- Abstract
Background: The chirostylid squat lobster, Chirostylus dolichopus Ortmann, 1892, was rediscovered from its type locality, Katsuyama (Boso Peninsula, Honshu, Japan) (35°06.7'N, 139°48.8'E), since the holotype had been collected in 1880. The colouration in life of C. dolichopus is reported for the first time on the basis of a recently captured topotypic specimen. Results: Chirostylus dolichopus is characterized by the brilliant yellow ground colour and spot pattern on the meri of the ambulatory pereopods. Conclusions: The colouration in life of C. dolichopus is diagnostic for species of Chirostylus. The examination of the present specimen revealed that C. dolichopus is distinguishable from other shallow water congeners, such as C. ortmanni, C. sandyi, and C. stellaris, by the colouration as well as morphology.
