Habrotrocha cf. reclusa Milne 1886
Habrotrocha cf. reclusa, whirling specimen. This specimen has been photographed in a hyaline cell of the peat moss Sphagnum. The reinforcements of these cells (arrowheads) and the brim of the pore (arrow) are visible. (2)
Habrotrocha cf. reclusa, head of the above specimen. There is no interspace between dorsal antenna and the rostrum (arrow). In contrast to Habrotrocha roeperi this species has no eyespots. (2)
Habrotrocha cf. reclusa, after 3 days the hyaline cell in which the female had been housing there was now an egg. Still several bdelloid rotifers were on the micro-slide, but all had contracted, so the original female could not be identified.
Habrotrocha cf. reclusa, free-living specimen from (1), whirling, dorsal view. A species with very slenderr corona, about 1/2 of the head.
Habrotrocha cf. reclusa, left image: dorsal view of the head, focus plane on the upper lip which juts out (arrow) the trochal discs (arrowheads). Right: ventral view of the head of a creeping specimen; focus plane on the divided rostrum lamella. (1)
Habrotrocha cf. reclusa, whirling, ventral view. (1)
Habrotrocha cf. reclusa, left image: ventral view of the head and trophi (1); right image: trophi with dental formula 6/6 or 7/7.
Habrotrocha cf. reclusa, left image: foot with spurs. Right: foot and 3 toes. (1)
This species maybe confused with Habrotrocha roeperi, but lacks the conspicuous red eyspots in the rostrum which are typical for the latter species. Also the interspace between the rostrum and the dorsal antenna in H. roeperi is larger than in H. reclusa. Habrotrocha roeperi is reported to live (exclusively?) in the retort cells of Sphagnum, while H. reclusa can be found in the hyaline cells of the leafs of Sphagnum and free-living.
Location: NSG Ohligs, venn (1); Dolomites, Italy, (2)
Habitat:periphytic in sphagnum moss (1); in the hyaline cells of Sphagnum moss, together with Cephalodella dentata, Macrotrachela papillosa and Macrotrachela quadricornifera loricata (2).
