ID Confirmation - Cymaenes trebius
I sent your image to Dr. Andrew D. Warren - who is one of the authors of the Butterflies of America website.
He confirmed the identification of Cymaenes trebius.

The binomen Cymaenes trebius is what is listed in (1).
The BugGuide site has this species posted as Cymaenes odilia.

In my opinion - Cymaenes trebius
See Butterflies of America - Cymaenes trebius
Glassberg in a "Swift Guide to the Butterflies of Mexico and Central America" refers to the upper spot of the median band on the underside of the hindwing as being a violet square in what is Cymaenes odilia in his book on pg. 218.
In this same book Glassberg notes that in Lerema accius - there are white dashes on the costal margin of the forewing above the subapical spots.
See this field mark in Butterflies of America - Lerema accius

However I am definitely not an expert in the identification of this species - C. trebius.
I am familiar with and have seen lots of L. accius and at least to me your skipper looks too intricately patterned to be this species.
