The nuclear groups lie in a voluminous perinuclear lacuna, the proximal membrane of which tightly applies to the nuclei leaving around them only a thin rim of ground cytoplasm. This membrane encircles each nuclear group separately and apparently holds the nuclei together. The micronuclei are filled with spongy condensed chromatin and limited by a conventional envelope with pores. The micronuclear chromatin is resistant to bleaching with BERNHARD's EDTA. Young macronuclei occur in some groups and contain small scattered chromocentres but no nucleoli; the chromocentres are readily bleached with EDT A. Adult macronuclei contain several nucleoli of usual structure (fibrillar core, granular cortex), several chromocentres and rarely a small sphere. The chromocentres are heterogenous: each one shows a dense cap. They become bleached with EDTA even after short exposure whereas nucleoli and the sphere retain contrast. The nuclei of <em>Tracheloraphis flexuosus</em> are smaller than those of <em>T. dogieli</em>, the similar European form.</p></div>","PeriodicalId":100118,"journal":{"name":"Archiv für Protistenkunde","volume":"147 2","pages":"Pages 173-180"},"PeriodicalIF":0.0,"publicationDate":"1996-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/S0003-9365(96)80031-5","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78196110","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It has two heterodynamic flagella, a flexible cell shape and a pronounced apical rostrum. So far it was regarded as dinoflagellate and called <em>Pronoctiluca phaeocysticola</em> (Scherffel) Pavillard. Our investigation revealed, however, that it belongs to the bodonids (Kinetoplastida). The mitochondrium is of the polykinetoplastic type. The two flagella insert in a deep flagellar pocket and have a paraflagellar rod. The cytostome, the cytopharynx and the rostrum are supported by various cytoskeletal elements, the most prominent of which is a reinforced microtubular band. A distinct rod organ(= microtubular prism, nemadesm) has not been found. It has extrusomes of the “lattice tube” type. A distinct glycocalyx and a spiral groove of the cell body are absent. It fits the description of <em>Hemistasia klebsii</em> Griessmann. We regard both as con-specific and introduce the combination Hemistasia phaeocysticola (Scherffel) Elbrächter & Schnepf, comb. nov.
