Among the species of Megalostomis, several morphological differences exist and the head and thorax are highly variable, therefore, the most useful morphological characters are: presence of a carina in the inter-ocular area, development of anterior teeth on the mandibles, clypeus sculpture, and the degree of retraction of the head inside the prothorax. The thorax may have strong constrictions, which are often present in those species showing great development of the head and mouthparts. The elytra are also variable; the most distinctive characters are the coloration pattern and the ordering of the elytral punctation. Although also variable, the abdomen and legs are not especially useful for the recognition of species groups. The pygidium may possess distinct sculpture patterns, which are useful to diagnose among species.","source":"A comprehensive guide to the Argentinian case-bearer beetle fauna (Coleoptera, Chrysomelidae, Camptosomata)","sourceTaxonKey":130845203},{"key":464408006,"taxonKey":1048367,"type":"distribution","language":"eng","description":"Distribution.
