Comments There is a description of the genus p. 400 (p. 112 of reprint), and description of five species of Actinoptychus p. 409-410 (p. 121-122 of reprint): A. hexapterus, A. nonarius, A. denarius, A. vicenarius, A. jupiter; there is also an illustration of A. senarius (I/I/27) and A. nonarius (I/III/22). No type is designated in the original publication. Boyer gives A. senarius as the type accompanied by a querry. Actinoptychus was first introduced (but not validly published) in Ehrenberg 1841 (ref. 000953) as a subgenus of Actinocyclus. No diagnosis was given, and four species were included in the group p. 137, 140-141: Actinocyclus (Actinoptychus) senarius, A. sedenarius, A. octodenarius and A. duodenarius.
