Resumen:
The Neotropical species of Asthenopodinae are revised in a formal phylogenetic context. The five known
species of Asthenopus Eaton, 1871, together with other five new species were included in a cladistic analysis
using morphological characters (continuous and discretes). Representatives of the Afro-Oriental group
of the subfamily (Povilla Navás, 1912 and Languidipes Hubbard, 1984) were also included to test the
monophyletic hypothesis traditionally accepted for the group. Additional taxa representing the other
subfamilies of Polymitarcyidae were incorparated: Ephoron Williamson, 1802 (Polymitarcyinae) and
Campsurus Eaton, 1868, Tortopus Needham & Murphy, 1924 and Tortopsis Molineri, 2010 (Campsurinae).
A matrix of 17 taxa and 72 characters was analyzed under parsimony resulting in a single tree supporting
the monophyly of the subfamily Asthenopodinae. Other results include the monophyly of the Afro-
Oriental taxa (Povilla and Languidipes), the paraphyletic nature of Neotropical Asthenopodinae, and the
recognition of four South American genera: Asthenopus (including A. curtus (Hagen), 1861, A. angelae de
Souza & Molineri, 2012, A. magnus sp. n., A. hubbardi sp. n., A. guarani sp. n.), Asthenopodes Ulmer, 1924,
stat. n. (including A. picteti Hubbard, 1975, stat. n., A. traverae sp. n., A. chumuco sp. n.), Priasthenopus
gen. n. (including P. gilliesi (Domínguez), 1988, comb. n.), and Hubbardipes gen. n. (including H.
crenulatus (Molineri et al.), 2011, comb. n.). Descriptions, diagnoses, illustrations and keys are presented for all Neotropical taxa of Asthenopodinae (adults of both sexes, eggs and nymphs). Additionally a key
to the subfamilies and genera of Polymitarcyidae is included. A quantitative biogeographic analysis of
vicariance is presented and discussed through the study of the ?taxon history? of the group.
