Description
Bythinella melovskii n. sp.
(Figures 2-5)
Holotype: Shell height 2.5 mm, shell width 1.4 mm. 19.10.2014 V. Slavevska-Stamenković leg., ZMH 79902.
Paratypes: 7 specimens ZMH 79903, 5 specimens coll. Institute of Biology, Faculty of Natural Science and Mathematics, Skopje, 5 specimens coll. Glöer, 6 specimens destroyed by dissection.
Locus typicus: R. Macedonia, Jablanica Mt., small stream near river Belichka Reka, 41°13'56.7'' N, 20°31'27.0'' E, 1866 m alt.
Etymology: Named after Prof. Dr Ljupčo Melovski, in appreciation of his significant contribution for nature conservation in R. Macedonia.
Description
Shell. Shell greyish and fragile, cylindrical with 4.5 slightly convex whorls with a moderately deep suture. The first two whorls small in height, the other whorls are fast growing. Apex obtuse, umbilicus closed. Aperture oval, angled at its top. Shell height 2.4-2.7 mm, width 1.4–1.6 mm, aperture height to shell height ratio 0.44-0.47.
Soft body. Mantel black with a white border, head dark with a whitish neck, tentacles light with eye spots visible.
Morphology of the penis. Penis shorter than penial appendix, flagellum long and regularly thick, translucent.
Differentiating features: From the only Bythinella sp. known of this region, Bythinella drimica drimica, it differs in shell morphometry: shell height 1.97-2.31 in B. d. drimica vs. 2.4-2.7 mm in B. melovskii , and shell width 1.13-1.30 in B. d. drimica vs. 1.4-1.6 mm in B. melovskii (measurements of B. d. drimica after Radoman 1983). The umbilicus in B. d. drimica is slit-like, closed in B. melovskii n. sp., and the aperture is in B. d. drimica not angled. The anatomy and penis morphology of B. drimica is unknown. From B. slaveyae it differs in size (shell height of B. slaveyae 2.3 mm vs. 2.7 mm in B. melovskii n. sp.) and the tubular gland which is not regularly thick but thickened distally.
Habitat and ecology: The new species inhabits small, shallow and slow flowing streams created by the surplus water draining from the mire complex. Snails were found on hard substrates at 1866 m altitude.
Distribution: R. Macedonia, known only known from the type locality (Fig. 6).
