Morphological studies on two rare soil amoebae Deuteramoeba algonquinensis and D. mycophaga (Gymnamoebia, Amoebidae) |
Martin Mrva Department of Zoology, Faculty of Natural Sciences, Comenius University, Bratislava, Slovak Republic Summary The long-time unnoticed soil amoebae Deuteramoeba algonquinensis (Baldock, Rogerson et Berger, 1983) Page, 1987 and D. mycophaga (Pussard, Alabouvette, Lemaitre et Pons, 1980) Page, 1988 were recorded in the terrestrial habitats of Malé Karpaty Mts. (Slovakia) and its morphology investigated using live observations at the light microscopical level. The polypodial and monopodial locomotive form of D. algonquinensis is typical with a large hyaline cap on the anterior ends of the pseudopodia, spherical nucleus possessing many distributed nucleolar particles and refractile paired inclusions in the cytoplasm. D. mycophaga has a broad monopodial or polypodial locomotive form with a shallow hyaline cap on the anterior end, vesicular nucleus and many elongated bipyramidal crystals making its cytoplasm dense in appearance. Additional data and details of the morphology of both species were described and illustrated.
