Cao, Yanghui, Huang, Min & Zhang, Yalin, 2011, First records of the genera Chagria and Davmata from China (Hemiptera: Cicadellidae: Typhlocybinae: Erythroneurini), with descriptions of two new species, Zootaxa 3023, pp. 61-67 : 65-66

Davmata falcata sp. nov.

( Figs. 4–6 , 31–41 )

Description. Ground color pale to yellow-whitish. Eyes brown, vertex with short streak at apex and two patches mesad of the eyes ochre-yellow ( Fig. 4 ). Face pale ( Fig. 6 ). Pronotum with large orange patch medially, and pair of smaller light ochre-yellow sublateral patches. Basal triangles and patch on scutellum yellowish-brown, tip of scutellum black ( Fig. 4 ). Fore wing pale, with dark brown spots and ochre-yellow patches ( Fig. 4 ).

Abdominal apodemes almost reaching hind margin of 5th sternite ( Fig. 33 ).

Pygofer side with about 4 rigid macrosetae at lower basal angle, and some gracile microsetae; caudal part with small spiny sculpture; pygofer dorsal appendage falcate ( Fig. 34 ). Subgenital plate with 4–5 macrosetae in a row ( Fig. 36 ). Style with apical part finger-like, preapical lobe large, with some sensory papillae ( Fig. 37 ). Connective V-shaped ( Fig. 38 ). Aedeagal shaft with twisted hook-like process apically; with long rod-like process basally; dorsoatrium undeveloped, short and broad; gonopore subapical and ventral ( Figs. 39–41 ). Specimen collected at Guanping with aedeagus a mirror image of those collected at Yexianggu ( Fig. 41 ).

Measurement. Male length 2.0–2.1mm (including wing).

Material examined. Holotype: 3, CHINA, Yunnan Prov., Jinghong, Yexianggu, at light, 30 August 2010, coll. Zhang Meng; Paratypes: 3, same data as holotype; 3, CHINA, Yunnan Prov., Jinghong, Guanping, at light, 29 August 2010, coll. Zhang Meng.

Diagnosis. The new species is superficially similar to D. neka , but can be distinguished by its male genitalia as follows: pygofer dorsal appendage falcate, not bifurcate at apex; style with apical part finger-like; aedeagus with one process apically and one basally.

Etymology. The name “ falcata ” is derived from the Latin adjective “falcatus” which refers to the falcate pygofer dorsal appendage.
