Neopsis campestris sp. nov.

Figs. 1-21

Diagnosis: Head ( Figs. 3, 4 ) bright yellow with transverse red band between eyes; frons and clypeus black in males and bright yellow in females ( Fig. 13 ); ventral margin of male pygofer ( Figs. 5, 6 ) with short preapical process, acute and curved dorsally; style ( Fig. 8 ) narrow, preapical lobe moderately developed, not strongly produced posterad; posterior margin of aedeagus ( Figs. 9-10 ) with well developed triangular lobe sub basally; apex ( Fig. 10 ) with weak lateral serrations and without lateral processes.

Measurements (mm): Holotype (♂): total length 4.7. Paratypes (♂), 4.7-4.8; (♀), 5.1-5.5.

Color: Head(Figs.3,4,12,13)brightyellowwithtransversered band between eyes;frons and clypeus black in males ( Fig.4 ) and bright yellow in females ( Fig. 13 ). Pronotum ( Figs. 2 , 11 ) 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.

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).

Female terminalia: Sternite VII ( Figs. 14-16 ) lateral margins slightly tapered posterad and culminating in pair of slender, short processes; posterior margin approximately straight between processes with shallow medial v-shaped notch. Pygofer ( Figs. 15-16 ) moderately long; with few macrosetae near ventral margin and anteroventral portion; apex with pair of short and rounded lateral lobes. Ovipositor ( Figs. 15-16 ) slender, evenly curved; apex extended slightly beyond pygofer in repose. First valvifer ( Fig. 17 ) small and triangular-shaped. First valvula ( Fig. 17 ) with ventral interlocking device distinct on basiventral half of blade; apex ( Fig. 18 ) gradually tapered and acute. Second valvula ( Fig. 19 ) dorsal margin with approximately 18 teeth; apex ( Fig. 20 ) with ventral margin with denticles. Second valvifer ( Fig. 21 ) elongated, ca. 3,5 times higher 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).

Etymology: The specific epithet refers to the native grasslands of Southern Brazil where the type series was collected.

Material examined

Holotype male: “ Brasil, Paraná, Tibagi \ P.[Parque] E.[ Estadual ] do Guartelá , 1000 m \ 24°33′47″S 50°15′26″W \ 21-24.XI.2016 Sweep \ A.C. Domahovski leg.” (DZUP).

Paratypes: 7 ♂♂, 10 ♀♀, same data of holotype (2 ♂♂, 2 ♀♀, DZRJ; 1 ♂, 1 ♀, MZSP; 4 ♂♂, 7 ♀♀, DZUP) ; 1 ♀, same data as preceding, except “ 23-24.II.2017 Luz” ( DZUP) .

Notes: The new species keys out at couplet 7 in Takiya & Dietrich’s (2017) key. Distinctive features of N. campestris sp. nov. include the bright red pronotal margins; the body length <5.0 mm (males); the style with preapical lobe weakly developed, not distinctly produced posterad; and the posterior margin of atrium of aedeagus with a large lobe. However, the new species can be separated from N. villaricensis Takiya & Dietrich, 2017 in lacking the dorsal spine near base of aedeagal shaft and lacking apical triangular processes. Neopsis campestris sp. nov. differs from N. robusta Linnavuori, 1965 in having the male pygofer with a short preapical process, acute and curved dorsally; and aedeagus with a well developed triangular lobe on the posterior margin.
