Review of part of Hispaniolan Annulariidae

The third post on Watters’ 2016 papers concerns his review of the Paracondria (Chondropomorus) complex. “Nineteen species are recognized including eight new species: Parachondria anatolensis n. sp., Parachondria arcisensis n. sp., Parachondria daedalus n. sp., Para- chondria heatheraikenae n. sp., Parachondria isabellinus n. sp., Parachondria muchai n. sp., Parachondria silvaticus n. sp., and Parachondria stigmosus n. sp. Distributional and habitat notes are given for additional taxa. Chondropoma marinum “Weinland” Reeve, 1863, is regarded as a nomen dubium. Chondropoma (Chondropomorus) moroni Bartsch, 1946, is reidentified as Crossepoma emilianum (Weinland, 1862). Chondropoma simplex Pfeiffer, 1852, regarded by Bartsch (1946) as a Chondropomorus, is considered a Chondropoma”.

New Annulariidae from Hispaniola

Today two papers by Thomas Watters describing new species from the island of Hispaniola. Watters’ (2016a) abstract is “Chondropoma bellavittatum new species is described for the Haitian species referred to by Bartsch, 1946, as Chondropoma semilabre Lamarck, 1822. This latter species is shown to be a different taxon from the Bahamas”.

The second paper, which appeared in the same journal, deals with a new species from the eastern part of the island. “Parachondria joyeuse is described from the eastern Dominican Republic. The new species is characterized by a thin, high- spired, nearly smooth shell and a peculiar color pattern. It is placed in Parachondria with reservation”.

New Annulariidae from Dominican Republic

Thomas Watters has published last year a series of papers on Antillean Annulariidae which have not been mentioned here. Today I start with a paper on the Dominican Republic; the abstract reads “A new genus and species of Annulariidae are described from the Dominican Republic: Tessaripoma n. gen. and Tessaripoma arenarium n. sp. The genus also contains T. hooksi (Watters & Duffy, 2010) and T. alyshae (Watters & Duffy, 2010). The genus is endemic to the eastern end of the Hoya de Enriquillo between the Tiburon/Barahona Peninsula and the remainder of Hispaniola”.

A new Tudora from Venezuela

In the most recent number of Basteria Hovestadt published a short paper on the Peninsula de Paraguaná in Venezuela, describing a new Annulariid species: Tudora paraguanensis. The new species is the first record of Tudora from the South American mainland, and although the collected specimens are regarded as ‘subfossil’, it cannot be excluded that the finding of living specimens is possible.

Field observations on Curacao

Just appeared: a paper by Gerard van Buurt with field observations and new records on the malacofauna of Curacao. Especially the ecological observations are very interesting and a new hypothesis is formulated which may explain the disjunct distribution of Drymaeus elongatus on the island.

Buurt2016_1

The abstract reads: “Currently 31 species of terrestrial snails are known from Curaçao, 28 of these are indigenous. The taxonomy of Curaçao land snails has been studied quite well. An inventory of species and subspecies exists. About their ecology however much less is known. The influence of salt spray from the sea on the distribution of some species is discussed. By observing snails in the field some conclusions about their ecology have been reached; these and some further assumptions are hereby presented. Three of the larger species of indigenous snails are discussed. These are Cerion uva, Drymaeus elongatus and Tudora megacheilos. The introduced snails Bulimulus guadalupensis, Zachrysia provisoria and Achatina fulica (= Lissachatina fulica) are briefly mentioned; the latter two are new records for Curaçao”.

Annulariidae from Hispaniola

Thomas Watters is known for his thorough papers on Annulariidae. A new one was just published, this time about species from Hispaniola. The species complex of Abbottella morelatiana is reviewed and A. cretaegus sp.n. is described.

Watters2016Abbottellinae

The genus Abbottella, Leiabbottella, Lagopoma, and Rolleia are placed in the new subfamily Abbottellinae.
