Wang, Xian-Yi, Li, Zi-Zhong & Dai, Ren-Huai, 2020, Three new species of the leafhopper genus Thagria Melichar (Hemiptera Cicadellidae: Coelidiinae) from China, Zootaxa 4821 (2), pp. 363-370 : 364-365

Thagria fimbriata sp. nov.

( Figs 1 C, G, K , 3 A–G)

Description. Measurements. Male. Body length (including tegmina): 8.6–8.9 mm. Head width (including eyes): 1.94 mm. Crown length × width: 1.09 × 0.85 mm; eyes width: 0.58 mm; clypeus length: 1.40 mm. Pronotum length × width: 0.89 × 2.30 mm. Scutellum length: 1.18 mm.

External morphology. Male. General color dark brown to black ( Fig. 1 C, G ). Head with numerous black markings. Crown brown, eyes and ocelli light brown ( Fig. 1 C, G ). Face brown, with numerous black markings ( Fig. 1 K ). Pronotum and scutellum with numerous light brown granules ( Fig. 1 C, G ). Forewing brown with venation darker-brown, with numerous irregular light spots ( Fig. 1 C, G ).

Moderately long, slender species ( Fig. 1 C ). Head with anterior margin arched ( Fig. 1 C, G ). Crown wide and broader than eye width, extending beyond eyes about 1/4 median length ( Fig. 1 C, G ). Face with clypellus short, base weakly inflated ( Fig. 1 K ).

Male genitalia. Pygofer in lateral view with round, elongate caudoventral lobe, caudodorsal margin with pair of long processes ( Fig. 3 A ). Segment X process wide and flat. Dorsal connective broadly U-shaped in ventral view ( Fig. 3 B ). Style wide, exceeding apex of aedeagal paraphysis, gradually expanded distally, middle region with numerous fine setae, with four digitate processes on apex ( Fig. 3 C ). Aedeagal shaft nearly reaching middle of ventral paraphysis; gonopore apical; ventral paraphysis asymmetrical, slender, slightly curved, base broad, and strongly curved at apex in lateral view, subbasally with pair of processes on dorsal margin ( Fig. 3 D–E). Connective Yshaped, stem short and narrow ( Fig. 3 F ). Subgenital plate relatively broad, with row of macrosetae from mid-length to subapex, distal margin with slender setae ( Fig. 3 G ).

Female. U nknown.

Host. Unknown.

Material Examined. Holotype: male, China: Bao Shan County, Yunnan Province, 03. VIII. 2018, collect-ed by Wang Xianyi . Paratype: male, same data as holotype except 05. VIII. 2018, collected by Yang Lu. No. CTW19002.1–2 .

Distribution. China (Yunnan province).

Etymology. The new species name is the Latin word “ fimbriata ” referring to the style with finger-like processes.

Remarks. This new species is similar to T. philagroides ( Jacobi, 1914) (Fig. 170, Li & Fan, 2017), but can be distinguished by the aedeagal paraphysis with pair of subbasal processes.
