Abstract

The SEM investigation of A. timmi is based on specimens from the coelomic cavity of the common goby Pomatoschistus microps (Kröyer) sampled in an estuarine area (Øra area) in the south-eastern part of Norway. The body is fusiform and subcylindrical, with a small terminal oral sucker and a reduced sunken ventral sucker situated about one-fourth along the body from the anterior end. The area between the suckers was characterized by transversal corrugations - partly due to body flexure - and distinct tegumental ridges and depressions. Posteroventrally and anterodorsally the tegument had a cobblestonelike appearance in contrast to the conspicuous longitudinal ridges posterodorsally. On the rim and surroundings of the oral sucker the tegument was irregularly convoluted with three types of distinct structures; domed aciliate papillae, pits, and domed ciliated papillae protruding or not protruding from pits. An aggregation of papillae was present encircling the ventral sucker. The tegument was unspined.
