Family Parapseudidae Guţu, 1981

Remarks. The family Parapseudidae was erected by Guţu (1981) and its diagnosis later revised by Larsen (2005) and Guţu (2008). Key features of parapseudids include the (1) absence of a well-developed spiniform coxa on pereopod-1; (2) large size of pereopod-1, in relation to pereopods 2 and 3; and (3) small length of pereopod-4 dactylus (smaller than some distal spines on the propodus). The family contains two subfamilies Pakistanapseudinae Guţu, 2008 and Parapseudinae Guţu, 2008 , which were erected by Guţu (2008) as tribes and then promoted to subfamily rank by Błażewicz-Paszkowycz & Bamber (2012). Guţu (2008) also provided identification keys to these tribes and genera. The two subfamilies are differentiated by the relative length of the pleonites and the presence or absence of a dorsotransversal row of small setae on the first pleonite ( Guţu 2008). Preserved specimens of this family are notoriously fragile and thus often incomplete ( Guţu 1996, 1998c), resulting in taxonomic difficulties.
