Type material. Holotype: female, 21 mm long, subadult ( Bonato et al., 2002).

Type locality. ‘Gushikawa­son, Kume Island’, Ryukyu Ids ( Bonato et al., 2002).

Depository of type material. National Science Museum , Tokyo ( Bonato et al., 2002) .

Material examined. 1 specimen: female, subadult (21 mm), from Gushikawa­son, Kume Id., Okinawa Pref., Ryukyu Ids , 23.II.1992, T. Tanabe leg. , coll. NSMT (holotype) .

Description. Body size reaching at least about 2 cm. Body colour yellow, without dark patches; head and forcipular segment orange. Head 1.6 times as long as wide, frontal line indistinct. Antennae 3.6 times as long as the head width; apical sensilla about 10 µm long. Clypeus: areolate part with 4 pairs of setae symmetrically arranged on each side, and about 30 scattered peculiar button­like sensilla; plagulae subtriangular, without setae; clypeal ratio about 3.2. Labrum: anterior ala triangular, medial margin reduced to a vertex; posterior margin of each posterior ala with about 20 well developed notches. Buccae without spiculum and without setae. Mandible: about 5 lamellae, first lamella with about 6 teeth, intermediate lamella with about 11 teeth; ventral side with small scales, producing a ‘hairy’ appearance. First maxillae: distal lobe of the medial projections clavate, distal part of the telopodite attenuate. Second maxillae: telopodite with a small apical claw. Forcipular segment: coxosternum 1.1 times as wide as long; cerrus composed of two lateral groups of setae. Forcipules: article I 1.7 times as long as wide, with a small distal tooth; article II without teeth; article III with a tooth; tarsungulum with a shallow, obtuse, basal tooth; poison calyx reaching article II. A total of 45 leg­bearing segments. Last leg­bearing segment: sternum 1.2 times as wide as long; about 20 pores on each coxopleuron; telopodites slightly swollen, with a small apical tubercle bearing two tiny spines.
