Specimen examined: Microslide ZMB 42551, Nr. 4395 female, labelled Laelaspis markewitschi Pirianyk, 1959 , Det. Pirianyk, 5.10.1968, coll. Duderenko.

Notes. This species was collected in soil, forest litter, rotten stumps, ant and rodent nests in Russia and Ukraine. Its genitoventral shield is not markedly widened behind coxae IV; Zv1 and Jv1 setae are off the genital shield close to its lateral margins; the dorsal shield has 40 pairs of setae, which possess a small knob at their bases ( Fig. 27 ); the epistome has a denticulate anterior margin ( Fig. 28 ); the palp chaetotaxy is normal (sensu Evans & Till, 1965), with acicular setae, except al on femur and al1–2 on genu thickened; and the palp tarsal claw is twotined ( Fig. 29 ). Gwiazdowicz et al. (2014) described the presternal shields in Cosmolaelaps . In some species the presternal plates may be fused with the anterior margin of the sternal shield; in this case the anterior margin of the sternal shield has a small notch with a small reticulated bulge on each side, so the first pair of sternal setae (st1) and iv1 were located behind the anterior margin of the shield; for example C. serratus Trägårdh , C. simplex v. digrediens (Berlese) , C. guttulata (Karg) , C. bipennata (Karg) , and C. markewitschi (Pirianyk) ( Fig. 30 ).

Joharchi et al. (2012) excluded this species from Laelaspis due to the absence of the characteristic ornamentation of the genital shield, and transferred it to Gymnolaelaps , but based on the above explanation this species has the main characters of Cosmolaelaps and we considered it as a member of this genus.
