Western Palaearctic trichopterological miscellanea (Insecta: Trichoptera)

Abstract

Original information (on morphology, variability, or distribution) is provided for several Caddisfly species from continental France, Corsica, Tunisia, Italy, etc., including - for instance - the rediscovery, after more than a century, of Sericostoma mesopotamicum McL. (Anatolia). Wormaldia occipitalis vaillantorum Bots. (R6dhos) is transferred to the Bulgarian species W, juliani Kumanski. Interesting teratological cases are illustrated in the geneta Polycentropus and Hydropsyche. For Allogamus stadleri Schmid the status of bona species - often denied - is firmly confirmed. The unknown females of A. stadleri and of Thremma sardoum Costa are for the first time illustrated, on specimens from CBte d'Or, and, respectively, from Corsica. Three new synonymies are proposed in the genera Hydropsyche and Limnephilus. Hydropsyche contubernalis turkomanica n. ssp. (Turkmenistan) and Limnephilus cianjicconiae hispaniae n. ssp. (Spain: Huesca and Teruel) are described - this last case being remarkable, the species having been only known from Sicily and peninsular Italy
