Genus Bothrotes
Explanation of Names
Bothrotes Casey 1907
2 spp. (with sspp.) in our area, a dozen more in Mesoamerica(1)
9-15 mm
females have ridged pronotum
neotropics north to CA-SD-WI-NY(1)
open habitats; adults on vegetation, may come to lights
There's strong sexual dimorphism in most species of Bothrotes. Only the females have the pronounced pronotal elevations, which makes Freude's key(2) not too helpful for keying out males. Unless genitalia are shown, I think most BG images of males will have to be left at genus level. --Jason Botz, 28.x.2016
