Hemilamprops diversus Hale, 1946

Hemilamprops diversus Hale, 1946: 183–187 , figs 3–4.

Type material. Holotype: SAMA 2809 , ovigerous female . Allotype: SAMA 2810 , adult male. Off Eden , New South Wales, Australia .

Diagnosis. Carapace without lateral ridges, without setae, dorsal crest entire, ocular lobes extending to anterior margin of carapace. Telson 1.2 length of uropod peduncles, with 3 pairs lateral setae, 5 terminal setae, outermost pair long, median 3 setae equal in length. Uropod exopod article 1 0.6 length of article 2. Adult male antenna extending to posterior border of pleonite 6; telson with 4 pairs lateral setae, median seta of telson longer than inner pair, although outer pair longest.

Depth. 50–150 m.

Distribution. Southeastern Australia, 37°4’S, 149°54’E.

Remarks. Hemilamprops diversus can be distinguished from the other Australian species by the eyelobe extending only to the anterior border of the carapace. In the other Hemilamprops from Australian waters, the pseudorostrum extends anterior of the eyelobe. The most similar species of Hemilamprops to H. diversus is H. merlini from the Angola Basin, which can be distinguished by the terminal setae of the telson. In H. diversus the telson terminal setae are unequal in length, while in H. merlini the telson terminal setae are equal in length.
