03F487E93974FFDAFD5B8D12FC5A2B20.taxon	materials_examined	Type material. Holotype: MZSP 106226 (sta. LES 2205) (Figs 1 - 4). Paratypes: MZSP 106237, 1 shell from type locality (sta. LES 2204) (Fig. 5); MZSP 104837, 2 shells of uncertain locality (possibly same as the type locality) (sta. LES 2068) (Figs 6 - 7). Type locality.

03F487E93974FFDAFD5B8D12FC5A2B20.taxon	diagnosis	Diagnosis. Shell background colour pale beige to cream, with brownish-purple blotches occupying ~ 40 % of surface. Sculpture axially elongated, minute nodes arranged in spiral rows (9 - 10 on penultimate whorl). Aperture wide, with relatively straight inner lip. Umbilicus wide for genus.	en	Luiz Ricardo L.

03F487E93974FFDAFD5B8D12FC5A2B20.taxon	description	Description Shell (Figs 1 - 6). Outline fusiform; height about 47 mm, width ~ 42 % of length; ~ 5.5 whorls (Fig. 4). Background colour pale beige to cream, with brown to brownish-purple markings, blotches, occupying ~ 40 % of surface; blotches irregularly arranged in spiral pattern, resulting in 4 equidistant bands on last whorl (Fig. 2). Lower part of body whorl devoid of colour markings; in apertural view (Figs 1, 5, 6) large, light-coloured region, well delimited by distinct, oblique line beginning at junction of columellar and parietal areas, extending downwards, joining white peristome; in dorsal and basal views (Figs 2 - 3, respectively), light-coloured area forming spiral light colour band surrounding umbilicus. Protoconch of 1.5 whorls, rounded profile, with flattened superior surface, weakly carinate in superior region, sculptured by delicate net of axial and spiral lines (Fig. 7), ~ 10 spiral lines on first whorl; occupying ~ 15 % of superior shell surface in apical view (Fig. 4); diameter ~ 3.5 mm. Spire acuminate, occupying ~ 55 % of shell length; spire angle ~ 35 - 40 °; suture shallow, whorls weakly convex. Teleoconch sculpture of well-developed growth-lines and axial undulations; surface additionally wrinkled by small, axially elongated nodes on top of undulations, arranged successively in spiral lines, ~ 9 - 10 on penultimate whorl (Fig. 2); each node ~ 3 times as long as wide. Body whorl occupying ~ 2 / 3 of shell length, not more elongated than previous whorls. Aperture completely white, ~ twice longer than wide, elliptical; anterior notch well-developed, almost siphon-like, anteriorly directed (Fig. 3); outer lip weakly convex, edge thick, expanded, thereby increasing shell width ~ 15 %; edge weakly narrower superiorly, gradually becoming wider in inferior portion (Figs 1, 5, 6); edge thinner in anterior notch; superior half of inner lip almost straight, callus thin, translucent (Figs 1, 5, 6), inferior half similar to outer lip, almost straight and with uniform width along its length. Umbilicus relatively wide (Fig. 3), partially covered by expansion of inner lip; possessing shallow spiral marginal furrow. Measurements (in mm). Holotype: 46.9 by 20.0; MZSP 106237: 46.2 by 20.1; MZSP 104837 # 1: 40.9 by 18.4; # 2: 36.2 by 15.2 (subadult specimen without expanded peristome). Habitat. Found dead inside caves, possibly carried in by floods, so, considered accidental in the caves, having come from epigean, possibly arboreal environment.	en	Luiz Ricardo L.

03F487E93974FFDAFD5B8D12FC5A2B20.taxon	etymology	Etymology. This species is named after Maria Elina Bichuette, Universidade Federal de São Carlos, who is leading a team conducting extensive projects on cave faunas and has donated several mollusc samples resulting in a significant improvement of our knowledge of the Brazilian malacofauna.	en	Luiz Ricardo L.
