Description
This slug species is pale beige-greenish to beige-grey, sometimes also yellowish-orange, with blackish narrow lateral bands having clearly marked upper edges and blurry lower edges, running from posterior end to frontal section of mantle, above the pneumostome.[2] The shape of the slug is elongate, dorso-ventrally flattened (oval in transversal cut).[2] The head is very short (only 2–3 mm protruding from under the mantle).[2] Tentacles are brown and long.[2] Mantle length covers 35% of body.[2] There are 26 grooves between medial line of dorsum and pneumostome.[2] Sole is dirty cream, transparent (viscera visible in live slugs), medial section narrower than lateral sections and slightly concave.[2] Mucus is colourless and thin, also when irritated, sometimes with orange hue.[2] Mucus secreted onto the ground while crawling breaks into thin threads and coagulates into a unique spider-web like pattern, not seen in Arion species.[2]
The length of the body is up to 80 × 10.5 mm (preserved 58 × 11 mm).[2]
