Kurzbeschreibung Morphologie

Comparatively large animals of grayish yellow color. Body cylindrical. Trunk region 0.4 - 4 cm long. Introvert almost as long as trunk region. Entire body surface densely set with large (0.06 - 0.08 cm) dome-shaped black papillae. Papillae especially numerous on terminal and anal shields. Cephalon bear-ing crown of 21-29 tentacles in horseshoe-like arrangement around heart-shaped nuchal organ. Behind cephalon, introvert bearing specialized cuticular appendages (scalids), arranged into 15-30 circles. Two ventral and two dorsal retractors of introvert. Ventral retractors anchored in posterior third of trunk. Contractile vessel simple, with no lateral branches. Intestine with 10-18 loops, in dependence on animal size. Longitudinal musculature of body wall divided into pronounced, isolated longitudinal bands. Spindle-shaped muscle fastened at terminal end of trunk; 1-3 fixing muscles. Anus located somewhat in front of or level with nephrophores. Wing muscles well-developed. Rectal diverticulum absent. 2 nephridia fastened to body wall along 1/3 of their length via thin mesenterial filaments. Nephridiums 30 - 50 percentage as long as trunk (Ref. 1815).
