Characters of Phoeniciloricus and Culexiregiloricus are based on descriptions of the postlarval stage as adult stages are not known for these two genera. The nanaloricid
genus Australoricus is not included in this table because neither the postlarval nor the adult stages are known for this genus (i.e., its description is based solely on the
larval stage).
� Characters from Nanaloricus khaitatus were not taken into account in this comparative table because the original description of the species is probably based on
observations of at least three different species.

b Concerning only the anteriormost groups of flosculi.
