Type species.

Propincurtara longilinea sp. nov.

Diagnosis.

Elongated leafhoppers, medium to large size (11.1-13.6 mm). Head, in dorsal view (Fig. 44A), produced anterad, median length longer than half interocular width; crown surface with inconspicuous oblique striae between ocelli; in lateral view (Fig. 44C), crown-face transition thin; antennal ledge (Fig. 44B, C) indistinct, continuous to crown margin. Pronotum (Fig. 44A) with black punctures. Forewing (Fig. 44D) without accessory vein on external discal cell. Valve (Fig. 44G) without pair of oblique integument thickening. Metatarsomere I (Fig. 3S) plantar surface with outer row indistinct and inner row formed by several short and juxtaposed setae. Metatarsomere II (Fig. 3S) with platellae flanked by one inner and one outer tapered setae. Aedeagus (Fig. 44L, M) with apodemal processes; preatrium with pair elongated processes produced ventrally. First valvula (Fig. 45C, D) dorsal margin sinuous apically. Second valvula (Fig. 45E, F) with dorsal protuberance inconspicuous and truncated, located at half length of valvula; ventral margin with denticles apically.

Coloration.

Head and thorax (Fig. 44A-D, 46A, B) yellowish brown. Pronotum (Fig. 44A) with dark punctures. Forewing (Fig. 44D) with scattered dark maculae.

Description.

Head, in dorsal view (Fig. 44A), produced anterad, median length longer than half interocular width; transocular width 8.5 tenths of humeral width of pronotum; anterior margin subtriangular; crown surface with inconspicuous oblique striae between ocelli; ocellus equidistant between anterior and posterior margins of crown and equidistant between midline and inner margin of eye. Head, in frontal view (Fig. 44B), face approximately as wide as high; frons 1.9 × longer than wide, surface just below the crown-face transition not excavated; frontogenal suture distant from eye margin by slightly less than maximum width of clypeus and surpassing antennal ledge, extending to anterior margin of crown; antennal ledge continuous to lateral margin of crown; gena with ventrolateral margin rounded and slightly angled medially; maxillary plate produced ventrally as far as clypeus apex; clypeus 1.4 × longer than wide, lateral margins straight and parallel, apex straight and carinated. Head, in lateral view (Fig. 44C), crown-face transition foliaceous, texture smooth medially and with few striae near of eye; frons and clypeus not inflated. Pronotum, in dorsal view (Fig. 44A), with transverse striae on the disc and posterior third; lateral margin slightly shorter than eye length; posterior margin slightly excavated; in lateral view (Fig. 44C), moderately declivous, continuous with head declivity. Mesonotum (Fig. 44A) as long as wide. Scutellum (Fig. 44A) almost flat. Forewing (Fig. 44D) 3.5 × longer than wide, venation distinct; M vein with segment after the divergence between R+M and before the cross vein m-cu 1, 4 × longer than the length of m-cu 1; external discal cell lacking inner-apical extra numeric vein; appendix narrow and bordering first to second apical cells; apex rounded. Profemur 4 × longer than wide; AD, AM, and PD rows reduced and poorly defined, with exception of apical setae AD1, AM1, and PD1, respectively; AV and PV rows formed by 5-6 and 4-5 setae respectively; IC row formed by slightly arched comb of fine setae, beginning at distal half of femur and extending to AM1. Protibia, in cross-section, semi-circular, with longitudinal carinae adjacent to PD row; AV row formed by long setae, slightly longer and thicker towards apex; dorsal rows with apical AD1 and PD1 setae developed; AD row without differentiated setae; PD row with 4-5 setae; PV row with 6-7 longer setae and undifferentiated intercalary setae. Metafemur with setal formula 2:2:1. Metatibia PD, AD, and AV rows with 25-26, 13-14, and 16-18 macrosetae, respectively; AD row without intercalary setae between macrosetae; PV row with setae of apical half formed by sequence of a thicker and 2-4 thinner setae, ending with a thick seta. Metatarsomere I (Fig. 3S) elongated, approximately 4 × longer than wide at apex; ventral surface with outer row indistinct and inner row formed by several short and juxtaposed non-cucullate setae; apex with 6-7 platellae, flanked by one inner and one outer tapered seta. Metatarsomere II apex with 3 platellae, flanked by one inner and one outer tapered seta.

Male terminalia.

Pygofer (Fig. 44G) without processes. Valve (Fig. 44F) without pair of oblique integument thickening. Connective (Fig. 44I) D-shaped; stem with lateral margins weakly sclerotized. Aedeagus (Fig. 44L, M) with apodemal processes; preatrium bearing pair of uncommonly elongated processes directed ventrad.

Female terminalia.

First valvula (Fig. 45C, D) dorsal margin sinuous apically. Second valvula (Fig. 45E, F) with dorsal protuberance inconspicuous and truncated, located at half length of blade; ventral margin with denticles apically.

Distribution.

Brazil.

Etymology.

The genus name is feminine and combines the Latin word ʻpropinquusʼ (near, close) with Curtara, a superficially similar genus of Gyponini .
