Taxonomic remark The hydroid of Clytia brevithecata (Thornely, 1900), type locality Papua New Guinea, appears
indistinguishable morphologically from that of Clytia hummelincki (Leloup, 1935), type locality Bonaire, in the
Caribbean Sea. Both have very shallow, cup-shaped hydrothecae with an entire margin, a subhydrothecal spherule,
and unbranched pedicels with annulations at the base and occasionally elsewhere. Their gonothecae also seem indistinguishable.
Connections between Indo-Pacific and Atlantic populations appear to exist, given Millard’s (1966a,
1975) record of C. hummelincki from Agulhas Bank at the southern tip of Africa. Based on morphology, the two are
taken to be conspecific, with the name C. brevithecata having nomenclatural priority. Galea & Ferry (2015:
241) had suggested earlier that the two might be conspecific. [details]

Taxonomic remark The nominal species
C. hummelincki is, very likely, nothing more than a junior
synonym of Campanularia brevithecata Thornely, 1900.
Colonies of the latter form simple, unbranched stems,
annulated basally and occasionally elsewhere, and are
provided distally with a characteristic spherule below a
very shallow hydrotheca. All these are features met with
in Leloup’s species. In addition, nothing distinguishes
the shape of the gonotheca illustrated by Thornely from
those examined by Millard (1975) in her material from
the Indian Ocean assigned to C. hummelincki. Moreover,
the presence in each gonotheca of C. brevithecata of one
or two gonophores with four radial canals (there is no
mention of discernible gonads), is in conformity with
several convergent observations on C. hummelincki
(Millard, 1975; Gravili et al., 2008; present study). It is
obvious that the occurrence of a subhydrothecal spherule
and the lack of knowledge of the nature of the gonophores
mislead Thornely with respect to the genus in which she
included her new species. [details]

Taxonomic remark The hydroid of Clytia brevithecata (Thornely, 1900), type locality Papua New Guinea, appearsindistinguishable morphologically from that of Clytia hummelincki (Leloup, 1935), type locality Bonaire, in the
Caribbean Sea. Both have very shallow, cup-shaped hydrothecae with an entire margin, a subhydrothecal spherule,
and unbranched pedicels with annulations at the base and occasionally elsewhere. Their gonothecae also seem indistinguishable.
Connections between Indo-Pacific and Atlantic populations appear to exist, given Millard’s (1966a,
1975) record of C. hummelincki from Agulhas Bank at the southern tip of Africa. Based on morphology, the two are
taken to be conspecific, with the name C. brevithecata having nomenclatural priority. Galea & Ferry (2015:
241) had suggested earlier that the two might be conspecific. [details]
Taxonomic remark The nominal species
C. hummelincki is, very likely, nothing more than a junior
synonym of Campanularia brevithecata Thornely, 1900.
Colonies of the latter form simple, unbranched stems,
annulated basally and occasionally elsewhere, and are
provided distally with a characteristic spherule below a
very shallow hydrotheca. All these are features met with
in Leloup’s species. In addition, nothing distinguishes
the shape of the gonotheca illustrated by Thornely from
those examined by Millard (1975) in her material from
the Indian Ocean assigned to C. hummelincki. Moreover,
the presence in each gonotheca of C. brevithecata of one
or two gonophores with four radial canals (there is no
mention of discernible gonads), is in conformity with
several convergent observations on C. hummelincki
(Millard, 1975; Gravili et al., 2008; present study). It is
obvious that the occurrence of a subhydrothecal spherule
and the lack of knowledge of the nature of the gonophores
mislead Thornely with respect to the genus in which she
included her new species. [details]
