N2 - Abstract—Comparative study of somatic musculature in illoricate rotifer Asplanchina girodi Guerne, 1888 and loricate Trichotria pocillum (Müller, 1776) has been carried out by the method of phalloidin fluorescence and confocal laser scanning microscopy. Similar layering of muscles is revealed, while significant differences are observed in other aspects. Postcoronal transverse muscle of A. girodi and the dorsal portion of the anterior circular muscle of T. pocillum serve as attachment sites for the refractor muscles. All retractors are formed by smooth muscles or striated muscles, except the lateral retractors of A. girodi, which are formed by the most powerful oblique muscles. In A. girodi there are three pairs of retractors, ten longitudinal muscles, and five circular muscles, with a thick muscular plexus connecting them. In T. pocillum there are four pairs of retractors, five transverse muscles, strong foot retractors, and an arched structure of the head region (new for rotifers). Eight pairs of dorsoventral muscles, as identified in T. pocillum, are completely absent in A. girodi.
