Neoconorbina

Mamo, Briony L., 2016, Benthic Foraminifera from the Capricorn Group, Great Barrier Reef, Australia, Zootaxa 4215 (1), pp. 1-123 : 83

Neoconorbina ? sp. 1 ( Fig. 20 :1–3)

Remarks. Collected specimens are tentatively assigned to Neoconorbina due to the trochospiral chamber arrangement and low, conical and convex test. The spiral side sutures are depressed and the chambers are inflated, large and covered by both fine and coarse perforations. The fine perforations predominantly occur around the outermost chambers whilst the coarse perforations are much less abundant and trace lines across all the spiral side chambers ( Fig. 20 :1–3). The limited number of available material are invariably juvenile specimens that are attached to reef rubble on the umbilical side making a specific taxonomic assignment tentative at best.

Distribution within study area. Neoconorbina ? sp. 1 was collected on Heron Reef flat along Transects 1 and 2. All collected specimens were alive at the time of sampling.
