Name
Haploptychius sp. – Wikispecies link – Pensoft Profile
Material examined
Locality no. 6: CUMZ-CM179 (1 specimen in ethanol). Locality no. 11: CUMZ-CM074 (12 shells; Fig. 9C), CUMZ-CM075 (1 shell), CUMZ-CM076 (14 specimens in ethanol; Fig. 4A). Locality no. 12: CUMZ-CM098 (8 shells), CUMZ-CM099 (1 shell), CUMZ-CM100 (9 specimens in ethanol). Locality no. 13: CUMZ-CM121 (21 shells), CUMZ-CM122 (1 specimen in ethanol). The snails were found to live on the ground among leaf litter in the limestone area.
Remarks
This species is similar to H. michaui (Crosse & Fischer, 1863), but the latter is more ovate and less oblique in shell shape. In addition, this species can be distinguished from H. pellucens (Pfeiffer, 1863), H. porrectus (Pfeiffer, 1863) and H. perlissus Vermeulen et al., 2019 by having strong and prominent radial ridges. For comparison, the latter three species have a smooth to nearly smooth shell surface, H. pellucens has an oblique-ovate shell shape, H. porrectus and H. perlissus have an oblique heliciform shell shape (see Inkhavilay et al. 2016[1], and Vermeulen et al. 2019b[2] for further comparison).
