Diagnosis. Erect bristles dense and long along the scape, slightly denser and longer on apical half, the apical bristles as long as or longer than scape diameter, the longest ca. 1.2–1.6x scape diameter; near the apical margin of scape generally some bristles recurved upward ( Fig. 6 ); bristles on pedicel and fl.1, approximately of uniform length, ca. 1.2– 2 x fl.3 diameter, on following flagellomeres, short, 0.3–0.5x fl.3 diameter.

Holotype, worker (Tab. I).

Dimensions. Total length, 3.40 mm; forewing length, from apex of costal sclerite to wing tip, 3.64 mm (including tegula, 4.01 mm); maximum head width, 1.65 mm; abdomen width (TIII), 1.32 mm.

Integument color. Black, light brownish on antennal scape, pedicel, mandible, labrum, all trochanters and tarsomeres, basitarsi II, III; last flagellomere and lower quarter of gena yellowish. On face, brownish clypeus, except for black stripes on apical margin and median line; lower parocular areas, broadened below and gradually narrowed to little below the tangent of interorbital maximum. The remaining color characteristics as described for the genus.

Vestiture. Scape with bristles as long as scape diameter, those on apical half slightly longer, ca. 1.2x scape diameter; apex of scape with some recurved bristles; on pedicel and fl.1 some longer bristles, 1.5x fl.3 diameter, on fl.2 and fl.3 little shorter than fl.3 diameter ( Fig. 6 ), and on remaining flagellomeres, ca. 0.5x fl.3 diameter. Other characteristics of the pilosity as described for the genus.

Integument sculpture. As described for the genus.

Form and proportions (measurements in Table I). General shape of the body as described for the genus. Head 1.2x wider than long. Eyes 2.3x longer than wide, slightly convergent below. Malar area 1.8x longer than fl.3 diameter. Clypeus 0.6x shorter than its maximum width, and 0.3x clypeocellar distance. Mandible length 0.5x clypeocellar distance; shape of mandible and labrum as described for the genus. Scape length 1.3x alveolocellar distance, slightly flattened in the middle. Interocellar distance 1.2x longer than ocellorbital distance and 1.9x median ocellus diameter. Scutellum 0.5x shorter than wide. Tibia III 1.1x longer than head width and 4.1x longer than wide. Basitarsus III 2.0x longer than wide and 0.8x narrower than tibia. Forewing 2.8x longer than wide and 2.2x longer than head width; wing venation as described for the genus.

Type material. Holotype, worker, from “Manaus – Boulevard / AM – Brasil – 1239 / ninho 1 – 14-IV-1986 / M.V.B. Garcia”, deposited in RPSP. Paratypes, 20 workers from the same nest of the holotype, with identical labels, all in RPSP except for 2 paratypes in INPA.

Etymology. “ Manauara ” is the common denomination to the people born in Manaus, Amazonas, Brazil, the type locality of the species here described.

Geographical distribution. Apparently it is an endemic species from the north of Amazon basin (biogeographical component NAm, see Camargo & Pedro 2003).

Nest. One nest from Manaus (type material), according to the information on label by M. V. B. Garcia. Details unknown.

Remarks. The pattern of antennal pilosity is similar to C. longicornis , but bristles on apical half of scape longer, generally having some recurved bristles on apex of scape (in C. longicornis they are very short, practically straight; see Remarks on C. longicornis ). Also, most specimens (except the ones from Amapá and Cachoeira da Porteira) are darker mainly on the frons and vertex near the apex of ocular orbits.
