Genus
(1) Aegisthus Giesbrecht, 1891details
Rem.:
type: Aegisthus mucronatus Giesbrecht,1891. 2 spp. + 1 doutbtful (inc. sed.)
For Huys (1988, p.124) the sexual dimorphism amongst the three known Aegisthus species is markedly constant. Apart from differences in the antennular sgmentation in the male, Boxshall (1979) found that the Mx2 and Mxp are closer to the female condition in A. aculeatus males than in A. mucronatus males.

Species
[2] Aegisthus mucronatus Giesbrecht, 1891 (F,M) [Figs]
Species
[3] Aegisthus spinulosus Farran, 1905 (F) [Figs]
According to Conroy-Dalton & Huys (1999) this species is incertae sedis. There are several similarities between this species and Andromax muricatus.
Identification characters:
Female: Rostrum ending in short pointed. Anterior prosme without chitinuous net. Posterior margin of dorsal metasomal segments with a pair of spines.
Genus

1 sp.
Species
[1] Jamstecia terazakii Lee & Huys, 2000 (F) [Figs]
Genus
(4) Nudivorax Lee & Huys, 2000details
Rem.:
1 sp.
Species
[1] Nudivorax todai Lee & Huys, 2000 (F,M) [Figs]
Genus
(5) Scabrantenna Lee & Huys, 2000details
Rem.:
Total: 1 sp.
For Lee & Huys (2000, p.41) this genus can be considered a transitionary genus between the more primitive genera, Nudivorx and Andromastax, and the truly planktonic Aesisthidae, Aegisthus. It shares with Aegisthus the strongly reduced mouthparts and the distally elongate antennules in the male. S. yooi is particularly reminiscent of A. aculeatus
