Yamatentomon brevisetum Szeptycki & Imadaté, 1987 Figs. 11–12 Yamatentomon breviseta [sic] Szeptycki & Imadaté, 1987, pp. 172–176, figs. 11–17. Yamatentomon brevisetum, Szeptycki, 2007, p. 97. Material examined. Holotype female (NSMT-Ap 108), Kymgang-san Mts., Ou-Kymgang, Korea, pine forest with very rich undergrowth, 30-VI-1981, Szeptycki & Weiner leg. Diagnosis. Cephalic additional setae d6 absent; anterior setae A1 absent, A4' present on tergite VII; posterior accessory setae on tergites II–VI short, sensilliform, about one-seventh of P 1 in length; P1a' present on tergite VI. Supplementary notes on description. Cephalic setae l3, sd4, and sd5 setiform, l3 9 μm long, sd4 and sd5, 13 μm; additional setae d6 absent (Fig. 11A); seta d7 and sd7 subequal in length, 24 μm; pores fp and cp present (Fig. 11A); sensilla on maxillary palpus similar in length, 8 μm; dorsal sensillum slender (Fig. 11B), ventral one broadened proximally (Fig. 11C); praelabium with fringe at anterior part, labial palpus with slender sensillum (Fig. 11D). Length of pronotal setae 1 36 μm, about 1.3 times longer than setae 2, 28 μm. Foretarsal setae β1 and δ4 long, setiform; β1 length 20 μm, 1.3 times longer than δ1; δ4 long 28 μm, about twice the length of δ1; δ1–δ3 and δ5 short, setiform, 15–16 μm; pores present near sensilla c and t3, respectively (Fig. 11E). Sternite II with three anterior setae (Ac and A2) and five posterior setae (Fig. 12E). Mesonotum with pores al and sl (Fig. 12A); metanotum with sl (Fig. 12A); prosternum without pores; mesosternum and metasternum with a group of three adjacent sc (Fig. 12D). Tergite I with pore spm; II–VI with spm and al (Fig. 12B, H); VII with spm, psl and al (Fig. 12C). Sternites I, II, IV, and V with single spm (Fig. 12E, G); III with a pair of spsm (Fig. 12F); VI–VII with a pair of spsm and a group of adjacent three sam pores on or near connecting line (Fig. 12H, I). Abdominal segment XII with dorsal central pore and a pair of ventral anterolateral pores (Fig. 12J, K). Central part of ventral hind margin of XII with fine teeth (Fig. 12K). Notes. Szeptycki & Imadaté (1987) described the chaetotaxy of sternite II as having five anterior setae (Ac, A2, A3); however, this examination revealed that there are just three anterior setae (Ac, A2) (Fig. 12E). Distribution. North Korea (Kymgang-san Mts.), known only from the type locality.
