wallaceina wallaceina wallaceina is a genus of parasitic flagellate protist belonging to the family trypanosomatidae. this generic name is a replacement name for proteomonas podlipaev, frolov et kolesnikov, 1990 because the latter proteomonas was already attributed to a cryptomonad. wallaceina is a taxonomic patronym honoring the protistologist franklin g. wallace, a pioneer in the modern taxonomy of trypanosomatids. wallaceina scientific classification domain: eukaryota clade: diphoda clade: discoba superphylum: discicristata phylum: euglenozoa subphylum: glycomonada class: kinetoplastea subclass: metakinetoplastina order: trypanosomatida family: trypanosomatidae genus: wallaceinabulat, mokrousov and podlipaev 1999 species w. brevicula (frolov & malysheva 1989) frolov, kolesnikov podlipaev 1999 w. collosoma (wallace et al. 1960) votýpka & lukeš 2014 w. inconstans (podlipaev, frolov & kolesnikov 1990) w. podlipaevi (podlipaev 1985) malysheva & frolov 2009 w. raviniae votýpka & lukeš 2014 w. rigida (podlipaev, malysheva & kolesnikov 1991) votýpka & lukeš 2014 w. vicina malysheva & frolov 2004 synonyms proteomonas podlipaev, frolov and kolesnikov, 1990 non hill & wetherbee 1986 wallaceina is a monoxenous parasite of insects. other one-host trypanosomatids from hemipteran and dipteran insects have been traditionally placed in genera blastocrithidia, crithidia, leptomonas, herpetomonas, and rhynchoidomonas. wallaceina is characterized by endomastigote morphological forms, whereas epimastigotes and opisthomastigotes are features of the genera blastocrithidia and herpetomonas, respectively. comparison and phylogenetic analysis of 18s ribosomal rna and glycosomal glyceraldehyde-3-phosphatedehydrogenase sequences of trypanosomatid taxa indicate that the genus wallaceina is polyphyletic. it is therefore suggested to reassign wallaceina species either to crithidia brevicula (for wallaceina brevicula, w. inconstans, w. vicina, and w. podlipaevi) or to the newly proposed genus wallacemonas (for wallaceina collosoma, w. rigida, and w. raviniae).
