Dipseudopsidae

Abstract: Lebanese amber contains a diverse biota from the Lower Cretaceous, and more than 150 families of arthropods have been reported as inclusions. Amongst these, caddisflies (Trichoptera) are very scarce inclusions, consisting of a few indeterminate fragments and only two inclusions that permit clear descriptions of new species. We describe the first two Trichoptera species from Lebanese amber, belonging respectively to Dipseudopsidae (Phylocentropus succinolebanensis n. sp.) and Ecnomidae (Ecnomus cretacia n. sp.). Previously, the oldest fossil representatives of both families were known from the Upper Cretaceous amber of New Jersey for Dipseudopsidae and from the Eocene Baltic amber for Ecnomidae.

Abstract: The present study surveyed adult caddisflies in Ile-Ife to identify the species that contribute to the fauna of freshwater ecosystems of this area and to determine their seasonal abundance. Adult caddisflies were collected between June 2009 and November 2010 from eight sampling stations established at different locations using an improvised light trap. A total of 754 adult caddisflies that were collected represent six species in six genera and three families. The species identified are Dipseudopsis conformis Navas, 1931, Polymorphanisus similis Ulmer, 1912, Aethaloptera dispar Brauer, 1875, Ceraclea njalaensis (Mosely, 1933), Pseudoneureclipsis mlangensis Mosely, 1939 and Cheumatopsyche digitata (Mosely, 1935). The Hydropsychidae was represented by three species belonging to three genera. The hydropsychid C. digitata was the dominant and most widely distributed species, occurring at all sampling stations with the highest frequency of occurrence (51%). On the other hand, P. mlangensis (Dipseudopsidae) was the least abundant with the lowest frequency of occurrence (0.8%).

Abstract: Based on a collection of Trichoptera from the Finaransoa Province on Madagascar, the following three new species are described and illustrated: Pseudoneureclipsis madagascariensis, spec. nov. (Dipseudopsidae), Madagocerum flinti, spec. nov. (Odontoceridae), and Cheimacheramus ranomafanensis, spec. nov. (Sericostomatidae). This report represents the first record of the genus Pseudoneureclipsis Ulmer from Madagascar, the fourth known species of the endemic Madagascan genus Madagocerum Olah & Johanson, and the third known species in the Madagascan and South African genus Cheimacheramus Barnard.
