Description of two new species of Regalana and a new genus of Gyponini (Hemiptera: Cicadellidade: Iassinae) Domahovski, Alexandre Cruz Gonçalves, Clayton Corrêa Takiya, Daniela Maeda Cavichioli, Rodney Ramiro Zootaxa 2020 2020-02-04 4731 1 89 102 8JYQD Domahovski & Gonçalves & Takiya & Cavichioli, 2020 Domahovski & Gonçalves & Takiya & Cavichioli 2020 [151,373,1197,1224] Insecta Cicadellidae Regalana Animalia Hemiptera 3 92 Arthropoda species 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). Holotypemale: 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/ 5of 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.   FIGURES 14─26.  Regalana madeira  sp. nov., holotype male. 14, head and thorax, dorsal view. 15, head, frontal view. 16, head and thorax, lateral view. 17, forewing. 18–26, male terminalia: 18, sternite VIII, ventral view. 19, valve, ventral view. 20, pygofer, valve, and subgenital plate, lateral view. 21, subgenital plate, ventral view. 22, style and connective, dorsal view. 23, style, lateral view. 24, aedeagus, lateral view. 25, aedeagus posterior view. 26, aedeagus dorsal view.

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. sheilaeand other species of the genus. 2562577011 2012-09-04 2012-09-18 2012-09-04 LP, MZSP Brazil Porto -9.4372225 Rio Madeira 21 -64.83278 Velho 5 94 1 Rondonia holotype 2562577039 [843,1381,404,431] 2012-09-04 2012-09-18 2012-09-04 MZSP Brazil Porto -9.4372225 Rio Madeira 21 -64.83278 Velho 5 94 1 1 Rondonia paratype 2562577023 2012-09-04 2012-09-18 2012-09-04 DZRJ Brazil Porto -9.4372225 Rio Madeira 21 -64.83278 Velho 5 94 1 1 Rondonia paratype 2562577007 2011-06-18 2011-06-29 2011-06-18 DZUP Brazil Porto -9.598333 Rio Madeira 21 -65.04806 Velho 5 94 1 1 Rondonia paratype
