( Figs 2 A–I) Description . Length of male 3.4–3.6 mm . Female 3.7–3.8 mm . Head with black spots on anterior margin of crown relatively large, pair of smaller black spots present adjacent to anteromedial margins of eyes; crown between eyes nearly uniformly orange; pronotum mostly orange with median longitudinal white stripe incomplete, posterior margin narrowly bordered with white; scutellum orange, midline dark brown ( Fig. 2 A). Male: Second sternal apodemes (2S) ( Fig. 2 B) short, not reaching posterior margin of third segment. Pygofer ( Figs 2 C–E) with posterior margin slightly produced, disc with four or five macrosetae and some microsetae near basal ventral margin; dorsal process with bifurcated apex; ventral process curved ventromesad, not exceeding apical margin of pygofer. Subgenital plate ( Fig. 2 F) with 4 or 5 macrosetae. Style ( Fig. 2 G) short with rounded preapical lobe. Aedeagus ( Figs. 2 H–I) atrium with paired dorsal processes with convergent apices, long unpaired ventral process with bifurcate apex and irregular denticulate lobe between ventral process and shaft; shaft short and straight, gonopore apical. Material examined . Holotype male, ARGENTINA : Jujuy, P.N. Calilegua 600m 23°45´40”S 64°51´10”W , 15.i. 2008 , Dietrich et al col. Hand collected [ MLP ]. Paratypes : 2 males , same data as holotype except hand collected and Hg vapor lights [ INHS ]. Etymology . The specific name refers to the forceps shape of the dorsal processes of the aedeagus, in dorsal view. Notes . This species closely resembles R . superba but has the aedeagus with ventral process longer than shaft and dorsal processes.
