(Hrabe, 1934)
Description
Large smooth, pink worms. Anterior dorsal bundles with hair and pectinate chaetae. Hair chaetae very finely pilose, anteriorly 1-5 per bundle, posteriorly disappearing already before midbody. Anterior pectinate chaetae (2-3 per bundle) with equal ordinary teeth and with as long, or shorter intermediate teeth. Anterior ventral chaetae 2-4 per bundle. Posterior crotchets very thick both in dorsal and ventral bundles, with enlarged, bent lower tooth. In mature individuals, ventral chaetae absent from XI. Spermathecal chaetae in X thin, straight and stick-shaped but with furrow on their distal part, 193-215 µm long. Length 20-30 mm, segment number 80-95. Dorsal chaetae, both hair and pectinate chaetae, have an intermediate appearance between Psammoryctides barbatus and Psammoryctides albicola. Hindbody can look similar in all three species.
