Buenoa tarsalis Truxal, 1953: 1392–1395, fig. 49 [original description].
Diagnosis.
Medium to large species, male length 6.2–7.2 mm. Synthlipsis wide, ~ 1 / 2 of vertex width. Labial prong longer than third labial article, originating proximally on article. Fore femur with apex narrowed; stridulatory area oblong, with 17–23 ridges. First article of middle tarsus deeply emarginated.
Taxonomic notes.
Buenoa tarsalis resembles B. femoralis but has a very conspicuous emargination on the first article of the middle tarsus, which ensures its correct identification.
Note.
The most abundant and widespread species in this survey, present in all studied states.
