Subgenus Antiperyphanes Jeannel, 1962

Antiperyphanes Jeannel, 1962; type species Bembidium spinolai Solier, by original designation.

Plocamoperyphus Jeannel, 1962; type species Bembidium mandibulare Solier, by original designation. New synonymy.

Remarks.

This group contains at least 19 described species ( Toledano 2002; Toledano 2008), and is characterized by males having an aedeagus lacking a brush sclerite, and with a very long flagellum ( Maddison et al. 2013; Toledano 2008).

Included here are some species previously placed in subgenus Antiperyphus by Jeannel (1962): Bembidion hirtipes (Jeannel), Bembidion ringueleti (Jeannel), Bembidion rufoplagiatum Germain, Bembidion uniforme Csiki, and Bembidion parvum (Jeannel). Bembidium mandibulare Solier belongs to Antiperyphanes as well, and is nested well within it (Fig. 8); thus, subgenus Plocamoperyphus is a synonym of Antiperyphanes . There are no morphological characteristics of Bembidium mandibulare that would suggest it is not a member of Antiperyphanes ; it shares all apomorphies of the group. As first reviser, I choose Antiperyphanes as the valid name of the group.

Antiperyphanes has two distinct clades, each very well supported: the Bembidion caoduroi group (clade j in Fig. 8; Fig. 1D), consisting (among the sampled species) of three large species from the northern Andes (Fig. 1D); (2) the remaining Antiperypanes (clade k in Fig. 8; Figs 1 A–C, E). Each is supported by MLB=100 and PB=100 in the multi-gene analyses, and individually by support from five to seven genes (Table 3). As a whole, however, the monophyly of Antiperyphanes is only weakly supported by the combined analysis and analyses of four genes (Table 3).

Members of this subgenus are found at the edges of bodies of water. For example, Bembidion rufoplagiatum and Bembidion zanettii are common on gravel and cobble river shores, Bembidion ringueleti is found on gravel and sand shores of smaller creeks, and Bembidium mandibulare on the sand beaches of the Pacific Ocean in Chile and sand beaches of rivers in Argentina.
