Holotype: Shell minute (height 2.0 mm, diameter 1.1 mm), sinistral, thin, elongate, conical in first whorls then cylindrical; colour white, subtranslucent. Whorls 5.2, inflated, strongly rounded, separated by a deep suture. Protoconch 1.5 whorls, smooth; protoconch / teleoconch transition distinct because of change in sculpture; surface of teleoconch with lamellate axial ribs (27 on body whorl) and distinct minute spiral striae between the ribs. Body whorl rounded, ventrolaterally with a distinct bulge through which an inner, palatal, crescent-shaped denticle can be seen. Aperture almost circular; upper insertion of the peristome not descending; peristome continuous but the upper part largely merged to the preceding whorl, double, weakly expanded and thickened; there is a columellar lamella at the bottom of the columella, which can be fully seen only by looking through the aperture (also indistinctly visible in frontal view in the aperture); perforate, umbilicus marked by the continuation of the axial ribs. Operculum unknown. Paratypes: Operculum ~ 0.5 mm, corneous, concave, almost completely circular in shape, completely transparent and whitish. Body (5) colourless and transparent; except for the ca two first whorls where the light brown odd caesura can be seen by transparency. Eyes black, quite minute, at the base of the tentacles. Tentacles ~ 0.2 mm long, cylindrical, extending upward.	en	Gargominy, Olivier, Fontaine, Benoît, Tercerie, Sandrine, Zuccon, Dario (2025): New species and new records of families, genera and species of land snails (Mollusca, Gastropoda) from French Guiana.

4C0AA735850B5857848F6324AA1CC5F2.taxon	etymology	Etymology. The species is named after Quasimodo, the hunchback character of Victor Hugo’s novel Notre-Dame de Paris, and refers to the bulge on the body whorl. It also reminds one of the catastrophic event of the fire at Notre-Dame de Paris cathedral on 15 April 2019, which occurred during the Trinité collecting trip. Treated as a noun in apposition.	en	Gargominy, Olivier, Fontaine, Benoît, Tercerie, Sandrine, Zuccon, Dario (2025): New species and new records of families, genera and species of land snails (Mollusca, Gastropoda) from French Guiana.

31E03958D2D25780929D768B7EF0014B.taxon	description	Description. Holotype: Shell minute (height 2.2 mm, diameter 2.6 mm), dextral, globose, dome-shaped to gibbous, thin; colour corneous; whorls 5.4, inflated, rounded, separated by a deep suture; spire coiling regularly increasing. Protoconch two whorls, smooth; protoconch / teleoconch transition distinct because of change in sculpture; teleoconch sculpture of regular radial ribs, 60 on the body whorl, and a reticulate pattern consisting of fine growth-striae and dense microscopical spiral threads between the ribs. Body whorl rounded. Aperture almost circular; upper insertion of the peristome not descending towards the aperture; suture impressed. Peristome simple, sharp, neither expanded nor thickened. Umbilicus U-shaped, almost cylindrical, contained 3.8 × in the shell greater diameter. Animal greyish, sole paler; tail without distinct caudal pit, not distinctly truncated; ocular tentacles long and gracile, inflated at the tip; eyes black, small, on the upper front of the tentacles (Fig. 7). Paratypes: Juveniles have internal lamellae which are dissolved (not present) in adult specimens (more than 4.5 – 5 whorls, as the holotype): a longitudinal lamella in the middle of the parietal wall formed by up to three (one or two in subadult specimens) elongate, high (~ 40 % of the aperture diameter) teeth separated by gaps of half their length, covering ~ 1 / 8 whorl in length; at the opposite palatal side of each parietal tooth, there is a transversal lamella, extending from the outermost side of the aperture towards half of the columellar wall, principally thickened in front of its corresponding parietal tooth and extending a little bit inside along the whorl. In early juveniles this palatal lamella is reduced to a simple denticle. The lamellar complex reduces the aperture diameter to half its value.	en	Gargominy, Olivier, Fontaine, Benoît, Tercerie, Sandrine, Zuccon, Dario (2025): New species and new records of families, genera and species of land snails (Mollusca, Gastropoda) from French Guiana.
