Remarks.
SPAETH (1902)
described
Ctenochira tristicula
as a distinct species similar only to
Microctenochira quadrata
due to similarly shaped and deeply impressed clypeus. Later on,
SPAETH (1919)
studied the
type
of
Coptocycla conspersa
and found it is conspecific with
C. tristicula
.
SPAETH (1926)
revised Neotropical species of the tribe
Cassidini
with pectinate tarsal claws and synonymized
C. conspersa
with
Ctenochira semilunaris
. Since then the latter name is used as valid for this species. I have studied
types
of all abovementioned nominal taxa with the exception of
C. conspersa
and found that they are conspecific with
Coptocycla usta
. Hence, I transfer the latter species to
Microctenochira
and synonymize with it
M. semilunaris
, including all the taxa previously considered as its synonyms.
