Genus Haplomyxa Dellinger, 2014

Diagnosis: Naked multinucleated cell of various shape, cell body from globular to flat extended shape, usually massive and elongated, may be with few branches and/or holes but not extensively and constantly reticulated, cytoplasm with several alternatively opposite flows, producing a few large and extended pseudopodia (“veins”) and a network of interconnected filopodia (reticulopodia) all forming from any part of the cell and bearing granules and attached particles circulating bidirectionally (granuloreticulopodia), numerous cytoplasmic granules and contractile vacuoles, migration and division by translation within large pseudopodia, making covered cysts. Freshwater.
Type species: Haplomyxa saranae Dellinger.

Etymology: From the Greek haplo (single, simple) and myxa (slime), to report on its massive shape, different from the reticulated shape of Reticulomyxa.

Other species: At least two other undescribed species reported by N. Hülsmann might be of the same genus (Hülsmann 1984; Kaufmann D, Wylezich C, Hülsmann N (2006) Deutschen Gesellschaft für Protozoologie: Protist Diversity: Past, Present and Future 8-11 March 2006, Liebenwalde, Germany, Abstract KV4) and one species only known by an environmental rDNA sequence reported from Lake Neuchâtel (Switzerland) (Holzmann et al. 2003).
