(Figures 1–9)
Type material. Holotype ♀ (ZDAMU, registration No. HYM.CH.826), on slide under 4 coverslips, slide No. MYM.904, labelled: “ INDIA. ODISHA: Jharsuguda, Sarbahal, 15.xii.2007, Coll. F.R. Khan.
Paratypes, 4 ♀. INDIA. KERALA: Alappuzha, Kuetallthakall, 16.i.2012, (1 ♀, on slide under 4 coverslips, slide No. MYM.121, ZDAMU); Kyamkulam, 17.i.2012, Coll. F.R. Khan (2 ♀, on slides under 4, 5 coverslips, slide Nos. MYM.140, MYM.141, ZDAMU). ODISHA: Bhubaneshwar, OUAT, 20.i.2012, YPT, Coll. K. Veenakumari (1 ♀, on slide under 4 coverslips, slide No. MYM.903, NBAIR).
Diagnosis. With the following combination of features: antenna (Fig. 2) with fl 4 shorter than fl 3 or fl 5; fl 1, fl 2 and fl 4 without mps, and fl 3, fl 5 and fl 6 with two mps each; clava two-segmented, slightly longer than fl 5 and fl 6 combined; occipital groove short and angled medially towards foramen (Fig. 4, arrows); second phragma apically with a distinct notch (Fig. 8); fore wing with a wide gap between hypochaeta and base of subcubital setal line (Fig. 5, arrows), and disc with relatively few microtrichiae, not uniformly distributed in rows except cubital setal line; ovipositor extending well forward under metasoma, about up to level of midpoint of mesoscutum, with dorsal and ventral arms very close together or in contact with each other (Figs 7, 9).
Based on the shared feature of the occipital groove [incorrectly labelled vertexal suture in Huber & Thuróczy (2018)], that is angled inwardly toward dorsolateral angle of the foramen (Fig. 4, arrows) this species is in the same species group as A. collinus Walker from Europe and North America, A. brevis Walker from Europe, A. conotracheli Girault from North America, and at least three Australian species: A. inexpectatus Huber & Prinsloo (Australia, introduced into Europe), A. nitens (Girault), and A. tasmaniae Huber & Prinsloo. Two others, A. galtoni (Girault) and A. australia (Girault) may also belong to this species group but the direction and length of the occipital groove cannot be determined on the uncleared and crushed heads of the type specimens (Figs 21, 23). However, their relatively hyaline fore wings with the narrowly dark edge of the anterior margin contrasting with the hyaline edge of the posterior margin strongly suggests they belong to the collinus species group. In A. triapitsyni fl 4 lacks mps, similar to A. galtoni (Fig. 23) and A. collinus but unlike the remaining described Australian species, all of which have mps on fl 4 (Figs 25, 27 and figs 7–9 in Huber & Prinsloo (1990)). The rather sparse discal microtrichia and distinct gap between base of subcubital row and hypochaeta (Fig. 5) are unique to A. triapitsyni and distinguish it from other described Anaphes species.
Description. FEMALE. Holotype body length 450 µm (paratypes 370–386 µm, card mounted specimens measured before slide mounting). Body dark brown. Antenna brown. Legs pale brown. Fore wing subhyaline. Head. 1.26× (paratypes 1.16–1.27×) as broad as high (Fig. 3). Occiput with very short and dorsolateral angled groove directed medially towards occipital foramen (Fig. 4). Antenna. fl 4 shorter than fl 3 or fl 5; fl 1, fl 2 and fl 4 without mps, fl 3, fl 5 and fl 6 each with two mps (Fig. 2); clava 2-segmented, shorter than fl 4 –fl 6 combined, 3.8× (paratypes 2.7–3.3×) as long as broad, with 6 mps. Mesosoma. Mesoscutal midlobe with setae fairly short and near posterior margin; axillar setae short; second phragma with a fairly deep median notch (Fig. 8). Wings. Fore wing 5.1× (paratypes 5.1–5.8×) as long as broad, with a wide gap between hypochaeta and base of cubital row of microtrichia, the cubital row somewhat sinuate, paralleling posterior margin of wing but, not extending to wing apex; wing disc otherwise with microtrichia scattered unevenly leaving much of disc bare (Fig. 5); longest marginal seta 1.25× (paratypes 1.42–1.56×) maximum wing width. Hind wing 21× (paratypes 21.2–22.5×) as long as broad, without microtrichiae on surface between the usual anterior and posterior rows (Fig. 6); longest marginal seta 4.4× (paratypes 5.0×) maximum wing width. Legs. Metatarsomere 1 0.91× (paratypes 0.8–0.9×) as long as metatarsomere 2 (Fig. 7). Metasoma. Ovipositor 1.5× (paratypes 1.9×) as long as metatibia length, and extending forward under metasoma up to level of midpoint of mesoscutum (Figs 7, 9). Measurements (n=4) head width/height, 175–190/138–150; antennal segments length/width: radicle, 15–18/10–13; scape, 18–23/43–55; pedicel, 30–35/25–28; fl 1, 18–20/13; fl 2, 30–33/10–13; fl 3, 45–48/15–20; fl 4, 33–35/15–18; fl 5, 45–48/18–20; fl 6, 45/20–23; clava, 88–98/25–33; mesosoma length, 208–238; fore wing length/width, 450–510/88–100; longest marginal seta, 125; hind wing length/width, 425–475/20–23; longest marginal seta, 88–115; metatibia length, 150–163; metatarsus 1, 20–28; metatarsus 2, 25–30; gaster length, 200–238; ovipositor length, 360–375.
