Infraciliature and silverline system of the ciliate Pseudotrachelocerca trepida (Kahl, 1928), nov. gen., nov. comb., and establishment of a new family, the pseudotrachelocercidae nov. fam. (Ciliophora, Haptoria).

Abstract:

:The morphology, infraciliature and silverline system of Trachelocerca trepida Kahl, 1928 has been reinvestigated. The species was found in marine water (Yellow Sea) near Shanghai, Eastchina. Stained specimens (protargol) are characterized morphometrically. The shape of the extrusomes (toxicysts) and the structure of oral as well as somatic kinetids indicate that this species must be separated from the genus Trachelocerca. A new genus, Pseudotrachelocerca, characterized by an extensible neck, spindle-like toxicysts, irregular dorsal brush and widely meshed sliverline system, is thus erected. Based on the particular dorsal brush and silverline system the new family Pseudotrachelocercidae, nov. fam. is established. It can be possibly placed in the subclass Haptoria, order Spathidiida. However, a definite classification has to await fine structural investigations.
