Summary description
(from
Calcinai
et al.
2013
). Thinly encrusting on soft coral, red in life, soft, with optically smooth surface. Ectosomal skeleton a reticulation of spicular tracts with 4–5 spicules in cross section. Choanosomal skeleton of thin ascending spicule tracts. Spicules mycalostyles with elongate heads, 240–280 x
5–10 µm
, anisochelae I of
42.5–50 µm
, arranged in rosettes, anisochelae II
22.5–27.5 µm
, anisochelae III
12.5–17 µm
, sigmas in two size categories, 92.5–117.5 x
5–11.5 µm
and
17.5–27.5 µm
, toxas
17.5–380 µm
, micracanthoxeas
5–10 µm
.
Distribution
. Oahu,
Hawaii
Islands,
0.5–3 m
depth.
Comments
. The two specimens from
Hawaii
named
Mycale (Aegogropila)
cf.
lilianae
by
Calcinai
et al.
2013
are probably not conspecific with the
Carballo & Hajdu’s (1998)
species. Color of the Brazilian species was yelloworange, not red. The spicule complement is quite similar, although toxas are smaller in the Brazilian species, but with exception of the micracantoxeas that complement is also similar to that of
Mycale (Ae.) orientalis
(cf. above), making the similarity not a significant reason to consider the
Hawaii
material conspecific.
De Laubenfels (1951)
described
Carmia contarenii
(Lieberk̹hn, 1859) from
Hawaii
(here reassigned to
Mycale (Ae.) orientalis
,
cf. above), which could also turn out to be this species if we assume that the micracanthoxeas could have been overlooked (they are only reliably identified under SEM). We refrain from proposing a new name for Calcinai
et al.
’s
Hawaii
material, but suggest that it is likely a species new to science.
