Panningia trispicula Thandar 2008

( Fig. 22 A – C)

Panningia trispicula Thandar, 2008: 29 , fig. 11.

Material examined. Non-type material: IE-2007-773 (1 specimen, sampled between Majunga and Cape Saint André) ; IE-2007-761 (1 specimen sampled in front of Majumga); IE-2007-819 (1 specimen, sampled in front of Nazendry Bay ) .

Remarks. The three specimens before us, 100 mm long and 12.5 mm wide with maximum circumpherence of 53 mm, 52 mm long and 7.5 mm wide with maximum circumspherence of 36 mm and 12 mm long and 2 mm wide with maximum circumspherence of 3 mm most possibly are Panningia trispicula Thandar, 2008 which was hitherto known only from the holotype and the paratype that were sampled off Mossel Bay (34°10' S, 23° 32' E), at 97 m depth. Some differences between our largest specimens and the types are apparent: the largest plates of our largest specimens range from 0.7 to 1.1 mm in length and 0.5 to 0.7 mm in width, whereas those of the types are 0.28 to 0.445 mm long. Also the deposits in the tentacles of the types are less complex than those in our largest specimens.
