Comments:
Apiochaeta mallochi
most closely resembles
A. excepta
and
A. lenticula
,
but unlike
A. excepta
, tergite 1 is yellow, the lateral scutellar bristles are stronger than the apical bristles, and the male genitalia resemble those of
A. lenticula
. Compared to
A. lenticula
,
A. mallochi
is smaller, darker, there are no stripes behind the female head and male tergite 7 is smaller and more poorly-developed.
