Oxythyrea

Larva: Cranium elongate with dorsal margin more or less convex at its entire length (length of dorsal straight portion of cranial margin less than one third of maximum width of cranium). Tegilla fused and densely setose (average distance between two setae about twice length of palus), campus absent. Dorsal parts of last abdominal segment densely setose, covered with equal short setae, without ring of prominent long setae or bald circular field. Epipharynx: Zygum with 14–15 stout conical setae and 13–14 similarly shaped setae at its proximal base. Transverse proximal row of setae and sensilla on ligula composed of 6–8 stout lanceolate setae and 0–4 campaniform sensilla. Tegillar setae about size of pali or twice as long, only few longer setae present. Chaetoparia with 60–90 and 61–68 setae on right and left side respectively. Stridulatory area of mandibles with 9–13 transverse ridges, ridges in the apical third about ½ of the width of proximal ridges.
