Bielzia coerulans is a species of very large land slug, a terrestrial pulmonate gastropod in the family Limacidae, the keelback slugs.
Taxonomy
Bielzia coerulans was discovered and described under name Limax coerulans by Austrian-Hungarian malacologist Michael Bielz (1787-1866) in 1851. (His son Eduard Albert Bielz was also malacologist.)
Bielzia coerulans is the only species in the genus Bielzia.[5]
Some authors, for example Russian malacologists,[4] classify genus Bielzia as the only genus (monotypic) within separate family Limacopsidae Gerhardt, 1935.[6][4] There has been also created separate subfamily Bielziinae I. M. Likharev & Wiktor, 1980 for genus Bielzia.
According to the taxonomy of Bouchet & Rocroi (2005) are Limacopsidae and Bielziinae synonyms for Limacinae.[7]
Distribution
This species is endemic to the Carpathian Mountains in Eastern Europe.
The type locality of Bielzia coerulans is South Carpathians in Romania.[4]
- Czech Republic - in Moravia only, vulnerable (VU) in Moravia[8][9]
- southern Poland[5]
- Slovakia[10]
- Ukraine[4]
- Romania[4]
Description
This is a slug which is blue when adult and 100 - 140 mm in length.[11] Slug evenly blue or bluish green (occasionally black) with dark greyish head and tentacles, margins pale yellowish, sole pale yellowish or whitish.[11]
Juveniles are yellowish brown with dark lateral bands.[11]
Reproductive system: Genitalia are without penis.[11] There is only an accessory organ for the copulation.[11]
Ecology
Bielzia coerulans inhabits deciduous and coniferous forests in mountains, usually at the bottom, or under dead wood logs.[11]
Maturity is in June to July.[11] Copulation occur at the soil.[11] There are 30-80 eggs laid in one clutch.[11] Adults die after egg deposition.[11] Half grown juveniles hibernate.[11] Fully grown slugs appear in May.[11]
