ABSTRACT

The collection of adults, mature male pupae, and the absence of confusing species at the sampling sites located in the Cevennes and French Alps enabled descriptions of the hitherto unknown larvae of Plectrocnemia cevennensis Coppa 2011 and P. praestans McLachlan 1884 (Trichoptera, Polycentropodidae). We present information on the morphology of the larvae and illustrate the most important diagnostic features. In the context of the larval key to European Plectrocnemia species by Waringer Graf (2020), P. cevennensis keys together with P. scruposa McLachlan 1880, whereas P. praestans keys with P. conspersa (Curtis 1834). These two species pairs are morphologically very close; P. cevennensis and P. scruposa can be separated by the numbers of secondary setae on the last abdominal sternum, but the separation of P. praestans and P. conspersa is not always possible.

ABSTRACT

The present paper describes the previously unknown larva of Sericostoma galeatum based on French material. Information on the morphology of the larva is given, and the most important morphological characters are illustrated. Sericostoma galeatum is very close to the S. personatum / S. flavicorne species pair and cannot be separated yet from those confusing congeners. With respect to the distribution, S. galeatum is confined to the French, Italian, and Swiss western Alps and the Apennines. In addition, ecological information is provided.

ABSTRACT

Cyrnus cintranus is one of five Cyrnus species with distribution ranges restricted to western Europe. In this paper, we redescribe the poorly defined female of C. cintranus. We also draw attention to the existence of a previously unmentioned morphological feature that aids significantly in the identification of the female of C. cintranus, separating it from the females of the other Cyrnus species. New data are provided on the distribution and ecology of this species.

ABSTRACT

The morphology of the larvae of three French species of Psychomyiinae: Psychomyia pusilla, Metalype fragilis and Paduniella vandeli are described. A set of characters on the head, the prothorax, and the anal prolegs makes it possible to identify the larvae of the fourth and fifth instars. A brief study of the world distribution of the genera Psychomyia, Metalype, and Paduniella is presented. An examination of the larvae of these three genera from literature data and personal observations offered us the possibility to test the validity of the set of characters obtained for the three French species. A key (with comments) of the three genera is provided.
