Hadzinia Šilhavý, 1966

Diagnosis. Genus of very small, long-legged troglobite Nemastomatidae characterized by specific penis and pedipalp structure. Glans penis wider than trunucs and terminally bifurcated. Trochanter and tarsi of pedipalps elongated, with tarsus almost as long as tibia. Ocular tubercle and eyes reduced. Male cheliceral apophysis and cheliceral gland openings absent.

Material examined. 1 ♂, from the type locality Cave Resanovačka pećina Ledenica, Drvar, Bosnia and Herzegovina, 06.V 2011, leg. R. Ozimec.

Body length 1.2. Dorsum soft, without firmly structured chitin sculpture. Prosoma and medial pair of supracheliceral lamellae sparsely covered with mammillary structures ( Fig. 15 ). Ocular tubercle absent. Ventral side of the body covered with sparse elongated setae (in a transverse row along the posterior border of each sternite).

Chelicerae elongated ( Fig. 8 ), basal segment length 0.77, distal segment length 0.83, chela length 0.27. Basal segment terminally slightly widened; without apophysis and secretion pore. Distal segment wide; frontally covered with long setae.

Pedipalps ( Fig. 9 ) elongated and slender. Length of palp segments: Tr 0.59, Fe 1.61, Pt 1.34, Ti 1.08, Ta 0.89, total 5.51 mm. Trochanter stout and straight, relatively long (one third of the Femur length), unarmed. Femur curved in an S-shape (lateral view). Patella almost straight, basal part much wider, narrowing after midsection and distal part slightly bent to ventral. Tibia slightly curved to dorsal, somewhat shorter than Patella. Tarsus long, almost of the same length as Tibia, curved along its whole length to ventral.

Glans ( Figs 10–13 ) wider than tip of the truncus; slightly flattened dorso-ventrally, with a wide shallow furrow ventrally, terminally bifurcated; covered with sparse minute spines, a group of three on the bifurcations tips. Stylus pointed, set in the center between the bifurcation tips as a thin separate tube.
