Camisão, Beatriz M. & Takiya, Daniela M., 2017, Two new species of Bahita Oman, 1938 from Central-Western Brazil (Insecta: Hemiptera: Cicadellidae: Deltocephalinae), Zootaxa 4281 (1), pp. 198-206 : 204-205

Bahita zanolae sp. nov.

(Figs. 11–20)

Type-locality. Caiapônia, GO, Brazil.

Length. Male, 6.0 mm.

Coloration. Body (Figs. 11, 12) light brown dorsally and ventrally; with dark brown maculae ventrally. Crown with two maculae on anterior margin, a discontinuous transverse stripe between frontogenal sutures, and six maculae on discal portion between eyes near posterior margin, dark brown. Frons (Fig. 13) dark brown; with lateral and superior margins, paired parallel transverse stripes, and median macula near clypellar suture, light brown. Clypellus dark brown; with median light yellow arrow-shaped macula. Gena light brown; with region from midlength of mesal margin of eye to posteroventral margin of eye, dark brown. Lorum dark brown; with large light brown macula. Pronotum (Fig. 11) light brown, irrorate with dark brown. Forewing (Figs. 11, 12, 14) translucent yellow; veins dark brown; outer anteapical cell and apical cells between R1 and third apical cell transparent; dark brown macula over R1, apical region of second discal cell, central anteapical cell and third costal cell; small dark brown blurred maculae inside cells in clavus and corium.

External morphology. Head (Figs. 11, 12) short; parallel margined; transocular width slightly greater than pronotum width; coronal suture visible, reaching past 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. 12) convex in lateral view; transition of crown to face angled; texture of anterior margin of head transversely striate. Ocellus (Fig. 13) medium sized; close to eye, on anterior margin. Antennal bases near posteroventral corners of eyes. Eye with mesal margin entire. Frons longer than wide. Clypellarl suture arcuate. Clypellus widening apically; relatively flat, following natural curve of genae. Lorum wider than clypellus near base; close to lower genal margin. Pronotum (Fig. 11) without transverse striations. Forewing (Figs. 11, 12, 14) with inner anteapical cell open; outer anteapical cell truncate apically; vein R1 diverging basad of R fork; with one or two supranumerary reflexed costal veins; with one crossvein between A1 and claval suture and one crossvein between A1 and A2. Hindwing without pigmentation. Profemur with AM1 seta only; 16 setae on intercalary row; row AV with 22 short and stout macrosetae, with two apical setae, AV1 seta well differentiated from intercalary row setae. Protibia row AD with one macroseta; row PD with four macrosetae. Other characters as in the generic description.

Male genitalia. Pygofer (Figs. 15, 16) with macrosetae distributed into several rows; dorsoapical processes on the inner surface, curved outwards; posterior margin truncate. Subgenital plate (Figs. 15, 17), in lateral view, extending farther beyond apex of pygofer; outer margins somewhat concave in ventral view; macrosetae uniseriate laterally; with long fine setae; apex rounded. Connective (Fig. 18) with stem longer than anterior arms; anterior arms parallel. Style (Fig. 18) preapical lobe short and rounded; apophysis smooth, curved outwards; apex unciform. Aedeagus (Figs. 19, 20) long and slender; preatrium absent; shaft with pair of apical processes bifurcate into slender and divergent rami, basal rami straight and longer than apical one (in holotype, basal ramus from right side broken), apical rami straight, in caudal view almost parallel; gonopore apical. Segment X (Fig. 16) sclerotized laterally and dorsally.

Female terminalia. Female unknown.

Etymology. This species is named after Prof. Keti Maria Zanol (Universidade Federal do Paraná), former student of Prof. Sakakibara, and specialist on deltocephaline lesfhoppers, who described nineteen species of Bahita and several other Bahitini.

Notes. Bahita zanolae sp. nov. can be distinguished from all other species of Bahita by the following set of characters: (1) forewings with transparent region over outer anteapical cell, apical cells between R1 and third apical cell, and dark brown pigmentation over R1, apical region of second discal cell, central anteapical cell and third costal cell; (2) pygofer subquadrate, with dorsoapical processes on inner surface, curved outwards; and (3) aedeagus with pair of apical processes, each bifurcate into slender and divergent rami, basal rami longer than apical ones.
