Genus
Lageniporina
gen. nov.
Etymology.
Latin,
lagena
, large narrow-necked jar or bottle and
porus
, hole, plus the suffix -
inus
, thus made of pores, a common ending for cheilostome names.
Diagnosis.
Uniserial celleporid with flask-like zooids, tubular pores and an ooecium placed on the 'back' of the peristome into which it opens. No avicularia or oral spines.
Description.
Colony encrusting, unilaminar, uniserial, branching. Zooids elongate-oval, convex, thickly calcified. Scattered frontal pores, some on short tubes; a few marginal pores. Primary orifice subcircular with weakly defined poster. Peristome well developed with thickly calcified rim. Ooecia small, globular, with peripheral band of tiny pores, opening into peristome. No avicularia.
Remarks.
Canu & Bassler (1928a) placed their new Western Atlantic species
Lagenipora verrucosa
in the
Phylactellidae
, although
Lagenipora
Hincks, 1877
is a celleporid (see Hayward & Ryland 1999: 332), with
Cellepora lepralioides
Norman, 1868
the
type
species. Cheetham & Sandberg (1964) created the genus
Lagenicella
,
type
species
Lagenipora marginata
, Canu & Bassler, 1930
, for eight species previously attrbuted to
Lagenipora
, but did not include
Lagenipora verrucosa
in this group, which they also placed in the
Phylactellidae
.
Perhaps Hincks’ (1877) definition of
Lagenipora
could be modified to include
L. verrucosa
, which does appear to be celleporid in affinity. Like
Lagenipora
, the primary orifice is rounded with indistinct condyle and no orificial spines, the peristome is well developed and conceals the primary orifice rapidly as zooids develop, and the ooecium is hyperstomial and opens into the base of the peristome distally. The entooecium is distinctively perforated by a peripheral band of minute pores. There are no avicularia.
However,
L.
verrucosa, in addition to being uniserial and branching, lacks the large kenozooids mentioned by Hayward & Ryland (
1999
, p.
532
).
It also has open-ended tubercles (i.e. tubiform pores) in the frontal shield in addition to the few marginal pores and the minute entooecial pores
.
For these reasons a new genus is created for
L. verrucosa
.
