Target Group: Stamp collectors specialized in issues of Northern European countries, experts, dealers, thematic collectors, study groups, teachers Additional Information: rd edition, in colour pages Format: x mm, Hardcover First day of sale: 7 September ISBN: Language: German.
Body color light yellow with greenish anterior proboscis. Black pigmented eyespots present. Anterior end sharply decreasing in width to form distinct proboscis, with sensory cilia, papillae and numerous circular folds, and denoted by paired transverse tufts of cilia at base. Posterior tip with thin tail and terminal sensory cilia. Intestine non-ciliated, often with diatoms and protozoa. Rhabdites may be present in the anterior end.
Male reproductive system including a single testis, which may be bilobed in some specimens. Stylet weakly arched connecting to seminal vesicle. Notes: Brinkmann [ 74 ] pg 66 argued that both Alaurina viridirostrum and A. Microstomum crildensis Faubel , ; Fig 18E. Body to 1. Solitary animal 0. Body colorless; pigmented eyes absent. Ends rounded, posterior with adhesive papillae. Constriction at level of brain at ciliary pits. Preoral intestine short, not quite reaching level of brain. Rhabdites and nematocysts absent. Single testis, located at the very caudal end of the animal.
Single ovary present. Notes: Three specimens identified as Microstomum crildensis were collected from Swedish Skagerrak coast. Unfortunately, none of these specimens displayed sexual organs, and so the reproductive system—most importantly the male stylet—could not be used to corroborate identification. However, in every other respect, these specimens matched the original description and drawings, including: overall body shape including a body constriction at the ciliary pits, presence adhesive tubes on the posterior end only, absence of rhabdites, and small preoral intestine.
The habitat—eulittoral muddy sediments of the North Sea—was also consistent. Currently, the only other species of Microstomum with posterior adhesive papillae that entirely lacks rhabdites are M. Microstomum curinigalletti sp. Body length 1. Anterior body end ochre to dark yellow-orange. Anterior end conically rounded; posterior end blunt with numerous adhesive papillae.
Preoral intestine very short. Few rhabdites scattered across the body. Microstomum davenporti Graff , Body colorless or whiteish with a yellow-ocher intestine. Anterior conically pointed; posterior end broad with numerous adhesive papillae. Ciliary pits present but very shallow. Preoral intestine long.go to link
