Short description.
Colony encrusting, autozooids rectangular with rounded distal edges, disposed in quincunx and separated from each other by a raised edge. Cryptocyst granular and porous. A pair of tubercles frequently present at the proximal corners. Avicularia absent in this material.
Geographic distribution.
Alagoas and Bahia states (
Vieira
et al
. 2016
;
Bastos
et al
. 2018
; present study).
Remarks.
Specimens found at Abrolhos were very similar to those described by
Winston
et al
. (2014)
and
Vieira
et al
. (2016)
.
Labioporella tuberculata
resembles
L. dipla
Marcus, 1949
, also described from
Brazil
(
Espírito Santo
State), but
L. dipla
has a prominent tubercle on the distal wall beneath the operculum, smaller zooids and lacks tubercles at the proximal corners of the zooids. Another similar species is
L. granulosa
(
Canu & Bassler, 1928b
)
, described from the Gulf of
Mexico
, which also lacks corner tubercles.
