Material examined — Holotype ( ZMH140807 View Materials ): shell height 3.1 mm, width 1.9 mm; paratypes: 64 specimens in isopropanol ( ZMH140808 View Materials ), 15 specimens in coll. Glöer.
Type locality — Greece, Evia Island , the region of Mount Ochi, GR 4 limnocrene spring within Platanus grove along the road, near Melissonas village, 38°5'26.43"N, 24°23'54.97"E, 30.06.2007 leg. Pešić. GoogleMaps
Etymology — Named after Robert Reuselaars (Assen, The Netherlands) in appreciation of his work in collecting Bythinella samples in Greece.
Description
Shell — Shell ovate-cylindrical with 4.5 slightly convex whorls separated by a deep suture. The aperture is ovate, somewhat oblique. The peristome is sharp. The umbilicus is closed. The shell is 3.1 mm high and 1.9 mm broad.
Anatomy — The penis is much shorter than the penial appendix. The tubular gland is thin at the proximal end and brod at the distal end ( Fig. 10 View Figures 2-10. 2 ), with six half-loops.
Differentiating characters — The shell of Bythinella reuselaarsi n. sp. is ovate-cylindrical, not elongated like in B. charpentieri . On the other hand, B. dimitrosensis can be distinguished from the new species by a smaller size, ovate shell. The body whorl of B. reuselaarsi n. sp. is convex and not straight like in B. kastanolongosensis n. sp. The tubular gland of B. reuselaaarsi n. sp. is longer (6 half-loops) vs. four half-loops in B. kastanolongosensis n. sp.
Habitat — Specimens were collected from a limnocrene spring with a well developed starwort ( Callitriche sp. ) vegetation ( Fig. 12 View Figures 11-12 ).
Distribution — Greece; Only known from the type locality in the region of the Mt. Ochi in the southern part of the island of Evia.
