The Maltese letter 'għ' in taxonomy

The 9th letter of the Maltese alphabet is a digraph written as and pronounced 'għajn' (aighn in English). In speech, it is a silent consonant which has the function of lengthening the succeeding vowel, therefore a word written as 'għar' (meaning 'cave') would be pronounced something like 'aar'.

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 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 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]?

  1. You can't set pronunciation rules for taxonomic names. People pronounce any way they want. How is a person who doesn't know Maltese suppose to know what "gh" actually stand for?

    Even the "straightforward" names have varying pronunciations. An example is the common northeast U.S. land snail Venridens ligera. Some, including myself, pronounce the g in ligera like a hard g, while others like a soft g. Who is right?

  3. I always find the restriction to the 26 'Latin' letters in itself interesting, since at least one of those letters (W) could be argued to be almost as unique to English and a couple of other northern European languages as other letters are to eastern European languages.

  4. Indeed, and in my opinion this is one very interesting 'philosophical' difference between binomial names and common names. Whereas common animal names can be used to signify a whole range of objects and metaphors pertaining to them, binomial names in themselves are purely literary creations (ideally) stripped of ambiguity and irrelevant external references, but also devoid of the organic development and cultural context of a language.

    To over-simplify and attempt to answer your (rhetorical?) last question and the similar one I posed, both parties would be right, since pronunciation is an artefact of speech, which is not taken into consideration by taxonomy, and rightly so. Science should remain as objectivist as possible.

  5. OUT OF FINANCIAL MESS WITH THE HELP OF LEXIELOANCOMPANY@YAHOO.COM

    I have been in financial mess for the past months, I'm a single mum with kids to look after. My name is Renee Joan Rothell, and am from Ridley Park, Pennsylvania. A couple of weeks ago My friend visited me and along our discussion she told me about Mr Martinez Lexie of ( Lexieloancompany@yahoo.com ); that he can help me out of my financial situation, I never believed cause I have spend so much money on different loan lenders who did nothing other than running away with my money. She advised, I gave it a try because she and some of her colleagues were rescued too by this Godsent lender with loans to revive their dying businesses and paying off bills. so I mailed him and explain all about my financial situation and therefore took me through the loan process which was very brief and easy.. After that my loan application worth 78,000.00 USD was granted, all i did was to follow the processing and be cooperative and today I am a proud business owner sharing the testimony of God-sent Lender. You can as well reach him through the Company website: http://lexieloans.bravesites.com OR text: +18168926958
