Gonçalves, Clayton Corrêa, Prando, Jádila Santos & Domahovski, Alexandre Cruz, 2025, Review of the genus Tenuacia DeLong (Insecta: Hemiptera: Cicadellidae: Gyponini), including two new species and Rubacea DeLong raised to generic status, Zootaxa 5604 (3), pp. 361-372 : 366

Rubacea indivisa sp. nov.

( Figs 1–12)

Diagnosis. Face ( Fig. 3) almost completely black. Male sternite VIII ( Fig. 5) with lateroventral margins expanded, forming a lateral lobe on middle third. Male pygofer ( Fig. 6) with dorsal margin slightly excavated. Subgenital plate ( Fig. 8) obovate, expanded apically. Aedeagus ( Figs 11, 12) shaft with subapical processes unbranched, elongated and slender, directed dorsally with apices acute.

Total length. Males, 9.0–9.1 mm (n = 2).

Description. Frons ( Fig. 3) with irregular striae. Other external morphological characters as in generic description.

Coloration. Face ( Fig. 3) black, anterior margin of crown, antennal pits, and antennal ledges, yellow; gena with subtriangular macula, below eye, adjacent to margin, yellow. Pronotum ( Fig. 1) with brown punctures. Other coloration characters as in generic description.

Male terminalia. Sternite VIII, in ventral view ( Fig. 5), approximately 1.1x wider than long; lateroventral margins expanded, forming a lateral lobe on middle third; posterior margin slightly emarginated. Valve, in ventral view, with posterior margin rounded. Pygofer, in lateral view ( Fig. 6), approximately 2.6x longer than high; basidorsal process elongated and slender, directed ventrally; dorsal margin slightly excavated; basiventral margin broadly rounded; apex strongly tapered, but rounded; in dorsal view ( Fig. 7) with lateral lobes slightly internally curved preapically. Subgenital plates, in lateral view ( Fig. 6), extending to apical half of pygofer; obovate in ventral view ( Fig. 8), expanded apically; approximately 3.5x longer than maximum width; lateral margins slightly rounded; dorsal and outer lateral surface with hair-like setae throughout apical two-thirds; apex rounded. Connective, in dorsal view ( Fig. 9), about one-third as long as style. Style in lateral view ( Fig. 10), with blade slightly sinuous at apical portion; apex rounded. Aedeagus ( Figs 11, 12) shaft with subapical processes asymmetrical, elongated and slender, directed dorsally, left process one-third longer than the right process, apices acute.

Female. Unknown.

Etymology. The name of the species alludes to the processes of the aedeagus, which are undivided ( Figs 11, 12), unlike the processes of Rubacea rubera , which are bifid.

Material examined. Male holotype: “ Peru, Pasco Department,\ P.N. Yanachaga Chemillén,\ Puesto de Control Huampal,\ 1050m., 05.x.2002 \ 10°11’08”S, 075°34’25”W,\ D.M. Takiya ” “DNA voucher:\ Entomologia DZRJ\ ENT2422” ( MUSM); Paratype: 1♂, “ Peru, Cuzco, Estrada 30C, \ 26Km W Quincemil \ 23.viii.2012 (light) \ 13º21’18”S 70º53’22”W \ 985m R.R. Cavichioli ” ( DZUP) .

Notes. Rubacea indivisa sp. nov. is very similar to R. rubacea . However, the new species differs mainly in having non-bifurcated subapical processes of the aedeagus ( Figs 11, 12), while in R. rubacea the subapical process of the left side is bifid apically ( Figs 16–21).
