We confirmed Ngoc-Ho’s (2003) observation that the male pleopod 1 of A. stirhynchus is simple but with an obsolete suture between two articles and a ridge that hints at an obsolete appendix interna (fig. 14a). Kensley reported for A. serratus the “pleopod 1 in both ... : Published as part of Poore, Gary C.
