Deposition material. From the sample from the Botanical Garden of Yakutsk (coll. date 27.07.2016; 19.07.2017) 3♀ and 2♂ are preserved in the collection of the Netherlands Institute for Vectors, Invasive plants and Plant health at Wageningen. All other material is added to the collection of IBPC SB RAS — 16♀, 3♂.

DISTRIBUTION. NE China: Heilongjiang province; Russia: E Siberia: C, W, N-E, N Yakutia, W Siberia: Novosibirsk region (Fig. 1).

DESCIPTION. Female (micropterous). Body length 1.4– 1.5 mm. Head length 90, width 107; antenna length 237.

Body brown, legs brown, with distal half of tibia and tarsi yellow (Fig. 2) or legs almost completely yellow; antennae 9- segmented, I light brown or brown, II and VI –IX brown III and IV light brown; V brown, with extreme base yellow (Figs 3–4), segment VI with an incomplete oblique suture; segments III– IV with small forked sensorium and rows of microtrichia.

Head slightly wider than long; ocelli reduced or absent, three pairs of ocellar setae; dorsal surface with transverse reticulations (Fig. 5).

Pronotum smooth, without long setae (Fig. 5). Mesonotum with transverse reticulations, and a pair of campaniform sensilla close to anterior margin. Metanotum with polygonal reticulations, a pair of anterosubmarginal setae and, a pair of median setae variously located in a region one third to two thirds separated from the anterior margin, a pair of campaniform sensilla in the posterior third (Figs 6–9), metascutellum partly separated from the metascutum (Figs 6–7) or metascutellum completely fused, and often indistinguishable (Figs 8–9); mesofurca with spinula, metafurca without spinula. Fore wings reduced to small scales (Figs 5–8) (see note below), axillary sclerites present.

Abdominal tergites II –VIII with sculpture laterally, with a pair of median setae and two pairs of campaniform sensilla; tergite VIII posteromarginally with a complete craspedum formed of small teeth shaped pointed lobes, which little increase in size to both sides (Fig. 10); tergite IX with a pair of mid-dorsal setae and two pairs of campaniform sensilla, with S1 and S2 located to posterior margin and slightly longer than tergite X; tergite X with a pair of campaniform sensilla and two pair of long setae close to posterior margin. Sternites II –VII reticulated laterally, without discal setae.

Male (micropterous): body yellow length 0.9–1.1 mm, antennal segment I– V completely yellow, except V, which has apical fourth brown, VI –IX completely brown; sternites III– VI with C-shaped pore plate, on VII boomerang or oval shaped (Figs 11–12); tergite VIII with craspedial lobes sometimes medially absent; tergite IX with two pairs of stout median setae (Fig. 13).

NOTE. In Cui et al. [2017] both sexes of Anaphothrips dentatus are described to be apterous, but in fact both sexes are micropterous; in figure 7 of their publication wing pads with axillary sclerites are visible.
