“…Whenever possible, all features were assessed in one to five specimens of each species. Further details can be found in Cassagnau (1983a,b); Cassagnau and Palacios‐Vargas (1983); Palacios‐Vargas (1984, 1986, 1996); Vázquez and Palacios‐Vargas (2005).…”

In order to assess the phylogenetic structure of the springtail genus Palmanura, as well as to test the monophyly of the tribe Sensillanurini (Neanuridae: Neanurinae), a data matrix of morphological (chaetotactic and other) characters of members of this group was assembled and analysed in the light of Wagner parsimony. The data matrix included all the known members of the Neotropical genus Palmanura, plus representatives of Sensillanura and Americanura. Although not all the clades obtained were highly supported by bootstrap resampling, some structures were relatively constant under different approaches. Alternative analyses (unordered and ordered character states, rescaled weighting procedure) were applied. While alternative solutions were obtained, a number of structures were shared by the results irrespective of the method used. On this basis, the results suggest that some further reassessment is required to confirm formally the monophyly of the tribe Sensillanurini. The genera Palmanura and Americanura are mutually poly ⁄ paraphyletic; we thus suggest that Palmanura should be considered as a synonym of Americanura, although some character reassessment and more varied outgroup species may be necessary before a formal generic redefinition can be proposed. Finally, a comparison of the performance of the characters under Wagner parsimony analysis indicated that differences in the charactersÕ retention indexes are due not to the topological (tagmal) position of the traits involved, but to character coding: the characters describing quantitative features (generally numbers of setae) generally performed worse than other types of characters under parsimony. An updated list of the known members of the Sensillanurini (Collembola: Neanuridae: Neanurinae) is presented.

Tabasconura gen. nov. (Neanuridae) and type species T. tapijulapana sp. nov., are described and illustrated. The new genus possesses all characters of the tribe Sensillanurini Cassagnau, and is characterised by the presence of slightly elongated tubercles on the body and also elongation and thickening of the sensillum S2 as well as S7 on antennal segment IV. Development of S7 is a character of the tribe.
