Roma Province, Lazio, Italy): 63) wings, 64) ovipositor, 65) metatibia and metatarsus.

DIAGNOSIS. FEMALE (specimens from the European part of Russia, Belgium and

Italy). Body length (slide-mounted specimens) 0.8–0.86 mm. Antenna ( Figs 61, 62 ) with scape (excluding radicle) 2.8–3.4× as long as wide, with faint, inconspicuous cross-ridges;

F2–F6 longer than pedicel, F2 3.8–4.5× as long as wide (2.9 in one tentatively identified,

small specimen), F3 the longest funicular, F2 without mps, F3–F6 each with 2 mps; clava with 6 mps, 2.5–3.2× as long as wide, 0.8–0.9× as long as combined length of F5 and F6.

Fore wing ( Fig. 63 ) 4.9–5.4× as long as wide; longest marginal seta 0.9–1.0× maximum wing width; marginal space separated from medial space by 1 complete line of setae. Hind wing

( Fig. 63 ) 18–22× as long as wide; longest marginal seta 3.1–3.6× maximum wing width, disc with 1 irregular row of setae apically. Metatarsomere 1 either about as long as or slightly shorter than metatarsomere 2 ( Fig. 65 ). Ovipositor ( Fig. 64 ) occupying entire length of gaster, extending forward at most to base of mesocoxa, not or at most barely exserted beyond apex of gaster posteriorly, and 1.1–1.5× length of metatibia.

MALE. Known (Huber & Thuróczy, 2018).

DISTRIBUTION. Russia *; Austria, Belgium (Debauche 1948 [as A. (Anaphes) fuscipennis , females only]; Huber, 1992), Germany, Italy *, Poland, Switzerland.

HOST. Miridae (Hemiptera) : Lygus rugulipennis Poppius, 1911 (Huber & Thuróczy,

2018).

REMARKS. The following specimens also likely belong to A. (Anaphes) medius : China:

Beijing, Mentougou District, Liyan Ling, Linshan Mts. , 40°00.28’N 115°30.75’E, 1749 m ,

2.VIII 2002 (G. Melika) [1 ♀, UCRC]. Russia: Moskovskaya oblast’, Noginskiy rayon ,

Fryazevo, 14.VII 2002 (M.E. Tretiakov) [1 ♀, UCRC] .

Anaphes (Anaphes) medius can be easily confused with A. (Anaphes) regulus Walker,

1846 when the key in Huber & Thuróczy (2018) is used, which separates them very narrowly based on the length of the ovipositor sheaths (not of the ovipositor itself) relative to the metatibia length. Thus, any clearcut separation of these two nominal species is practically impossible by the relative length of the ovipositor (I also have seen female specimens from

Finland, to be reported elsewhere, that seem to belong to A. (Anaphes) regulus but whose ovipositor is about 1.1× length of the metatibia), but it appears that in A. (Anaphes) medius the clava is relatively shorter (slightly shorter than the combined length of F5 and F6) than in

A. (Anaphes) regulus (at least slightly longer than the combined length of F5 and F6). Indeed,

in both the lectotype (fig. 85, p. 94 in Huber & Thuróczy, 2018) and the paralectotype (fig. 4, p.

56 in Thuróczy & O’Connor, 2015) females of A. regulus the clava is distinctly longer than the combined length of F5 and F6. Females of both species also separate well by the length to width ratio of the fore wing, as indicated in the key.
