Vitzthumia oudemansi Thor, 1930: 116.
Antennoseius oudemansi.— Athias-Henriot, 1961: 461; Ryke, 1962: 661.
Antennoseius (Vitzthumia) oudemansi.— Bregetova, 1977: 246; Chelebiev, 1984: 1632; Lindquist & Walter, 1989: 1293; Beaulieu et al., 2008: 55; Lindquist & Moraza, 2009: 33; Moraza & Kazemi, 2009: 63; Kazemi & Moraza, 2013: 231; Moraes et al., 2016: 73; Teodorowicz et al., 2014: 27.
Specimens examined. Five females, Kostanay Region, Kazakhstan, 53°18ʹN, 66°27ʹE, 5 September 2019, A.K. Issakova coll., from soil (in TSUMZ).
Remarks. Antennoseius (V.) oudemansi was originally described as Vitzthumia oudemansi from moss and under stones in Norway (Thor, 1930). It is recorded in Kazakhstan for the first time, from soil. Teodorowicz et al. (2014) have re-described this species based on newly collected specimens from the type locality, and designated a neotype for this species because the holotype and paratypes were destroyed (Teodorowicz et al., 2014). However the neotype designation by Teodorowicz et al (2014) is not valid, because it does not satisfy Articles 75.1 and 75.3 of the International Code of Zoological Nomenclature (ICZN, 1999).
In one of the female specimens that we examined, an unpaired seta x was present between setae j5–j5 (Fig. 3). Otherwise, our observation of the species essentially agrees with the re-description given by Teodorowicz et al. (2014). This species most resembles A. (V.) koroljevae Chelebiev, 1984, for which we have studied detailed photos of one female from the type series on the slide (No. 1792) deposited at the Zoological Institute of the Russian Academy of Science, Saint Petersburg, Russia. Antennoseius (V.) oudemansi is distinguished from A. (V.) koroljevae and all other species of subgenus Vitzthumia Thor, 1930 by following combination of characters: (1) dorsal shields having a reticulate pattern of tubercles superimposed on granulate-tuberculate surface (Figs 3 & 4) (in the examined specimen of A. (V.) koroljevae, the dorsal shield is finely granulate-tuberculate), podonotal shield with 19–20 pairs of setae, including one or two pairs of sx setae between s2 and s4 setae and all marginal r -series off the shield (Figs 3 & 4) (in examined specimen of A. (V.) koroljevae, podonotal shield with 20 pairs of setae including one pair of sx setae and with only r4 of marginal series on edge of shield, four unpaired seta x were present between setae j3–j5), almost all podonotal setae barbed, setae j1 leaf-like, wider than other dorsal setae (see Fig. 3), opisthonotal shield with 12–15 pairs of setae, all slightly barbed and R1 on the lateral soft cuticle (Fig. 3) (in examined specimen of A. (V.) koroljevae, opisthonotal shield with 17 pairs of setae), sternal shield roundly incised anteromedially (Fig. 5), epistome arc-shaped and irregularly denticulate (Fig. 6), all palp setae smooth and needle-like except d1 on palpfemur with some barbs (Fig. 7), palp-tarsal claw two-tined (Fig. 7), hypostomal groove with seven rows of denticles (Fig. 8), fixed digit of chelicera multidentate (Fig. 9) and almost all dorsal leg setae barbed (Fig. 10).
