Ortheziola mizushimai Tanaka & Amano , n. sp. ( Fig.1 )

Type material. HOLOTYPE, adult female: Japan, Mt. Hasuge, Aikawa-chô, Kanagawa-pref., 27- -2004, coll. H. Mizushima ( NSMT). PARATYPE: adult female: data as for holotype (TUA). Other material (not paratype): data as for holotype, one adult female in poor condition (TUA).

Description (adult female, holotype and a paratype) ( Fig. 1 ).

Mounted material. 1.2–1.3 mm long and 0.9–1.0 mm wide. Antennae: segment I 82 –107 Μm long, 74–86 Μm wide; II 52 –67 Μm long, 37–42 Μm wide; III 268–289 Μm long, 32–42 Μm wide; segment III nearly parallel sided; apical seta 132–134 Μm long, subapical seta 44–52 Μm long; flagellate sensory seta near apical seta 27–28 Μm long; unusual hair-like seta absent from near subapical seta; all segments covered with spine-like setae; segment I with 0–3 clavate sensory setae on each side of segment; segment III with 42–51 spine-like setae.

Ve n te r. Labium 83–148 Μm long. Stylet loop longer than labium. Legs (lengths in Μm): anterior legs: coxa 123–134, trochanter-femur 315–338, tibia + tarsus 302–334, claw 31–42; claw digitules each about 15 Μm long; middle legs: coxae 118–158, trochanter–femur 318–328, tibia + tarsus 325–348, claw 37–49; claw digitules each about 15 Μm long; posterior legs: coxae 142–151, trochanter-femur 376–402, tibia + tarsus 386– 433, claw 48–54: claw digitules each 13–18 Μm long. Claws without a denticle. All legs with rows of robust setae; also with 1 or 2 flagellate setae present on distal end of trochanter-femur. Wax plates absent from marginal areas of head and thorax; marginal wax band surrounding each thoracic spiracle (plates 15 and 16) present; with one band of spines present within ovisac band. Each thoracic spiraclular opening with a scattered group of 5-9 disc pores, each with 5 or 6 loculi; diameter of anterior thoracic spiraclular peritremes 23– 27 Μm. Setose setae scattered medially on thorax, although a few clavate around mouthparts and on abdomen. Multilocular pores, each with 6–8 loculi, present along anterior margin of ovisac band, along posterior edges of ovisac band, and also along anterior margin and inside of spine band within ovisac. Pores absent from around vulva. Abdominal spiracles not detected.

Dorsum. Wax plates covering two–thirds of dorsal surface; wax plates 3, 5 & 6 present, covering most of mediolateral areas of thorax; wax plates absent medially on thorax and abdomen; wax plate 3 divided medially; wax plate 7 separated into several subplates posteriorly. With a few setae present mainly on medial area and with a few setae clavate. Disc pores, each with 4–6 loculi, present on posterolateral area of wax plate 7. Sclerotized anal plate in front of anal ring 24–48 Μm long, 222–242 Μm wide. Anal ring with incomplete twin–triple rows of round pores; longest anal ring seta 58 Μm, longer than length of anal ring; anal ring 42–44 Μm wide, 49 Μm long. With a group of disc pores, each with 5–8 loculi, present on each side of anal ring.

Host. Unknown. Type series extracted with Berlese funnels from forest litter.

Etymology. This species is dedicated to Mr. Hiroki Mizushima, who collected the specimens.

Remarks. O. mizushimai resembles Ortheziola peregovitsi Kozár et Konczné Benedicty (2001) in having wax plate 3 present and in lacking multilocular disc pores around the vulva. However, it differs from O. peregovitsi in having: (i) disc pores with 5 or 6 loculi around each thoracic spiracle; (ii) fewer clavate setae on both of median dorsal surface and ventral median area, and (iii) wax plate 7 clearly separated into several subplates posteriorly ( O. peregovitsi has disc pores with only 4 loculi around each spiracle and the separation of wax plate 7 into subplates is indistinct).
