03938798AE219D4EFF0BFD1A8E04FE2C.taxon	etymology	Etymology. This species is named after Dr. Keith Credo, a business professor at the University of Louisiana at Lafayette and best friend of the first author, whose personal and professional support has been invaluable.	en	Owens, Brittany E., Carlton, Christopher E. (2017): A New Species of Pseudactium Casey (Coleoptera: Staphylinidae: Pselaphinae) From Tennessee, USA.

03938798AE219D4EFF0BFD1A8E04FE2C.taxon	diagnosis	Diagnosis. Pseudactium credoi is most similar to Pseudactium parabolicum (Brendel) and P. ursum in the form of the ventral projections of ventrite III extending beyond the lateral margins of the ventrite (Fig. 2). Pseudactium credoi differs from the other two species in the presence of a metacoxal spine and the absence of any other modifications to the meso- or metathoracic legs. The form of the aedeagus is also unique, with the broad sinuate median lobe and the accessory process modified into a series of flattened projections (Fig. 1).	en	Owens, Brittany E., Carlton, Christopher E.

03938798AE219D4EFF0BFD1A8E04FE2C.taxon	discussion	Comments. When using the dichotomous key to species of Pseudactium provided by Carlton and Chandler (1994), this species will run to couplet 9. Modifications to those made to couplet 8 (Carlton 1995) integrate P. ursum into this key. To distinguish P. credoi from P. ursum, further modifications to the remainder of the key are as follows:	en	Owens, Brittany E., Carlton, Christopher E.
