Tachys austinicus
Casey, 1918
Tachys austinicus is a small ground beetle in the Carabidae, first described by Casey in 1918. It belongs to the large Tachys, which comprises numerous diminutive carabid beetles often associated with moist . The was originally described under the genus Paratachys, which is now treated as a subgenus of Tachys. Like other members of this genus, it is likely to be found in leaf litter, soil, and other ground-level microhabitats, though specific ecological details for this species remain poorly documented.

Identification
Tachys austinicus can be distinguished from other Tachys by subtle morphological characters, particularly features of the , pronotum, and male genitalia. Species-level identification in this typically requires examination of microscopic characters and is not reliably accomplished through field observation alone. The subgenus Paratachys, to which this species belongs, is characterized by specific combinations of elytral striation patterns and pronotal shape, though these features require taxonomic expertise to interpret.
Distribution
Recorded from the United States (USA) and North America. Specific locality data within this range is sparse based on available records.
