(010/CEsco) Ceratophysella scotica (Carpenter & Evans, 1899)

*gotoi (Murphy, 1960)

Ceratophysella scotica is a common and widespread inhabitant of wet habitats, particularly Sphagnum bogs. It is easy to identify as the empodial appendage is longer than the claw and terminates in a fine filament which is easy to see, even in uncleared specimens (Fig. 1). 

Ceratophysella scotica belongs to the 'armata group' with setae p1>p2 on abd4 (Fig. 2).
