Paragastrostyla

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

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

[ref. ID; 2129]
The oral primordium originates in close contact with the ACR. The ACR commences anlagen formation at its posterior end and originates from three rightmost anlage. All dorsal kineties develop intrakinetally. More than one cirrus left of ACR. Caudal cirri present, transverse cirri absent. (ref. ID; 2129)

[ref. ID; 7307]
The ACR originates from three rightmost anlagen. More than one cirrus left of ACR. Caudal cirri present, transverse cirri absent. Single species, P. lanceolata Hemberger, 1985 (description of morphogenesis in the Hemberger dissertation, 1982). The alignment of the ACR is least perfect in this species; data indicate that an additional anlage may be involved in forming the ACR. (ref. ID; 7307)

Remarks

Morphogenesis: Unique cirral pattern. The anlagen 1-5 possibly develop by long primary primordia. The rightmost ventral row seven consists of three fronto-terminal cirri only. Oxytrichids usually possess in the rightmost row four cirri, however, only two in the anterior position. In contrast to the other oxytrichids, no transverse cirri are described. (ref. ID; 7423)
