Dear Juan and Bill, and others interested,
Hymenamphiastra De Laub. 1930 as a genus will be merged with
Acanthancora Topsent, 1927 in the forthcoming Systema Porifera. So
prepare yourself for the combination Acanthancora cyanocrypta.
Hymedesmia aenigma Lundb. is the type of a genus Ferrerhernandezia De
Laub. 1936, which will be likewise merged with Acanthancora, so its
name is proposed to be Acanthancora aenigma.
As for the possible synonymy of both, I leave that to those who are
familiar with fresh material, like Bill.
>I am not aware of any synonym for Hymeniamphiastra cyanocrypta. However,

>I have looked at both in Cal and BC are larger (to 310 and 380 microns)than

>from Hartman's note of mean length of 150-190 microns.

>We have found it in British Columbia in an intertidal cave (Execution Rock)
>in Barkley Sound and diving off Cadman Island, Kanu Inlet, Queen Charlotte
>Islands.
>Jeff Goddard found a yellow form at Cape Arago, Oregon. While the blue
