( Figs 1–4 View FIGURE 1 View FIGURE 2 View FIGURE 3 View FIGURE 4 , 7 View FIGURE 7 )
Type locality. Brazil, Roraima State, ESEC Maracá. Description. Body length. Male ( Fig. 1A View FIGURE 1 ), 2.9 mm; Female ( Fig. 1B View FIGURE 1 ), 4.4 mm .
Color. Males ( Figs 1A View FIGURE 1 , 2A–C View FIGURE 2 ). Body mainly black with some regions yellowish-brown. Vertex, pronotum, and mesonotum yellowish-brown with broad median longitudinal white stripe crossing these structures ( Figs 1A View FIGURE 1 , 2B View FIGURE 2 ). Forewing with corium mostly black with apex light brown and two small circular pale maculae in between corium and clavus, one at base and another near midlength of claval suture; clavus brown ( Fig. 2B, C View FIGURE 2 ). Legs mostly yellow; metafemur black ( Fig. 2B, C View FIGURE 2 ). Abdominal tergites with dorsal median pair of small and conspicuous yellow maculae ( Fig. 2B View FIGURE 2 ); lateral white maculae of abdominal sternites in lateral view smaller and fainter ( Fig. 2C View FIGURE 2 ); and thoracic and abdominal sternites mostly white medially ( Fig. 2A, C View FIGURE 2 ).
Females ( Figs 1B View FIGURE 1 , 2D–F View FIGURE 2 ). Body mainly brown with some regions light brown. Vertex, pronotum, and mesonotum light brown with lighter brown broader median longitudinal stripe crossing these structures ( Fig. 2E View FIGURE 2 ). Forewing hyaline brown ( Fig. 2E View FIGURE 2 ). Legs brown ( Fig. 2F View FIGURE 2 ). Abdomen with tergite III with lateral white macula ( Figs 1B View FIGURE 1 , 2F View FIGURE 2 ); all tergites with median longitudinal broad light brown stripe ( Fig. 2E View FIGURE 2 ).
Structure. Head and thorax. Vertex ( Fig. 2B, E, H View FIGURE 2 ) with anterior margin slightly pointed; anteriorly converging to rounded apex; slightly longer than basal width at midline; longer than pronotum length at midline. Frons ( Fig. 2A, D, G View FIGURE 2 ) with median carina which does not reach fastigium, weak in males and conspicuous in females; in lateral view ( Fig. 2C, F, I View FIGURE 2 ), each side with row of eight sensory pits bordering sublateral carina, four pits bordering frontogenal carina, and a pair of pits bordering fastigium (linking the other two rows providing a triangle-like arrangement—with three isolated pits within, aligned diagonally).
Pronotum ( Fig. 2B, E, H View FIGURE 2 ) with six sensory pits bordering lateral margins of disc and a group of fiver inner ones at posterior half. Mesonotum ( Fig. 2B, E, H View FIGURE 2 ) with median carina; region outerad of lateral carina with eight to ten sensory pits.
Abdomen. Tergite III ( Figs 2C, F View FIGURE 2 , 7 View FIGURE 7 ), in lateral view, with one to two sensory pits (two in holotype). Tergites IV ( Fig. 2C, F View FIGURE 2 , 7 View FIGURE 7 ), in lateral view, with one row of two to three sensory pits (three in holotype) followed by an isolated ventral pair. Tergites V ( Fig. 2C, F View FIGURE 2 , 7 View FIGURE 7 ), in lateral view, with one row of three sensory pits (three in holotype) followed by an isolated ventral pair. Tergites VI ( Fig. 2C, F View FIGURE 2 , 7 View FIGURE 7 ), in lateral view, with one row of three sensory pits (three in holotype) followed by an isolated ventral pair. Tergites VII ( Fig. 2C, F View FIGURE 2 , 7 View FIGURE 7 ), in lateral view, with one row of two to three sensory pits (three in holotype) followed by an isolated ventral pair. Tergite VIII ( Fig. 7 View FIGURE 7 ), in lateral view, with one to two sensory pits (two in holotype).
