Comment(s) on data
D. dearmatus vs D. jacquesi, comment D. Rahayu, Septembre 2017: Following your discussion (Jannes Landschoff) with Joseph (J. Poupin) on Dardanus dearmatus and D. jacquesi, I agree with your opinion in the remark for your South African specimen (perhpas D. jacquesi but color similar to a Marquesan sp. attributed by Rahayu to D. dearmatus). Unfortunately I do not have any colour photo of life D. dearmatus. When I identified Joseph photograph as D. dearmatus I was counting on my memory of the live colour of D. dearmatus I collected in Ambon Bay, Moluccas, Indonesia long time ago. The specimen and photos I took was destroyed together with my laboratory during the riot in 1999. I examined D. dearmatus from Paris Museum that I have with me, and I see that the left cheliped palm of dearmatus is almost smooth ( vs tuberculate in D. jacquesi). Maybe you can just add this in the remarks.
