1991, coll. Rungang Tian. Paratypes: 3♂♂, same data as holotype .

Measurement.

Male, 2.94 mm (including wing).

Etymology.

The name of this species is derived from the Latin word “annulus”, referring to the two dorsal processes of the aedeagal shaft forming a ring-like shape.

Remarks.

This new species resembles Shamala ricasta Dworakowska, 1981 in the structure of the male genitalia, but it differs from the latter by the two longer apical processes of aedeagal shaft forming a ring-like shape.
