Ecology and distribution. Staurotheca glomulosa had been previously reported at depths between 55 and 157 m (Peña Cantero & Vervoort 2003); present material collected at depths from 103 to 371 m. Basibiont for colonies of P. belgicae (present material). Peña Cantero & Vervoort (2003) reported it off Buckle Island; present material found off Young and Sturge islands.
description
Measurements (in µm). Hydrotheca: abcauline wall 630 – 700, free part of adcauline wall 100 – 130, adnate part of adcauline wall 730 – 780, adcauline wall 830 – 910, diameter at aperture 230 – 270.
discussion
Remarks. The planar colonies are polysiphonic and the presence of anastomoses gives them a mesh-shaped appearance. The hydrothecae are arranged in decussate pairs, forming four longitudinal rows.
