Tachys pulchellus LaFerte-Senectere, 1841
(syn. T. subtropicus Casey, 1918; syn. T. pugnax Casey, 1918) is best fit based on my passing this specimen through the outdated key by Casey (1918). Modern (revised) keys are not available. Only other species to consider in LA are T. litoralis and T. bradycellinus. Thanks Johnny for providing this photo-voucher now held in the P.W.Messer collection.

Genus Tachy here because elytron shows anterior discal seta located in 3rd stria. Also, 8th strial groove just behind middle shows little or no abrupt deviation medially.

Paratachys?
looks more like Paratachys, perhaps P. proximus, but I'm not familiar with southern species, and its a tough genus in any case
