Figure 8 E, F; Figure 9 A – C # 2655 A, colony 7.5 cm across. Tunic pale reddish, almost completely covered with fine whitish sediment. Zooids embedded in common tunic, only the separate siphons emergent. Small tubercles around edge of siphons. In the living colony the siphon lining has red striping. A large zooid out of tunic 3 cm long with wide gut loop, many narrow plications on stomach, no caecum. Rectum very long, anus with 14 rounded lobes but also bilobed. Gonads six on left, 34 on right, very loosely attached to body wall, elongate and sausage shaped. No endocarps in gut loop or body wall. With small Pyura curvigona Tokioka, 1950 (# 2655 B) embedded in colony (see Fig. 11 E). Distribution: New Caledonia, Majuro, Australia, Hawaii.

Ascidians collected during the 2013 Singapore Strait International Marine Biodiversity Workshop

checklist

This dataset contains the digitized treatments in Plazi based on the original journal article Lambert, Gretchen, Lee, Serina Siew-Chen, Teo, Serena Lay-Ming (2021): Ascidians collected during the 2013 Singapore Strait International Marine Biodiversity Workshop.

Abstract

During the 2013 Singapore Strait International Marine Biodiversity Workshop, hundreds of ascidians were collected along with numerous other marine phyla. Collections were made intertidally as well as subtidally by snorkel, SCUBA, trawling and dredging. While many ascidian specimens remain unidentified, 14 aplousobranchs, nine phlebobranchs and 17 stolidobranchs have been identified; a surprising 50% of these comprise 20 new records for Singapore. An additional new record of the phlebobranch Perophora namei collected from the same area in 2014 and 2015 is included here. Of the 21 new records, Aplidium cf. grisiatum, Distaplia regina, Euherdmania cf. digitata, Cnemidocarpa irene, Monandrocarpa monotestis and Polyandrocarpa rollandi are also first records for the entire South China Sea region.
