The new genus is unusual among Uropodina by the presence of an internal sclerotised node associated with the levator tendon in large, strongly dentate chelicerae. Taxonomic notes on the genus Hutufeideria are presented and three new species are described (Hutufeideria thailandica sp. nov., Hutufeideria phuketensis sp. nov., Hutufeideria alata sp. nov.). The name of the Australian species Hutufeideria hirschmanni (Hiramatsu, 1978) is a homonym of Hutufeideria hirschmanni Hiramatsu, 1978, from New Guinean, hence Hutufeideria hirschmannoides nom. nov. is proposed as a replacement name for the Australian species.

According to them (p. 1032) "Molecular sequence data have greatly increased our ability to identify homoplastic traits." This is made clear, for example, in their flow chart for homoplasy detection (Figure 2, p. 1034), wherein homoplasy is discovered through the mapping of "traits of interest" onto a phylogram, a practice common in the molecular phylogenetic paradigm. The "mapping" is usually of morphological characters that are employed to support the chosen (molecular) topology, but which, as a consequence, do not themselves contribute to the formation of those topologies (Assis & Carvalho 2010).
