Description (adult female, holotype only) (Fig. 2).

Mounted material. 1.9 mm long and 1.3 mm wide. Antennae: segment I 104–107 Μm long, 100–102 Μm wide; II 56 –60 Μm long, 68–70 Μm wide; III 390–398 Μm long, 75–82 Μm wide; segment III nearly parallel sided; apical seta of antenna 149 Μm long, subapical seta 59 Μm long; flagellate sensory seta near apical seta 24–30 Μm long; microseta absent from apex of antenna; unusual hair-like seta absent from near subapical seta; all segments covered with hair-like setae; segment I with 1 clavate sensory seta on each side of segment.

Ve n te r. Labium 144 Μm long. Stylet loop longer than labium. Legs (lengths in Μm): anterior legs: coxae 137–142, trochanter-femur 426–452, tibia + tarsus 438–472, claw 56–69; claw digitules each 19–23 Μm long; middle legs: coxae 126–144, trochanter-femur 446–447, tibia + tarsus 460–486, claw 66–68; claw digitules each 23–24 Μm long; posterior legs: coxae 182, trochanter-femur 517. Left posterior leg plus tibia, tarsus and claw of right posterior leg missing. Claws without a denticle. All legs with rows of robust setae. Wax plates present on marginal areas of head and thorax; with a wide marginal wax band surrounding each thoracic spiracle (plates 15 and 16); with large rectangular-shaped wax plates surrounding each coxa present; cluster of spines band between hind legs and ovisac band present; with two bands of spines present within ovisac band. With a few setose setae scattered medially on thorax. Multilocular pores, each with 10–13 loculi, present anterior to posterior edges of ovisac band, and also around vulva; quadrilocular pores present along margins of spine bands inside ovisac area. Abdominal spiracles not detected.

Dorsum. Wax plates present, covering all of dorsal surface; wax plates 3, 5, 6, 8, 9, and 10 present; wax plates 9 and 10 wide; plate 9 almost an equilateral triangle. In shape; wax plate 10 narrow posteriorly, widening significantly near anterior margin. Sclerotized anal plate in front of anal ring 68 Μm long, 202 Μm wide. Anal ring with 6 setae; longest seta 48 Μm; anal ring 48Μm wide. With a group of disc pores, each with 8 loculi, present around anal ring.

Host. Unknown. Type specimen and other examined specimens extracted by Berlese funnels from forest litter.

Etymology. This species is dedicated to Mr. Satoshi Maehara, one of the collectors of the specimens.

Remarks. Om. maeharai resembles the Nepalese species Ortheziolamameti loebli (Richard) (1990) and the Taiwanese species Om. taipensiana Shiau & Kozár (2004) in having hair-like rather than spine-like setae on the antennae. However, it differs from Om. loebli in having multilocular pores around the vulva; and from Om. taipensiana in the shape of wax plates 9 and 10, with wax plate 9 being very broad and almost an equilateral triangle in shape, and wax plate 10 being rather narrow posteriorly and along most of its length but then widening suddenly near anterior margin (wax plate 9 on Om. taipensiana is narrow and elongated, in the shape of an isosceles triangle, while wax plate 10 widens gradually from posterior to anterior margin, not widening abruptly near anterior margin).
