Himerometroidea is a clade of chiefly shallow-water, tropical, feather-star crinoids that is currently divided, based on morphology, into four families comprising 119 extant species in 31 genera. Our molecular phylogenetic results, based on three mitochondrial (CO1, 16S, CytB) and two nuclear (ITS and 28S) markers for 55 accepted species in 23 of the extant genera, allow for six clades within Himerometroidea to be given family ranks. Maximum parsimony, maximum likelihood, and Bayesian inference analyses recovered largely congruent topologies with varying nodal support. A new classification revises generic placements among five families: Himerometridae, Colobometridae, and Mariametridae, all retained, and Pontiometridae and …
Extant Crinoidea (Echinodermata) Of Singapore, Charles Messing, Teresa S. Tay
Extant Crinoidea (Echinodermata) Of Singapore, Charles Messing, Teresa S. Tay

The crinoid fauna of Singaporean waters now includes approximately 39 nominal species belonging to six families, all in Order Comatulida. Seventeen of the 22 species collected during the Singapore Strait Biodiversity Workshop (May-June 2013) were previously known from the area. Of the remaining five, Cenometra bella (Colobometridae) is definitely a new record for Singapore, while the taxonomic status of the other four is uncertain. Seventeen additional species, collected almost entirely in the nineteenth and early twentieth centuries, were not represented in the 2013 survey.
Case 3270: Isometrinae Clark, 1917 (Ecinodermata, Crinoidea): Proposed Emendation Of Spelling To Isometrainae To Remove Homonymy With Isometrinae Kraepelin, 1891 (Arachnida, Scorpiones), Victor Fet, Charles G. Messing

The purpose of this application, under Articles 55 and 29 of the Code, is to remove the homonymy between the crinoid subfamily name ISOMETRINAE Clark, 1917 (type genus Isometra Clark, 1908; family ANTEDONIDAE) and the scorpion subfamily name ISOMETRINAE Kraepelin, 1891 (type genus Isometrus Ehrenberg in Hemprich & Ehrenberg, 1828; family BUTHIDAE). It is proposed that the entire generic name of Isometra should be adopted as the stem, so that the correct spelling of the crinoid subfamily will become ISOMETRAINAE Clark, 1917.

Recent collections of crinoids from the intertidal zone to 1,650 m in the tropical western Atlantic have provided significant range extensions for more than half of the 44 comatulid and stalked species known from the region. Of the 34 comatulid species, over 60% are endemic to the region; of the 10 stalked species, 90% are endemic. At the familial level, this fauna has its strongest affinities with the tropical Indo-Pacific region. Comatulids are most abundant above 300 m, while stalked species occur primarily between 100 and 700 m. Species that occur primarily above 600 m (the deepest penetration of the …

A Revision Of The Comatulid Genus Comactinia A. H. Clark (Crinoidea: Echinodermata), Charles G. Messing
Marine & Environmental Sciences Faculty Articles
The formerly monotypic genus Comactinia is found to comprise two valid species. One of these is further divided into two subspecies. The variability of the genus is examined and illustrated. A discussion of ecology, affinities, and zoogeography is included.
