Trichopteran species list<br />

calcareous/siliceous headwaters mountain streams with a well-developed riparian forest.<br />

González del Tánago & García de Jalón (1984) suggest that H. siltalai can tolerate some<br />

pollution what would agree with our results as this species appear to be slightly tolerant<br />

to suspended solids, phosphates and ammonium concentrations, but it is very sensitive<br />

to conductivity (Bonada et al., <strong>Chapter</strong> 8).<br />

39- Hydropsyche tibialis McLachlan, 1884<br />

MATERIAL STUDIED: 7L<br />

Guadalfeo Basin: GU1 GU11<br />

DISTRIBUTION AND ECOLOGY<br />

Endemic species from the Iberian Peninsula where it has found in western and southern<br />

areas.<br />

This species has been recorded previously in mountain headwaters and clean reaches<br />

(Vieira-Lanero, 2000). In the Guadalfeo basins it has been found over 1500 m.<br />

Cheumatopsyche Wallengren, 1891<br />

40- Cheumatopsyche lepida (Pictet, 1834)<br />

MATERIAL STUDIED: 2L, 1P♂ (X)<br />

Llobregat Basin: L42<br />

Júcar Basin: JU2, JU3, JU4, JU12, JU13<br />

Segura Basin: SE5<br />

DISTRIBUTION AND ECOLOGY<br />

Species distributed around Europe and southwestern Asia. In the Iberian Peninsula us<br />

widely distributed, although in the sampled Mediterranean basins lacks in the most<br />

southern basins, probably because an appropriate habitat was unavailable.<br />

C. lepida has been associated to middle and lowland reaches beeing present in clean<br />

waters although it can be also tolerant to some pollution (Vieira-Lanero, 2000). In<br />

Llobregat, Júcar and Segura rivers C. lepida was found in midstream reaches with a fair<br />

water quality where it is able to tolerate a wide range of phosphates concentration<br />

although it is quite sensitive to suspended solids, conductivity and ammonium.<br />
