7822FBE4057F5AB1B6A077AC092C87CA.taxon	diagnosis	Diagnosis. Shell minute, elongate-conic (turriform), with relatively narrow spire, whose breadth grows rapidly, acute narrow apex, and narrow but long aperture with prominent lip, distinguishable from the geographically close Paladilhiopsis matejkoi Grego & Gloeer, 2019 from Nemila Spring, Herceg Novi (MNE) and P. montenegrinus (Schuett, 1959, described as Saxurinator) from Bileca (BiH) by its more conical shell shape with slightly pagoda-shaped whorls, sharper apex, and deeper suture. From P. matejkoi it can additionally be differentiated by its more declined aperture.	en	Hofman, Sebastian, Grego, Jozef, Rysiewska, Aleksandra, Osikowski, Artur, Falniowski, Andrzej (2021): Two new species of the Balkan genus Paladilhiopsis Pavlovic, 1913 (Caenogastropoda, Moitessieriidae).

The specific epithet Paladilhiopsis arion refers to the ancient name of River Trebisnjica, which in classical antiquity was known as the Arion, rising and sinking through its course before resurfacing at various places from the Neretva to the coast; Trebisnjica is adjacent to the type locality.	en	Hofman, Sebastian, Grego, Jozef, Rysiewska, Aleksandra, Osikowski, Artur, Falniowski, Andrzej (2021): Two new species of the Balkan genus Paladilhiopsis Pavlovic, 1913 (Caenogastropoda, Moitessieriidae).

3352875A818B5647B707AA71C8B010DB.taxon	diagnosis	Diagnosis. Shell minute, elongate-conic (turriform), distinguishable from the geographically close Paladilhiopsis elongata (Kuscer, 1933) from spring Jadro near Split (HR) by less sinuated lateral labral profile, more inflated and more prominent body whorls, and a more elongate pyramidal shape. From P. solida Kuscer, 1933 from Vrelo Buna in Blagaj (BiH) differs by its smaller less conical shell with less prominent body whorl and slightly sinuate lateral labral margin adapically preceding. Can be distinguished from P. pretneri Bole & Velkovrh, 1987 from Antunovici near Kozice, Makarska district (HR) by its longer, more elongate shell and proportionally smaller body whorl. The receptaculum seminis long and tubular in shape, similar to that of P. bosniaca (Clessin, 1910), and different from the bulbous one with a long duct as in P. grobeni Kuscer, 1928.	en	Hofman, Sebastian, Grego, Jozef, Rysiewska, Aleksandra, Osikowski, Artur, Falniowski, Andrzej (2021): Two new species of the Balkan genus Paladilhiopsis Pavlovic, 1913 (Caenogastropoda, Moitessieriidae).

Shell (Fig. 6 A-P) up to 2.94 mm high and 1.02 mm broad, ovate-conic (turriform), white or whitish, translucent, thin-walled, consisted of ca. six whorls, growing slowly and regularly, and separated by moderately deep but sharply marked suture. Spire high and conic, apex narrow, body whorl height less than 0.5 of the shell height. Aperture small, prosocline, oval, or elongated oval in shape, peristome complete and thin, umbilicus slit-like. Shell surface smooth, glossy, with growth lines hardly visible. Measurements of holotype and sequenced and illustrated shells presented in Table 4. Shell variability slight, marked mostly in breadth: height proportion of the shell and the aperture (Fig. 6 A-P). Radula (Fig. 7 B-D) taenioglossate, typical of Paladilhiopsis, with numerous, long, and cusps. Rhachis formula: (5) 4 - 1 - 4 (5) 1 - 1 or 4 - 1 - 41 - 1 Basal cusps widely triangular and massive, median cusp at the cutting edge 2 x longer than the adjacent ones, lateral tooth formula: 3 - 1 - 4, the largest cusp prominent, nearly 2 x longer than the adjacent ones, on the inner marginal tooth ca. 18 large cusps similar to the ones on the rhachis, ca. 20 smaller and more slender cusps on the outer marginal tooth. Soft parts morphology and anatomy. Body white, with no pigment, with no eyes. Female reproductive organs (Fig. 8) typical of the genus Paladilhiopsis (Hofman et al. 2018), with unpigmented, long, and narrow renal oviduct, large bursa copulatrix, although less elongated than in P. grobbeni, and with its duct (characteristically for Paladilhiopsis) lying proximally, single small distal receptaculum seminis (in the position of rs 1 after Radoman 1973), with the outlet to the oviduct close to the outlet of the duct of the bursa copulatrix, and shortened accessory gland complex. Long narrow loop of the renal oviduct and small short seminal receptacle are characteristic of the species. The simple penis (Fig. 9) typical of the genus, without any outgrowth, tapering, in the form of an elongated triangle.	en	Hofman, Sebastian, Grego, Jozef, Rysiewska, Aleksandra, Osikowski, Artur, Falniowski, Andrzej (2021): Two new species of the Balkan genus Paladilhiopsis Pavlovic, 1913 (Caenogastropoda, Moitessieriidae).
