Material examined — Holotype ( ZMH140809 View Materials ): shell height 3.1 mm, width 1.8 mm; paratypes: 96 specimens in isopropanol ( ZMH140810 View Materials ), 16 specimens coll. Glöer.
Type locality — Greece, Evia Island , the region of Mount Ochi, GR 15 Kastanolongos, helocrenic spring, 38°3'8.72"N, 24°28'15.83"E, 01.07.2007 leg. Pešić. GoogleMaps
Etymology — Named after the beautiful chestnut tree forest (“Kastanolongos”) on the slopes of Mount Ochi ("Oche") where the locus typicus of the new species is located.
Description
Shell — Cylindrical with 4.5 slightly convex whorls with a deep suture. The body whorl has a straight vertical tangent line. The aperture is ovate, slightly angled at the top. The peristome is sharp with a brown periostracum. The umbilicus is closed. The shell is 2.8-3.1 mm high and 1.8-1.9 mm broad.
Animal — The head is light-brown with a white border.
Anatomy — The penis is much shorter than the penial appendix ( Fig. 7 View Figures 2-10. 2 ). Tubular gland thin at the proximal end, broader at the distal part, with four half-loops.
Differentiating characters — The new species resembles Bythinella charpentieri . The latter species was recently redescribed by Georgiev & Glöer (2020) on the basis of a syntype material from Hymettus, Attica. The shell of B. charpentieri is elongated conical and not cylindrical as in B. kastanolongosensis n. sp. Moreover the tangent line of the body whorl in B. charpentieri is not straight as in the new species ( Fig. 2 View Figures 2-10. 2 ). The shell of B. dimitrosensis , a species known from southern part of the island of Evia, is ovate and the species is smaller than B. kastanolongosensis n. sp.
Due to its size the new species is similar to B. reuselaarsi n. sp. (see there for further discussion).
Habitat — Specimens were collected from the stones in a small seepage spring in old-growth chestnut wood ( Fig. 11 View Figures 11-12 ).
Distribution — Greece; only known from the type locality in the southern part of the island of Evia.
