Troglocaris (Troglocaris) bosnica Sket et Zakšek, 2009

Synonymy: Troglocaris sp. nov. 2 of the Bosnian clade, Zakšek et al., 2007

Specimens examined: Suvaja pećina cave, Sanski Most, Bosnia and Hercegovina: 1 juvenile male, CL 6.2 mm; 13 mature females, CL 5.8–7.4 mm; 4 juvenile females, CL 5.0– 5.5 mm. Dabarska pećina cave, Sanski Most, Bosnia and Hercegovina: 1 adult female, CL 8.8 mm (voucher numbers are in Appendix C8; for GenBank identification numbers for COI gene see Sket & Zakšek 2009).

Emended diagnosis: Species of Troglocaris sg. Troglocaris with completely reduced eye and body pigmentation. As for the subgenus, rostrum length 55 % of CL or longer, usually with 13 or more ventral teeth (exceptionally 12–10 teeth); palp of maxilla I with more than three, moderately long setae; male pleopod I endopodite with more than 30 partially grouped, and long, inner marginal setae. Pereopod V exopodite well developed.

Remarks: Males: the holotype was the only adult male available. Except for the age dependent characters (pereopod III–IV article 6 differentiation), no other differences from the species diagnosis (Sket & Zakšek 2009) are present in the only juvenile male. Females: no differences from the species diagnosis (Sket & Zakšek 2009) present.

It should be stressed that not only all adult males and females (in contrast to the vast majority of T. aggr. anophthalmus specimens), but also all juveniles have well developed exopodites on pereopod V.

Distribution: The subspecies is known only from two caves in Bosanska Krajina (westernmost Bosnia and Hercegovina, Figure 1 ). The populations from the Bihaċ region between Lušci polje ( Bosnia and Hercegovina) and Kukuruzoviċa peċina ( Croatia) were available neither for molecular nor for the morphometric study; they could belong to this or to any of the neighbouring taxa.
