Metalype Klapálek, 1898
44- Metalype fragilis (Pictet, 1834) (Psychomyia fragilis)
MATERIAL STUDIED: 8L
Segura Basin: SE1
Trichopteran species list
DISTRIBUTION AND ECOLOGY
West European species. In the Iberian Peninsula has been recorded in northern and
southern basins.
In the sampled Mediterranean area, M. fragilis is associated to calcareous midstream
reaches at high altitude, in concordance to Edington & Alderson (1973).
Tinodes Curtis, 1834
Three species with undescribed larvae are recorded from south Spain (T. algiricus McLachlan,
1880, T. maroccanus Mosely, 1938 and T. baenai, González & Otero, 1984). This makes difficult
the identifications of larvae from the Mediterranean Spanish Rivers, especially from southern
basins. Identifications of specimens presented here were obtained from already know larvae and
they should be taken with caution.
45- Tinodes assimilis McLachlan, 1865
MATERIAL STUDIED: 13L, 1♂ (VII)
Llobregat Basin: L56
Segura Basin: SE1
Almanzora Basin: AL6, AL7, AL11, AL14
Aguas Basin: AG2
Guadalfeo Basin: GU1
DISTRIBUTION AND ECOLOGY
West European species. In the Iberian Peninsula is widely distributed.
Larvae of the hygropetric T. assimilis has found in headwaters (Vieira-Lanero, 2000)
reaching the 1800 m of altitude in some of our sampled sites.
46- Tinodes dives (Pictet, 1834)
MATERIAL STUDIED: 11L
Llobregat Basin: L44, L45, L56
Júcar Basin: JU6
DISTRIBUTION AND ECOLOGY
Central and southern European species. In the Iberia Peninsula it has been found in
northeast basins. In the sampled Mediterranean area it also appears in more central
basins.
This species has been found in mountain rivers at intermediate altitudes (Décamps,
1967). In the sampled basins, larvae we collected in calcareous headwater reaches with a
good biological and riparian quality.
