Abstract: 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.

Multiple lines of evidence provided support for the monophyly of the subfamily Neanurinae. Nevertheless, relationships among and within its tribes are largely unknown. The tribe Neanurini, being the second largest within Neanurinae, comprises over 170 species belonging to 29 genera, distributed in the northern hemisphere only, except two species that have been distributed worldwide presumably by human activities. A cladistic analysis of the tribe was reconstructed based on 68 morphological characters. The ingroup comprises 39 species, representing extant genera of Neanurini, including monotypic genera, while outgroups include 5 species of each known tribe according to Cassagnau’s tribal classification. Both equal- and implied-weighting parsimony analyses were used in phylogenetic reconstruction. The cladistic analyses were based on a comprehensive survey of adult morphological characters because specimens suitable for molecular studies were not available for most taxa. The phylogenetic analysis resulted in the recognition of the tribe Neanurini as non-monophyletic because three of the five outgroups nested within the members of Neanurini. The genera Caucasanura, Catalanura, Endonura, Kalanura, Neanura, Protanura and Pumilinura were recovered as paraphyletic. The genera of Neanurini were subdivided into five clades. Their monophyly and phylogenetic relationships are thoroughly discussed. This phylogeny constitutes a new framework for studying the internal relationships of the tribe Neanurini and the subfamily Neanurinae.

Honduranura gen. n. and the type species H. centraliamericana sp. n. are described and illustrated. The new genus shows the characters of Sensillanurini Cassagnau, 1983 tribe and is distinguished by the fusion of cephalic and abdominal tubercles: clypeal with antennofrontal and dorsointernal with dorsoexternal on head; presence of fused tubercles on each side of abdominal segment V. Most of the tubercles bear strong subcuticular reticulation. A key for the genera of the tribe Sensillanurini is provided.
