Subspecies
According to Gittenberger & Uit de Weerd (2009) the species Inchoatia haussknechti include 4 subspecies:
Inchoatia inchoata inchoata
Synonyms include:
Diagnosis: The shell is hardly different from Inchoatia inchoata paramythica. Teleoconch is with prominent white papillae, continuing as blunt riblets in the background shell colour, on most of the whorls. Parietal side of the apertural border is not protruding. The lamella parietalis reaches the lamella spiralis or is shorter. The lamella columellaris is very low.
Range: This subspecies occurs in the mountains c. 20 km north of Preveza. The type locality is "Zalongo bei Libochovo", Greece, Ipiros, Preveza: Zalongo, 21 km NNW of Preveza, 200 m and 650–725 m alt.
Inchoatia inchoata klemmi
Synonyms include:
Diagnosis: With some white papillae on the initial teleoconch whorls only, following whorls rather glossy, without any riblets. Parietal side of the apertural border is not protruding. Lamella columellaris is very low.
Range: This subspecies is only known from near Platanousa. The type locality is "Platanoussa bei Ioannina [650 m]".
Inchoatia inchoata paramythica
Synonyms include:
This is by far the most common subspecies in Inchoatia.
Diagnosis: The shell is hardly different from Inchoatia inchoata inchoata. Teleoconch with prominent white papillae, continuing as blunt riblets, sometimes whitened but more often in the background shell colour, on most of the whorls. Parietal side of the apertural border is not protruding. Lamella parietalis is reaching beyond the end of the lamella spiralis. Lamella columellaris very low.
Range: Inchoatia inchoata paramythica is known from several localities at relatively low altitudes in Mt Paramithias and the adjoining mountain chains to the north and to the south. The type locality is "Gliki 4 km Richtung Frosini".
Inchoatia inchoata regina
Synonyms include:
Diagnosis: Teleoconch is with some white papillae on the initial whorls only, following whorls rather glossy, without any riblets. Parietal side of the apertural border is protruding. Lamella columellaris is somewhat protruding into the aperture.
Range: The type locality is "Louros-Durchbruch nahe Ay. Yeoryios bei Arta", Louros gorge (of the Louros river) near Ay. Yeoryios.
