B63F8783FF9BFFC20564B01DFE008599.taxon	discussion	Remarks. The species of this genus all possess heads with reduced lateral and antennal spines, eyes with few ocelli, narrow triangular rostrums, and appendices masculinae with long needle-like stylets. Although a stylet similar to Stenetrium adrianae occurs in this genus, the long setae on the stylet tip and the differences in the body shape, cephalon shape and the shape of the remaining pleopods clearly distinguish this genus as a separate unit.	en	Serov, Peter A., Wilson, George D.

B63F8783FFA4FFC1051FBC26FE6084E1.taxon	discussion	. Remarks. The genus Hansenium is most closely related to Stenetrium sensu stricto in overall morphology but can be distinguished most prominently by the large, pointed extended carpus that participates in grasping with an elongated dactylus. Hansenium also has large reniform eyes, reduced lateral spines and a broad short rostrum. A correction is made to the nomenclature of the species described as S. caicosensis Kensley & Heard, 1991 by changing it to H. caicosense, in order that the species name is consistent with the gender of the genus, i. e. neuter.	en	Serov, Peter A., Wilson, George D.

B63F8783FFA7FFC6010EB0AEFD088A46.taxon	description	Figs 1 G, H, 3 D Type species. Liocoryphe minocula (Menzies & Glynn, 1968). Species included. See Table 1. Etymology. Liocoryphe is derived from the Greek words " lius " meaning smooth, and " coryphe " meaning crown of the head. The name refers to the smooth head of this genus which lacks spines or lateral fields. The gender is feminine. Diagnosis. Head dorsal surface smoothly rounded and frontal margin with no lateral spines, antennal spines rounded and much reduced, shorter than rostrum. Rostrum short, broad, rounded; eyes reduced to small rounded, anterolateral group of ocelli. Antennular flagellum with 4 - 6 articles. Antennal article 1 without lateral spines. Maxilliped endopodite distal margin with 4 fan setae. Pereonite lateral margins blunt to rounded; double coxal extensions visible on pereonites 2 - 4, single extensions on pereonites 5 - 6. Male pereopod I dactylus shorter than propodal palm; propodal palm serrate; carpus ventral margin with large, broad, blunt extension; male pereopod covered in long, dense setae from ischium to propodus. Male pleopod 11 protopod with small pointed apical extension; exopod subapical; appendix masculina elongate with blunt distal tip and subapical row of short, proximally directed cuticular hairs, distal tip narrowed slightly. Pleotelson with 2 free pleonites. Pleotelson longer than wide, smoothly truncated to posterolateral spine then smoothly rounded with no telsonic projection between uropods. Remarks. Liocoryphe is closely related to Hansenium and is distinguished by the males having an extended carpus. This genus gains separate generic status by lacking lateral spines on the head, having a small round group of ocelli, a short blunt rostrum, and a large blunt extension on the carpus that does not participate in grasping with the dactylus.	en	Serov, Peter A., Wilson, George D.

B63F8783FFA0FFC606CDB80AF7108508.taxon	discussion	Remarks. The use of plesiomorphic and / or variable characters while ignoring other diagnostic features has clouded the definition of this genus. Protallocoxa Schultz, 1978 originally was based on a freely-articulating, protruding coxa of the first pereopod. Schultz (1978) considered this character to be a primitive asellote feature and used it as a justification for a new superfamily, the Protallocoxoidea. Wilson (1980) later showed that this feature was a plesiomorphic condition in brooding females of many asellote species, including Stenetrium, and synonymised Schultz's taxon back into the Stenetriidae as S. weddellense. In our proposed classification, Protallocoxa regains its generic status within the family because the member species, P. weddellense and P. abyssale have several unique features among the Stenetriidae, particularly a lack of coxal projections visible in dorsal view and reduced marginal spines on the body.	en	Serov, Peter A., Wilson, George D.

B63F8783FFA3FFC406E4B97CFD838D0B.taxon	discussion	Remarks. The unifying features of Tenupedunculus include the shape of the male pleopod I, the appendix masculina of pleopod 11, the number of dorsally visible coxal lobes, and a head with large, robust lateral spines and reduced antennal spines. The degree of enlargement of the lateral spine and reduction of the antennal spine varies throughout the genus from the extreme cases as seen in Stenetrium acutum and Stenetrium inflectifrons to the more subdued forms of Stenetrium pulchrum and Stenetrium drakensis (nee Protallocoxa) S. drakensis was placed in this genus, even though no males were collected, because of its close resemblance with Stenetrium beddardi in the cephalon armature, the pleotelson shape and the presence of 2 coxal lobes on pereonite I. Schultz (1982) also noted a close resemblance between these two species. The concept of Tenupedunculus Schultz, 1982 was based on lack of eyes in T. elongatus, a dubious diagnostic feature (cf. Wolff, 1962; Hessler & Wilson, 1983). All other features used in Schultz's (1982) description do not unequivocally define the new genus among all stenetriids. Schultz (1982) even states that the " male pleopod 2 and others [are] Stenetrium like ". The similarities to Stenetrium pulchrum and Stenetrium haswelli in the male pleopods, the pleotelson and the dorsally visible coxal lobes of T. elongatus, however, place this species within this genus. Although T. elongatus does not represent the typical form of this genus as seen in S. acutum and S. inflectifrons, the genus name is valid and has priority. Therefore Tenupedunculus is used as the name for this genus. Tenupedunculus may be further separated into two groups after closer examination of the types.	en	Serov, Peter A., Wilson, George D. F.
