A new species of Neopsis (Hemiptera: Cicadellidae: Tartessinae), with new distribution records from Paraná State, Brazil

Neopsis campestris sp. nov. is described and illustrated based on male and female specimens collected on native grassland at the Guartelá State Park, Paraná State, Southern Brazil. New distribution records are presented for three previously known species, Neopsis aurea Takiya & Dietrich, 2017, Neopsis myrceugeniae Takiya & Dietrich, 2017 and Neopsis robusta Linnavuori, 1965, representing the first known records of the subfamily Tartessinae for Paraná State. A distribution map is also provided to illustrate the locality data of specimens studied herein.

Neopsini currently comprises two genera, Lonnia Hamilton, 1983, with two species from Chile, and Neopsis Oman, 1938, which includes eleven previously described species distributed from the Caribbean islands to Southeastern Brazil (Takiya & Dietrich, 2017). Members of the tribe are rarely collected, and the few known species are scarce in zoological collections. Information on the life history and host plant associations for this group are still unknown. In Brazil, Neopsis was recently recorded in the Amazonian region, Cerrado and montane Atlantic forest (Takiya & Dietrich, 2017). This paper provides the first distribution records of four tartesine species for Paraná State, Southern Brazil ( Fig. 1), representing three previously described species, Neopsis aurea Takiya & Dietrich, 2017, Neopsis myrceugeniae Takiya & Dietrich, 2017and Neopsis robusta Linnavuori, 1965, and a new species, Neopsis campestris sp. nov. These are also the first tartesine species to be collected in the Araucaria moist forest and the native grasslands of the Brazilian Atlantic forest. Morphological terminology follows Dietrich (2005), except in the following terms: frons, clypeus and gonoplac (= third ovipositor valvula), which follows Mejdalani (1998). Techniques used for the dissection of the male genitalia follow Oman (1949), with a few modifications described in Cavichioli & Takiya (2012). Illustrations were prepared according to the procedures outlined in Domahovski & Cavichioli (2019). The distribution map was generated using the online tool SimpleMappr (Shorthouse, 2010). Labels were transcribed between quotation marks, with a backslash (\) indicating line breaks. with lateral and posterior margins and midline broadly red, contrasting with disc, cyan. Scutellum and exposed part of mesonotum (Figs. 2, 11) bright yellow. Ventral side of thorax, abdomen and legs yellow. Forewings (Figs. 2, 3, 11, 12) with three orange longitudinal bands, one along commisural margin and base of clavus, one along claval suture and one medially on corium, areas between bands cyan; veins cyan; distal third of membrane brown. Abdominal tergum brown or black in males and yellow in females.

Specimens
Description: External morphological characters as in the genus description of Takiya & Dietrich (2017).
Male terminalia: Male pygofer (Figs. 5, 6) relatively long, dorsal and ventral margin almost parallel; ventral margin with short preapical process, acute and dorsally curved; apex slightly tapered, rounded, dorsal margin bearing several minute tooth-like processes. Subgenital plates (Figs. 5-7) as long as pygofer; lateral constriction well developed; ventral surface with many setae. Style (Fig. 8) narrow, with preapical lobe moderately developed, but not strongly produced posterad; apophysis distad of lobe sinuate and denticulate, toe of foot-like apex rounded and weakly sclerotized; group of lateral setae present just distad of lobe. Connective (Fig. 8) with median anterior lobe well produced anterad of lateral arms. Aedeagus (Figs. 9, 10), in lateral view, with atrium narrow; posterior margin with well developed triangular lobe subbasally and few small setae just above of lobe; shaft relatively short; apex (Fig. 10), in dorsal view, with weak lateral serrations and without lateral processes. Other characters as in generic description of Takiya & Dietrich (2017). than long. Gonoplac (Fig. 21) with dorsoapical margin long, straight, almost parallel to ventral margin; ventral margin broadly rounded, with spaced setae near ventral margin; external surface with dentiform cuticular projections near apex and ventral margin; apex rounded. Other characters as in generic description of Takiya & Dietrich (2017).

Notes on distribution, collecting methods and color variation in N. robusta
This study provides the first records of the subfamily Tartessinae for Paraná State, Brazil, which now represent the southernmost records for the genus Neopsis (Fig. 1).
N. aurea and N. robusta are also recorded, for the first time, in the Brazilian Atlantic Forest and the Araucaria moist forest, in the municipality of São José dos Pinhais. Neopsis myrceugeniae was collected in three different municipalities, São José dos Pinhais (Araucaria moist forest), Palmas (Native Grassland), and Tibagi (Parque Estadual do Guartelá), which encompasses native grassland, Cerrado and fragments of Araucaria moist forest. Neopsis campestris sp. nov. was collected only in Tibagi by sweeping shrubs and grasses. Neopsis aurea, N. myrceugeniae and N. robusta were mainly collected by sweeping in the understory of the forest, and a few specimens were collected using malaise or light traps.
The males of N. robusta studied herein (Fig. 24) do not have a dark to black scutellum, as observed in specimens from Bolivia and Ecuador. However, several other features, such as the morphology of male genitalia, the shape of the posterior margin in the female sternite VII, overall body size, and coloration match the description and illustrations of this species. Therefore, the color of the scutellum will be assumed as intraspecific variation in this study.
