Nov.) - Relevant material - ? Anchistia danae Stimpson, 1860 : 41 [108] (Tahiti; cf. remark). - Remark: Concerning Anchistia danae Stimpson, Bruce, personal communication, has the following remark: "The type material of Stimpson's species is long gone and I do not think that the question of this species can now ever be resolved. It probably is a Periclimenes, at least. It is probably a well known species under some other name, possibly one of the P. grandis group (Kemp, 1922: 138). It lacked both second pereiopods and the ambulatory pereiopods, so is not really worth wasting further time on. The sooner it is completely forgotten the better..." - Li, 2008: 215 (Marquesas Is.
