New data indicate that larvae previously described as Spinadis Edmunds and Jensen and Spinadis wallacei Edmunds and Jensen are the larval stage of the prior named adults of Anepeorus simplex (Walsh) and are therefore synonymized. It is highly probable that larvae described as Acanthomola pubescens Whiting and Lehmkuhl represent the larval stage of Anepeorus rusticus McDunnough, but they remain to be reared. Anepeorus sensu novum and Pseudiron are placed in the subfamily Anepeorinae, and Raptoheptagenia (= recently associated Heptagenia cruentata Walsh adults and larvae previously thought to be Anepeorus) is placed in the subfamily Heptageniinae.
