Hemikalliapseudes hanstroemi Lang, 1956

Hemikalliapseudes hanstroemi Lang, 1956: 217–221 , Figs. D, E. Guţu, 1998: 180. Sieg, 1982: 3. Bamber, 2003: 227, 235. Type material. None apparently by original designation.

Material examined. None available for study. Tentative diagnosis prepared from that by Lang (1956a).

Diagnosis. Anterolateral corners of pereonites 2–6 with apophysis. Antennule inner flagellum multiarticulate. Antenna flagellum with more than five articles. Mandibular palp first article with more than five setae. Pereopod 1 with exopodite. Male cheliped fixed finger cutting edge with proximal tooth approximately twice as long as broad.

Type locality. Congo River , 06°18'S 17°07'E, depth 40 m.

Geographic distribution. Known from the type locality only (Fig. 1, number 5).

Remarks. The material Lang (1956a) examined (one adult male) is apparently lost. It is supposed to be housed at the Universitets Zoologisk Museum in Copenhagen, but staff informed me they do not have it. Fortunately, the original description is detailed and adequately illustrated.

This species can easily be distinguished from its congeners by several characters including 1) anterolateral apophyses on pereonites 2–6, 2) a multiarticulate antennule inner flagellum, 3) an exopodite on pereopod 1, and 4) the dactylus of pereopods 4 and 5 being shorter than the propodus.
