Regalana madeira sp. nov.

(Figs 14 −26, 66)

Diagnosis. Male pygofer (Fig. 20) with apex truncated dorsally and excavated on ventral half. Style (Fig. 23) expanded at middle portion of blade; ventral margin serrated at median third. Aedeagus (Figs 24−26) with dorsal apodeme very long and strongly divergent laterally; apex with three pairs of processes: anteromedian (AM) absent, anterolateral (AL) two times longer than simple laterodorsal (LD), directed anteriorly and crossed apically, and lateroventral (LV) measuring approximately half-length of shaft, directed ventrally.

Measurements (mm). Holotype male: total length 7.6. Paratypes: 7.7−7.9.

Coloration. Male sternite VIII (Fig. 18) posterior margin with brown triangular macula at middle portion. Other characteristics as in generic description in Domahovski et al. (2014).

Description. Head (Fig. 14) with transocular width about 4 / 5 of pronotum humeral width. Clypeus (Fig. 15) almost as long as wide; apical margin straight. Forewing (Fig. 17) approximately 3.2 times longer than wide. Other characteristics as in generic description in Domahovski et al. (2014).

Male terminalia. Sternite VIII (Fig. 18) in ventral view, subquadrangular, slightly wider than long; lateral margins slightly convex; posterior margin slightly produced at middle portion. Valve (Fig. 19) in ventral view, slightly wider than long; lateral margins convergent posteriorly; posterior margin produced at middle portion. Pygofer (Fig. 20) in lateral view, subquadrangular, slightly higher than long; posteroventral margin rounded; apex truncated dorsally and excavated on ventral half. Subgenital plate (Fig. 20) in lateral view, slightly exceeding apex of pygofer; in ventral view (Fig. 21), ligulate, widest at mid-length; apex tapered. Connective (Fig. 22) in dorsal view, with rami longer than stem; stem short and wide. Style (Fig. 22) in dorsal view, with outer lobe subquadrangular; in lateral view (Fig. 23), expanded at middle portion of blade; ventral margin serrated at median third; apex acute. Aedeagus (Figs 24 ─ 26) with dorsal apodeme very long and strongly divergent laterally; shaft tubular, elongated, and curved dorsally, without processes; apex with three pairs of processes: anteromedian (AM) absent, anterolateral (AL) two times longer than laterodorsal (LD), directed anteriorly and crossed apically; lateroventral (LV) measuring approximately half-length of shaft, directed ventrally and parallel to posterior margin of shaft in lateral view, with one or two accessory spiniform processes at base of each LV process. Other characteristics as in generic description.

Female unknown.

Etymology. The specific epithet alludes to the type-locality, Rio Madeira.

Material examined. Holotype male, “ Brasil, Rondônia, Porto \ Velho, Rio Madeira \ 09°26’14”S 64°49’58”W \ Malaise 04-18.IX.2012 \ MA Ullysséa & LP Prado”, MZSP. Paratypes: 1♂, same data as holotype, MZSP; 1♂, same data as holotype, DZRJ; 1♂, “ Brasil, Rondônia, Porto \ Velho, Rio Madeira \ 09°35’54”S 65°02’53”W \ Malaise 18-29.VI.2011 \ Albuquerque & Ferreira”, DZUP.

Notes. Regalana madeira sp. nov. resembles R. sheilae Domahovski, Gonçalves, Takiya & Cavichioli, 2014 by the truncated dorsal portion of the apex of the pygofer (Fig. 20) and orientation of aedeagal processes (Fig. 25). However, the medially expanded style with more acute apex (Fig. 23), aedeagus with dorsal apodeme longer and strongly divergent laterally, and the crossed anterolateral processes of the aedeagus (Fig. 25) in R. madeira sp. nov. easily distinguish it from R. sheilae and other species of the genus.
