Strelkovimermis rubtsovi n. sp. and Strelkovimermis ozawindibi n. sp. (Nematoda: Mermithidae) parasitizing chironomid (Insecta: Diptera) adults eclosing from northern Minnesota glacial lakes.
Two new species of Strelkovimermis are described from chironomid imagoes eclosing from northern Minnesota glacial lakes. The 2 species are distinguished from the other 12 species in the genus by terminal mouths, rounded or nippled posterior ends, short buccal funnels, short terminal limbs of the S-shaped vagina, and presence of a bursal sleeve. Strelkovimermis rubtsovi n. sp. is distinguished from S. ozawindibi n. sp. by the presence of a dorsal protractor. Procladius (Psilotanypus) bellus (Loew) is the host of S. rubtsovi. The chironomid host of S. ozawindibi has not been determined. An artificial key is provided to distinguish the 14 species of the genus.
