On the morphology, biometry and biogeography of Lamtopyxiscallistoma (Amoebozoa: Arcellinida).

ABSTRACT: The ultra-structure of the shell and the morphometric variability of soil inhabiting testate amoeba Lamtopyxiscallistoma from Madagascar were studied by using light- and scanning electron microscopy. The biometrical characteristic of the species was made on the basis of 75 specimens measured. In addition to the diameter of the shell, six other shell characters were described biometrically for the first time. The analysis of the variation coefficients shows that the studied population of L.callistoma is comparatively homogeneous and almost all measured characters are weakly to moderate variable (CV less than 10%). Scanning electron microscopy (SEM) studies on the shell ultra-morphology show that it has a smooth apertural surface with a thick layer of porous and fibrous organic cement and a
