Its relationship to M. sellnicki Balogh, 1959 needs further examination, since the species seem to stand very close to each other. Unfortunately, the present examination of mine did not permit a direct comparison between the two species. The drawing published by KRIVOLUTSKY lacks the well developed, heavily ciliate hair ta, the same is present on M. s

ellnicki, too. The grouping of hairs at the body-end is not characteristic, the present condition could have come about as a result of the preparation. It is quite likely that decisive differences are in the lengths of sensillus and the position of hairs te-ti on the notogaster. (Fig. 25.) Tuberoppia rotundata (Golosova, 1970) Zool. Zsurn., 49: 697-698, figs. 3: 1-4. (Oppia) Zool. Zsurn., 53: 1885-1886, figs. 2-3. (Tuberoppia) The figures published by GOLOSOVA are all simplified and rather schematic. Thus, e. g. the transversal costulae much weaker than the costulae proper. Dorsosejugal margin of notogaster with a larger and 2-3 smaller teeth. Inwards from the basal papillae in the interbothridial region a strong line is running. Hair ta is not shorter, .nor is it thinner than other notogastral setae, though it is ciliate. The principal character of this genus: marginal teeth of notogaster, seems to be insufficient for unequivocal separation. Perhaps the genus will have to be merged, but for conclusive evidence further examinations are necessary. (Fig. 26.) REFERENCES BALOGH, J. (1959): Neue Oribatiden aus Ungarn (Acari). - Ann. Univ.
