An outline on distribution and hosts of the cystoid nematodes of Ataloderinae Wouts, 1973 and Meloidoderinae Golden, 1971 Ghaderi, Reza Zootaxa 2019 2019-09-04 4664 3 339 350 3160e376-3afd-4fe8-b08c-80894d562b6f Wouts & Sher, 1971 Wouts & Sher 1971 [151,537,1701,1728] Chromadorea Heteroderidae Sarisodera GBIF Animalia Rhabditida 4 343 Nematoda genus   Luc et al.(1973)described  S. africanafrom guinea grass (  Panicum maximum, Poaceae) from Senegal, but Baldwin & Bell (1985)emended the diagnosis of  Sarisoderato exclude cysts, which do not form in the typespecies,  S. hydrophila.They then transferred  S. africanato their new genus  Afenestrata. Later, Mundo-Ocampo et al.(2008)synonymized  Afenestratawith  Heterodera. The histopathology of two populations of  S. hydrophilawas examined on willow (  Salix lasiolepisEenth., Salicaceae), cottonwood (  Populus fremontiiWats., Salicaceae), and ironwood (  Lyonothamnus floribundusGray, Rosaceae) using light microscopy as well as scanning and transmission electron microscopy.  S. hydrophilainduces formation of a single uninucleate hypertrophied cell (giant cell) which varies only slightly among the three hosts. Cell wall ingrowths, such as those associated with host responses to certain other plant-parasitic nematodes, were not observed in giant cells induced by  S. hydrophila( Mundo-Ocampo & Baldwin 1983a).
