Diagnosis. A Tygarrup species with 45 leg­bearing segments. Body length of adults reaching at least about 3 cm. Head about 1.5 times as long as wide. Each side of the clypeus with about 10 setae. Forcipular articles I and III each with a tooth, article II and tarsungulum without teeth. Sternal pores lacking in both sexes.

Type material. Holotype: male, 27 mm long, adult ( Miyosi, 1957).

Type locality. ‘Takara­Zima’ [= Takarajima], Ryukyu Ids ( Miyosi, 1957).

Depository of type material. Unknown.

Material examined. 2 specimens: males, subadult (22 and 23 mm), from Nakanoshima Id. (Tokara Ids), Toshima­mura, Kagoshima­gun, Kagoshima Pref., Ryukyu Ids , 2. V .1987, S. Nomura leg., coll. AM .

Description. Body length of adults reaching at least 2,7 cm. Body colour yellow, with dark patches along the trunk; head and forcipular segment darker. Head 1.5 times as long as wide; frontal line rounded. Antennae about 3.8 times longer than the head width. Apical sensilla about 20 µm long. Clypeus with an entire plagula covering most of the clypeus, areolation only present along the anterior margin of the head; up to about 10 setae on each side, in the antero­medial part of the plagula. Labrum: anterior ala triangular, medial margin reduced to a vertex; posterior margin of each side­piece sinuous. Buccae without setae. Mandible: about 6–8 well­developed lamellae; first lamella with 5 teeth. First maxillae: anterior corners of coxosternum not projecting; each medial projection about 1.6 times as long as wide, internal margin with many setae, distal lobe curved inward; each telopodite about 3.5 times as long as wide, curved inward. Second maxillae: article I of telopodite about 3.8 times as long as wide; article III about 2.2 times as long as wide, densely covered with setae; apical claw in form of a tubercle with 2–3 spines. Forcipules: article I about 1.6 times as long as wide, with a distal tooth; article II and tarsungulum almost untoothed, article III with a small tooth. A total of 45 legbearing segments. Sternal sulcus apparently not furcate; sternal pores lacking in both sexes. Last leg­bearing segment: sternum subtriangular, about 1.3 times as wide as long.
