Advertisement I have a palladus or palladia, and a normal... but this one is near black-gray! Locale or variant name anyone?
It is Hadrurus arizonensis. Hadrurus spadix doesn't not have the crescent shaped 'mask'. Other Hadrurus sp like H. anzaborrego or H. obscurus have a different shaped 'mask'.
'pallidus' is nothing more than a pale arizonensis, it's very common wherever sand is pale. the darker arizonensis come from habitats with dark soil, like volcanic rock.
