Remarks. The new genus Jigurru shares some characters with Caprellina (Nicolet, 1849) and Prellicana Mayer, 1903 . Jigurru appears to be closer to Caprellina than Prellicana on the basis of the presence of three pairs of gills, reduced pereonite 5 and two pairs of appendages in the abdomen. Nevertheless, the small size, general features of the body, the incomplete articulation of the basal article in the pereopods 5, the shape of pereopods 6 and 7, and the partially fused inner plates of the maxilliped strongly resemble Prellicana . Prellicana , however, has only two pairs of gills and one pair of abdominal appendages whereas Jigurru possesses three pairs of gills and two pairs of abdominal appendages.
