Transeius fragilis (Kolodochka & Bondarenko) Amblyseius fragilis Kolodochka & Bondarenko 1993: 34. Typhlodromips fragilis, Moraes et al. 2004: 213. Transeius fragilis, Chant & McMurtry 2004a: 187; 2007: 71. This species belongs to the bellottii species group as seta z4 is not as long as 2/3 distance between its base and that of seta s4. The spermatheca has the calyx bell-shaped and that keys to bellottii species subgroup. This species was described by Kolodochka and Bodarenko (1993) with specimens collected in the Black Sea National Biosphere Reserve, Solenoozernyy, Kherson Region, Ukraine, on Taraxacum sp. for the holotype and on Frankenia hirsuta L. and Cirsium sp. for the paratypes. The biology of that species is totally unknown. This is the first report of that species from Slovenia. World distribution: Ukraine. Specimens examined: 3 ♀♀ in total. Podgorje (aasl 228 m, lat. 46°42’18”N, long. 15°49’13”E), 1 ♀ on Phaseolus vulgaris L. (Fabaceae) and 2 ♀♀ on Fragaria sp. (Rosaceae), 12/VII/2018. Remarks: The measurements of the three adult females (Table 2) collected agree quite well with those provided by Kolodochka and Bodarenko (1993) for specimens collected on diverse plant species from Ukraine, with only slightly longer setae z4 and S2, and slightly shorter macrosetae of the leg IV in the Slovenian specimens.
