Ambidexter swifti Abele, 1972

Fig. 1 A–B

Ambidexter swifti Abele, 1972: 366 , figs. 1–3.

Material examined. Panama: 2 ov. females (pocl 5.5, 6.0), OUMNH.ZC. 2009-18 -012, Chumical, mixed rocksand intertidal exposed at night, tide pool, leg. A. Anker, 17.04.2007.

Colour pattern. Cephalothorax and abdomen generally transparent, with numerous red-brown chromatophores, larger on cephalothorax than abdomen; third maxillipeds and first pereiopod also covered with chromatophores, posterior pereiopods transparent ( Fig. 1 A–B).

Remarks. The specimens present no noteworthy features and correspond closely to the type description by Abele (1972).

Ecology. The ecology of A. swifti is relatively poorly known. The majority of specimens reported in Abele (1972) were collected from burrows on a mid-tidal, sandy beach. The present specimens were collected in a similar habitat (rock-sand shore); however, they were dwelling in tide pools at night.

Distribution. According to Wicksten & Hendrickx (2003) the species is distributed from San Diego, California southwards to Panama, also occurring in the Galapagos Islands. However, records are very sparse throughout its range.
