al., Chapter 8 and 9).
23- Philopotamus variegatus (Scopoli, 1763)
MATERIAL STUDIED: 2♂ (V, VI)
Ter Basin: T3, T17
DISTRIBUTION AND ECOLOGY
Central and southern European species. In the Iberian Peninsula it has been recorded in
northern basins.
This species prefers headwaters of pristine rivers, similarly with P. montanus (see Vieira-
Lanero, 2000).
Wormaldia McLachlan, 1865
The difficulty to distinguish larvae, and even adults, from this genus is notable. Therefore, only
the adults found in the sampled areas (in Llobregat basin) are presented here, although larval
specimens from the same genus were found in Tordera, Besòs, Turia and Júcar Basins.
24- Wormaldia triangulifera McLachlan, 1878
MATERIAL STUDIED: 1♂ (IV)

TAXONOMIC REMARKS

DISTRIBUTION AND ECOLOGY

recorded in eastern basins (González et al., 1992).
The species has been recorded in headwater reaches between 300-1200 m of altitude
(Décamps, 1967). The male collected in Llobregat basin was found in a small karstic
stream located in a protected area (Sant Llorenç del Munt Natural Park).
