The validity of genera and species in the Capsalinae
and Trochopodinae are now most in need of extensive
reappraisal ,these two large subfamilies each comprise
approximately 50 species and together account for
more than 50% of all described capsalid taxa. Egorova
(1989) and LamotheArgumedo (1997) disagree about
the number of capsaline genera which impacts on the
composition of other genera. The Trochopodinae,
almost exclusively parasites from gills of perciform
teleosts, are perhaps the most morphologically diverse
subfamily with regard to: number of haptoral loculi;
arrangement of anterior attachment apparatus;
number of testes (two arranged either juxtaposed
Megalocotyloides or in tandem Macrophyllida four
Trilobiodiscus or multiple in two groups.
Sprostoniella
Egorova 1994. The large number of
genera containing few species reflects morphological
diversity in trochopodines: all but three of the 17
genera contain only one to three species
Diagnostic characters of this genus are the two
neighboring groups of testes, and the structure of
loculi of the haptor. These characters were confirmed
by Ergorova (1994) in her revision of Trochopodinae.
The Genus consist of three species of
Sprostoniella
,
S.
lamothei
Pérez-Ponce de Léon & Mendoza-Garfias,
2000;
S. multitestis
Bychowsky & Nagibina, 1967;
S.
micrancyra
Cezar, Luque y Amato, 1999.
Bychowsky & Nagibina (1967) established
Sprostoniella
with the type species
S
.
multitestis
parasitic on
Platax
pinnatus
(L.).
Sprostoniella micrancyra
as described
as new species are differ from
S. multitestis
by the
arrangement of septa (with 17 septa, two of them bifid
and two incomplet whereas 17 septa, two of them
trifid in
S. multitestis
. Moreover,
Sprostoniella
micrancyra
showed two central loculi, while
S.
multitestis
only one, in
Sprostoniella micrancyra the
first pair of anchors is small and poorly developed,
while in
S. multitestis
is well developed and strong
(Cezar et.al, 1999).
The specimens described in this study differ from the
two types above by the fallowing: 11 septa; not bifid,
incomplete and central locale absent, one pairs of
anchors; Testes, in two groups, each group with 9
testes. So we consider this as a new species and
Platax
teira
represents a new host and new geographical dist.
