| Summary: | Olisthella contigua n. sp. (Figs 10 A, B, 12A) Material examined. Holotype: NIWA 95601, NIC Wellington, Stn T 39, 49.5033° S, 178.7433’ E, 995 m, N of Antipodes Island, 14 March 1981. Paratype: NIWA 98223, colony adjacent to holotype on same substratum. Etymology. Latin contiguus, neighbouring, near, alluding to the non-caudate, contiguous autozooids. Description. Colonies infertile, comprising up to seven non-caudate contiguous autozooids, one of them regenerated from within another autozooidal cystid; maximum colony spread c. 1.3 mm, hence small and spot-like. Individual zooids broadly subpyriform [ZL 432–589 (482); ZW 322–445 (407)], apparently with three pairs of lateral septula as well as one mid-distal and one midproximal. Gymnocyst encircling entire autozooid, fairly extensive proximally, moderate to narrow laterally, narrowest distally, sloping to the substratum. Cryptocyst comprising a very broad, flat shelf surrounded by a raised rim that is potentially almost circular, except where it is produced ... : Published as part of Gordon, Dennis P. & Taylor, Paul D., 2017, Resolving the status of Pyriporoides and Daisyella (Bryozoa: Cheilostomata), with the systematics of some additional taxa of Calloporoidea having an ooecial heterozooid, pp. 201-232 in Zootaxa 4242 (2) on pages 216-218, DOI: 10.11646/zootaxa.4242.2.1, http://zenodo.org/record/376356 ... |
