Kalliapseudes struthi Bamber, 2005

( Fig 55 )

Kalliapseudes struthi Bamber, 2005: 642–645 , Figs. 12–13 . Drumm and Heard, 2006a: 35, 37. Drumm and Heard, 2006b: 18, Type material. Holotype female (WAM C 33951); paratypes: 1 female and 1 subadult (WAM C 33952), 1 female (NHM.2004.196), 7 juveniles (WAM C 33953), 1 male and 1 juvenile (NHM.2004.197–198), 1 female (WAM C 33954).

Material examined. 1 female paratype ( WAM C 33954), Esperance Bay , SW Australia, 33°53.6'S, 121°56.36'E, 38.4 m depth, coll. and det. R.N. Bamber, Sept. 2003 ; 1 subadult male and 1 juvenile, paratypes ( NHM.2004.197–198), Esperance Bay , SW Australia, 33°53.948'S, 121°56.536'E, 39.68 m depth, sand with rhodoliths, coll. and det. R.N. Bamber, Feb. 2003 .

cles. Antenna first peduncle article with short simple seta on outer subdistal corner; third peduncle article with one plumose seta on inner margin; flagellum with six articles. Labrum complex without cusps. Terminal spiniform seta of mandibular palp approximately 3.25 times as long as broad. Female cheliped fixed finger cutting edge with spinules interspersed with serrate tubercle. Cheliped and pereopod 1 exopodite with two plumose setae. Pereopods 2 and 3 dactylus with digitiform lobe. Pereopod 5 propodus without short bipinnate setae on inner surface. Pereopod 6 dactylus with subterminal seta. Uropod basal article approximately three times as long as broad; exopodite with two articles.

Type locality. Esperance Bay , SW Australia, 33°53.705'S, 121°56.771'E, 38.6 m depth (Fig. 1, number 24) .

Geographic distribution. Known from Esperance Bay, SW Australia, 38–40 m depth only.

Remarks. One of the characters Bamber (2005) mentions that distinguishes this species is the presence of only three or five sensory setae on the dactylus of pereopods 4 and 5, respectively (i.e. without a ‘brush’ of setae). However, several other Kalliapseudes species only have three–five sensory setae, such as K. primitivus and K. langi . The other distinguishing character that Bamber mentions is the bipinnate setae on the propodus of pereopod 6 being restricted to the distal half. We believe Bamber may have described and illustrated the pereopod 6 of the subadult male because the subadult male paratype we examined had a pereopod 6 ( Fig. 55A ) exactly like it and the paratype female we examined had a pereopod 6 ( Fig. 55B ) that was more setose and the bipinnate setae of the propodus covered more of the ventral margin.

Kalliapseudes struthi appears most similar to Kalliapseudes dongarae n. sp.. However, as mentioned under Kalliapseudes dongarae n. sp. K. struthi differs by having a smaller body size, a less pronounced rostrum, fewer setae on the pleotelson and antennal squama, cheliped and pereopod 1 with exopodite having two plumose setae, and fewer sensory setae on the dactylus of pereopods 4 and 5.

The antennule ( Fig. 55C ) of the subadult male is similar to the female, but has more aesthetascs and the dactylus of pereopod 6 ( Fig. 55A ) is the same length as in the female ( Fig. 55B ).