Male terminalia. Pygofer ( Fig. 3A View FIGURE 3 ) with anterior margin concave; posterior margin with concavity on ventral half. Connective ( Fig. 3B View FIGURE 3 ) with tectiform structure bearing tectiductus; ventral support inverted Y-shaped. Gonostylus ( Fig. 3D View FIGURE 3 ) hook-like; anterior portion pointed; caudal portion curved anterodorsally; dorsal margin follows almost straight and with protuberance in between anterior and median third; ventral margin mostly rounded; median third longer than high, setose. Endosoma ( Fig. 3E–H View FIGURE 3 ) enclosing almost all phallobase and aedeagus lengths laterally and ventrally; asymmetrical, with two different sides linked ventrally, of which: one side is longer and with apex curved ventrally, comma-like; and other side is shorter and apically truncated, bearing triangular expansion ventrally directed to the longest side of endosoma at aedeagus midlength ( Fig. 3E, F View FIGURE 3 ). Phallobase membranous, shorter than endosoma; enclosing aedeagus half-length laterally and ventrally; slightly visible in lateral view, apically and dorsally. Aedeagus ( Fig. 3E–H View FIGURE 3 ) opened dorsally; apically, narrowing and with pair of aedeagal hooks ( Fig. 3F–H View FIGURE 3 ), subequal in length, longer and thinner than aedeagus, but curved differently: one aedeagal hook curved anterodorsally and which follow the comma-like and longer apical lobe of endosoma; the other strongly curved laterally, crossing aedeagus ventrally. Suspensorium V-shaped. Anal tube ( Fig. 3I, J View FIGURE 3 ), in dorsal view, as long as wide and with posterior margin rounded; setose.
Female terminalia. Posterior margin of sternite VII ( Fig. 4B View FIGURE 4 ) medially bearing two slightly round projections; setose. Gonoplacs ( Fig. 4C View FIGURE 4 ) sclerotized; subrectangular; setose. Anterior connective lamina of gonapophysis VIII ( Fig. 4D View FIGURE 4 ) with two apical teeth, curved and subequal; with wide rounded and sclerotized flap laterad of teeth. Posterior connective lamina of gonapophysis IX ( Fig. 4E, F View FIGURE 4 ) distal part, in lateral view ( Fig. 4F View FIGURE 4 ), with several straight and thin spines, starting on stem and following almost until apex; spines of distal part are larger than spines on stem; middle portion with several pits ( Fig. 4F View FIGURE 4 ); apex setose ( Fig. 4F View FIGURE 4 ); region in between the distal parts with three plates of setae ( Fig. 4E View FIGURE 4 ). Segment X of anal tube ( Fig. 4G, H View FIGURE 4 ) as long as wide; posterior margin ( Fig. 4G View FIGURE 4 ) pointed; setose.
Taxonomic notes. The new species is similar to Papagona papoosa in coloration, but they can be distinguished by some external morphological characters and male terminalia. This species differs from other species of the genus by the following group of characters: (1) male coloration pattern ( Figs 1 View FIGURE 1 , 2A–C View FIGURE 2 ) is similar to P. papoosa (with slight differences on abdominal sternites coloration), but very different from P. succinea (which is red or reddish-yellow); (2) length and shape of vertex ( Fig. 2B, E, H View FIGURE 2 ), longer and more pointed than other species of the genus; (3) central plate of frons with median carina which is absent in P. papoosa ; (4) sides of frons with three sensory pits aligned diagonally in the middle of triangle of sensory pits ( Fig. 2C, F, I View FIGURE 2 ); (5) posterior margin of pygofer with concavity on ventral half ( Fig. 3A View FIGURE 3 ); (6) protuberance of gonostylus more conspicuous than in other species of genus ( Fig. 3D View FIGURE 3 ); and (7) phallus with pair of aedeagal hooks, one curved anterodorsally and other curved laterally, crossing sides of phallus ( Fig. 3E–H View FIGURE 3 ).
Plant associations. Unfortunately, as type specimens were collected using a vacuum sampler, no specific plant record was taken. However, vacuum samples were taken mostly from dense grasses in a dry lake bed.
Etymology. The specific epithet is an honorific for Dr. Christopher H. Dietrich (INHS), who collected specimens of the type series and many other caliscelids from Central and South America and allowed us to study these curious planthoppers.
