Raggi dorsali molli (totale) : 6 - 7; Raggi anali molli: 4 - 5. Escal bulb with a membranous anterior crest. Distal escal appendage an elongate, cylindrical stalk, flattened and expanded distally, bearing slender filaments on periphery, without elongate prolongation emerging from bases of escal hooks. Posterior escal appendage broad, laterally compressed (Ref 27827).
