Catalano, María Inés, Paradell, Susana L. & Dietrich, Christopher H., 2013, Four new species of genus Parallaxis McAtee (Hemiptera: Cicadellidae: Typhlocybinae: Dikraneurini) from Argentina, with a key to known species, Zootaxa 3737 (3), pp. 241-250 : 243-244

Parallaxis jujuiensis sp. n.

( Figs 1 A, 2A–G)

Description. Length of male: 2.7–2.8 mm.

Ground color brown, mottled with red and yellow. Crown yellow with two V-shaped dark brown spots on apical margin and two triangular spots on hind margin, coronal suture dark basally. Pronotum red medially, anterior margin mottled with brown, lateral and posterior margins yellow. Scutellum yellow with irregular light brown spots. Forewing yellowish with four rectangular red spots, two in claval area and two in brachial cell; two transverse brown stripes arising from costal margin; apical cells smoky with transparent spots, veins yellow ( Fig. 1 A). Fore and hind wing venation characteristic of genus.

Male: Second sternal apodemes (2S) ( Fig. 2 A) short, scarcely exceeding third segment. Pygofer ( Fig. 2 B) quadrangular in lateral view, with vertical row of five macrosetae posterodorsally, group of very thin and long setae near ventral margin and several microsetae on caudal margin, and pair of short convergent spines near mid-height of caudal margin. Subgenital plate ( Fig. 2 C) with nearly parallel margin, oblique single row of three or four macrosetae over basal half of disk, long and thin setae on dorsal margin and several microsetae in apical half. Style ( Fig. 2 D) with rounded preapical lobe with group of four or five small setae; apical extension falcate. Connective ( Fig. 2 E) U-shaped. Aedeagus ( Figs 2 F–G) with very small preatrium; dorsal apodeme well developed, wider at apex than at base; shaft compressed, with few small teeth on ventral surface, paired long apical processes extended ventro-cephalad and paired triangular ventral subapical processes, apex acuminate slightly extended dorsally; gonopore apical.

Female: Unknown

Material examined: Holotype male: ARGENTINA: Jujuy, P.N. Calilegua, Arroyo Tres Cruces, 1110 m., 23°41´38´´S 64°52´4´´W, 14–16 January 2008, C.H. Dietrich et al., Malaise trap [MLP]. Paratypes: 2 males, same data [INHS].

Etymology: The specific name refers to the province where the holotype was collected. Notes: This species closely resembles P. colorata Linnavuori , but has the aedeagus with basal and subapical paired processes.
