Lannapsyche Malicky

Lannapsyche Malicky, 1989: 11 .

Type species: Lannapsyche chantaramongkolae Malicky, 1989 , original designation by monotypy.

Type locality: Thailand .

The species in this genus are characterized by having almost completely reduced preanal appendages (superior appendages), and a pair of sclerotized hairy pads located near the caudal margin of tergite IX. Segment X sometimes with other lobes and processes, like intermediate appendages that are not homolog with the primary segmental appendages. The preanal appendages form concave or convex setal surfaces. The mesal nodule on the first segment of the maxillary palps is present in all examined species of the genus. This nodule was not recognized and not described in the original genus diagnosis but was considered representing one of the main diagnostic characters for the Philorheithridae by Mosely (1936). The cephalic groove pattern, as well as the cephalic and thoracic setose wart pattern, appear almost identical at all examined species. The genus thus contrasts the genus Phraepsyche characterized by including species with completely different groove and wart pattern.

Lannapsyche species rarely come to light, but can be collected at daytime along small brooks or springfed streams.
