Abstract Aim In the present study, structure of benthic invertebrates in ponds presence and absence Nile tilapia was evaluated. Methods The macroinvertebrates physicochemical parameters were analyzed for a period eight weeks, every 15 days, two (one with fish other without fish). Benthic sampled artificial substrate samplers, made cheap common materials, like expanded clay, loofah leaves gravel...

We report five new species records from the Comoros Archipelago. Two of the species are known from outside the Archipelago, Hydroptila cruciata Ulmer (Hydroptilidae) and Anisocentropus voeltzkowi Ulmer (Calamoceratidae), and three species are described as new to science: Pisulia stoltzei ,new species (Pisuliidae), and: Chimarra mayottensis, new species and Chimarra koulaeensis, new species (Phi...

Benthic macroinvertebrate communities of Lake Tanganyika tributaries in pristine, forested, and impacted, deforested, watersheds were examined. Samples were collected using a Surber-sampler, and identified under a dissecting microscope. Family biotic indices (FBI), percent of Ephemeroptera/Plecoptera/Trichoptera (%EPT), relative Chironomid abundance (RCA), and taxa richness of five impacted str...

The tributaries of the Olifants River draining the Cedarberg Mountains in the Western Cape are well known for their diverse fauna of endemic freshwater fish. Aquatic ecosystems in the region have also been identified as being particularly important in terms of ecosystem conservation. Recent surveys of aquatic macroinvertebrates have indicated that the region is rich in Trichoptera, with a numbe...

The Japanese Paduniella Ulmer species are reviewed with descriptions of 3 new species. Paduniella communis Li & Morse and P. uralensis Martynov are recorded from Japan for the first time and redescribed. Records of P. amurensis Martynov from Japan are based on misidentification. Illustrations of male genitalia are provided for

Notalina roraima Holzenthal 1986 was described on the basis of a single holotype specimen from the Pantepui Region. The species is a member of the endemic Neotropical long-horned caddisfly (Trichoptera: Leptoceridae) subgenus Notalina (Neonotalina) Holzenthal 1986. We present new records of this species and describe some morphological variation in the male genitalia. Moreover, we describe and i...
