The genus Woitkowskia was described by Enzmann (1952) for two neotropical species. It was synonymized by Borgmeier (1955) with Neivamyrmex  HNS  and its type species, W. connectens Enzmann  HNS  , synonymized with N. walkerii (Westwood, 1842)  HNS  ; the status of W. mexicana Enzmann  HNS  , 1952, was left unresolved. As the name implies, W. mexicana  HNS  was described from a single male from Tuxtla Gutierrez, Chiapas, Mexico; the present location of the type is unknown. Despite its verbosity the original description is mostly worthless and the accompanying figures are inept. It is not surprising that subsequent workers have largely avoided dealing with this taxon. Watkins, in his several papers on North American Neivamyrmex  HNS  ignored this species altogether. Bolton (1995) merely noted that Enzmann's name was an unresolved junior seconday homonym of N. mexicanus (F. Smith, 1859)  HNS  .

Worthless as Enzmann's description and figure of W. mexicana  HNS  appear to be, it is possible to match them to males of N. halidaii  HNS  , a species that is common at the type locality of W. mexicana  HNS  . Accordingly we have synonymized that name here because there appears to be no reason not to do so. Unless the type is some day located and proven not to be a synonym of N. hallidaii  HNS  , this seems the best way to deal with Enzmann's name.
