| Title | Description of the larva of Protanypus sp. A from the Italian Alps |
| Abstract | We describe e the larva of Protanypus sp. A from the Italian Alps. All the larval characteristics fit the diagnosis of the genus, but it is impossible to assign the specimens examined to one of the known species. The low number of labral scales (12-14) and the serrated median lamellae of the medioventral appendix of the prementum exclude the identity of the species with P. morio or with the East Palaearctic P. pseudomorio. The antennal ratio (2.3) excludes the identity with P. caudatusor P. forcipatus, which are the other two Protanypus species known from the Alpine region. In Sæther's key (1975) the larva fits with the Nearctic P. ramosus, but identification of the species needs to be supported by pupal and adult material. In the Southern Alps, the genus is restricted to cold lakes at high altitude and is confirmed as an indicator of oligotrophic lakes. |
