Capellari (2♂, IFTM)  Recognition (male).This species can be distinguished based on the following combination of characters: postpedicel about 3.5X as long as wide, elongate subtriangular, gradually tapering to apex, outer surface with 5–6 short stubby projections, with dorsal margin infuscate ( Figs 3, 6, 7); face relatively broad ( Fig. 3); fore femur pale yellow, not laterally compressed, without dense setulae along anteroventral margin ( Fig. 12); apicoventral epandrial lobe projecting ventrally with narrow pointed apex ( Fig. 22); hypandrium nearly symmetrical ( Fig. 21); cercus pale, not extensively infuscate on ventral (inner) surface ( Fig. 20). This species is morphologically very similar to  C. carolinaLimeira-de-Oliveira & Brooks sp. nov.and  C. pennaticornis, but can be distinguished by the postpedicel with short stubby projections and by the pale yellow fore femur that lacks dense setulae anteroventrally.   Description (male).Body length: 5.6̄ 6.8 mm, wing length: 4.2–4.9 mm. Head:Eyes uniformly dull red. Upper-most 6–7 postocular setae black, lower 11–13 white, lower-most seta dark brown. Frons subrectangular (wider than high), dark metallic blue-green with violet reflections, silvery white pruinosity on lateral margins. Face ( Fig. 3) opaque yellow-brown with silvery white pruinosity on upper and lateral parts, relatively broad. Clypeus subrectangular (wider than high), concolorous with face, more than 1/4 face height. Palpus yellowish brown, ovoid with short black setulae on apical half of outer surface. Proboscis mainly yellowish, anterior surface of each labellar lobe dark brown with close-set row of 2 elongate thickened black setae with apical third abruptly downturned or curled, each labellar lobe with long thin brown seta preapically and near middle. Antenna ( Figs 3, 6, 7) with scape and pedicel pale yellow below and infuscate yellowish brown dorsally, postpedicel pale basally with dark apicodorsal margin and apex, inner surface with distinct whitish pruinosity; scape obconical, with acute ventral process; pedicel short; postpedicel about 3.5X as long as wide, elongate subtriangular, gradually tapering to apex, outer surface with 5–6 short stubby projections (occasionally bifurcated), arista-like stylus dorsal, well before middle of dorsal margin of postpedicel, basal article elongate nearly extending to tip of postpedicel, distal article with long pubescence. Thorax:Scutum metallic blue-green with violet reflections, bronze area above notopleuron (postsutural). Scutellum metallic blue-green with violet reflections. Mesopleuron gray pruinose with dark bluegreen background coloration, with metallic reflections. Legs:Mainly pale yellow with black setae, except as noted below. Fore leg: Femur not laterally compressed, without dense setulae along anteroventral margin ( Fig. 12); tibia not swollen; tarsomeres 3–5 with sparse velvety pile on ventral surface, claws slightly enlarged (relative to other legs). Mid leg: Coxa with lateral surface brown with silvery pruinosity, mainly pale apically; tarsus infuscate from tarsomere 2 onwards. Hind leg: Tarsus infuscate from tarsomere 2 onwards. Wing:With slight brownish tint; M with weak arc beyond bend. Abdomen:Tergites 1–5 dark metallic green, with silvery pruinosity laterally. Hypopygium( Figs 20–22): Epandrium dark brown, with apicoventral 1/3 pale; left basiventral epandrial lobe short and rounded with basiventral epandrial seta on ventral medial surface, right basiventral lobe forming dentiform projection immediately distal to basiventral epandrial seta; apicoventral epandrial lobe projecting ventrally with narrow pointed apex, bearing 2 long lateral setae, medial surface of lobe forming weakly sclerotized rounded process (left and right apicoventral epandrial lobes largely symmetrical). Surstylus: dorsal arm with broad medioventral lobe, with long finger-like dorsal process bearing long apical seta, apex broadly expanded with microtrichia ventrally; ventral arm with sinuous apical seta, apex rounded, with subapical process present. Postgonite digitiform, slightly curved ventrally. Cercus subovoid, pale with dark outer margin, with sparse short pale setae dorsally and short erect pale setae along margin, with one longer pale seta apically. Hypandrium ( Fig. 21) rounded apically, with small subapical dentiform process on each side, desclerotized medially. Sperm pump folded back on itself, with simple single fold, opposing surfaces tightly appressed. Phallus strongly widened preapically, with preapical flap-like dorsal process bearing lateral tooth on each side, apex narrow. Ejaculatory apodeme long with weak ventral curve. Female:Unknown.   Distribution.This species is widely distributed in northeastern Braziland occurs in the gallery forests of the Cerrado and the Amazonian forest biomes of Chapada das Mesas National Park ( Maranhão) ( Fig. 28) and Sete Cidades National Park ( Piauí), as well as in relict habitats of the Atlantic Forest in Serra das Confusões National Park ( Piauí) ( Fig. 29) and Ubajara National Park ( Ceará) ( Fig. 30). This species has also been collected from the southern Brazilian locality of Getulina, São Paulo.   Etymology.The specific epithet is based on the Portugese word for northeastern, in reference to the northeastern distribution of this species within South America.   Remarks.This species appears closely related to both  C. pennaticornisand  C. carolinaLimeira-de-Oliveira & Brooks sp. nov., based primarily on a similar male postpedicel that is elongate subtriangular in shape and bears numerous projections along the outer surface. 1880439627 2014-09-30 CZMA, PARNA Parque Nacional Chapada das Mesas & Chapada das Mesas & de Malaise & J.
