Berlandina nakonechnyi sp. n.

Figs 74–82

Material: MONGOLIA, Khovd Aimag: holotype ♂ ( ISEA), 33 km SW from Altai Village, Bodonchiyn-Gol River Valley, 45º46’17”N, 92º12’52”E, stony desert, 1300 m, 6–7.05.2012 (AF). Paratype: 1♂ ( ISEA), 36 km SW from Altai Village, Bodonchiyn-Gol River Valley, 45º45’N, 92º11’E, stony desert, 1300 m, 07– 08.05.2012 (AF).

Etymology. The specific name is a patronym in honour of our friend Alexandr N. Nakonechnyi (Novosibirsk, Russia), an entomologist who helped to organize an expedition to Mongolia in which some new species of Berlandina were collected.

Diagnosis. The new species is similar to B. saraevi and B. yakovlevi sp. n. From the former species it differs by having a stronger ventral lobe of the palpal tibia (cf. Figs 70 and 75 ) and abrupt tip of the embolus (gradually tapering in B. saraevi ). The two sibling species B. nakonechnyi sp. n. and B. yakovlevi sp. n. differ by having a distinct tooth (spine) on the retrolateral tibial apophysis in the former species ( Figs 75, 78 ) which is lacking in the latter (represented as ridge, Fig. 89 ); proportions of embolus (wider and shorter in B. nakonechnyi sp. n., cf. Figs 74, 79 and 83, 87 ) and also by the tip of the embolus, which has a bifurcate outgrowth in B. nakonechnyi sp. n. ( Fig. 81 ), lacking in B. yakovlevi sp. n. ( Fig. 86 ). Berlandina nakonechnyi sp. n. and B. yakovlevi sp. n. differ also by the darker abdomen and less distinct long dense stretching hairs on tibiae-tarsi I and II in the former species (cf. Figs 82 and 90 ).

Description. Male. Total length 5.9. Carapace: 2.9 long, 2.25 wide. Coloration: carapace dirty-yellow. Chelicerae brown. Sternum, maxillae, labium, palps and legs yellow. Abdomen grey dorsally and yellow ventrally. Spination of leg IV: femur: d1-1-0(1), p0-1-1, r0-0-1; patella: p1-0, r1-0; tibia: d1-0-1, p1-1-1, r1-1-1, v2-2 -2; metatarsus: d1-2-0, p1-1-0, r1-1-0, v2-1 -2.

Leg article length.

Palp as in Figs 74–81 ; tibia with well developed ventral lobe and two tibial apophyses: one large, as long as tibia, and second small, tooth-like hidden by larger apophysis; tibia with three dorsal spines; embolus long and massive with two small lobes near tip ( Fig. 81 ) and ridge on the dorsal side ( Fig. 80 ). Female unknown.

Distribution. Known from the type locality only.
