Cylindroiulus sagittarius (Brölemann, 1897)



ID Difficulty


A relatively well pigmented species with the telson produced into a stout pointed projection.

Confusion is possible with the ubiquitous Cylindroiulus punctatus (which occupies a similar dead wood habitat), but this later species bears a characteristic bulbous (club-shaped) tip to the projecting telson. 

A brief description, with figures, is given by Gregory & Owen (2019), who also note the occurrence on specimens of the ectoparasitic fungus Rickia laboulbenioides.
