Wang, Dongming & Zhang, Yalin, 2022, Three new species in the genus Chanohirata (Hemiptera: Cicadellidae: Deltocephalinae: Penthimiini) from China, Zootaxa 5129 (3), pp. 432-441 : 435-436

Chanohirata minima Wang & Zhang sp. nov.

( Figs. 1. A–D , 3. A–F )

Measurement. Length of male including tegmen: 3.5–3.7 mm.

Coloration. Vertex pale yellowish, marked with dark brown reticulation and light brown patches, two yellowish brown spots between eyes; eyes grey with brown transverse stripe; ocelli white ( Fig. 1C ). Face black ( Fig. 1D ). Pronotum pale yellowish, marked with dark brown reticulation and yellowish brown patches. Scutellum pale yellowish with dark brown reticulation ( Fig. 1C ). Forewing subhyaline, with dense and dark brown reticulations ( Fig. 1A ).

Morphology. Head declivous, including eyes nearly as broad as pronotum; crown medial length 0.4 times width between eyes ( Figs. 1B, C ). Postclypeus flat; anteclypeus ridged medially, lateral margins slightly convex, truncate at apex ( Fig. 1D ). Pronotum length 2.0 times medial length of crown. Scutellum length 0.7 times medial length of pronotum ( Fig. 1C ).

Male genitalia. Pygophore longer than high, with short and long macrosetae near posterior margin ( Fig. 3A ). Valve triangular. Subgenital plate extending beyond apex of pygofer, nearly triangular, with sparsely distributed setae on ventral side ( Fig. 3B ). Style with developed preapical lobe, apical apophysis pointed, fingerlike, curved laterally; preapical lobe with several setae near inner margin ( Fig. 3C ). Connective ‘Y’-shaped, stem slightly longer than anterior arms ( Fig. 3D ). Aedeagal shaft slender, with two pairs of processes, lateral flange triangular, near apex, and with smaller process on apex, dorsal apodeme plate-like, well-developed, preatrium reduced, gonopore apical ( Figs. 3E, F ).

Material examined. Holotype ♂ ( NWAFU), CHINA, Yunnan Prov., Longling County, Xiaoheishan , 27 April 2012, coll. Cao Yanghui ; Paratypes: 2♂ ( NWAFU), CHINA, Yunnan Prov., Xishuangbanna , 10 June 2019, coll. Wang Dongming.

Diagnosis. This species can be distinguished from other species in this genus by the slender aedeagal shaft, with a pair of triangular preapical processes. The genus also has some resemblance to Tambila Distant , but the latter has the head in profile angled to the apex near the eye.

Etymology. This specific epithet is from the Latin word “ mini ” referring to the aedeagal shaft being slender.
