This genus is
systematically complex and sometimes controversial. One reason that the genus is complex is because of the species' variable
karyotypes:
*Note that
R. tumida is listed four times, as individuals have been found with four different
karyotypes. This may represent a
species complex. However, others argue that as Allen's yellow bat and the
slender yellow bat are
sister taxa, to exclude only one from
Rhogeessa makes it a
paraphyletic group. By that logic, either both species need to be included in
Rhogeessa, or both need to be placed in
Baeodon. ==References==
