Catalano, María Inés, Paradell, Susana & Dietrich, Christopher H., 2013, Three new species of Neozygina Dietrich & Dmitriev (Hemiptera, Cicadellidae, Typhlocybinae) from Argentina, with a key to South American species, Zootaxa 3652 (1), pp. 156-162 : 159-161

Neozygina spinula sp. nov.

( Figs. 3 A–H)

Description. Length of male 2.7–2.8 mm. Ground color stramineous, infused with brown; dorsum mostly brown, anteclypeus, lateral margin of frontoclypeus and mesonotal triangles dark brown; forewing brown, veins and brocosome field yellow-orangish (fig. 3A).

Male: Second sternal apodemes (2S) (fig. 3B) slightly reaching fourth segment. Pygofer (fig. 3C) with conspicuous microsetae, one macroseta near base of dorsal appendage and other between dorsal and ventral appendage; dorsal appendage arising near base of lobe, slightly curved ventrad in lateral view and straight in dorsal view, not reaching apex of lobe; ventral appendage arising preapically, well developed, extended dorsomesad. Subgenital plate (fig. 3D) with basolateral angle acute; with submarginal row of three macrosetae; marginal row of microsetae from subbasal angle to apex. Style (fig. 3E) with preapical lobe rounded, enlarged; apex truncate with lateral angle short, acute, medial angle 90º. Connective (fig. 3F) Y-shaped with stem and arms short. Aedeagus (figs. 3G–H) with preatrium absent, dorsal apodeme T-shaped in posterior view; shaft tubular, in lateral view slender; paired subbasal ventral processes approximately half length of shaft, slightly divergent from each other, divergent from shaft in lateral view; paired distal processes arising ventrad of gonopore, long, slender, extended ventrolaterad; apex in posterior view bifid, forming pair of forcipate apical dorsal processes with short lateral spine near midlength of each process; gonopore apical.

Material examined. Holotype male, ARGENTINA: P.N. Calilegua 600m 23°45´40”S 64°51´10”W, Jujuy province, 15 January 2008 (Dietrich col. Hg. vapor lights) [MLP]. Paratype: 1 male, same data as holotype [INHS]. Etymology. The specific name refers to the lateral spines of the distal aedeagal appendages. Note. This species closely resembles N. forcipata but has a macrosetae between both pygofer processes and the dorsal pygofer appendage with a lateral spine, and lacks small teeth near the base of the dorsal margin of the aedeagus.
