Figs. 2 , 3

Diagnosis: Yellow leafhoppers ( Fig. 2A, B ) with forewing bearing one pair of small black spots at midlength and apical portion smoky. Style ( Fig. 2J ), in lateral view, with dorsal margin expanded subapically; apex forming a small claw-like process curved dorsally.

Measurements (mm): Total length: Holotype, male: 4.0. Paratypes, female (n = 2): 7.9-9.1.

Description

Coloration: Head and thorax ( Fig.2 A-C) uniformly yellow without maculae. Forewing ( Fig. 2A, B ) translucent pale yellow with black setae; one pair of small black spots at midlength: one at clavus and one near apex of inner discal cell; apex of clavus, base of appendix, apex of anteapical cells, and apical cells, smoky. Metatibia ( Fig. 2A, B ) with cucullate bases of macrosetae black. Pygofer with apex red.

External morphology: Features as in the genus description of Domahovski (2021c).

Male terminalia: Sternite VIII ( Fig. 2D ) slightly tapered apically; posterior margin rounded, slightly emarginated and weakly sclerotized at middle. Pygofer ( Fig. 2E, F ), in lateral view, with dorsal margin deeply notched medially; ventral margin broadly rounded near base, with small setae, straight medially, slightly curving dorsally near apex and bearing few moderately long filiform setae; apex broad and slightly concave; in ventral view ( Fig. 2G ), lateral margins carinated; few short setae near base, on lateral carina, and forming small group subapically on inner portion of lateral margin. Subgenital plate ( Fig. 2E, F, H ) with apodeme short, weakly extending dorsally; inner margin with some striae; external margin strongly developed laterally, rounded; pseudostyle thin, straight, produced ventrally, with group of setae near apex. Style ( Fig. 2E, I, J ) slender and straight, positioned perpendicular relative to pygofer; in lateral view ( Fig. 2J ), posterior (dorsal) margin expanded subapically; apex forming a small claw-like process curved posterad. Aedeagus ( Fig. 2K, L ) dorsal apodeme shorter than shaft, lateral margins, in caudal view, near base expanded laterally forming pair of subtruncated lobes, apex, in lateral view, rounded; shaft moderately thin, slightly curved dorsally, weakly expanded medially;apex tapered, acute; in ventral view, distal portion deeply clefted. Other characteristics as in generic description.

Female terminalia: Sternite VII ( Fig. 3A ) 2x wider than long; posterior margin slightly excavated laterally of small rounded median lobe, which occupies median third and is produced posteriorly as far as lateral angles. Pygofer ( Fig. 3B, C ) with ventral margin broadly rounded; apex slightly excavated; lateral surface with short setae on ventral half; apex with few thicker setae. First valvifer ( Fig. 3D ) rectangular; fused to each other by a narrow sclerotized extension of anteroventral margin. First valvula ( Fig. 3D ) with dorsal and ventral margins almost parallel; ventral interlocking device long, extending over basal two-thirds; dorsal sculptured area areolate not reaching dorsal margin; apical portion ( Fig. 2E ) gradually tapered and acute. Second valvifer ( Fig. 3H ) about 3x higher than long; with median posterior finger-like projection. Second valvula ( Fig. 3F, G ) with three distinct widely spaced teeth; apex with dorsal and ventral margins with denticles. Gonoplac ( Fig. 3H ) dorsoapical margin long, with half length of gonoplac; external surface without dentiform cuticular projections, with few short setae on median portion of ventral margin; apex narrowly rounded.

Etymology: The new species name "dilatata ″ refers to the style broadened subapically.

Material examined

Holotype male: " BRASIL: Amazonas , Barcelos , \ Rio Padauari,Com.Ararão/ Ararinha \ 00.50487°N, 064.05831°W \ 04.VI.2010 light \ Cavichioli & Takiya leg.″ ( INPA).

Paratypes: 2♀, same data of holotype ( INPA, DZRJ).

Remarks: The new species is most similar to P. dianae in having similar coloration ( Fig. 2A ), subgenital plate triangular, with pseudostyle short and thin ( Fig. 2H ), and aedeagus, in lateral view, tapering to acute apex ( Fig. 2K ). However, P. dilatata sp. nov. can be easily separated by its pygofer with ventral margin straight ( Fig. 2F ), subgenital plate with longer pseudostyle ( Fig. 2H ), style broadened subapically ( Fig. 2J ), aedeagus, in lateral view, with shaft broader ( Fig. 2K ), and female sternite VII produced posteriorly as far as lateral angles ( Fig. 3A ).
