Hi everyone
Does somebody help me to find this manuscript?
Lena, H., Zaidenwersg, S.J., 1975. Tecamebas del delta del Parana(Argentina). Rev. Esp. Micropaleontol. 7, 519–537.
It is few old 🙁 but i really need it.
in discussion General Discussion / Twilight Zone discussion » Schoenbornia humicola - idiosomes or not?
Kasia Marciz asks this question:
I'm writing to ask about Schoenbornia humicola, more specifically, about the shell of the species.
I was trying to find information about the type of shell Schoenbornia humicol builds.
I contacted Ferry and he assured me about what I found in literature (paper attached, the original description as Pseudonebela humicola):
Schönborn describes the shell has having "siliceous plates as idiosomes" ("… mit Siliziumplättchen als Idiosomen"). Further he observed new-formed idiosoms in the cell plasm just like Euglypha ("Im Plasma der inaktiven Stadien beobachtete ich mehrmals vorgebildete Idiosomen ähnlich wie bei Eulgypha.").
Ferry Siemensma confirmed this.
Edward Mitchell believes these are not idiosomes because the platelets are not of uniform shape or size, at least according to the illustration used by Meisterfeld (2002). Rather they look at best as recycled idiosomes but may even be flat mineral such as mica.
Andrey Tsyganov agrees. "I agree with Edward that truly idiosomic species should have limited number of plates types of regular shape because they synthesize them. In case with Shoenbornia it seems that the plates are irregular in shape and size that rather points to extracellular origin of the plates than to unusual intracellular synthesis. "

Hi Anna,
I'm quite sure that what you observed would have been called Phryganella acropodia by many ecologists. I have frequently observed very similar tests ca. 30µm diameter together with larger ones ca. 50µm. Depending on which key you use they may even be included in the Cyclopyxis arcelloides-type.
Of course if you have living specimens with visible pseudopods you will know if they are Phryganella or not based on the pseudopod morphology. Empty tests are more tricky.
It is quite clear that these general morphotypes likely include several taxa. It would be very useful to conduct a study combining morphometrics, DNA barcoding and ecological observations to clarify this maze…

Thank you Mitchel ….

1 is most likely the egg capsule of a worm.
2 is the case of a bdelloid rotifer (genus Habrotrocha most likely).
3 is Euglypha
4 Trinema
5 most likely Phryganella (if the aperture is invaginated it would be Cyclopyxis)
6 Trigonopyxis
7 unclear, is the aperture on the top left?
For more precise identification it would be helpful to have the sizes.

Dear all,
Up to genus level I could identify…..I need up to species level identification…anybody can help?

For all it is worth - not sure if you need identifications below genus.
82-18a is a Nebela (Anush can help further)
82-18 Euglypha
82-8a Trinema
72h Euglypha
