Pseudoprellicana n.gen.

Diagnosis. Antenna 2 flagellum 2-articulate. Gills present on pereonites 3 and 4. Pereopods 3 and 4 absent. Pereopod 5 3-articulate. Pereopods 6 and 7 six-articulate. Mandibular palp 3-articulate. Molar absent. Abdomen with two pairs of appendages.

Etymology. The name is derived from “ Pseudo ” and “ Prellicana ” because the new genus strongly resembles Prellicana . Gender: feminine.

Type species. Pseudoprellicana johnsoni n.sp., by present designation and monotypy.

Remarks. The new genus is close to Prellicana Mayer, 1903 . The main difference between these two genera is the presence of one pair of uniarticulate abdominal appendages in Prellicana and two pairs in Pseudoprellicana . In connection with the mouthparts, the inner plates of the maxilliped are partially fused in Prellicana , with three denticulate nodular setae, while in Pseudoprellicana the inner plates are not fused and instead of nodular setae the surface is transformed into a structure similar to a molar process. Pereopods 6 and 7 are similar in both genera but pereopod 5 is slightly different. Although in both genera the pereopod 5 is 3-articulate, in Prellicana the basal article is almost divided into two articles while it is not in Pseudoprellicana . The new genus is readily distinguished from Jigurru by the presence of two instead of three pairs of gills.
