Cosmolaelaps latisetis Joharchi sp. nov. (Figures 25–44) Type material. Holotype, female, on the coast of the Sea of Japan (East Sea), Sakhalin Island, Russia, 46°42'49.5"N 141°53'14"E, 11 August 2021, O. Joharchi coll., in the nest of Lasius flavus (Fabricius, 1782) (Hymenoptera: Formicidae) (in TUMZ). Paratypes: two females, same data as holotype (in TUMZ). Diagnosis (adult female). Dorsal shield well reticulate, with 39 pairs of scimitar-like setae, reaching well past base of next posterior setae, Z5 shorter than J5 (ratio of J5/Z5 ≈ 1.5); presternal area poorly sclerotised, sternal shield with lineate-reticulate ornamentation on lateral surface, bearing three pairs of long setae, extending slightly beyond of next posterior setae, ratio of shield length/width (at broadest level) ≃ 0.65; genital shield ratio of length/ width (at broadest level) ≃ 1.9, shield ornamented posteromedially by seven cells flanked by a median Λ-shaped ornamentation, anal shield ratio of length/width (at broadest level) ≃ 1.2, post-anal seta thickened, sparsely barbed, apically bent (hook shaped); distance between genital and anal shields is shorter than length of anal shield, almost all opisthogastric setae well thickened (especially Jv5, apically bent) and arising on minute sclerotised platelet, except Jv1–2 and Zv1. Fixed digit of chelicera with five teeth, including two large proximal teeth (posterior to pilus dentilis). Legs without spatulate setae but most setae conspicuously thickened and some inserted on small tubercles. Legs I and IV shorter than length of idiosoma. Description. Female (n=3) Dorsal idiosoma (Figs 25, 30, 32, 33). Dorsal shield semi-circular, large, reticulate throughout, 498–512 long, 404–410 wide, covering entire dorsal idiosoma. Shield with 39 pairs of very long scimitar-like setae, 22 podonotal, 17 opisthonotal, including two pairs of Zx setae between J and Z setae, and three unpaired setae Jx between J2 and J4, setae reaching well past base of next posterior setae, mostly subequal in length (60–73), all ...
