description: Pinndorama dilatata sp. nov.
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).
