Differential diagnosis.

Cautires singularithorax resemble Cautires apicalis in the body size and color pattern (Figs 2, 5). These species differ in the extent of the bright part of the elytra, which is much smaller in Cautires singularithorax and in V-shaped border between bright and dark part in Cautires singularithorax and almost transverse border in Cautires apicalis . Female genitalia of both species differ in the relative length of valvifers, those of Cautires singularithorax are stout and about 1.8 times longer than coxites (Figs 17, 18). Cautires singularithorax has not been found in the available recently collected material and only unique female specimen is known and we do not have any information on male characters.

Redescription.

Female. Body medium-sized, dorso-ventrally flattened, slender; head, body, posterior half of elytra and appendages dark-brown to black; pronotum and basal half of elytra orange, pronotum and elytra covered with dense orange pubescence. Head small, partly hidden in pronotum, clypeus slightly concave, labrum simply rounded, mandibles slender, strongly curved apically, maxillary with apical palpomere pointed; labial palpi similar in shape. Eyes small, hemispherically prominent, their frontal interocular distance 1.52 times eye diameter. Antennae acutely serrate, covered with short, dark colored setae. Pronotum flat, transverse, 1.45 times wider at base than length at midline; frontal margin concave; lateral margins slightly elevated, posterior angles very acutely projected, pronotum with median areola, areola widest anteriorly and attached to middle of basal margin, connected to anterior margin by keel occupying one third of midline. Elytra flat, with well developed four primary longitudinal costae; secondary costae considerably weaker, often interrupted, cells irregular, often inconspicuous, mostly quadrate. Legs laterally flattened, covered with dark colored setae. Ovipositor with valvifers 1.75 times length of coxites (Fig. 25). Male unknown.
