Material. Type. Holotype} Typhlodromus aberrans : The Netherlands, Arnhem, on Tilia platiphillos , #376 [collection date unknown] ( RMNH).

Non-type. 5078 specimens (3941}, 1137 {) — throughout Ukraine.

R e d e s c r i p t i o n. F e m a l e. Dorsal shield ( fig. 3 , 1 ) weakly sclerotised, elongate-oval, with lateral notches, covered with reticulate-scaly sculpture with slight folding; 4 pairs of small solenostomes (it, iv, il, ic; id, isc, ic are absent). Setae AD 1, AM 1, AL 1, AL 3, AL 4, PL 1, PM 3, PM 4, AS, PS serrated, elongated, others smooth and much shorter. Setae AD 3 as long as distance between their thecae. Setae AM 1 and AL 1 extend beyond the thecae of subsequent setae. Peritremes reach the level of thecae setae AL 1. Sternal shield with deep notch along posterior margin. Ventrianal shield ( fig. 3 , 2 ) elongate, narrow, with distinct lateral emarginations, its anterior part wider than posterior, preanal setae arranged in two almost longitudinal rows; anal pores small, widely spaced, poorly distinguishable. Setae PV serrated. Metapodal scutes linear, posterior S-shaped, 3 times as long as anterior ( fig. 3, 3 ). Posterior part of peritremal shield slightly curved ( fig. 3 , 4 ). Chelicera with 2 teeth on Df, Dm with 1 tooth ( fig. 3 , 5 ). Spermatheca is small, the funnel is saucer-shaped; atrium of moderate size, sessile ( fig. 3 , 6 ). There are no macrochaetes on the legs ( fig. 3 , 7 ).

Measurements. Lds 305, Wds 150; Lvas 95, Wvas 75, Lian 25; Ltar 92; setae length: AD 1 19; AD 2 18; AD 3 15; AD 4 16; PD 2 22; PD 4 8; AM 1 39; AM 2 14; AL 1 33; AL 3 45; AL 4 58; PL 1 56; PL 3 14; PM 1 19; PM 3 53; PM 4 58; AS 45; PS 28; PV 30.

Male. Ventrianal shield with 3 pairs of preanal setae, anal pores small ( fig. 3 , 8 ); spermatodactyl massive, beak-shaped ( fig. 3 , 9 ). Lds 240.

Diagnosis. There is considerable variation in the indicators of metric characters in different populations of K. aberrans , which is widespread in countries with a temperate climate ( Chant, 1955). This reduces the diagnostic power of metric characters in describing species differences, especially when comparing closely related species. Therefore, metric characters have not been used here to describe differences between K. aberrans and other species of the genus. In addition to the characters indicated in the key for species of the genus (see above), K. aberrans has other morphological characters that are absent in Kampimodromus species known in Ukraine, namely, macrochaetae on the legs do not differ from ordinary setae, anal pores are small and widely spaced, the other shape and structure of the relatively more massive male spermatodactyl is different.

D i s t r i b u t i o n, h a b i t a t, o c c u r r e n c e. The species is widespread in Europe, the Middle East, and the Caucasus. In Ukraine: in natural and cultivated plantations in all natural zones. Prefers woody and shrubby plants of Rosaceae , which are often numerous; common in abandoned fruit orchards, found in industrial vineyards, garden plots, occasionally on herbaceous annuals and perennials of other families; mass.

Notes. 1. Description, morphometry, and illustrations are based on non-type specimens from Kyiv.

2. The author’s own observations confirm evidence from various sources of nondiscrete (monotonic) variability in length of dorsal setae that often observed in mites of various populations of K. aberrans . It was also established that serration of dorsal setae depends on their own length and thickness (shorter setae usually are smoother).
