Tiodus sakakibarai Paladini & Cavichioli

sp. nov.

Tiodus sakakibarai Paladini & Cavichioli  sp. nov.

( Figures 1–8View FIGURE 1 – 8)

Measurements (mm). Total length, 11.6 mm; length of pronotum, 2.3 mm; width of pronotum, 4.0 mm; length of tegmina, 8.3 mm; width of tegmina, 2.2 mm.

Diagnosis. Postclypeus orange, moderately inflated, slightly angulated in profile; tegmina black with two reddish orange transverse transcommissural bands; aedeagus robust, not bifid.

Description. Head: black ( Figs 1–2View FIGURE 1 – 8); compound eyes brown, rounded and arranged transversely; vertex smooth and rectangular, lacking median carina; ocelli brown, closer to each other than to compound eyes; tylus smooth and rectangular, lacking median carina; antennae black with scape orange, pedicel setose, basal body of flagellum subcylindrical with one arista as long as flagellum; postclypeus orange, inflated, slightly angulated (forming an obtuse angle) in profile, with one longitudinal carina strongly marked and produced; rostrum extending to mesocoxae. Thorax: reddish orange with basisternum black; pronotum black with anterolateral margins reddish orange, hexagonal, lacking median carina, anterior margin straight, anterolateral margins straight, posterolateral margins slightly sinuous, posterior margin grooved; scutellum black with a light central concavity, lacking horizontal grooves; tegmina black, each with two reddish orange transverse transcommissural bands, one between basal and median third and another on apical third, apical reticulation well developed; hindwings hyaline with orange brown venation, vein Cu1 not thickened at base; legs orange with tibiae and tarsi black; metathoracic tibiae each with two lateral spines (basal spine equal in size to spines of apical crown; apical spine larger than spines of apical crown); apical crown of spines on tibia consisting of two rows; basitarsi each with one row of spines covered by long setae; subungueal process absent. Abdomen: pale to brownish-orange.

Male genitalia. Genital chamber with finger-like process on posterior margin of pygofer ( Fig. 3View FIGURE 1 – 8); subgenital plates long and wide with rounded apex, free for almost entire length ( Fig. 4View FIGURE 1 – 8); parameres long and slender, with finger-like apex and rounded process at apical third, without spine or spine-like processes, dorsal margin rounded ( Figs 5–6View FIGURE 1 – 8); aedeagus robust with shaft straight, slightly enlarged at median third, shaft with processes: single dorsal process located on the beginning of apical third; bifid process on apex of shaft, finger-like in lateral view and Cshaped in dorsal view; and two flap-like lateral processes located on median third. ( Figs 7–8View FIGURE 1 – 8).

Female. Unknown.

Remarks. The color pattern of this species is unique in the genus. The male genitalia differ from the other species by the absence of a paramere spine and the entire (not bifid) aedeagus shaft. The postclypeus shape and angle; the general shape of the aedeagus, principally the single process on the apical third and the two processes on the apex; and the elongated parameres with a thinner apex are characters that justify placement of this species in the genus Tiodus  .

Etymology. The species is named in honor of Dr. Albino Morimasa Sakakibara for his great contributions to the knowledge of the Auchenorrhyncha.
