Several placenames in the Maltese Islands bear the letter għ - Għarb, Bengħisa and Għargħur being a few examples. Taxonomists naming animals from such places for their type locality have to use gh instead of għ in the specific epithet, simply because the ICZN does not allow for any characters other than the 26 of the Latin alphabet (Article 11.2).
Through the literature cited, I was able to come across five such animals described from the Maltese Islands. Clio ghawdexensis Janssen, 2003 is a fossil pteropod named after the island of Gozo, known in Maltese as Għawdex. Trochoidea gharlapsi Beckmann, 1987 is another snail, this time a recent terrestrial species localized mainly around the area of Għar Lapsi ('Lapsi Cave') in southern Malta (juvenile specimen illustrated below, photographed in December 2009).
However, both the above-mentioned type localities are (nomenclaturally) one-offs. The place to boast most species named for it is Għar Dalam (Dalam Cave), which is an extremely important location for fossils of the dwarf elephants and hippopotami that roamed Malta during the Pleistocene. Armadillidium ghardalamensis Caruso & Hili, 1991 is a woodlouse that is endemic to this cave and another one close by (Għar Ħassan). Scolopax ghardalamensis Fischer & Stephan, 1974 is a fossil bird described from the place, though this is now known to be a junior synonym of Coturnix coturnix (Linn., 1758). Finally, Myotis ghardalamensis Storch, 1974, an early Pleistocene bat, probably ancestral to the more modern species.
The million-dollar question is, how would these names, purely hypothetically or actually, be pronounced? Would the Maltese letter għ retain or lose its linguistic characteristics when included in a species' Latinized name? If binomial names were commonly used, would one speak of Trochoidea 'garlapsi' [sic], or Trochoidea 'aarlapsi' [sic]?
