Architaenioglossa
superfamily Cyclophoroidea
Members of the superfamily Cyclophoriodea are operculate, terrestrial snails, distributed widely in the tropics and subtropics, with a few species in warm temperate areas. Distributions were taken from “Compendium of Landshells” by R. Tucker Abbott, the website malacos.chez.com, and the Discover Life website. There seems to be much confusion surrounding the content of the Cyclophoroidea. Bouchet & Rocroi, 2005 [Classification and Nomenclature of Gastropod Families. Malacologia 47 (1-2): 1-397] recognize eight extant families, all of which appear to have some terrestrial species; Aciculidae, Craspedopomatidae, Cyclophoridae, Diplommatinidae, Maizaniidae, Megalomastomatidae [=Megalomastomidae, Megalostomatidae, see below], Neocyclotidae and Pupinidae. Some authors do not recognize Neocyclotidae as separate from Cyclophoridae. Other classifications include recognition of the families Cochlostomatidae, Liareidae, and Poteriidae, which Bouchet & Rocroi (2005) place as subfamilies within the Diplommatinidae, Pupinidae, and Neocyclotidae, respectively. The arrangement below follows Bouchet & Rocroi (2005) as closely as possible, recognizing that they do not list genera, but do list subfamilies, which allows some cross-tracking.

family Maizaniidae
A small family with one genus.
Genera:
| Maizania | East Africa, Kenya |
family Megalomastomatidae
A small family with much confusion at several levels. First, there is disagreement on membership, ranging from one genus, Cyclopilsbrya (with one species, C. stiosa, from Jamaica) according to the Discover Life website to Abbott’s [1989. Compendium of Landshells] recognition of seven; Acroptychia (Madagascar), Aperostoma (mispelled “Akerostoma” on page 208, but spelled correctly on page 44), Cyclojamaica (Jamaica), Farcimen (Cuba), Hainesia (Madagascar), Megalomastoma (Lesser Antilles & Peurto Rico)and Tomocyclus (Guatemela), to the malacos.chez.com web site’s list of ten genra, including all of the above plus Anosyclos (Madagascar) and Boucardicus (Madagascar). Second, Abbott (1989) lists the seven genera above as members of the Megalostomatidae on page 208, but they all appear to be under Poteriidae [=Neocyclotidae here] on pages 44-45. Finally, there are several spellings of the family name in the literature. Bouchet & Rocroi (2005) use Megalomastomatidae (thus the heading for this section), but Abbott (1989) uses Megalostomatidae and still others use Megalomastomidae. Here I will follow the Discover Life website and include only Cyclopilsbrya. The remainder of the genera above are found in Neocyclotidae and Cyclophoridae.
Genera:
| Cyclopilsbrya | Jamaica |
family Neocyclotidae [=Poteriidae]
This is a large family of the New World tropics and subtropics (with the exception of two genera found in the South Pacific). As mentioned above some authors do not recognize Neocyclotidae as a separate family and place most of these genera in the Cyclophoridae, Megalomastomatidae and/or Poteriidae. Interestingly, the Discover Life web site lists Hainesia (see above under Cyclophoridae) under both Cyclophoridae and Neocyclotidae. I believe they are correctly placed in the Cyclophoridae based on distribution.
