The chiefly tropical, deep-water (>100 m) feather star family Charitometridae (Echinodermata: Crinoidea: Comatulida) currently consists of 34 species in eight genera and has not been revised since 1950. Recent molecular analyses and the discovery of both new specimens of known species and a new species prompted a morphological re-examination of those genera with abruptly expanded genital pinnules. As a result, Poecilometra is redescribed, and now includes four species, including two formerly placed in Strotometra, plus Poecilometra baumilleri n. sp Poecilometra scalaris is placed in synonymy under P. acoela. Strotometra is redescribed and S. hepburniana placed in synonymy under S. parvipinna. The diagnoses of both genera and their component species are revised.
