Pseudouroctonus reddelli (Texas Cave Scorpion) ?

This is the same one that I caught inside the house.

One of the more interesting vaejovids, both ecologically and taxonomically, is Pseudouroctonus reddelli (Gertsch & Soleglad 1972), a relatively large, dark-colored species distributed throughout much of central Texas (Gertsch & Soleglad 1972 ; Stockwell 1986). As with other vaejovids, individuals may be found under surface debris such as rocks or logs. However, P. reddelli is unusual in that it is troglophilic, with the majority of specimens having been captured from caves (Gertsch & Soleglad 1972; Stockwell 1986) despite the lack of any obvious adaptations for cave dwelling (such as lack of eyes or pigmentation, or elongated appendages) as seen in troglobitic scorpions. (Brown 1997)
