Some Amphipoda, Isopoda and Tanaidacea from Cook Strait

Family Photidae

Family Photidae

Eurystheus thomsoni? (Stebbing), 1888.

Cammaropsis thomsoni Stebbing, 1888: 1103–1107, pl. GXV.

Eurystheus thomsoni, Stebbing, 1906: 613–614.

Material Examined: Station GUL (VUZ. 54), 29 females and juveniles, up to 4½ mm, mostly very small, some ovigerous; 1 male.

Distribution: Cook Strait; Challenger Stn. 168, "off New Zealand, July 8, 1874; lat. 40°28′S.; long. 177°43′E.; depth 1,100 fathoms; bottom blue mud; bottom temperature 37–2°".

Discussion: This species is identified with considerable doubt. The females are reasonably like that described by Stebbing, but the male has 3 spines, 1 dorsal and 2 lateral. These specimens are obviously distinct from the other Eurystheus taken at the same station, and the differences are emphasised by the complete leaching out of the pigment of the eyes in this species.

Eurystheus sp.

Material Examined: Station GUL (VUZ. 54), 36 females and juveniles, 1–4 mm, some ovigerous.

Discussion: It is difficult to identify these with any of the several poorly described species from New Zealand since most of the descriptions depend on the male for good characteristic features, and males are lacking from this collection.
