Taxonomy The validity of Falcaustra Lane, 1914, has been in question
almost since its proposal. This genus has often been considered
a synonym of Spironoura Leidy, 1856. Spironoura as
originally constituted contained 2 species, both briefly described
(Leidy, 1856), Spironoura gracile, type species, from
the stomach of Pseudemys floridana (5Emys serrata) and Spironoura
affine from the large intestine of Terrapene carolina
(5Cistodo carolina). Boulenger (1923) subsequently found S.
affine in T. carolina and redescribed it as Falcaustra chapini.
Chapin (1924) suggested that because F. chapini Boulenger,
1923, was based on 1 of the 2 species originally included in
Spironoura, Falcaustra should become a synonym. Yorke and
Maplestone (1926) agreed and in their compilation all species
originally assigned to Falcaustra were moved to Spironoura;
in addition, Spirura Diesing, 1861, Florencioia Travassos,
1919, and Spectatus Travassos, 1923 were listed as synonyms
of Spironoura. However, Harwood (1932) thought that because
S. gracile was the type and had not been studied, it
would be premature to consider Falcaustra as a synonym of
Spironoura. Freitas and Lent (1941) considered S. gracile a
nomen nudum and proposed the revalidation of Falcaustra
Lane, 1914 and Spectatus Travassos, 1923; all species assigned
to Spironoura were reassigned to Falcaustra with Falcaustra
falcata as type species. Skryabin et al. (1951) did not
accept these assignments and reassigned all species of Falcaustra
to Spironoura. Chabaud and Brygoo (1957) accepted
the assignments of Freitas and Lent (1941) but added Dibulbiger
Caballero, 1935 and Zanclophorus Baylis and Daubney,
1922 as synonyms of Falcaustra. Yamaguti (1961) rejected
these assignments and reestablished Spironoura. However,
Baker (1987) returned to Falcaustra, pointing out that Walton
(1927) in his revision of the Leidy collection showed that the
type species was probably not congeneric with Falcaustra.
Leidy (1856) described the esophagus of Spironoura as pestleform;
the esophagus of Falcaustra is usually described as having
an hourglass-shaped bulb or a spherical isthmus preceding
the bulb. It is perhaps best to continue Baker’s (1987) reasoning
that because the original description of Spironoura is so
inadequate it should be regarded [details]
