Cormocephalus is one of the few Scolopendromorpha-geni that is not easy to identify, cause there is still a lot of confusion in taxonomy literature.
Furthermore they are rare in the hobby and look astonishing (especially maxillipeds and ventral terminal legs of some species). I'm still sure a lot of unidentified Cormocephalus live in unexplored Magadascar (regarding invertebrate-identification).
Some Cormocephalus-species are able to spray an acid-like secretion when they are disturbed (Lewis mentioned it on Cormocephalus nitidus).
Never made the experience for myself, but i guess Steven told me once he became a victim of his nitidus.
That all makes them one of the most interesting Scolopendromorpha to me.
They are no giants and sometimes very small (3cm up to 14cm), but size doesn't matter to me.
