G. Thomas Watters recently had two papers out on Annulariidae. The first one (2014a) is a “preliminary review” of the Lesser Antillean species. The brief abstract reads “The Annulariidae of the Lesser Antilles, including the Virgin Islands, Isla de Vieques, and Isla Culebra, are reviewed. Eleven species are recognized in three genera. With rare exceptions, all occur in the Limestone Caribbees. One species, Parachondria basicarinatus (Pfeiffer, 1855), from St. Croix, may be extinct. All are believed to be related to Puerto Rican taxa.”
The following species are recognised: Chondropoma (Chondropoma) julieni Pfeiffer, 1866; Chondropoma (Chondropoma) pupiforme (Sowerby, 1843); Chondropoma (Chondropoma) rufilabre (Potiez & Michaud, 1838); Parachondria (Parachondria) basicarinatus (Pfeiffer, 1855); Parachondria (Parachondria) lineolatus (Lamarck, 1822); Parachondria (Parachondria) santacruzensis (Pfeiffer, 1855); Diplopoma (Diplopoma) crenulatum (Potiez & Michaud, 1838); Diplopoma (Diplopoma) decussatum (Lamarck, 1822); Diplopoma (Diplopoma) sulculosum (Pfeiffer, 1852).
The second paper (2014b) presents a revision of the Central American taxa of the family. “Twenty annulariid taxa are reviewed from Central America, including three new species and one new genus. One species is regarded as an incertae sedis and two as mislabeled lots of Cuban origin. Many species are highly endemic. Although not speciose, Central America has a high diversity of conchological forms and may represent the ancestral source of annulariids
in general.” A key to the genera is also presented.
The following taxa are recognised c.q. described: Choanopomops largillierti (Pfeiffer, 1846); Halotudora gaigei (Bequaert & Clench, 1931); Halotudora gruneri (Pfeiffer, 1846); Halotudora kuesteri (Pfeiffer, 1852); Gouldipoma chiapasense (Crosse & Fischer, 1877); Gouldipoma sumichrasti (Crosse & Fischer, 1874); Gouldipoma coltrorum new species; Gouldipoma terecostatum (Thompson, 1966); Gouldipoma callipeplum (Solem, 1961); Gouldipoma chrysostiria new species; Gouldipoma thomasi (Solem, 1961); Gouldipoma trochleare (Pfeiffer, 1852); Tudorisca andrewsae (Ancey, 1886); Paradoxipoma new genus; Paradoxipoma enigmaticum new species; Diplopoma osberti (Tristram, 1861); Diplopoma rigidulum (Morelet, 1851); Parachondria cordovanus (Pfeiffer, 1857); Parachondria cordovanus (Pfeiffer, 1857); “Choanopoma” cygni Pilsbry, 1930.
For all of these taxa data are given about type material, synonymy, material seen and distribution, habitat and conservation status, (re-)description, variation, comparison with other taxa, original description (translated), etymology.
These two very thorough papers are new hallmarks for this group of snails.
