Peloribates pilosus Hammer, 1952

( Figures 15 & 16 )

Measurements. Body length: 506 μm, width of notogaster 394 μm, length of notogaster 407 μm.

Supplementary description. Body colour reddish brown; body surface foveolate. Rostrum slightly projected in lateral view, but rounded in dorsal view. Rostral seta 71 μm long, barbed. Lamellae relatively wide, but distinctly narrowed distally. Lamellar seta 105 μm long, barbed, inserted at distal end of lamella. Tutorium moderately long, narrow, slightly widening anteriorly, seta ro inserted at its distal end. Interlamellar seta 126 μm long, barbed. Bothridium directed anterolaterad, with small opening; bothridial seta 71 μm long, with minutely barbed clavate head. Notogaster almost circular, anterior margin broadly rounded. Pteromorpha fully hinged, slightly curved downwards; notogastral setae 63–84 μm long, all barbed. Sacculi small, round in shape. Lyrifissures ia, im and ih well developed; other lyrifissures and opisthonotal gland opening not evident. Subcapitular mentum wider than long, hypostomal setae a 21 μm long, m 34 μm long, h 42 μm long, all thin, smooth. Chelicera and palp typical for genus; palpal setation: 0–2–1–3–9(+ω). Epimeral region nearly smooth, apodemes apo.2, apo.sj and apo.3 aligned obliquely. Epimeral setae 25–29 μm long, thin, smooth, setal formula: 3–1–3–3. Circumpedal carina long, discidium projected laterally. Five pairs of genital setae 21–25 μm long, one pair of aggenital setae 12 μm long, two pairs of anal setae 25–29 μm long, three pairs of adanal setae 29–34 μm long, all setae barbed. Adanal lyrifissure iad situated adjacent and parallel to lateral margin of anal aperture. Legs heterotridactylous, setation of legs typical for genus, formula of leg setation including famulus: I (1–5–3–4–21); II (1–5–3–4–15); III (1–3–1–3–14); IV (1–2–2–2–12) and formula of solenidia: I (1–2–2); II (1–1–2); III (1–1–0); IV (0–1–0).

Distribution. Holarctic region.

Material examined. One female: Pachong, Daegu, Gyeongsangbuk-do, under broad-leaved trees, 15 October 2022, Coll. Y.S. Bae.

Remarks. The character states of the present material accord well with those of the specimens studied by Hammer (1952) and Walter et al. (2014).
