Gibbocicada brasiliana View in CoL sp. nov.

( Figs 2–18 View Figs 2–11 View Figs 12–14 View Figs 15–18 )

Type locality. Brazil, Ceará state, Mucambo municipality, Carquejo village, ca. 3°52′S, 40°44′W.

Type material. HOLOTYPE:, ʻBRAZIL / Carquejo / Est Ceará / Dirings // IV 1960 ʼ ( MZSP, dry-mounted ona pin; Fig. 2 View Figs 2–11 ). GoogleMaps PARATYPES: 2 1 ♀, same data as the holotype ( MZSP) GoogleMaps .

Description. Male. Bodycoloration greenish yellow ( Fig. 2 View Figs 2–11 ), only the head with black markings.

Head. Vertex with transverse black band departing from each eye, surrounding the ocelli and extending to the posterior area behind the eyes. Eyes rounded, slightly projecting laterally beyond anterior angles of pronotum. Lateral ocelli widely separated and laterally projected, higher than median ocellus in frontal view ( Fig. 6 View Figs 2–11 ). Postclypeus unstained, with ten transverse grooves. Central sulcus shallow and slender. Anteclypeus and carina tawny, apex half-moon shaped. Lorum with several silver setae ( Fig. 7 View Figs 2–11 ). Labium long, reaching the metacoxae ( Fig. 8 View Figs 2–11 ).

Thorax. Pronotum ( Fig. 6 View Figs 2–11 ) with lateral and sub-lateral lobes with wrinkles. Mesonotum ( Fig. 2 View Figs 2–11 ) with submedian andlateral sigillae slightly stained in pale green. Operculum ( Fig. 9 View Figs 2–11 ) broad, widely spacedbythe metacoxae, and laterally directed; posterior margin slightly convex, lateral margin very short. Meracanthus large, coveringthe internal angle of operculum in dorsal view. Proximal margins of metacoxae forming acute projections ( Fig. 8 View Figs 2–11 ). Wings hyaline. Fore wings ( Figs 2–3 View Figs 2–11 ): basal cell slightly smoky, twice as long as wide; posterior vein ofbasal cell arched; cubitus anterior vein slightly concave; cubital cell wider than clavus; medial cell twice as long as the ulnar cell 3, almost half of the length of fore wing; radius anterior vein closely aligned with subcosta for its length, divergent at apex; median vein long, reaching half thelength of radial cellproximal to M3+4 fork; apical cell 1 longer than any other apical cell.

Abdomen ( Fig. 2 View Figs 2–11 ) subcylindrical, fusiform, short, the length equal to the combined length of head and thorax in dorsal view. Timbals elongate laterally, posteriorly directed, anterior margin of the same length as anterior margin of tergite 1 ( Fig. 10 View Figs 2–11 ). Sternite VII subrectangular, with posterior margin concave and slightly emarginated; sternite VIII triangular ( Fig. 11 View Figs 2–11 ).

Genitalia ( Figs 12–14 View Figs 12–14 ). Pygofer distalshoulder undeveloped. Basal lobe of pygofer long, reaching uncus. Uncus long with setae, tapering to apex, thelateralmargins folding to aedeagus. Aedeagus broad, taperingto apex. Theca with ventral branches, apex of theca beak-shaped in lateral view, dorsally grooved and bifurcated on the anterior margin, with wrinkles. Vesica originating in a fissure from basal plate to the distal third of the theca. Apex of theca with two slender sclerotized branches closely spaced on the fissure of vesica.

Female ( Figs 15–18 View Figs 15–18 ). Same characteristics as in the male, but body a little more yellowish ( Fig. 15 View Figs 15–18 ). Operculum similar to that of the male, with the lateral margin very short and posterior margin slightly convex ( Fig. 16 View Figs 15–18 ). Meracanthus large, longer than operculum, covering the internal angle of operculum in dorsal view ( Fig. 16 View Figs 15–18 ). Sternite VII longer than any other, posterior margin with an obtuse middle groove reaching more than half of sternite, formingtwo lobes ( Fig. 17 View Figs 15–18 ). Lateral margins of abdominal segment 9 touching medially ( Fig. 17 View Figs 15–18 ). Ovipositor sheath shorter than tip of dorsal beak ( Fig. 18 View Figs 15–18 ).

Males (n = 3, values for the holotypein parentheses) lb 23.0–25.1 (25.1); wh 6.21–6.66 (6.48); lh 1.08–1.26 (1.17); wp 7.56–8.28 (8.28); lp 3.33–3.96 (3.96); wm 6.48–6.93 (6.93); lm 4.23–4.77 (4.77); lfw 31.1–34.6 (34.6); wfw 11.3–12.9 (12.9); lhw 18.3–20.3 (20.3); whw 7.7–8.8 (8.6).
