Dictyaulus marecoi
“The species is named after the MAR-ECO expedition.” Tabachnick & Collins (2008)
“The two previously known species of Dictyaulus, D.elegans Schulze, 1895 (NW Indian ocean) and D.starmeri Tabachnick & Levi, 2004 (SE Pacific ocean), have more types of microscleres than D.marecoi: three types of discoidal microscleres, one or two types of sigmatocomes. The new species has neither large discohexasters, as in D. elegans, nor discasters corresponding to them, as in D. starmeri. Further distinguishing D. marecoi are the large anchorate discohexasters (found in the holotype only) and the pileate discohexasters with many secondary rays having very small discs. The spicule measurements of corresponding spicules are very similar in these three species.” Tabachnick & Collins (2008)
