Remarks on type material. Numerous syntype specimens, mostly mancae and females and only two males in CRU 9234. Several females and mancae were intact but most were mutilated or fragmented specimens. The male illustrated here is lacking part of the left antenna and the right uropod. The other male lacked pleopods; these were possibly removed by Hansen for illustration. An intact female from the same sample (CRU 9234) was selected for the illustration. Diagnosis Pereonite 1 in female with no median dorsal tubercles or spines; pereonite 5 in female length 2.2 width. Male with rook spines on peronites 1–4. Pereonite 5 in female length 2.2 width, in male length 4.4 width. Pleotelson posterolateral margin anterior to uropods without spines or tubercles. Antennula with 3 articles altogether. Pereopods II– VII ... |
