Material studied (total: 2 males, 1 female).

CROATIA: 1 male, 1 female, Dubrovnik, Gromača, Špilja za Gromačkom Vlakom Cave, 28 August 2014, A. Ćukušić leg. ( CNHM).

MONTENEGRO: 1 male, Cetinje, Njeguši, Njegoš Cave, 4 May 2013, T. Delić leg. (IZB).

Distribution. Bosnia and Herzegovina: Vjetrenica Cave in Popovo Polje (type locality) ( Attems 1951, 1959), Dolnja Pećina Cave in Kijev Do ( Attems 1959); Croatia: (present study, see above), Montenegro: (present study, see above) ( Fig. 20 , open white circles). Until the study here, this species was known only from two caves in Bosnia and Herzegovina. Typhloiulus edentulus is a new species for the faunas of Croatia and Montenegro.

Notes. Vagalinski et al. (2015: 339) stated that the gonopods of this species were illustrated for the first time by Strasser (1962: 34, fig. 35), but this is not correct. The first illustration of this species was given posthumously by Attems (1959: 390, 391, figs 197–204).

Typhloiulus edentulus is one of the four Typhloiulus species with modified mouthparts and an assumed hydrophilous lifestyle, together with T. ausugi Manfredi, 1953 from Italy, T. balcanicus Antić, 2017 from Serbia, and T. serbani ( Ceuca, 1956) from Romania. As stated by Enghoff (1985) and Antić et al. (2017), hydrophilous Typhloiulus species are characterized by the presence of a shorter body with a smaller number of body rings, ranging from 29 to 38, compared with non-hydrophilous congeners. The specimen of T. edentulus from Montenegro has a somewhat larger body and 43 body rings plus telson.

The species is known only from caves.
