A new species of Pinndorama Domahovski (Hemiptera: Cicadellidae: Hyalojassini) from the Amazon Rain Forest, Brazil

. Pinndorama dilatata sp. nov. is described based on specimens from Amazonas State, Brazil. The genus is firstly recorded from the Brazilian states of Amazonas, Goiás, Maranhão, and São Paulo and a distribution map is provided, including new records to P. dianae, P. guartela, P. melanocephala, P. ronurensis, and P. pitanga. The key to males is updated to include the new species and minor improvements.


INTRODUCTION
The tribe Hyalojassini Evans, 1972 was revalidated by Dai et al. (2015) 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., 2015;Krishnankutty et al., 2016;Domahovski, 2021a, b, c;Yang & Dai, 2022).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., 2023).Their biology remains poorly known, however, these insects are known to feed on woody plants and shrubs (Krishnankutty et al., 2016).In South America, some species were recently reported feeding on plants of the families Asteraceae, Lauraceae, Melastomataceae, and Myrtaceae (Domahovski, 2021c).Among them, Pinndorama pitanga Domahovski, 2021 feeds on Eugenia uniflora L. and P. guartela on Myrcia hartwegiana (O.Berg) Kiaers, both belonging to Myrtaceae.(Domahovski, 2021c).Pinndorama Domahovski, 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 Momoria Blocker, 1979 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, 2021c).
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.
Morphological terminology follows Young (1968Young ( , 1977)), except for the head features (Hamilton, 1981;Mejdalani, 1998) and leg chaetotaxy (Rakitov, 1997).The use of the terms "pseudostyle" (thickened portion along the inner margin of the subgenital plate) follows Blocker (1979) and "gonoplac" (third valvula of ovipositor) follows Mejdalani (1998).Techniques used for genitalia dissection (male and female) follow Oman (1949), including few modifications described by Cavichioli & Takiya (2012).Verbatim label data are specified within quotation marks, with a backslash (\) separating the lines on the labels.Square brackets ([ ]) are used to supplement abbreviated information.The distribution map was compiled based on shape layers and terminology of Latin America and Caribbean ecological systems defined by Josse et al. (2003) in QGIS https://www.qgis.org/en/site.

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).

Distribution
Fig. 1 Pinndorama species are distributed across different biomes in South America (Fig. 1), such as the Cerrado savannah in Central Brazil, Amazonian and Atlantic rainforests, and moist Andean Forest, ranging in altitude from 0 to 1,500 m a.s.l.(Fig. 1).
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 mar-  gins 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.
