Notes.
This was a new name given by
Pont (1980)
to
H. maculipennis
Emden, 1941
, a junior secondary homonym of
Helina maculipennis
(
Zetterstedt, 1845
). It was originally described in
Anthocoena
Emden, 1941
, a genus of the “
Anthomyiinae
” (see also
Emden 1951
), because of the “almost complete sixth vein”.
