New species of Skrjabinoclava (Nematoda: Acuarioidea) from the Semipalmated Sandpiper (Calidris

These were Calidris
canutus piersmai, Calidris

Hartlaub (1847) identified this species as Calidris
arenaria Illiger, 1811, following Lichtenstein (1823) who had stated that "specimens from Montevideo suggested that this may be the bird that Azara referred to".
In 2014 72 waterbird species were recorded in the conservation area, including the globally endangered great knot (Calidris
tenuirostris), far eastern curlew (Numenius madagascariensis) and spotted greenshank (Tringa guttifer).
The estuary plays a key role as feeding and roosting site for several Nearctic birds (Calidris
fuscicollis, Limosa haemastica, Calidris
canutus, among others) as well as Patagonian species, such as Charadrius falklandicus, Haematopus leucopodus, and Pluvianellus socialis (Ferrari et al., 2002).
Mole Crabs are the dominant members of the sandy-beach food web in the swash zone at Drakes Beach, and we have often observed Sanderling (Calidris
alba), Willet (Tringa semipalmata), and Marbled Godwit (Limosa fedoa) foraging on Mole Crabs along this stretch of shoreline (Stallcup and Evens 2014, pers.

This finding suggests a plausible entryway of this gene into Antarctica from South America through the Atlantic or Pacific-American flyway, which are common routes used by shore birds, such as the ruddy turnstone, white-rumped sandpiper (Calidris
fuscicollis), and red knot (Calidris
