|Abstract||On his journey to Australia, Prof. Dr. L. G. M. Baas Becking collected several specimens of Parartemia zietziana, which he kindly handed over to me for further examination. As it is a very little known species, the few details given below may add to our somewhat scanty knowledge.|
Sayce described this species in 1903, creating a new genus to receive it, and his material consisted of about 20 ♂ ♂ and only 1 ♀ (Sayce, 1903, p. 231 sqq.) The locality is given as "brackish-water swamp near Lake Alexandrina, South Australia".
The only further reference I have been able to find was when Calman (1913) identified a few Phyllopoda "not unlike Artemia" as this species.
They were collected from salt-works near Geelong, Victoria, and were said to die at a concentration of 7°—8° B. (s.g. ± 1.055).
The material of Baas Becking consists of the following: "Port Price 1" (26 III '36), 69 ♂♂, 39 ♀♀, 77 juv. "Port Price 2" (26 III '36), 35 ♂♂, 35 ♀♀, great many juv.
Lake Voigt (26 III '36), 37 ♂♂, 4 ♀♀, 2 juv. "Port Price" is a salt-work, which derives its water from the sea. It is situated on the East coast of Yorke Peninsula, near the top of Bay St.
P.P. 1: Gipsum pond, concentration about 23 % total salt. Temp. 27° C.
P.P. 2: Pickle pond, concentration 16 % total salt.
Lake Voigt lies near the South end of the East coast of Yorke, about 6 km inland. The specimens were taken from a ditch (where there was great abundance of Dunaliella viridis and D. salina). Concentration about 5 % total salt, temp. 16° C.
