Paladini, Andressa, Cavichioli, Rodney Ramiro & Carvalho, Gervásio Silva, 2016, A new spittlebug species of Deois (Pandysia) (Hemiptera, Cercopidae, Ischnorhininae) with a key to species of the subgenus, Revista Brasileira de Entomologia 60 (3), pp. 214-216 : 216

Deois (Pandysia) paschoali sp. nov.

Figs. 1–10

Measurements (mm). (range in mm males/females): body length: 5.6–6.5/6.1–7.0. Length of tegmina: 4.5–5.3/4.8–5.7. (holotype): body length: 6.5 length of tegmina: 5.2

Diagnosis

General coloration black, tegmina with two yellow spots at base of posterior third; pygofer with a rounded process between anal tube and subgenital plates; spine of paramere with a truncate and serrate apex; aedeagus cylindrical, long and slender, C-shaped in lateral view with dorsal margin serrate distally.

Description

Head black; compound eyes brown, rounded, arranged transversely; vertex smooth and rectangular, lacking median carina; ocelli red, closer to each other than to compound eyes; tylus smooth and rectangular, lacking median carina; antennae yellow, pedicel sparsely setose, basal body of flagellum ovoid with one arista shorter than pedicel; postclypeus black, inflated, convex in profile, with one longitudinal carina slightly marked, lateral grooves slightly marked; rostrum extending to base of mesocoxae. Thorax black; pronotum hexagonal, not curved, anterior margin straight, anterolateral margins straight, posterolateral margin slightly sinuous, posterior margin slightly grooved; scutellum with slight central concavity, with horizontal grooves slightly marked; tegmina black with two yellowish spots at base of posterior third: first one on costal margin and second one near apex of clavus, former larger than latter, apical reticulation poorly developed; hindwing hyaline with brown venation, vein Cu1 thickened at base; legs black with two lateral spines (basal spine equal in size to spines in apical crown; apical spine larger than spines in apical crown); apical crown of spines on tibia consisting of two rows; basitarsus with one row of spines covered by long setae; subungueal process present and triangular. Abdomen: black.

Male. Pygofer black, with one rounded process between anal tube and subgenital plates ( Fig. 3 ); subgenital plates free for almost all their extension, each with truncate apex slightly convergent ( Fig. 4 ); paramere in lateral view with dorsal margin greatly humped, apex elongate with a truncate and serrate spine ( Fig. 7 ); aedeagus cylindrical, long and slender, curved dorsally C-shaped in lateral view, with apex and apical and median third of dorsal margin serrate ( Figs. 5 and 6 ).

Female. Ovipositor with first valvula long and slender with acute apex, one basal ventral process well developed, elongate, spoon-like directed downwards ( Figs. 8 and 9 ); second valvulae long, with dorsal margin smooth ( Fig. 10 ); third valvulae short and wide, with long ventral setae.

Remarks. The new species differs externally from other congeners by its black coloration with two yellowish spots on the tegmina. The shape of the paramere ( Fig. 7 ) is similar to D. schach and D. transiens , but its truncate and serrate apical spine is unique.

Etymology. The species name is in honor of Paschoal Coelho Grossi (Universidade Federal Rural de Pernambuco), beetle specialist and collector of Cercopidae .

Examined material. Holotype (male). Brazil, Paraná, Tijucas do Sul, Morro do Araçatuba 1200–1600 m 25–27.II.2011, P.C. Grossi leg. ( DZUP) . Paratypes: 3 males and 9 females with same data as holotype (1 male 3 females MCTP; 1 male, 5 females DZUP; 1 male 1 female BMNH) .
