Domahovski, Alexandre Cruz, Gonçalves, Clayton Corrêa, Takiya, Daniela Maeda & Cavichioli, Rodney Ramiro, 2014, Seven new South American species of Regalana DeLong & Freytag (Cicadellidae: Iassinae: Gyponini), Zootaxa 3857 (2), pp. 225-243 : 235

Regalana prestoi sp. nov.

( Figs 52 ─63, 102)

Diagnosis. Male pygofer (Fig. 57) with posterior margin broadly rounded. Style (Figs 59, 60) with ventral margin serrated on apical half. Aedeagus (Figs 61─63) shaft without lateral spiniform processes; apex with single pair of processes: LV directed ventrally, extended anterior to shaft in lateral view, and without projections.

Measurements (mm). Holotype male: total length 8.72

Coloration. Male sternite VIII (Fig. 56) basal third with paired maculae next to lateral margins and over median line, posterior margin with median macula extending towards the center, brown.

External morphology. Head ( Fig. 52 ) with transocular width about 4/5 of pronotum humeral width. Clypeus (Fig. 53) width about 3/4 of length; apical margin slightly emarginated. Forewing (Fig. 55) approximately 3.5 times longer than wide.

Male terminalia. Sternite VIII (Fig. 56) with lateral margins straight, posterior margin concave medially. Pygofer (Fig. 57) with posterior margin broadly rounded. Valve, in ventral view, with lateral margins convergent posteriorly; posterior margin convex. Subgenital plate (Figs 57, 58) widest in basal half. Connective (Fig. 59) short with rami narrow, longer than shaft; apex truncate. Style (Figs 59, 60) highest at middle portion of blade, apical portion with ventral margin serrated at apical half. Aedeagus (Figs 61─63) shaft tubular, elongated, and curved dorsally; apex flattened and dorsally expanded with short spiniform marginal processes and pair of spiniform processes on posterior surface, with one pair of processes: anteromedian (AM) absent, anterolateral (AL) absent, laterodorsal (LD) absent, lateroventral (LV) spiniform long and slender, approximately half length of shaft, directed ventrally, arising anterior to shaft and directed anteroventrally in lateral view, and without projections.

Female unknown.

Etymology. The new species name alludes to Presto, the magician, one of the protagonists of the TV series Dungeons & Dragons.

Material examined. Holotype male, “ Peru, Cuzco, Ttio\ 30.viii.2012, (Light)\ 13°31’54”S 70°53’55”W \ 2000m R.R. Cavichioli leg.”, MUSM.

Notes. Regalana prestoi sp. nov. is the largest species of the genus. It can be easily distinguished from other Regalana species by the diagnostic characters above, in addition to a less dorsally produced scutellum tubercle and aedeagus (Figs 61, 62) with a single pair of apical processes.

The new species was collected with a light trap in montane Andean forest.
