Ascidia empheres Sluiter, 1895 View in CoL

Ascidia empheres Sluiter, 1895: 155 View in CoL ; Kott, 1985: 35 and synonymy.

Distribution. New records: Queensland (Moreton Bay: Dunwich, QM G308551; Victoria Point, G308560; Wellington Point, Raby Bay). Previously the species had not been recorded south of the Capricorn Group.

Description. The dark grey colour of this species becomes more intense with fixation and preservation. A tongue of dark pigment projects back from each of the 8–10 branchial and seven atrial lobes into the siphon linings. Small projections, alternating with the larger rounded lobes around each aperture, have a central yellow dot, possibly a terminal ampulla of a blood vessel. The anal opening is always posterior to the pole of the gut loop and the neural gland and ganglion are halfway between the simple dorsal tubercle and the atrial aperture (as previously described).
