Remarks.
In his original descriptions,
Huckett (1966)
relied on subtle differences in variable characters to separate
D. rivalis
from
D. amnicola
. Following the examination of
type
material from these two taxa we concluded that all features listed in the original descriptions are variable (including the pollinosity of the female parafacial, a feature we found to vary from entirely dusted to mostly glossy in the
type
series of
D. amnicola
), and that
D. rivalis
is a synonym of
D. amnicola
.
Furthermore,
Huckett (1966
,
1975
) uses the strength of
av
bristles on the apical 1/2 of F2 to separate males
D. santamonicae
(strong and long) from
D. amnicola
(weak) and junior synonym
D. rivalis
(weak but slightly stronger). While the male
holotypes
of these taxa do exhibit a difference in the strength of the F2
av
, we have found this feature to be variable. The configuration of the F2
pv
row and the pollinosity of the thorax and abdomen appear to be more stable characters to separate the males of
D. santamonicae
from those of
D. amnicola
(and the similar
D. aldrichi
) (see couplet 21 of male key).
