Entomology (Study of Bugs)/scorpion Serradigitus species


24 October 2013
I'm hopping to find out the Keys to 4 scorpion species.They are…
Serradigitus gramenestris (Williams, 1970)
Serradigitus joshuaensis (Soleglad, 1972)
Serradigitus subtilimanus (Soleglad, 1972)
Serradigitus gertschi (Williams, 1968)
I'vs been trying to locate illustrations or photos that will show me details of their pedipaps (arm & claws). Any detail of the fixed and moveable fingers of the chela (claw, hand, finger) would be most helpful. Also the metasoma with telson (tail & stinger). I'm hopping for dorsal, lateral, ventral aspects (top, side, bottom). I hope i'm not asking too much. Any help is deeply appreciated. Thank you.

Dear Mr. Meitz - This is a question for a scorpion specialist, which I most certainly am not! About all I can do is refer you to the following page on the systenatics of the genus Serradigitus - - and suggest that you contact current researchers on this group, such as at and

My apologies for not being able to be of more direct assistance,

Will accept most questions in general entomology, including those related to medical entomology, taxonomy, ecology, arthropod surveillance, and pest management. If you are requesting a 'mystery bug' identification, PLEASE either attach an image to your question, or post an image on a web page (such as Flickr) so that I can look at it, as verbal descriptions frequently are insufficient for a definitive identification.
