Terayama (1996) - This species belongs to the graeffei-group of Brown (1978) and especially resembles Anochetus graeffei. But it is separable from the latter by the following characteristics: mandibular shaft only weakly broadened anteriorly (maximum width of shaft 2.0 x its basal width in graeffei); petiolar node thin and carinate dorsally (not carinate in graeffei); first gastral tergite with relatively large punctures densely (with very small punctures sparsely in graeffei).

Holotype. HL 0.88 mm; HW 0.85 mm; SL 0.73 mm; CI 97; SI 86; ML 0.53 mm; MI 60; WL 1.23 mm; AW 0.51 mm; PL 0.24 mm; PH 0.45 mm; DPW 0.30 mm; TL 4.0mm.
Head: frons microreticulate with striae; genae smooth and shining. Mandibles 0.83 x head length with straight dorsal inner margin; shaft only weakly broadened anteriorly; dorsal margin without tooth; apical portion with 3 acute teeth of which ventral and dorsal ones are subequal in length; intercalary tooth smallest Antennae with 12 segments; scape long, but not reaching posterolateral comer of head; pedicel 2.0 x as long as wide; 3rd to 10th segments each almost as long as wide; 11th segment slightly longer than wide; terminal segment 2.9x as long as wide. Eyes convex, 0.13 mm in maximum length and larger than the maximum width of mandibular shaft, with short erect hairs.
Pronotum microreticulate and coarsely punctate; dorsal length excluding cervix 1.1 x dorsal width; anterior margin carinate. Sculpture on dorsal face of mesonotum as on pronotum; mesopleura smooth and impunctate in most part Posterolateral comer of propodeum broadly rounded in lateral view; dorsal face of propodeum microreticulate and coarsely punctate; lateral faces with numerous longitudinal striae.
Petiole thin, carinate dorsally, with straight anterior margin and very weakly convex posterior margin in lateral view; in frontal view, lateral margins subparallel and dorsal margin broadly rounded. Subpetiolar process low, with an anteroventral lobe.
First gastral tergite slightly wider than long in dorsal view; anterior 3/5 microreticulate with relatively large punctures densely; the rest smooth with scartered shallow punctures. Second gastral tergite 1.3 x as wide as long in dorsal view; smooth with scattered shallow punctures. Legs subopaque.
Head including mandibles and antennae brown; alitrunk and petiole dark brown; gaster blackish brown; legs yellowish brown. Short suberect hairs present on dorsa of head and alitrunk; the longest pronotal hair about 0.09 mm in length.
Paratype. HL 0.98 mm; HW 0.97 mm; SL 0.75 mm; CI 99; SI 77; ML 0.55 mm; MI 56; WL 1.32 mm; AL 0.65 mm; PL 0.28 mm; PH 0.50 mm; DPW 0.35 mm; TL 4.7mm.
General shape of head similar to that of the worker with the usual caste differences. Eyes 0.20 mm in maximum length. Ocelli small, forming a right triangle; anterior ocellus ca. 0.04 mm in diameter.
Alitrunk and petiole: in profile dorsal outline of alitrunk convex, forming an arch from anterior end of pronotum to posterior end of propodeum; pronotum microreticulate with punctures, 0.60x as long as as wide excluding anterior cervix in dorsal view, with its anterior margin carinate; mesonotum microreticulate with punctures, but punctures smaller than those on pronotum; mesopleura smooth and shining, impunctate in most part. Petiolar node thin, carinate dorsally.
Coloration as in worker.
Holotype. Worker, Mt. Omoto-dake, Ishigaki-jima, Okinawa Pref., 10.XI.l993, K. Yamauchi leg.
Paratypes. 1 female, 9 workers, same data as holotype.
The specific name is the Japanese noun shohki, which is the name of a strong god of Japan.
