He, Hongli, Yang, Maofa & Yu, Xiaofei, 2018, Three new species of the leafhopper genus Processina (Hemiptera: Cicadellidae: Mileewinae) from Thailand, Zootaxa 4531 (2), pp. 279-287 : 281-283

Processina topoarmata sp. nov.

( Figs. 5–8, 13–14 , 34–44 )

Description. Crown yellowish white, with large black spot medially and black anterior margin ( Figs. 5, 7 ). Eyes and ocelli pale. Pronotum tawny, infused anteriorly and posteriorly with dark. Scutellum yellowish white, basal triangles dark brown ( Figs. 5, 7 ). Forewing dark brown, translucent, basal half of costal margin black, veins dull yellow ( Figs. 5, 6, 7, 8 ). Face pale with dark brown wide median longitudinal band across frontoclypeus, complete in male and interrupted medially in female ( Figs.13, 14 ). Venter of thorax pale, legs pale with fore tibiae and tarsi, mid tarsi, and apices of hind tarsi dark brown.

Male genitalia. Male pygofer ( Fig. 34 ) well produced posteriorly, in lateral view with posterior margin angularly convex, ventral margin with small setae; pygofer process slender and short, extending posteriorly only to middle part of lobe, unbranched. Subgenital plates ( Fig. 37 ) extending to pygofer apex, surface with uniseriate macrosetae medially, with many microsetae mostly on outer lateral portion. Aedeagus ( Figs. 35, 36 ) with shaft bent dorsad subbasally, with pair of apical long process extended laterad and sinuate, and thorn-shaped median ventral process at midlength; basal apodeme well developed, broad in lateral view. Connective ( Fig. 38 ) Y-shaped. Style ( Fig. 39 ) slender and short, apex narrowly rounded with dense fine setae.

Female Genitalia. Female seventh sternite ( Fig. 40 ) with posterior margin parabolically rounded; first valvulae ( Figs. 41, 42 ) relatively slender, slightly tapered through most of length then strongly and evenly tapered to acute apex, dorsal and ventral preapical sculpturing densely scaly; second valvulae ( Figs. 43, 44 ) similar to that of P. chandrai but with dorsal teeth very poorly developed.

Measurement. Male: 5.1 mm, female: 5.6 mm.

Material examined. Holotype: ♂, THAILAND, Chiang Mai Doi Phahompok NP Kewl om 1/m ontane forest, 20°3.549'N 99°8.552'E, 2174 m, Malaise trap, 31.vii–7.viii.2007, Wongchai. P. leg. T2953 . Paratype: 1♀, THAILAND, Mae Hong Son Namlok Mae Surin NP Beside Small stream, 19°20.803 'N 97 °59.014'E, 293 m, Malaise trap, 28.x–4.xi.2007, Areerat Kumkhun leg. T2817 .

Etymology. The specific name combines "topo-" (place) with "arma" (weapon) and refers to the thorn-shaped preapical process of the aedeagus.

Remarks. The new species is similar to P. dashahensis in appearance, but differs from the later in having a dark brown longitudinal wide band on the frontoclypeus, the veins of the forewing off-yellow, the aedeagus with only an unpaired thorn-shaped process at midlength and the pygofer process unbranched.

Distribution. Thailand.
