Female Microtetrameres sp. (Nematoda: Spiruridae) are reported for the first time, apparently, from the bronzed grackle, Quiscalus versicolor, and the eastern meadow lark, Sturnella magna. The hosts were collected in Chickasaw County, Iowa. One of 3 meadow larks and 1 of 13 grackles examined were infected. No males were recovered.
