testâ compressè ovatâ, ventricosissimâ, vix umbilicatâ, spirâ parvâ, subimmersâ, anfractibus ad suturam impressè canaliculatis, deinde convexis; sordidè olivaceâ, striatâ et malleatâ, fasciis angustis pallidè virescentibus cingulatâ; aperturâ pyrifomi-oblongâ, peramplâ; fauce livida- purpureâ.

Shell compressly ovate, very ventricose, scarcely umbilicated, spire small, rather immersed, whorls impressly channelled at the suture, then convex; dull olive, striated and malleated, encircled with narrow faint green bands; aperture pyriformly oblong, very large; livid purple in the interior.

It was considered a synonym of Pomacea canaliculata by Thompson (1997)[3] based on shell morphology, but tentatively retained as a separate species by Cowie & Thiengo,[4] because of its reported production of green eggs.

[5][2] The nonindigenous distribution includes the United States: Loxahatchee National Wildlife Refuge waters in Palm Beach County, Florida.

[2] Pomacea haustrum were discovered in the late 1970s in Palm Beach County Florida, and have not spread appreciably in 30 years.

[5] Pomacea haustrum is currently of relatively minor concern in the U.S., given its failure to spread beyond Palm Beach County after 30 years or more in Florida.
