DISTRIBUTION AND ECOLOGY European species. In the Iberian Peninsula it is present in northern basins. Trichopteran species list This species has been found in permanent headwater reaches (Sommerhäuser et al., 1997) without presenting a summer diapauses (Malicky, 1987). P. cingulatus has been found coexisting with P. latipennis but reaching higher altitudes (Vieira-Lanero, 2000). In sampled area it is an intolerant species, especially to conductivity, suspended solids and phosphates (Bonada et al., Chapter 8). 71- Potamophylax latipennis (Curtis, 1834) MATERIAL STUDIED: 257L, 8P♂ 12P♀ (VIII), 10♂3♀ (II, VII, VIII, X) Ter Basin: T7, T9, T10, T12, TM1, TM3, TM4, TM5 Tordera Basin: ToM7, ToM8 Besòs Basin: B8a, B29, B35, B36 Llobregat Basin: L54, L56, L60a Adra Basin: AD5 Guadalfeo Basin: GU1, GU11, GU15 DISTRIBUTION AND ECOLOGY This species is distributed around Europe, Siberia and Anatolia. In the Iberian Peninsula it is distributed in northern basins, although it has been recorded in some southern areas (see González et al., 1992). Similarly to P. cingulatus, this species is present in mountain headwater reaches. P. latipennis is more intolerant to environmental quality variables than the former species, especially to ammonium concentration. Halesus Stephens, 1836 72- Halesus digitatus (Schrank, 1781) MATERIAL STUDIED: 51L, 2♂ (VII, X) Ter Basin: T8, T10, T12 Besòs Basin: B35 Llobregat Basin: L44, L54, L68 Noguera Ribagorçana Basin: OUT200m DISTRIBUTION AND ECOLOGY This species is distributed around Europe reaching Iran. In the Iberian Peninsula only has been recorded in northeastern basins, as has been in our case. In other European areas with karstic formations, H. digitatus has been found a dominant species in both temporary (Kiss, 1984) and permanent streams (Sommerhäuser et al., 1997). In our sampled streams, specimens were found in calcareous/siliceous headwaters located in a wide altitudinal range. 73- Halesus radiatus (Curtis, 1834) MATERIAL STUDIED: 103L Ter Basin: T7, TM1, TM4, TM5 239
Chapter 6 Tordera Basin: ToM6, ToM7, ToM8, ToM10, ToM11, ToM12, ToM15 Besòs Basin: B7a, B8a, B32, B35, B36 Llobregat Basin: L44, L56, L68 Mijares Basin: MI7 Turia Basin: TU1, TU2, TU4 Júcar Basin: JU1, JU7, JU8 DISTRIBUTION AND ECOLOGY European species. In the Iberian Peninsula it is distributed in central and northern basins, as in our samples. This species has a wide ecological range beeing able to survive in headwater and middle reaches (Vieira-Lanero, 2000) with a permanent flow (Sommerhäuser et al., 1997). In our samples it has been found in headwaters at high to medium altitude. In these conditions, larvae appear sensitive to phosphates, suspended solids and conductivity but may be present in low ammonium concentrations (Bonada et al., Chapter 8). 74- Halesus tessellatus (Curtis, 1834) MATERIAL STUDIED: 142L Besòs Basin: B35 Turia Basin: TU1, TU2 Júcar Basin: JU7, JU8 Segura Basin: SE1, SE3, SE4 Adra Basin: AD5 Guadalfeo Basin: GU1, GU5, GU11, GU12, GU15 TAXONOMIC REMARKS Although we did not find pupae or adults from H. tessellatus in the sampled basins, Zamora-Muñoz & Alba-Tercedor (1995) indicated the presence of this species in the Iberian Peninsula. The larvae examined correspond to this species according to Panzeböck & Waringer (1997), even assuming difficulties found to differentiate H. tessellatus from H. digitatus. Pupae and adult material should be analyzed to confirm the presence of H. tessellatus in northern basins, where we only found larval specimens. DISTRIBUTION AND ECOLOGY European species with some records in Siberia (Lepneva, 1971). In the Iberian Peninsula it has been recorded until now only in southern areas. In our sampled basins, H. tessellatus has been collected in mountain pristine headwaters with a low conductivity (Zamora-Muñoz & Alba-Tercedor, 1995), but it has been collected in high saline water in central Europe (Botosaneanu & Malicky, 1978). In the Mediterranean sampled basins it appears to be more sensitive to ammonium, phosphates, suspended solids and conductivity than H. radiatus (Bonada et al., Chapter 8). Stenophylax Kolenati, 1848 Many difficulties are found to identify Stenophylax species in the Iberian Peninsula, because not all the recorded species have described larvae. Therefore, we only include here few pupae or adults collected in the studied area. However, larvae of this genus have been found in several temporary streams in Besòs, Júcar, Segura, Almanzora and Guadalfeo basins. 240
