Kalliapseudes primitions . Băcescu, 1980: 375.

Material examined. Type Material: Holotype, male ( ZMA IS.100.600), Indonesia, between the islands Ceram– Laut and Geser, Siboga Exp. St. 172, coll. M. Weber, 1899, det. H.F. Nierstrasz.

Diagnosis (adult male). Pleotelson tapering posteriorly to slightly indented tip with posterior margin with row of simple setae and without two long terminal plumose setae. Antennule first peduncle article lacking ventral spiniform setae; last two peduncle articles very short; accessory flagellum of six articles; proximal articles of main flagellum with dense clusters of aesthetascs. Labrum without cusps. Cheliped fixed finger cutting edge with proximal tooth. Cheliped and pereopod 1 exopodite with three plumose setae. Pereopods 2 and 3 propodus with very stout pectinate spiniform seta subdistally on the inner surface; dactylus with digitiform lobe bearing less than five sensory setae. Pereopods 4 and 5 dactylus with less than five sensory setae. Pereopod 5 propodus with short terminal bipinnate setae. Pereopod 6 dactylus with single subterminal seta and longer than ischium, merus, carpus and propodus combined. Uropod basal article approximately 2.7 times as long as broad, without setae on lateral margins.

Female. Unknown.

Type locality. Geser , Ceram Island, Indonesia, littoral (Fig. 1, number 22) .

Geographic distribution. Known from type locality only.

Remarks. Unfortunately the holotype is missing the antennae, chelipeds, first pereopods, second pereopods, rostrum and most of the mouthparts. It can be distinguished from the only other known Indo–West Pacific Kalliapseudes species , Kalliapseudes bamberi n. sp. (Sabah, Malaysia) by lacking plumose setae on the posterior margin of the pleotelson and the male pereopod 6 dactylus being much longer. The recognizable remnants of the male holotype are illustrated in figures 53 and 54.

Kalliapseudes senegalensis Guţu, 2006: 127 , 128–134, Figs. 168–185. Drumm, 2007: 18.

Type material. Holotype female no. 250.296; allotype male no. 250.297; 4 female paratypes no. 250.298. MHN Grigore Antipa.

Material examined. None available for study. Diagnosis prepared from original description ( Guţu, 2006).

Diagnosis (juvenile). Rostrum rounded. Pleotelson tapering posteriorly to indented tip, posterior margin with row of simple setae and lacking two long terminal plumose setae. Antennule first peduncle article lacking ventral spiniform setae; accessory flagellum of two articles. Antenna flagellum with six articles. Cheliped and pereopod 1

exopodite with four plumose setae. Pereopods 2 and 3 dactylus with digitiform lobe. Pereopod 6 dactylus with three subterminal setae. Uropod basal article approximately 2.7 times as long as broad; exopodite with three articles.

mm.

Type locality. Dakar, Senegal, West Africa , North Atlantic Ocean, 1 m depth (Fig. 1, number 23) .

Geographic distribution. Known from type locality only.

Remarks. Kalliapseudes senegalensis is the second species of Kalliapseudes to be found off Dakar ( K. magnus being the other species). See the “remarks” section under K. magnus for the differentiation of these two species. The diagnosis must be considered tentative since it is based on a juvenile.
