Demosponges from the sublittoral and shallow-circalittoral (<24m depth) Antarctic Peninsula with a description of four new species and notes on <em>in situ</em> identification characteristics
Specimens were collected by SCUBA diving from 22 sites along the Antarctic Peninsula, spanning latitudes from Diomedea Island (62°12.185’S) to Jenny Island (67°43.325’S). The aims of the survey were to record the sponge biodiversity of the sublittoral and shallow-circalittoral and to provide information on in situ identification features. In total 24 sponge species were recorded, ranging from 0 to 12 species per site. The most widespread species were Dendrilla antarctica (10 sites), Sphaerotylus antarcticus (11 sites); and Mycale (Oxymycale) acerata (13 sites). Four species new to science were discovered and are described here: Megaciella cardenasi sp. nov., Crella (Crella) hennequinae sp. nov., Hymedesmia (Hymedesmia) noramaloneae sp. nov., Clathria (Clathria) priestleyae sp. nov. Suberites topsenti (Burton, 1929) is reassigned to Hemimycale topsenti (Burton, 1929) comb. nov. General habitat notes are provided for the survey sites, many of which were previously unsurveyed.
