Silva( 1♂, CNC); same data except, Armadilha Suspensa Lâminad׳água, 20̄  30.ix.2013( 1♂, CZMA).  Recognition (male).This species can be distinguished based on the following combination of characters: postpedicel about 4.5X as long as wide, elongate subtriangular, gradually tapering to apex, outer surface with 6–7 long projections, pale with projections and dorsal margin infuscate ( Figs 2, 4, 5); face relatively narrow ( Fig. 2); fore femur somewhat laterally compressed with anterior surface bright yellow-orange, with infuscate and silvery pruinose area anteroventrally at mid length, with associated crest of dense elongated setulae below infuscate area ( Fig. 11); apicoventral epandrial lobe short and subtriangular ( Fig. 17); hypandrium asymmetrical ( Fig. 16); cercus extensively infuscate on ventral (inner) surface ( Fig. 15).   Description (male).Body length: 6.1 mm, wing length: 4.2 mm. Head:Eyes uniformly dull red. Upper-most 5–7 postocular setae black, lower 10–11 white, lower-most 2–3 dark brown. Frons subrectangular (wider than high), dark metallic blue-green with violet reflections, silvery white pruinosity on lateral margins. Face ( Fig. 2) opaque yellow-brown with weak silvery white pruinosity on upper part, relatively narrow, narrowest just below middle. Clypeus subrectangular (slightly wider than high), concolorous with face, about 1/4 face height. Palpus 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, each labellar lobe with long thin brown seta preapically and near middle. Antenna ( Figs 4, 5) with scape and pedicel pale yellow below and infuscate 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 4.5X as long as wide, elongate subtriangular, gradually tapering to apex, outer surface with 6–7 long projections (occasionally bifurcated), arista-like stylus dorsal, well before middle of dorsal margin of postpedicel, basal article elongate but not extending to tip of postpedicel, distal article with long pubescence. Thorax:Scutum predominantly metallic green with violet and blue reflections, anterior half with strong bronze reflections, dark bronze patch above notopleuron immediately posterior to suture. Scutellum concolorous with scutum. Mesopleuron gray pruinose with dark brown background coloration and weak metallic green and bluish reflections. Legs:Mainly pale yellow with black setae, except as noted below. Fore leg: Coxa with anterior surface mainly dark brown with prominent silvery pruinosity, lateral surface mainly pale with infuscate and silvery pruinose area at base; femur somewhat laterally compressed with anterior surface bright yellow-orange, with infuscate and silvery pruinose area anteroventrally at mid length, with associated crest of dense elongated setulae below infuscate area ( Fig. 11); tibia not swollen; tarsomeres 3–5 with sparse velvety pile on ventral surface, claws enlarged (relative to other legs). Mid leg: Coxa mainly dark brown with silvery pruinosity, pale apically; femur brown on anterior and posterior surfaces; tarsus infuscate from tip of tarsomere 2 onwards. Hind leg: Coxa with lateral surface dark brown with silvery pruinosity; tarsus infuscate from middle of tarsomere 2 onwards. Wing:Weakly tinted brown, M with weak arc beyond bend (similar to Brooks et al.2010, fig. 2E). Abdomen:Tergites 1–5 brownish black with weak metallic greenish reflections and silvery pruinosity laterally, tergite 5 pale posteroventrally with weaker pruinosity. Hypopygium( Figs 15–17): Epandrium dark brown, with apicoventral portion pale, basiventral epandrial seta present on each side at apical 2/3, right and left basiventral epandrial lobe not developed; apicoventral epandrial lobe relatively short, subtriangular, with dark narrow apex, bearing 2 long pale lateral setae. Surstylus: dorsal arm with sac-like medioventral lobe, with short finger-like dorsal process bearing tiny apical seta, apex slightly expanded with small patch of microtrichia medially; ventral arm with sinuous apical seta, apex rounded, with subapical process present. Postgonite digitiform. Cercus subovoid, pale on dorsal (outer) surface ( Fig. 17), extensively infuscate on ventral (inner) surface ( Fig. 15), with sparse short pale setae dorsally, ventrally and marginally, and one long pale seta apically. Hypandrium ( Figs 16, 17) asymmetrical, left side with apical projection bearing well-developed subapical dentiform process, right side with weak subapical process, desclerotized medially. Sperm pump folded back on itself, with simple single fold, opposing surfaces tightly appressed. Phallus with narrow lateral preapical process. Ejaculatory apodeme with ventral curve. Female:Unknown.   Distribution.This species is known only from the Brazilian state of Maranhão, where the typeseries was collected in a gallery forest ( Fig. 28) within the Cerrado biome of Chapada das Mesas National Park, along with part of the typeseries of  C. nordestinaLimeira-de-Oliveira & Cumming sp. nov.and specimens of  C. brevitarsisBrooks.   Etymology.The specific epithet refers to the Maranhãomunicipality of Carolina, where the typeseries was collected.   Remarks.This species appears to be closely related to  C. pennaticornis, with which it shares similar antennal morphology, as well as several additional putative synapomorphies (see “Remarks” under  C. pennaticornis). 1880439699 2013-06-14 CZMA, PARNA Parque Nacional Chapada das Mesas & Chapada das Mesas & Varredura & J.
