 Amblyseius (Neoseiulus) alustoni Karg, 1993: 188.   
 Neoseiulus alustoni: Kolodochka, 2004: 300, 2006: 231; Döker et al., 2016: 513.   
 Material. Type. Syntypes 2 ♀: Ukraine, AR Crimea, Yalta, Nikitsky State Botanical Garden, Avena ludoviciana, [No. of the slide unknown], 21.06.1968 (Kuznetzov) (SNBG).   
 Non-type. Ukraine: Crimea, Karadag, plateau on the south-southwest slope of the Mount Karagach, env. of Biological Station, on Pistacea vera, specimen #1382, 11.06.1975, 1 ♀ (Kolodochka); idem, on Pyrus elaegnifolia, specimen #1388a, 13.06.1975, 1 ♀ (Kolodochka).   
 Female. Dorsal shield (fig. 3, 1) moderately sclerotized, oval; 4 pairs of small solenostomes (it, id, il, ic; missing iv, isc, is). Dorsal setae bristle-shaped, moderately long, smooth, except for slightly serrated PM 3 and PM 4. Setae PM 4 are the longest. Peritremes reach level of setae AM 1, which slightly extend beyond AL 1 theca. Seta AL 1 somewhat shorter than AL 3 which does not reach the theca AL 4. Setae in rows AL and PL are shorter than the distance to the next setae. Seta PM 1 almost reaching the theca PL 1, which is longer than PL 2 and PL 3. Ventrianal shield elongated, with convex lateral margins, transversely striated (fig. 3, 2); anal pores distinct, small, round, slightly contiguous. Anterior metapodal shield small and narrow; posterior metapodal shield 3.5 times as long as the anterior one, narrow, curved (fig. 3, 3). On Df 3 closely spaced distal teeth, Dm has 2 widely spaced teeth: distal and basal (the latter located at the base of finger) (fig. 3, 4). Spermatheca funnel with thickened walls, bell-shaped; atrium large, sessile (fig. 3, 5). Posterior end of peritremal shield is narrow, curved, pointed, with a pore at end (fig. 3, 6). There are three pointed macrosetae on leg of pair IV: the longest one on basitarsus, on genu and tibia along a short macroseta of equal length (fig. 3, 7). Other legs without macrosetae.   
Measurements: Lds 340, Wds 185; Lvas 117, Wvas 97, Lian 29; Ltar 103. Setae length: AD1 19, AD2 17, AD3 20, AD4 26, PD 2 28; PD 4 12, AM 1 30, АМ2 19; АL 1 28; АL 3 30, АL 4 45, РL1 45; РL2 36; PL 3 17; PM 1 33; РМ3 55; РМ4 78; АS 30, РS 23; РV 60; MСh IV: ge 26, ti 25, ta 68.
