The caddisflies (Insecta, Trichoptera) of Isla de Margarita (Venezuela) with description of two new species

Intensive sampling on the three perennial streams of Isla de Margarita enabled identification of 11 caddisfly species (most of them new records for the island), two species in the genera Neotrichia and Leptonema being described as new. The new Neotrichia belongs to a group comprising several species described from Surinam; the new Leptonema, although belonging to a small group of Amazonian species, is quite distinctive in several respects. There is presently incomplete evidence about the existence, or former existence, of 8 additional species in the island's fauna.
