Diagnosis

Species of the N. b. complex with highly arched, symmetrical Pa-Tr dorsal margin, concave dorsal margin of Pa-Ti and equilateral triangular glans, and Rec sem of 5 elongated vesicles attached to a bladder.

Etymology

The species name ʻ kozari ʼ is dedicated to Senad Kozar (Travnik), whose friendship and hospitality helped us in a searching expedition on the Vlašić planina Mts.

Description

Male (holotype)

BODY. Length 1.90, body width: 1.41.

CHELICERAE. Ch basal article (without Apo) length 0.61, 2.0 times as long as wide at Ch max width at dorsal hump. Ch-Apo small, 0.24 times as high as basal article length, rounded-trapezoid, widest distally; Ch-Apo height 0.14, max width 0.12, min width 0.09 (at the base), ventral margin slightly concave. Secretion field apically. Distal article length 0.60, max width 0.19, movable finger length 0.23 (Figs 4F, 6F, 9F).

PEDIPALPS. Pa-Tr relatively very high (Pa-Tr height:length ~ 0.7:1), Pa-Fe moderately robust (Pa-Fe min:max width ~1:2.7), with 4 subequidistant stout spines in the distal Pa-Fe third. Pa-Pt relatively thin (length:max width ~1:4.5), Pa-Ti dorsally conspicuously concave (Figs 5F, 6F). Pa article lengths in Table 9.

PENIS. Pe length 1.55, base 0.60, glans 0.13, stylus 0.04 (Figs 7F, 8F).

LEGS. Pseudoarticle leg-Fe formula I−IV: 0−1−1−2. Tarsomere leg formula I−IV: 8−14−8−9. Leg article lengths in Table 9.

Female

BODY. Length 2.03, body width 1.67.

CHELICERAE. Ch basal article length 0.63, 2.4 times as long as wide at dorsal hump, with slightly arched dorsal margin in front of indentation, and slightly concave ventral margin (Fig. 13E). Distal article length 0.66, max width 0.23, movable finger length 0.28.

PEDIPALPS. Pa-Tr with moderately high, arched dorsal margin, Pa-Fe with conspicuous distal bonce, Pa-Pt and Pa-Ti elongated (Fig. 13E). Pa article lengths in Table 9.

OVIPOSITOR. Ovipositor length 0.93, Rec sem consisted of bladder and 5 elongated sac-like vesicles (Fig. 11F).

LEGS. Leg lengths in Table 9.

Distribution

Bosnia and Herzegovina, probably endemic to the Vlašić planina Mts. Vertical distribution: 1550−1630 m a.s.l. Type locality: Mrazišče, Mt. Paljenik in the Vlašić planina Mts, Travnik (44.28° N, 17.63° E, 1550 m a.s.l.), Bosnia.

Ecology

Nemastoma kozari sp. nov. individuals have been found in light submontane beech and fir forests, but may inhabit also other vegetation types. Phenology: adults probably eurychronous.
