Representatives of the family Strephocladidae have been considered as fossil relatives (i.e., stem-group) of Mantodea (mantises) based on characters of the forewing morphology. Here we describe new specimens from the Wellington Formation that we assign to the strephocladid species Homocladus grandisCarpenter, 1966. The range of morphological variation exhibited by the new material, in addition to wing morphology variability documented in extant mantises and roaches, suggest that H. ornatusCarpenter, 1966 and Paracladus retardatusCarpenter, 1966, reported from the same formation, are new junior subjective synonyms of H. grandis. We describe the first hind wing for this species based on a well-preserved specimen. It exhibits a combination of character states unique to dictyopteran insects.
