Neastacilla tattersalli Lew Ton and Poore

Neastacilla falclandica . — Tattersall, 1921: 244, pl. 10, fig. 1 (not Ohlin, 1901: 266, pl. 20).

Neastacilla tattersalli Lew Ton and Poore, 1986a: 193–195 , fig. 3.— Lew Ton and Poore, 1986b: 99.— ICZN, 1987: 214.

Diagnosis of female. Eyes large and oval. Head without dorsal elevations, anterolateral lobes angular; lateral margin of head and pereonite 1 not incised. Pereonites 1–7 without dorsal elevations. Pereonites 2–4 with only small lateral expansions. Pereonite 4 9 times as long as pereonite 3. Pleon slightly longer than pereonites 5–7 combined, no distinct lateral wings present, apex bluntly rounded. Size unrecorded.

Male. Unknown.

Distribution. New Zealand, North Island.

Remarks. This species is diagnosed from the description of Lew Ton and Poore (1986) and most closely resembles Neastacilla falclandica . N. tattersalli can be distinguished from the former species by the long tapered pleon without lateral wings, angular anterolateral lobes of the head and the presence of two setae on the uropodal exopod.
