Macrotrachela punctata, focus plane on the granulated integument. It is a remarkble coincidence that the only Adineta-species (A. tuberculosa) with an integument that is also very conspicuous has been found in the same environment/ sample.
Macrotrachela punctata, 4 images of the anterior part of several specimens. Upper images: different aspects of the upper lip; left: specimen from (2); also visible is the mastax with ramate trophi and dental formula (DF): 2/2, right: specimen from (3).
