Family Rhyacophilidae

Rhyacophila sp.

Berbaga: 06.iv.2018, 5 larvae, 1♂, 2♀♀ pupae; 02.x.2018, 2 larvae; 05.xii.2018, 1 larva; 16.i.2019, 4 lar- vae; 12.ii.2019, 3 larvae; 30.iv.2019, 7 larvae 21.vi.2019, 11 larvae; 06.vii.2019, 1 larva. Inoughissen: 26.vi.2018, 1 larva; 23.xi.2018, 3 larvae; 23.xii.2018, 4 larvae; 6.vi.2019, 10 larvae, 1♀ pupa. Yabous: 02.i.2019, 3 larvae; 21.vi.2019, 3 larvae.

The larvae belong to the Pararhyacophila group sensu Döhler (1950) with tetrafilament (four-branched) abdominal gills and resemble those of the Corsican endemic Rhyacophila tarda Giudicelli 1968 . Furthermore, the head coloration is similar to that of Rhyacophila munda McLachlan 1862 . However, the sword process is long and not short as in R. munda . The mature female pupa did not key with any of the known West Palaearctic Rhyacophila species. We speculate that this could be a new species or a hitherto unknown female and larva; however, additional adult material is needed to confirm the identity of this species.
