Table 1 – Localities and main morphological traits of the Reteporella species occurring in the Azores Archipelago
Species | Report of presence | Morphological characteristics |
|---|---|---|
R. tristis (Jullien, 1903) | Princess Alice Bank São Jorge Terceira São Miguel Santa Maria | ♣ Oval suboral avicularia. ♣ Oval avicularia on the abfrontal side and rarely on the frontal side. ♣ Large spatulate avicularia in some fenestrae. |
R. oceanica (Jullien, 1903) | Condor Bank Pico | ♣ Oval suboral avicularia ♣ Large triangular avicularia on the frontal and abfrontal sides, with three small, subrounded foramina in the extensively calcified palate. ♣ Occasional small avicularia on the abfrontal side. |
R. atlantica (Busk, 1884) [= R. gracilis (Jullien, 1903), likely its junior synonym)] | Flores Condor Bank Princess Alice Bank Chino Bank Faial Pico São Jorge Terceira São Miguel Santa Maria | ♣ Three morphotypes of suboral avicularia: small oval, intermediate size triangular, and occasionally a gigantic one in ovicellate zooids. ♣ Oval and elongate triangular avicularia on both the frontal and abfrontal sides. |
Reteporella rara (Jullien, 1903) | ? | ♣ Large oval suboral avicularia. ♣ Reticulate surface structure. |
Reteporella sp. 1 | Terceira | ♣ Oval suboral avicularium pointing proximomedially. ♣ Triangular avicularia on the frontal and abfrontal surfaces. ♣ Very short pseudosinus next to the suboral avicularium. ♣ Open-branched colony, with cylindrical branches. |
Reteporella sp. 5 | São Miguel | ♣ Small oval suboral avicularia. ♣ Large triangular avicularium on abfrontal side, positioned on distinctly swollen cystid, with three small subrounded round foramina in the extensively calcified palate. |
Reteporella sp. 6 | Gigante Bank Terceira | ♣ Oval suboral avicularia. ♣ Small oval and larger triangular avicularia on the frontal and abfrontal sides. ♣ Absence of giant avicularia. |
Reteporella sp. 7 | Gigante Bank São Miguel Formigas Santa Maria | ♣ Small oval and larger triangular suboral avicularia. ♣ In triangular avicularia, the palatal area distal to the crossbar is wider than in R. atlantica. ♣ Absence of giant avicularia. ♣ Pseudosinus length and fenestra size greater than in R. atlantica. |
