description: Kaysara Carnimeo, gen. nov.
Type species: Kaysara flavovariegata (Smith, 1879)
Male description. Head: Antennal sockets under supra-antennal projections, with well-developed subtriangularly margined supra-antennal plate on the medial apex; clypeus apical margin with central notch with depth of about 1/ 4, shallower on K. levicrenata, with about 1/6 of clypeus length, forming two acute teeth towards down. Basal region of the clypeus convex, depressed on the basolateral margins. Laterals of the apical margins concave. Mandible bidentate, the apical tooth long and acute, the subapical short, trapezoidal, with the outer margin longer than the inner margin. Basal region of the mandible triangular shaped. Maxillary palpi IV and V about 1.5x longer than III, that is broader than the others; antennae filiform, with 11 flagelomeres, the apical ones slightly arcuate.
Mesosoma: Pronotum constricted in the middle, forming elevations anterior and posteriorly in lateral view. Anterior margin carinated and narrower than the posterior; forewing with nervure 2m-cu received by beyond about 1/4 of the base of the submarginal cell; mesoscutum subquadrate in dorsal view, with dorsal surface slightly convex. A pair of longitudinal submedial sutures and a pair of longitudinal carina laterally, culminating in a transverse posterior carina; scutellum dorsally slightly raised with subtriangular surface. Delimited anteriorly by a deep transverse suture and the posterior margin rounded. Latero-posterior margins with borders enlarged towards the axilla; metanotum short with two sublateral fossae; mesopleural transverse sulcus well-marked, wide or thin; Metapleuron triangular in lateral view; propodeum with convex dorsal surface. Apex of the propodeum with two longitudinal petiolar grooves reaching less than half its extension. Propodeal surface almost smooth; mesepisternal lamellae triangular, narrow and acute, with the apex slightly rounded; a pair of longitudinal sutures on the ventral surface of the mesepistenum; forecoxae with ventral surface slightly convex, the inner margin straighter and the outer more sinuous curved. Hindcoxae with longitudinal carina on the dorsal surface; posterior margins of the mid and hindtibiae with row of projections or serrations, more conspicuous on hindtibiae. With short carina on the external base of the tibia. Hindfemoral-hindtibial joint lobes asymmetrical with inner lobe longest and thickened posteriorly;
Metasoma: Metasoma with constrictions between the segments, mainly in lateral view; First metasomal tergite with length longer than its apical breadth. With a longitudinal sulcus reaching more than half the segment extension. Spiracles slightly raised. Dorsal surface of the tergite I with a rectangular longitudinal slight depression; apical margins of tergites I–VI with transverse smooth fasciae, preceded by a transverse row of setae horizontally arranged; epipygium oval, tapering towards the apex and feebly constricted before the apical margin; first metasomal sternite with tuft of hairs emerging medially on the ventral surface. A medial elevation might or might not occur on the point where the tuft emerges; hypopygium subquadrate, with apical margin enlarged in different ways: lateral rounded enlargement, acute and subapical enlargement or with subquadrate margin;
Coloration. Body predominantly black or much variegated with yellow markings.
Female: Unknown.
Etymology. Ka'aysara is a Tupi word used to refer to the traditional people that inhabit the South and Southeastern coast of Brazil, the same regions where the species of this genus are recorded.
Included species: Kaysara flavovariegata, K. laterolata, K. apiciconcava, K. marginoplicata and K. levicrenata.
Distribution. Brazilian Atlantic Rainforest: Found in the states of Espírito Santo, Paraná, Rio de Janeiro, Santa Catarina and São Paulo. All locality data provided for the new species correspond to new records for the genus.
Discussion. The tuft of hairs was absent in some of the specimens studied. This could happen often because the tuft can easily be damaged during specimen preparation.
