(Figs. 1, 2, 3–10)
Examined material. Holotype 3: “ Brasil, Amazonas, Iranduba. Sítio Santa Maria, 21.xi.2015, coleta manual de casal em cópula em arbusto no período da noite, (Pádua, D.G. leg.) [03°06’S / 60°19’W]” (INPA).
Paratypes: Same data as holotype, but 21.xi.2015 (1♀ INPA); 20.xi.2018 (531♀ INPA; 13 MZUSP; 13 MNRJ).
Etymology. From Latin bi = occurring twice; lineata = marked by a line, referring to the prosternum marked by two parallel lines.
Diagnosis. Transverse ridge of frons medially with elevated protuberance at apex (figs 4A–C, 8A). Clypeum with lateral projection pointing ventrally; lateral fold symmetrical, D-shaped, gradually arching towards apex (figs 4A–B). Pronotum conspicuously rugose, granulated (figs 4E, 7A–C). Prosternum in male with two light brown longitudinal parallel lines (figs 3C, 5A). Epiproct in male with rounded base (fig 5C); in female idem, but medially with light emargination at base (fig 8D). Male subgenital plate approximately 1.3 times longer than sternite 8 (fig 5E); in female with dark brown spots, base gradually widening towards apex; basal and lateral margins straight, apical margin medially with convex projection, having subtriangular spot at projection (fig 9A). Phallic complex with distal half subtriangular in dorsal view (figs 6A–C). Transverse sclerite heavily sclerotized; lateral margin slightly curved; apical margin with subtriangular projection at left side (figs 6A–B). Lophi with basal third elongated; medial third subrectangular; apical third with straight hook, pointing dorsally (figs 6A–B). Copulatory chamber membranous, translucid; duct of spermatheca sinuous, single, without digitiform expansions, widening towards apical diverticula; apical diverticula single, slightly sclerotized, elongated, wider than duct apex (fig 9C).
Description. 3 Body (alive) dark green.
Head. Fastigium in dorsal view dark brown with light brown margins; apex rounded, medially slightly emarginated (fig 3B); in lateral view dark brown with light brown spots; medial longitudinal carina from base to apex; base in lateral view 5.9 times higher than apex (fig 4D). Coronal suture conspicuous (fig 3A). Gena with subquadrangular spot (fig. 4D); with white spot when alive. Transverse ridge of frons medially with elevated apical protuberance (figs 4A–C, 8A). Clypeum with lateral projection pointing ventrally; lateral fold symmetrical, D-shaped, gradually arching towards apex (figs 4A–B). Last maxillary palpomere 2.4 times longer than wide, with conspicuous mesial emargination (fig 4B).
Thorax. With white spots (alive). Pronotum conspicuously rugose, granulated (figs 4E, 7A–C). Meso- and metanotum dark brown with light brown spots (figs 3A). Prosternum with two light brown longitudinal parallel lines (figs 3C, 5A). Meso and metabasisternum rugose with scattered granules (fig 5B).
Legs. All legs from base to apex gradually shifting from light green to dark green (fig. 10A).
Abdomen. Epiproct in male with rounded base (fig 5C). Cercus robust, cylindrical, with slight apical folding (fig 5D). Subgenital plate approximately 1.3 times longer than sternite 8 (fig 5E).
Genitalia. Distal half subtriangular in dorsal view (figs 6A–C). Transverse sclerite heavily sclerotized; lateral margin slightly curved; apical margin with subtriangular projection at left side (figs 6A–B). Lophi with basal third elongated; medial third subrectangular; apical third with hook straight, pointing dorsally (figs 6A–B). Ectophallic valves in dorsal view with basal margin conspicuously thin, abruptly widening towards apex; lateral margin conspicuously sinuous; apical margin wide, rounded (figs 6A–C)
Description. ♀ As described for genus above.
