Type locality. Wasim , Kenya, East Africa, 18 m depth (Fig. 1, number 18) .

Geographic distribution. Known from type locality only.

Remarks. Kalliapseudes makrothrix is the type species of the genus but unfortunately Stebbing apparently did not designate any type material and if he did deposit material in a museum it is either lost or nobody knows where it is located. Based on the crude original description and illustrations (hence, no diagnosis is presented), it cannot be known for certain that this species belongs to the genus Kalliapseudes . Stebbing (1910) stated that the exopod of the first pereopod was “apparently a single jointed rudiment,” but we are assuming the distal end was destroyed. Stebbing (1910) did not illustrate the second pereopod as having a setose digitiform lobe on the dactylus but it cannot be ruled out that he simply overlooked this character since it is very small and hard to see. Topotypic material will have to be examined in order to establish a neotype for this species. Since it is unclear to which genus it belongs, it is classified as Kalliapseudinae incertae sedis.

Bamber et al. (2003) recorded K. makrothrix from the Andaman Sea off Thailand but this justification seems unwarranted because the original description and illustrations are scant and crude and they did not examine any topotypic material. Due to the large geographic distance between the type locality and Thailand, this is likely to represent a new species and a detailed examination of topotypic material will probably reveal morphological differences. Bamber et al. (2003) also considered K. makrothrixoides Băcescu, 1980 and K. borcei Băcescu, 1980 , which are found in the NW Indian Ocean, junior synonyms of K. makrothrix . Guţu (2006) considered them valid species based on variations in setation and spination patterns. Unfortunately material of these two species were unavailable for study so their status currently remains unresolved.
