Trichopteran species list
TAXONOMIC REMARKS
The males collected in Llobregat River correspond to the “Pyrenees form” (H. Malicky,
pers. comm.) but more information is still necessary to consider them as the subspecies
Rh. dorsalis obtusidens (Malicky, 2002).
DISTRIBUTION AND ECOLOGY
Species widely distributed from central to southern Europe. In the Iberian Peninsula it
has been found in central and northern Spanish areas (González et al., 1992).
According to Décamps (1967), Rh. dorsalis is found mostly in rivers at medium or low
altitudes under 500 m. In the Iberian Peninsula it has been recorded in calcareous areas
(García de Jalón, 1982). In the sampled Mediterranean area it is frequent both in
calcareous and siliceous headwaters and middle parts from 220 m to 1200 m. Larvae can
tolerate a wide range of environmental conditions (Moretti & Mearelli, 1981; Bonada et al.,
Chapter 8), although it has been considered as an intolerant species in rivers of central
Spain (González del Tánago & García de Jalón, 1984).

Ter basin: T1, T2, T8, T9, T10, T11
DISTRIBUTION AND ECOLOGY
Central and southwestern European species. In the Iberian Peninsula it has been only
recorded in northwestern basins.
