Remarks.

Chimerothalassius belongs to the subfamily Parathalassiinae which is considered the sister group to the Dolichopodidae sensu stricto ( Sinclair and Cumming 2006; Brooks and Cumming 2011). Chimerothalassius runyoni was known from one female specimen and a slide-mounted wing collected in Dominica during the Bredin-Archbold-Smithsonian Biological Survey and was formally described after males were collected on Montserrat in 2017 ( Brooks and Cumming 2018). This species occurs on rocky or stony intertidal zones.
