Paralamprops arafurensis Jones, 1969: 122–123 , fig. 11a–h. Type material. Holotype : UZMK , ovigerous female. Arafura Sea, 7°34’S , 132°44’E . Diagnosis. Carapace with 2 lateral ridges, marginal carina entire, ridge on pseudorostrum; eyelobe with lenses or tumidities. Antennule article 1 not expanded; accessory flagellum subequal to main flagellum. Telson shorter than uropod peduncles, with 5 terminal setae, terminal setae equal. Uropod endopod article 1 twice length of articles 2 and 3 together. Adult male unknown. Depth . 390 m . Distribution . Arafura Sea, 7°34’S , 132°44’E . Remarks . Platytyphlops arafurensis is most similar to P. lowryi , but can be differentiated by the uropod endopod setation; in P. arafurensis article 1 of the uropod endopod has 20 setae whereas in P. lowryi there are at least 28 setae on the article 1 of the endopod. The ridge patterns of the carapace are similar, although P. lowryi has a dorsal crest down the pereonites, while this crest is not present in P. arafurensis .
