Description
Colony encrusting, unilaminar. Autozooecia vase shaped or subhexagonal, arranged quincuncially (
Fig. 9A
). Cryptocyst extensive, flat, surface coarsely granular and with fine pseudopores, slightly bulging in middle, sinking distally and near opesiules, bordered by thick, raised mural rim. Opesiules small, slit like, placed at proximolateral corners of orifice near lateral margins. Orifice semielliptical, wider than long, arched distally, proximal edge concave. Ooecia small, semi-immersed, smooth, with semicircular frontal surface (
Fig. 9B
). Avicularia not observed.
Remarks
All the essential characters agree with
Micropora vredenburgi
Guha & Gopikrishna, 2005
. However, the interzooecial avicularia observed by Guha & Gopikrishna (2005) were not noticed in the present specimens.
