Found it had molted today, and he/she is a wonderful shade of blue for the time being. Can anyone tell if its diadema or variegatus?
This isn't always true. In the book "Whip Spiders" by Peter Weygoldt he plots male and female pedipalp tibia length vs carapace length, the difference isn’t as marked in D variegatus as it is in D diadema. D annulatipes demonstrates no sexual dimorphism when it comes to pedipalp-carapace ratios, however the figure in P Weygoldt's revision of the genus in 1999 would suggest that the male can grow larger than the female. D diadema has two spines on the ventral pedipalp trocanter, D variegatus only has one. You should easily be able to identify them on the skin with a magnifying glass (NB there will be a background of smaller spines but you should easily distinguish the larger spines). Try to get a copy of his paper if you struggle it contains very clear diagrams of the area of interest.I don't know how to ID Tail-less Whipscorpions but I believe there is sexual diamorphism by which the males have the greater (nearly ridiculous) elongate pedipalps
