Pimpinella bengalensis et P. Tessmannii spec. nov

Clostridium sticklandii nov. spec.

Taxonomic studies on three marine pleurostomatid ciliates, Litonotus bergeri nov. spec., L. blattereri nov. spec. and L. petzi nov. spec. (Ciliophora, Pleurostomatida) from North China Sea.

The morphology and infraciliature of three pleurostomatid ciliates, Litonotus bergeri nov. spec., L. blattereri nov. spec. and L. petzi nov. spec., collected from mariculture ponds near Qingdao (Tsingtao), China, were investigated using live observations and the protargol impregnation method. These new species are distinguished from their congeners by a combination of characters including the t...

Linnaeomyia hortensis gen. et spec. nov. (Diptera: Cecidomyiidae, Porricondylinae) from a backyard site in Öland, Sweden.

A new genus containing a single new species of Porricondylinae (Diptera: Cecidomyiidae) is described and named Linnaeomyia hortensis gen. nov., spec. nov. The sole known specimen of L. hortensis, a male, was Malaise trapped in a backyard site on the Baltic island of Öland, southeast Sweden, in summer 2014. Morphological evidence supports our hypothesis that Linnaeomyia is most closely related t...

Morphology of two new marine peritrich ciliates from Yellow Sea, Pseudovorticella dingi nov. spec. and P. wangi nov. spec., with supplementary descriptions of P. plicata, P. banatica and P. anomala (Ciliophora, Peritrichia).

Two new marine peritrich ciliates, Pseudovorticella dingi nov. spec. and Pseudovorticella wangi nov. spec. were collected from coastal waters of Qingdao, China. Their living morphology, infraciliature and silverline system were studied using light microscopy and silver staining methods. Pseudovorticella dingi is characterized mainly by the apically located contractile vacuole and the presence o...
