Domahovski, Alexandre Cruz, Gonçalves, Clayton Corrêa, Takiya, Daniela Maeda & Cavichioli, Rodney Ramiro, 2020, Description of two new species of Regalana and a new genus of Gyponini (Hemiptera: Cicadellidade: Iassinae), Zootaxa 4731 (1), pp. 89-102 : 95-97

Delongiana baiana sp. nov.

( Figs 27 −39, 67)

Diagnosis. Male sternite VIII (Fig. 31) wider than long. Pygofer (Fig. 33) with apicoventral margin obliquely straight. Aedeagus (Figs 37−39) shaft with pair of elongated and sinuous lateral processes arising from mid-length, produced dorsally as far as shaft apex.

Measurements (mm). Holotype male: total length 7.6.

Coloration. Frons (Fig. 28) black along frontogenal sutures. Other characteristics as in generic description.

Description. External morphological characters as in generic description.

Male terminalia. Sternite VIII (Fig. 31) in ventral view, subrectangular, approximately 1.5 times wider than long; lateral margins straight and parallel; posterior margin slightly concave. Valve (Fig. 32) in ventral view, approximately 1.5 times wider than long; lateral margins convergent toward apex; ventral margin roundly produced at middle portion. Pygofer (Fig. 33) in lateral view, with apicoventral margin obliquely straight. Subgenital plate (Fig. 33) in lateral view, produced posteriorly as far as pygofer apex; in ventral view (Fig. 34), approximately 5.1 times longer than wide. Connective (Fig. 35) in dorsal view, with arms longer than stem; stem narrow. Style (Fig. 35) in dorsal view, with outer lobe broadly acute; in lateral view (Fig. 36), with blade expanded near apex. Aedeagus (Figs 37−39) shaft with pair of elongated and sinuous lateral processes arising at mid-length and extended dorsally as far as shaft apex, apices of processes acute. Other characteristics as in generic description.

Female unknown.

Etymology. The specific epithet baiana (Latinized adjective) means in Portuguese “inhabitant of or related to the Brazilian State of Bahia ”.

Material examined. Holotype male, “ Brasil, Bahia,\ Encruzilhada \ X.1975 \ M. Alvarenga leg.”, DZUP . Paratypes: 1♂, “ Brasil, RJ, Rio de Janeiro,\ Taquara, Rua Cidade do Rio ,\ número 138, 22°55’44”S \ 43°23’07”, 80m \ 07.xii.2014, Luz \ A.D.L.Ferreira ”, DZRJ ; 1♂, same as preceding except “ vii.2014 ”, DZRJ ; 1♂, “ Brasil, RJ, Cachoeira do Macau \ Reserva Ecológica de Guapiaçu \ 28-29.vi.2013 pano branco\ Gonçalves C.C.”, DZRJ .

Notes. Delongiana baiana sp. nov. is easily differentiated from D. ramosa sp. nov. mainly by its unbranched aedeagus processes.
