Abstract

Mallomonas mangofera was frequently found in hualves, lakes and bañados of the Chilean lake district in July 1981. Observations of the fine structure of the scales with both transmission and scanning electron microscopy strongly suggest that specimens with a well developed network and conspicuous macropores on the shield belong to a separate forma,M. mangofera f.foveata f. n. An emended description of the type species and the general characteristics of theM. mangofera group are given. Three other taxa,M. mangofera var.sulcata var. n.,M. mangofera f.gracilis f.n. andM. alveolata sp. n. are also described.
