INTRODUCTION

The tribe Hyalojassini Evans, 1972 was revalidated by Dai et al. (2015Dai, W.; Dietrich, C.H. & Zhang, Y. 2015. A review of the leafhopper tribe Hyalojassini (Hemiptera: Cicadellidae: Iassinae) with description of new taxa. Zootaxa, 3911(1): 1-42. 10.11646/zootaxa.3911.1.1.

) from a synonymy under Iassini Walker 1870. The group is currently the third largest of the twelve tribes of Iassinae, comprising 40 genera and 161 species distributed in Southeast Asia (nine genera and 35 species) and the Americas (31 genera and 126 species) (Dai et al., 2015Dai, W.; Dietrich, C.H. & Zhang, Y. 2015.

). In the Americas, a proportion of approximately 86.5% of species are distributed in the Neotropical and 15% in the Nearctic region (pers. obs.). The Brazilian fauna currently comprises 15 genera and 32 species, with most species occurring in the Atlantic Forest (Takiya et al., 2023Takiya, D.M.; Cavichioli, R.R.; Mejdalani, G.; Felix, M.; Gonçalves, C.C.; Camisão, B.M.; Barbosa, J.F.; Prando, J.S.; Quintas, V.M.C.; Pecly, N.H.; Guimarães, D.L.P. & Domahovski, A.C. 2023.

). Their biology remains poorly known, however, these insects are known to feed on woody plants and shrubs (Krishnankutty et al., 2016Krishnankutty, S.M.; Dietrich, C.H.; Dai, W. & Siddappaji, M.H. 2016. Phylogeny and historical biogeography of leafhopper subfamily Iassinae (Hemiptera: Cicadellidae) with a revised tribal classification based on morphological and molecular data.

https://doi.org/10.1111/syen.12175...
). In South America, some species were recently reported feeding on plants of the families Asteraceae, Lauraceae, Melastomataceae, and Myrtaceae (Domahovski, 2021cDomahovski, A.C. 2021c.

was recently described to include eight species from Brazil, Paraguay, and Peru, being currently the fourth largest genus in Hyalojassini, only behind the Oriental genus Trocnadella Pruthi, 1930 with 10 species, and the American Penestragania Beamer & Lawson, 1945 with 14 species and MomoriaBlocker, 1979Blocker, H.D. 1979. The Iassinae (Homoptera: Cicadellidae) of the western Hemisphere. Journal of Kansas Entomological Society, 52(1): 1-70. with 29 species. The genus is recognized by forewings with appendix and first apical cell wide, more membranous than adjacent cells and with vein separating appendix and first apical cell, evanescent apically; male sternite VIII longer than VI and VII combined, and completely hiding the ventral portion of pygofer; pygofer without processes and lateral lobe without macrosetae; subgenital plate with well developed pseudostyle and with external margin enfolding laterally the anteroventral portion of pygofer; connective amorphous; and style long, with apex curved dorsally (Domahovski, 2021cDomahovski, A.C. 2021c. A new South American genus and eight new species of Hyalojassini (Hemiptera: Cicadellidae: Iassinae) with additional records of host plants.

https://doi.org/10.1080/00222933.2021.19...
).

Among the Neotropical genera of Hyalojassini, Pinndorama is most closely related to Garlica Blocker, 1976, Gehundra Blocker, 1976, Grunchia Kramer, 1963, Jivena Blocker, 1976, Maranata Blocker, 1979, and Penestragania Beamer & Lawson, 1945, due to the following combination of characters: subgenital plate present and well developed; pseudostyle present; connective absent; and style long, approximately straight and placed vertically in relation to pygofer axis. In relation to these genera, Pinndorama shares with Garlica, Gehundra, Grunchia, and Jivena the male sternite VII long, extending to the apex of pygofer, but can be distinguished in having forewing with vein separating appendix and first apical cell evanescent apically and male pygofer lacking macrosetae.

In this work, a new species is described, the key to males is updated, and a distribution map is presented for Pinndorama including new records to Brazilian states.

Description

Coloration: Head and thorax (Fig. 2A-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)Domahovski, A.C. 2021c. A new South American genus and eight new species of Hyalojassini (Hemiptera: Cicadellidae: Iassinae) with additional records of host plants.

.

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).
