Abstract
Two malacostracan crustacean genera are described from the Langsettian (upper part of the Bashkirian, Lower Pennsylvanian) of the Scottish coal fields in the Midland Valley of Scotland. One is the youngest occurrence of
Tealliocaris
Peach, 1908
and was found at Polkemmet Colliery near Whitburn, West Lothian. It is recognized as a new species,
Tealliocaris elliotti
, based on the presence of eight spines on its scaphocerites and lateral convergent carinae of the telson. The other crustacean is a unique specimen from the Ardenrigg Colliery at Wester Bracco, North Lanarkshire in similar shales of Langsettian age. There are no distinguishing characters preserved that would identify it as a new species, but it can be placed in
Palaeocaris
Meek and Worthen, 1865
based on the well-preserved features of the tail fan. This is the first record of this genus in Scotland, although specimens of
Minicaris brandi
Schram, 1979
from the Namurian (Serpukhovian, Upper Mississippian) shales of Bearsden are now here also considered to be a species of
Palaeocaris
.
