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 : 231-233

Regalana ericki sp. nov.

( Figs 28 ─39, 100)

Diagnosis. Male pygofer (Fig. 33) with posterior margin broadly rounded. Style (Figs 35, 36) with ventral margin serrate at apical half. Aedeagus (Figs 37─39) shaft expanded laterally as flanges with three pairs of spiniform marginal projections; apex with three pairs of processes: LV directed ventrally, extended anterad in lateral view, and with spiniform projections.

Measurements (mm). Holotype male: total length 6.72.

Coloration. Male sternite VIII (Fig. 32) with basal angles and lateral margins bordered with brown, posterior margin with brown median macula extending towards the center.

External morphology. Head ( Fig. 28 ) with transocular width about 4/5 of pronotum humeral width. Clypeus (Fig. 29) about as long as wide; apical margin straight. Forewing (Fig. 31) approximately 3.4 times longer than wide.

Male terminalia. Sternite VIII (Fig. 32) with lateral margins straight, posterior margin concave. Pygofer (Fig. 33) with posterior margin broadly rounded and folding inwardly. Valve, in ventral view, wider than the maximum length; posterior margin broadly rounded. Subgenital plate (Figs 33, 34) widest in basal third. Connective (Fig. 35) with rami longer than stem; apex rounded. Style (Figs 35, 36) apical portion with ventral margin serrate from apical two-thirds. Aedeagus (Figs 37─39) shaft elongated, and curved dorsally, tubular, but with pair of well-developed flanges directed dorsolaterally at mid-length, these bearing six pairs of small spiniform processes: four marginal and two on posterior surface near apex; apex with three pairs of processes: anteromedian (AM) spiniform and directed dorsally, anterolateral (AL) absent, laterodorsal pair (LD) long, directed anterodorsally, and originating from LV, lateroventral processes (LV) flattened, expanded, directed ventrally, and with two (right) or three (left) small spiniform projections.

Female unknown.

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

Material examined. Holotype male, “ Peru, Cuzco, Rio\ Inambari, 19.viii.2012, (Light)\ 13°10’52”S 70°22’06”W \ 364m R.R. Cavichioli leg.”, MUSM.

Notes. Regalana ericki sp. nov. is a small to medium size species of the genus. It can be easily separated from other Regalana species by the diagnostic characters above, especially the unique aedeagal shaft which is laterally expanded as flanges (Figs 37, 38).

The new species was collected with a light trap in an unflooded Amazonian Rainforest.
