dc:description"Fig. 1. Akrophryxus acinaces sp. nov., holotype (SMBL-V0649) and paratype (SMBL-V0652) females, attached to the right and left antennules of host, Pycnoplax surugensis (Rathbun, 1932), respectively; images taken while alive. A, Dorsal view; B, en-face view; C, close-up of paratype on left antennule; D, posterior view of holotype attached to host antennule; E, lateral view of holotype, removed from host; F, posterior view of holotype, removed from host. Scale bars: 3mm (A, B); 1mm (C–F).";

A, Posterior view; B, lateral view; C, anterior view (opposite side to that shown in A), host antennule facing viewer; D, top down view; E, lateral view of dissect- ed specimen shown host antennule in-situ (Mo=Mouth), dashed circles show developing eggs in ovary; F, lateral view of dissected specimen with antennule removed, dashed circles show developing eggs in ovary; G, host antennule removed from holotype.
