Way back in ’07 I described a few new species of Pterostichus from California . All of them had reduced eyes, small body size, and each from limited series of specimens. Although I have personally collected nearly every species of the subgenus Leptoferonia a few have eluded me and most are among these beetle. Three of these I named for the Graeae  and one, enyo or “horror” was known only from a single female collected by Lee Herman (AMNH). I knew exactly where Lee had collected in Trinity County near Helena, and went there at least five times, at different times of the year, but alas, no luck.
Fortune has now smiled and Geo Graening, a spelunker and ispod fancier, collected a second specimen, a female again, from Paul Gibson Cave about 10km north west of the type locality. The specimen is in EtOH and now plan to test my hypothesis that this is sister to Pterostichus (Leptoferonia) humilis, a common fog-belt species to the west.
