Diagnosis (modified after Larsen 2005)

Female

Body almost nearly cylindrical and filiform. Carapace longer than wide. Eye-lobes and visual elements absent. Pleon long, at least 0.4 times the length of pereon, without lateral edges of dorsal shield. Pleonites and pleotelson not fused. Pleotelson with dorsal plate not covering uropods.Antennule with four articles. Antenna with 5–6 articles. Mandibles with pointed molar. Maxillipedal endites without distal setae; palp article 2 without multifurcate seta. Chelipeds attached via lateral sclerite. Pereopods slender, with coxae, dactylus and unguis not fused to a hook. Pleopods absent in female. Uropods long (about 0.5 times as long as pleotelson), biramous; endopod with two articles; exopod with 1–2 articles.

Remarks

Larsen (2005) proposed a diagnosis of the genus and considered the “pleonites long, almost as long as the pereonites and pleotelson”. According to Larsen (2005), Filitanais vulgaris, even with a long pleon, was classified within the genus Collettea because of its broad mandibular molar. Larsen (2005) also wrote that F. curticaudus might not belong to Filitanais because of its short pleon, about 0.4 times the length of the pereon.

On the other hand, Błażewicz-Paszkowycz (2005: key) characterized Filitanais as having a pleon longer than half the length of the pereon, and the pleotelson clearly longer than wide. Our examination of the six species of the genus, however, revealed that the pleon of F. moskalevi is only 0.4 times the length of the pereon, which casts doubt on the inclusion of this species within the genus. Alternatively, we propose to change the diagnosis of Filitanais as having a pleon at least 0.4 times the length of the pereon.
