Ambidexter panamensis Abele, 1972

Fig. 1 C

Ambidexter panamensis Abele, 1972: 373 , figs. 4–5. —Hendrickx, 1988: 246.

Material examined. Panama: 1 female (pocl 3.3), OUMNH.ZC. 2007-13 -015, Chame Bay, exposed mud flat, burrow, suction pump, leg. A. Anker et al., 0 7.10.2006.

Colour pattern. Body largely transparent, with sparse red chromatophores on cephalothorax and abdomen, pereiopods transparent ( Fig. 1 C).

Remarks. The specimen presents no noteworthy features and corresponds closely to the type description by Abele (1972).

Ecology. The ecology of A. panamensis is known rather insufficiently. Abele’s (1972) specimens were collected from sandy tide pools. Wicksten (1983) equally reported specimens from tidal pools, but also included a single specimen dredged from 65 m. The present specimen was collected with a suction pump on an intertidal mudflat, but it remains unknown if the shrimp was dwelling inside a burrow of an unidentified burrowing host or in its own shelter in the vicinity of the burrow.

Distribution. According to Wicksten & Hendrickx (2003) the species is distributed from Baja California southwards to Panama, also occurring in the Galapagos Islands.
