Komaga –take, Kanegasaki –machi, Iwate Prefecture, 39º11'21"N, 140º55'41"E, 820 m elevation, litter of a forest dominated by <i>F. crenata</i>, 18-VIII-2001, H. Tamura <i>et al.</i> leg. Paratype: one female (NSMT –Ap 511), same data as for the holotype. <b>Other specimens examined.</b> One female, Ogamido, Shimokimita, Takahagi–shi, Ibaraki Prefecture, 36º48'33"N, 140º35'20"E, 540 m elevation, litter of a deciduous broad-leaved forest, 3- VII- 1988, H. Tamura <i>et al.</i> leg.; 1 female, Miyanozawa, Kamikimita, Takahagi–shi, Ibaraki Prefecture, 36º47'49"N, 140º34'38"E, 500 m elevation, litter of a forest dominated by <i>F. crenata</i> and <i>Q. crispula</i>, 26-VI-1989, K. Ishii &amp; H. Sakayori leg.; 1 female, Kameyachi, Sekimoto–cho, Kitaibaraki–shi, Ibaraki Prefecture, 36º54'01"N, 140°37'08"E, 780 m elevation, litter of a forest dominated by <i>Q. serrata</i> and <i>Q. crispula</i>, 15-VI-2001, H. Sakayori <i>et al.</i> leg. <b>Description.</b> Body length 592 (598) µm. Head 86 (87) µm long, 60 (52) µm wide. Setae <i>pa</i> and <i>m4</i> present, but seta <i>aa</i> absent (Fig. 44A), sensilla <i>as</i> and <i>ps</i> present; seta <i>sp</i> 1.2 times longer than <i>p</i>; sensilla <i>pp</i> rudimentary. Labral setae absent (Fig. 44B). Seta <i>rs</i> simple, slightly longer than <i>sr</i> (Fig. 44B). On maxillary palpus (Fig. 44C) sensillum <i>md</i> slightly longer than <i>ml</i>. Digits on galea small and similar to each other (Fig. 44D). Mandible with two teeth (Fig. 44E). Clypeal apodemes distinct (Figs. 44A, B). Pseudoculus 8 µm long, without inner structure (Fig. 44F), PR = 11. Foretarsus length (Figs. 44G, H) 58 (58) µm; claw 14 (13) µm, TR = 4.2 (4.4); empodium 15 µm, EU = 1.0; sensillum <i>s</i> longer than claw, 16 (14) µm. Sensillum <i>t1</i> nearer to α <i>3</i> than to α <i>3’</i>, BS = 0.8 (0.8); <i>t2</i> thinly spatulate; <i>t3</i> surpassing base of α <i>7</i>; <i>a</i> reaching nearly to base of γ <i>2</i>; <i>b</i> reaching base of β <i>6</i>; <i>c</i> linear; <i>d</i> not reaching base of α <i>5</i>; <i>e</i> and <i>g</i> spatulate and long; <i>f1</i> thinly spatulate; <i>f2</i> thin; <i>a'</i> at same level with α <i>3</i>; <i>b'1</i> absent; <i>b'2</i> as long as <i>d</i>; <i>c'</i> not reaching base of δ <i>6</i>. Length of middle tarsus 28 (28) µm, length of claw 10 (9) µm; hind tarsus 36 (36) µm, claw 11 (10) µm; empodia of both tarsi short and less than 1/6 of claw length, 1 (1) µm long; on hind tarsus (Fig. 44I) <i>D2</i> seta-like; <i>D4</i> spine-like. Tracheal camerae slender (Fig. 44J). Central lobe sinuate, inner lines incised (Fig. 44K). Laterostigmata II–IV large, with no inner structure; those on V–VI small. On female squama genitalis (Fig. 44L) processus sternalis serpentiform as a winding rope, caput processus smoothly curved towards a median of stylus, filum processus short. Male unknown. Chaetotaxy as in Table 18. On thoracic tergites II–III, <i>P1a</i> and <i>P2a</i> seta-like; <i>P1a</i> posterior to <i>P1–P2</i>, at halfway between <i>P1</i> and <i>P2</i> or slightly nearer to <i>P2</i> than to <i>P1</i>. <i>P1a</i> on abdominal tergite I, <i>P1a</i> and <i>P2a</i> on II–VI and <i>P2a</i> on VII filiform and longer than <i>P1</i>; <i>P1a</i> on VII sensillum-like and less than one-third length of <i>P1</i>, 5 µm long, posterior to <i>P1–P2</i> (Fig. 44M); on tergite VIII (Fig. 44N) <i>P1a’</i> without basal dilatation and anterior to <i>P2</i>, <i>P2a</i> linear. <b>Diagnosis.</b> The present species resembles <i>E. topochi</i> Imadaté from Japan (Imadaté, 1964a, 1974b, 1995) in the body chaetotaxy and the position of foretarsal sensilla, but it is distinguished from the latter in the absence of labral setae (present in <i>E. topochi</i>), and on the forestarsus, sensillum <i>a</i> not reaching the base of γ <i>2</i> (surpassing the base of γ <i>2</i> in <i>E. topochi</i>), <i>t3</i> longer than <i>c’</i> (shorter than <i>c'</i> in <i>E. topochi</i>), and <i>t2</i> and <i>f1</i> spatulate (linear in <i>E. topochi</i>). In the key of Yin (1999) this new species tends to run to <i>E. yilingense</i> Yin &amp; Zhang from China (Yin, 1999; Yin &amp; Zhang, 1982), but differs by the absence of labral setae (present in <i>E. yilingense</i>), the position of <i>P1a</i> posterior to <i>P1–P2</i> on the abdominal tergite VII (at same level with <i>P1–P 2</i> in <i>E. yilingense</i>) and the short empodium of the hind tarsus (long in <i>E. yilingense</i>). <b>Etymology.</b> The specific name is named in honor of "More", who was a clever sub-leader of the tribe Emishi, which occupied the area called Hitakami 1200 years ago, which includes the type locality of the present new species. <b>Distribution.</b> Japan (Honshu).
