Diagnosis: shell flat, lentiform, usually not haired, with a blunt keel, parietum with a very thick callus, vagina completely reduced,

Description of shell: shell flat, lentiform, basic colour light brown to yellowish-brown; initial 1–1½ of the teleoconch whorls smooth, then with a fine and dense radial sculpture, becoming stronger on the subsequent whorls, developing to small riblets; ventral side of the shell usually with fine radial stripes only, sometimes with small riblets; whole shell with a dense granulation; shell usually not haired, but if so, then restricted to a narrow stripe just above the blunt peripheral keel (hairs 0.5–0.8 mm, yellowish); shell with 5½–7 regularly increasing and flat whorls, with a blunt keel; shells tend to produce scalarid forms (see remarks); suture shallow; last whorl slightly ascending, but descending before the aperture with a white coloured area; umbilicus dish-like, perspective, diameter 1.7–3.3 mm; aperture very oblique, slightly curved in lateral view; in frontal view of semi-circle form, peristomial insertions with a gap of 2–3.1 mm, parietal callus a very thick, bar-like structure; peristome sharp, broadened apically and laterally, often slightly reflected basally.

Measurements (in mm): H: 3.1–4.7; D: 9.1–13.3; aH: 2.5–4.7(1.4–2.8); aW: 3.4–5.3.

Details of body (according to 6 animals from 4 km of Kehrókambos in direction of Stavroúpoli): head and dorsum dark brown to grey; sole cream with brownish lateral rims; mantle above the secondary ureter with one stripe of dark-brown pigmentation; secondary ureter opens 0.5–1 mm from the pneumostome.

Morphology of the genital organs ( Fig. 28 View Figs 26–28 ): penis relatively short, slightly thickened, penial glandular tissue covers only 1/4 of total penis length, penial lumen with two large pilasters with one of them starting at the proximal penial wall and stretching to the penial pore, the second branching into two arms before reaching the proximal penial wall, several small, perpendicularly arranged accessory folds present; vagina completely reduced, glandula and bursa copulatrix branch off the atrium, glandula with a short stalk and a long and scarcely folded part; bursa copulatrix reaching the length of the glandula or somewhat shorter, vesicle almost not discernible; atrial lumen filled with a large, broad and flat, pillow-like pilaster, connecting to a few short folds.

Differential diagnosis: On average, L. spectabilis is larger than L. reischuetzi . Equally sized shells can always been identified as L. spectabilis by its larger aperture, the weak palatal callus, and the usually narrower umbilicus. The reduced vagina is a clear autapomorphic character that separates L. reischuetzi from all other species of Lindholmiola .

Around the Bay of Korinthos, there is a strongly keeled form of L. lens (callojuncta), which somewhat resembles L. reischuetzi . This form of L. lens , however, has a larger shell, and its palatal callus is only slightly reinforced. Other forms of L. lens have a more raised spire and always a weak palatal callus.

Remarks: Shell size variations in L. reischuetzi are few. However, next to the widespread typical form of this species, there are two local forms that need to be mentioned: 1) the populations east and northeast of Dráma to the Lekánis Mountains (for example in Makriplágio, Taxiárhis, Ipsilí Ráhi, Nikifóros etc.) tend to build scalarid shells. The whorls of this form are stepped, and often the ventral side of the shells is covered by riblets; 2) the easternmost populations of L. reischuetzi (for example close to Stavroúpoli and N of Xánthi) have flat shells with rapidly increasing whorls. It has to be stressed that these character states are restricted to those populations mentioned. However, on the Island Thássos these forms can be found mixed with the widespread form with all intergrades. For this reason, these local forms cannot be separated as geographical subspecies.

Distribution ( Fig 51 View Fig ): This species is recorded from north-eastern Greece from Makedonía to western Thráki, in the coastal stripe between the Dráma to Xánthi and the sea. It also lives on the islands of Thássos and Thássopoula, and there is a small isolated population in the Southwest of the Halkidikí Peninsula.
