Pseudouroleptus

Pseudouroleptus Hemberger, 1985 (ref. ID; 4697 original paper, 7307)

Family Amphisiellidae Jankowski, 1979 (ref. ID; 7307)
Family Oxytrichidae Ehrenberg, 1838 (ref. ID; 7423)

[ref. ID; 2129]
The oral primordium originates in close contact with The ACR. The ACR commences anlagen formation within-row and originates from three rightmost anlagen. All dorsal kineties develop intrakinetally. Usually one post-peristomial cirrus developing from third anlage from right. One cirrus left of ACR. Transverse cirri row almost as long as body, parallels ACR, originates from single anlage. Caudal cirri present. (ref. ID; 2129)

Remarks

All ventral cirral anlagen right of the adoral membranelles are generated by long primary primordia indicated in the computer drawing by the lines within the cirral rows protruding from the posteriormost cirrus (row 1-6). The short row four in proter is most probably developed de novo and placed interphase between the anterior segment of the ACR (anterior segment of row six) and row five. The posteriormost cirrus of row four migrates to a postperistomial position and contributes to the forming of the oral primordium. Row five generates N3 with four streaks for proter and opisthe's new rows five and six. No anlage in the rightmost cirral row (row six) develops, as there is no anlage in the rightmost row in any oxytrichids and parakahliellids (except Paraurostyla weissei). Thus, all cirri of row six are unused (inactive) and obviously resorbed in late dividers. The anlagen for the right marginal row seven (RM) develop left of the oral row and only about half of the cirri are used for generating the new RM. Typical split dorsal kinety pattern right of the RM. (ref. ID; 7423)
