This species can be found in different river reaches, preferring headwaters (see Vieira-
Lanero, 2000). Accordingly, our larvae were found in headwaters and midstream reaches
with different biological and riparian quality.
Hydroptila Dalman, 1819
Because in the Iberian Peninsula larvae of several species distributed in the Mediterranean
coast remain undescribed (see González et al., 1992), and the difficulties to distinguish the
already described, we only present here results from pupae and adults collected.
19- Hydroptila gr. sparsa Curtis, 1834
MATERIAL STUDIED: 1P♂ (VIII)
Llobregat Basin: L68
TAXONOMIC REMARKS
The sparsa-group is highly variable (see Malicky, 1997). Our specimen is close to H.
angustata.
DISTRIBUTION AND ECOLOGY
Species from gr sparsa have been found in Europe, North of Africa and southwestern
Asia.
20- Hydroptila vectis Curtis, 1834
MATERIAL STUDIED: 8P♂2P♀ (II, IV, V, VIII, IX), 26♂10♀ (II, VIII, XI)
Tordera Basin: ToM9
Llobregat Basin: L60a, L61, L68
Foix Basin: F25
Almanzora Basin: AL4
Adra Basin: AD1, AD4
Guadalfeo Basin: GU6, GU7, GU9
DISTRIBUTION AND ECOLOGY
H. vectis is widely distributed around Europe, North of Africa and southwest Asia (see
González et al., 1992) as is in the Iberian Peninsula.
It is commonly present in different river reaches (Vieira-Lanero, 2000). In our basins H.
vectis have been found mainly in midstream and lowland reaches under a wide range of
environmental conditions, and very abundant when dense Cladophora masses were
present (Stroot, 1984).
Oxyethira Eaton, 1873
This genus comprises 5 species in the Iberian Peninsula, and many difficulties are found to
identify their larvae (see Vieira-Lanero, 2000). Specimens from this genus have found in reaches
from Segura, Aguas and Almanzora basins with an altitude of 210-920m.
