Genus
Trophogemma
Jankowski, 1970
Improved diagnosis.
Suctorian ciliates with large, laterally flattened cell body, attaching to the host body surface by a stalk. Two actinophores (cell body protuberances) placed near the base of the body, and a tentacle fascicle at the top. A few tentacle fascicles located at several levels or several tentacles evenly distributed along the margin of the body. Lateral tentacles can be absent. Macronucleus band-like but not branched. Micronuclei small and numerous. Reproduction by vermigemmy with worm-like, unciliate swarmers. Commensal species of marine crustaceans.
Type species.
Trophogemma poljanskyi
Jankowski, 1970
Remarks.
Jankowski (1970)
observed that the closest species of
Trophogemma poljanskyi
is
Rhabdophrya wailesi
Kahl, 1934
, but proposed the allocation of the two species in separate genera due to the smaller length of the stalk of
T. poljanskyi
. However, the degree of development of the stalk structure appears not to be a character significant enough to erect a new genus as suggested by
Dovgal (2002)
. In addition, actinophores are absent in representatives of the genus
Rhabdophrya
Chatton et Collin, 1910
, whereas two basal actinophores like those in
Trophogemma
are present in
R. wailesi
. Thus, we propose to transfer
Rhabdophrya wailesi
into the genus
Trophogemma
as
Trophogemma wailesi
(Kahl, 1934)
