Description of a Larva of Kargalarva permosialis gen. et sp. nov. (Coleoptera: Schizophoromorpha) from the Kargala Fossil Site

An aquatic larva of the holometabolan species Kargalarva permosialis gen. et sp. nov. is described from the Upper Permian of the Kargala outcrop (Orenburg Oblast, Russia). This larva was formerly known as Permosialis sp. from the preliminary description by A.G. Sharov (1953). It is assigned to the infraorder Schizophoromorpha (Coleoptera). An aquatic lifestyle is assumed for at least a part of the taxa of this infraorder. The larval characters, shared by the orders Coleoptera and Megaloptera, are discussed.
