General color light reddish brown. Head dark posteriorly, becoming paler in a broad transverse band forward of median ocellus; clypeus dark brown, M-line distinct in transverse pale band. Ocelli black; eyes black with a white band in the base. Antennae with a uniform yellowish-brown pattern. Pronotum brown with clear spots forming a characteristic pattern and with a pale median band; rugosities indistinct. Maxillary lacinia yellowish-brown, with the teeth sharp-pointed and red-brown. Mandible yellowish, with five sharp-pointed dark brown teeth. Glossae, paraglossae and labial palps pale yellow. Legs with a fringe of fine setae along the outer margin from trocanter to tarsi. Abdomen dark brown in the mature nymphs; apex of the abdominal segments with a fringe of bristles. Cerci dark brown at the base and paler to the apex. <b>Measurements</b>. Larval Head: 2.9 x 2.2mm; Pronotum: 3.38 x 1.79mm; Abdomen: 4.3mm; total length: 10.59mm (n = 379). <b>Remarks.</b> Larvae of <i>K. gracilenta</i> are distinguished from known members of the genus on the basis of the pale transverse band which extends between the compound eyes, covering part of the ocellar triangle and obscuring the M-line (Fig. 1). The marginal lacinial bristles include a few (ca. 3-4) longer ones at the base of the second tooth and a row of shorter ones extending to the lacinial base (Fig. 2). The latter character distinguishes larvae of this species from those of <i>K. tijucana</i> Dorvillé &amp; Froehlich (Dorvillé &amp; Froehlich 2001) and <i>K. reticulata</i> (see Fig. 8), whereas the smaller size and shape of the epicranial suture distinguishes <i>K. gracilenta</i> larvae from those of the much larger larvae of <i>K. neotropica</i> (Jacobson &amp; Bianchi) (Bispo &amp; Froehlich 2008). <b>Distribution</b>. Brazil: São Paulo; Rio de Janeiro; Minas Gerais; Espírito Santo.
