Thelidomus aspera is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusc in the family Pleurodontidae. It is endemic to Jamaica.Rosenberg G. & Muratov I. V. 11 August 2005. RECENT TERRESTRIAL MOLLUSKS OF JAMAICA.
Invasive species This species has not yet become established in the US, but it is considered to represent a potentially serious threat as a pest, an invasive species which could negatively affect agriculture, natural ecosystems, human health or commerce. Therefore, it has been suggested that this species be given top national quarantine significance in the USA.Cowie R. H., Dillon R. T., Robinson D. G. & Smith J. W. (2009). "Alien non-marine snails and slugs of priority quarantine importance in the United States: A preliminary risk assessment". American Malacological Bulletin 27: 113-132. PDF .
Ecology Parasites Thelidomus aspera is a host for larvae of the parasites Angiostrongylus cantonensis and Aelurostrongylus abstrusus.Lindo J. F., Waugh C., Hall J., Cunningham-Myrie C., Ashley D., Eberhard M. L., Sullivan J. J., Bishop H. S., Robinson D. G., Holtz T. & Robinson R. D. (2002).
