The Last Instar Larvae and Pupae of Mongolian Limnophilinae Crane Flies from Genera Eloeophila, Limnophila and Phylidorea (Diptera, Limoniidae)

Description, illustrations and habitat characteristics are given for the previously unknown larvae and pupae of Eloeophila persalsa (Alexander, 1940), Limnophila (Limnophila) chinggsiskhaniPodenas and Gelhaus, 2001 and Phylidorea (Macrolabina) temelskinPodenas and Gelhaus, 2001 based on specimens from Mongolia. Sclerotisation of the spiracular field, arrangement of the sensory structures on the labrum, length of the antennal segments, and number and shape of the mandible teeth are the main characters found to distinguish the larvae of these genera. The larvae were found in the riparian zone, usually in silt, sand or gravel. Pupae and pupal exuviae of these genera were found in mosses growing on the riverbanks. The female pupal stage is described for the first time for the genus Phylidorea. Eloephila persalsa is recorded from Mongolia for the first time.
