Description
Austrosignum sp.
(Fig. 4)
Material examined. Ovigerous ♀, 2.2 mm, Antarctica, Palmer Peninsula, Wiencke Island, 64°48.0’S, 63°22.4’ W, 25 m; label data: “ Austrimunna incisa Richardson; Type!; 11° 822—Drague, 25m; (2–5–05); Museum Paris; Ile Wiencke; Mission Charcot; 1906”, MNHN-IU-2019-3352.
Remarks. This female specimen was in the same vial as the lectotype of Cryosignum incisum (Richardson, 1908), but it is clearly not that species. It has the defining characters of Austrosignum, including an unelaborated head frontal margin, prominent to elongate eyestalks and a distally angular, pointed uropodal endopod. Without a male, we are unable to describe this species, although it is unlike females of the other four species in the genus, in having eyestalks that are longer and thinner than the other known species. Compared to the other species with a distally pointed pleotelson, A. latum sp. nov., this species has a narrower body.
