Taxon classification Animalia Coleoptera Carabidae
Subgenus
Antiperyphus Jeannel, 1962
Antiperyphus
Jeannel, 1962; type species
Bembidium philippii
Germain, by original designation.
Remarks.
As noted by
Toledano (2008)
,
Jeannel's
concept of
Antiperyphus
was polyphyletic, with at least
Bembidion hirtipes
,
Bembidion ringueleti
,
Bembidion rufoplagiatum
, and
Bembidion uniforme
Csiki belonging within
Antiperyphanes
. This is confirmed in part by my results (Fig. 8, Table 3). In addition,
Bembidion engelhardti
,
Bembidion eburneonigrum
,
Bembidion tucumanum
, and
Bembidion germainianum
are members of
Nothonepha
, not
Antiperyphus
. Of the species included in the subgenus by
Jeannel (1962)
, this leaves only the type species,
Bembidium philippii
(Fig. 2A).
In addition,
Bembidion peterseni
Jensen-Haarup (1910)
, from Mendoza, Argentina, can tentatively be placed here. I have examined a male syntype (in ZMUC), and it is similar in appearance to
Bembidium philippii
, although with much deeper and longer elytral striae. It is not a member of
Nothonepha
(as it lacks mesepisternal pits), nor is it a member of
Antiperyphanes
(it has a brush sclerite, and does not have the long flagellum characteristic of
Antiperyphanes
). The internal sac of the male genitalia, although difficult to see because of the nature of the preparation, appears very similar to that of
Bembidium philippii
.
B. philippii is common on sand shores of rivers in the provinces of
Neuquen
and Chubut in Argentina; it also occurs in Chile.
