Type material. Holotype male; allotype adult female; 7 paratypes (6 males and 1 female). Amakusa Biological Station , Japan.

Material examined. None available for study. Diagnosis prepared from original description ( Shiino, 1966).

Diagnosis (adult female and male). Rostrum rounded. Pereonites without anterolateral apophyses. Pleotelson tapering posteriorly to rounded tip and with two terminal plumose setae. Antennule accessory flagellum with five (male) or six (female) articles. Antenna first peduncle article with one simple seta on outer subdistal corner; third peduncle article with two plumose setae on inner margin. Terminal spiniform seta of mandibular palp approximately three times as long as broad. Cutting edge of male cheliped fixed finger with large proximal triangular tooth; palm with long narrow tooth on anterior margin. Cheliped and pereopod 1 exopodite with two plumose setae. Pereopods 2 and 3 dactylus lacking digitiform lobe. Pereopod 5 propodus with short bipinnate setae on inner and outer surfaces. Pereopod 6 dactylus lacking subterminal seta(e); male pereopod 6 dactylus as long as merus, carpus and propodus combined. Uropod basal article approximately 2.5 times as long as broad and with short spiniform seta on inner distal corner.

Type locality. Sea of Tomioka , Amakusa, Japan, 16 m depth (Fig. 1, number 25) .

Geographic distribution. Known from type locality only.

Remarks. Unfortunately attempts to contact the Amakusa Biological Station to borrow type material were unfruitful. Bamber et al. (2003) recorded this species off Thailand and “corrected” Shiino’s description by indicating a digitiform lobe on the pereopod 3 dactylus and a subterminal seta on the pereopod 6 dactylus; however, until type or topotypic material can be examined to determine the taxonomic status, the placement of this species within the genus Kalliapseudes is tentative. actually is much longer in K. primitivus (longer than the ischium, merus, carpus and propodus combined). Also, in the original description by Nierstrasz (1913), some of the figures are mislabeled (eg. pereopod 6 is labeled as “thoracopod IV”).

If K. tomiokaensis lacks digitiform lobes on the dactylus of pereopod 2 and 3 then it is very similar to Phoxokalliapseudes (= Kalliapseudes ) gobinae but can be distinguished from it by having a much shorter dactylus on the sixth male pereopod and a large proximal tooth on the cutting edge of the fixed finger. Besides lacking digitiform lobes on the dactylus of the second and third pereopods (which were shown to be homoplasious characters in the cladistic analysis) these two species also share these characters: 1) two terminal plumose setae on the pleotelson, 2) two plumose setae on the exopodite of the cheliped and first pereopod, 3) no subterminal setae on the pereopod 6 dactylus and 4) a short spiniform seta on the inner distal corner of the uropodal basal article. Shiino (1966) did not mention or illustrate the labrum with cusps or the presence of spiniform setae on the ventral surface of the first antennular peduncle article but examination of the type material is needed to determine if these two characters are present, as these two characters tend to co–occur with the terminal plumose setae on the pleotelson.
