Antiperyphanes Complex

Remarks.

Members of the Antiperyphanes Complex are diverse in form (Figs 1-3, 5). There are no recognized derived morphological characteristics of the group, although the clade is moderately well supported by the concatenated DNA sequence data (Fig. 8, Table 3). Within the South American fauna, most species can be recognized by the lack of an N sclerite in the internal sac of the male genitalia ( Toledano 2008). However, some members of the complex, including some species in subgenus Nothonepha , have a small sclerite that could be homologous to the N sclerite ( Toledano 2008).

The Antiperyphanes Complex, as here classified, consists of at least five subgenera: Antiperyphanes , Chilioperyphus , Antiperyphus , Notholopha , Ecuadion , and Nothonepha . Each of these subgenera is briefly discussed below, with notes about their composition. Two other poorly known subgenera, Pseudotrepanes Jeannel and Notoperyphus Bonniard de Saludo, are likely members of this complex, but specimens will need to be examined to confirm their membership.
