Bahita sakakibarai sp. nov.

(Figs. 1–10)

Type-locality. Alto Paraíso de Goiás, GO, Brazil.

Length. Males, 4.6–4.8 mm.

Coloration. Body (Figs. 1, 2) dark brown dorsally and ventrally. Crown with the anterior region, two pairs of maculae near lateral margins of eyes, and one on median portion of discal region, ivory; discal region with pair of orange to brown maculae. Frons (Fig. 3) dark brown, with several paired parallel light brown transverse stripes; pair of maculae on lateral margins between ocelli and antennal bases, ivory. Clypellus dark brown. Gena dark brown, with one ivory macula on lateral margin of eye and light brown macula near lorum. Lorum dark brown, with median light brown macula. Pronotum (Fig. 1) dark brown; irrorate with light brown; at least one pair of ivory maculae on anterior margin. Mesonotum (Fig. 1) dark brown; scutum with one pair of lateral ivory margins and one pair of orange median maculae (not present on all specimens); scutellum with five maculae, pair on lateral margins and one at apex, ivory, and orange pair on median region. Forewing (Figs. 1, 2, 4) translucent yellow; with scattered transparent fenestra; veins dark brown. Profemur and mesofemur dark brown; with apices light brown. Protibia and mesotibia light brown. Metatibia dark brown; dorsal region light brown. Tarsomeres with basal half dark brown and apical half light brown.

External morphology. Head (Figs. 1, 2) short; parallel margined; transocular width slightly greater than pronotum width; coronal suture visible, reaching past the midlength of crown; crown not produced, width less than twice width of eyes; median length subequal to length next to eyes; frontal region transversely sulcate; discal portion of crown glabrous; anterior region (Fig. 2) convex in lateral view; transition of crown to face angled; texture of anterior margin of head shagreen. Ocellus medium sized; close to eye, on anterior margin (Fig. 3). Antennal bases near posteroventral corners of eyes. Eye with mesal margin entire. Frons longer than wide. Clypellar suture arcuate. Clypellus widening apically; relatively flat, following natural curve of genae. Lorum slightly wider than clypellus near base; close to lower genal margin. Pronotum (Fig. 1) without transverse striations. Forewing (Figs. 1, 2, 4) outer anteapical cell truncate apically; vein R1 diverging basad of R fork; with two supranumerary reflexed costal veins; with one crossvein between A1 and claval suture and two crossveins between A1 and A2. Hindwing without pigmentation. Profemur with AM1 seta only; 17–19 setae on intercalary row; row AV with 23–24 short and stout macrosetae, with two apical setae, AV1 seta well differentiated from intercalary row setae. Protibia row AD with only one macroseta; row PD with four macrosetae. Metatarsomere I with inner apical seta of pecten acuminate. Other characters as in the generic description.

Male genitalia. Pygofer (Figs. 5, 6) with macrosetae distributed into several rows; dorsoapical processes on the inner surface, curved inwards and crossing each other in caudal view; posterior margin rounded. Subgenital plate (Figs. 5, 7), in lateral view, extending slightly beyond apex of pygofer; with outer margins concave in ventral view; macrosetae uniseriate laterally; with long fine setae; apex rounded. Connective (Fig. 8) with stem longer than anterior arms; anterior arms somewhat parallel. Style (Fig. 8) with preapical lobe short and subquadrate; apophysis smooth, slightly curved outwards; apex truncate. Aedeagus (Fig. 9, 10) long and slender; preatrium absent; shaft with pair of apical processes bifurcate, apical rami longer and straight, basal rami shorter and curved anteriorly; gonopore apical. Segment X (Fig. 6) sclerotized laterally and dorsally.

Female terminalia. Female unknown.

Etymology. This new species is named after Prof. Albino M. Sakakibara (Universidade Federal do Paraná), a great Auchenorrhyncha taxonomist, who trained specialists on many different groups of leafhoppers, treehoppers, and spittlebugs.

Notes. The new species is similar to B. bicrura , B. interjecta , and B. zanolae sp. nov., as they all have processes on the dorsal margin of the male pygofer. However, B. sakakibarai can be differentiated by the dorsal processes curved inwards and crossing each other in caudal view. The aedeagus of the new species resembles that of B. zanolae sp. nov., B. furcifer , and B. interjecta as they all have paired bifid apical processes. However, B. sakakibarai sp. nov. has a shorter aedeagus and the basal rami of the apical processes are curved. Bahita sakakibarai sp. nov. can be distinguished from all the other species of the genus by the following set of characters: (1) crown dark brown with anterior region and five maculae on discal region ivory, and with a pair of orange maculae; (2) forewings translucent with dark brown veins and dispersed transparent maculae; (3) male pygofer with dorsal processes on inner surface, curved inwards and crossing each other in caudal view; (4) style preapical lobe short and subquadrate and apex truncate; and (5) aedeagus with pair of apical processes, each bifurcate with apical rami longer and straight and basal rami shorter and curved.
