During a survey of freshwater fishes from Turkey two species of Acanthocephala, one of them new, were found. Pomphorhynchus tereticollis (Pomphorhynchidae) is reported at 24% prevalence in 37 Cobitis bilseli (Cobitidae) from Lake Beysehir, Konya, for the first time. The eoacanthoacaphalan Triaspiron aphanii gen. n. et sp. n. (Quadrigyridae), at a prevalence of 90%, is described from 29 Aphanius...

Genetic structure of an endemic tooth-carp fish, Aphanius farsicus from four different water bodies in the Maharlu Lake basin was investigated by applying five microsatellite markers. All of the five examined microsatellite loci showed polymor-phism pattern. A total of four alleles were detected at five microsatellite loci, with an average of 2.8 to 3.5 alleles per locus. Average values of obse...

Marine teleosts survive in their hyperosmotic environment by drinking the surrounding saline solution. They absorb salt (NaCl) and water through the wall of the gut, and excrete NaCl through the gills. This saves water to make up for the osmotic loss to the surroundings. When the salinity of the surrounding water is changed to a new level, the drinking rate (Maetz & Skadhauge 1968; Potts et al....

Stalacris n. gen. (Insecta, Grylloidea, Phalangopsidae) is described from South Africa using characters of morphology and male genitalia. This taxon, known from only two species, Stalacris meridionalis n. gen., n. sp. and Stalacris sp, is characterized by the unique structure of its forewings. These are prolonged distally as long, acute and more or less articulated processes, forming a kind of ...

Proctophyllodes huitzilopochtlii Atyeo & Braasch 1966 (Acariformes: Astigmata: Proctophyllodidae), a feather mite, was found on feathers collected from five hummingbird species in California. This mite has not been previously documented on feathers from Anna's (Calypte anna [Lesson 1829]) or Black-chinned (Archilochus alexandri [Bourcier & Mulsant 1846]) Hummingbirds. A total of 753 hummingbird...
