Graening finds Graeae horror beetle in California cave

Leptoferonia enyo

Pterostichus (Leptoferonia) enyo

Way back in ’07 I described a few new species of Pterostichus from California [1]. 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 [2] 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.

    Hello, I’m an Entomologist Italian, and study and collect as you Carabidae World, but also a second family, of the Anthicidae.
    I’m very interested kinds Anophthalmus or Microphthalmus (Duvalius, Typhlotrechus, Aphoenops, Orotrechus, Anophthalmus, Boldoriella, Trechus, Reicheia, Typhloreicheia, Anillinae, etc.)., of which I have a good collection.
    I have assets of about thirty publications (these if you are interested I can send you the PDF, but not all, some of them I only paper).
    You might be interested in an exchange of species, for this family ‘.
    If the answer is negative I could tell Entomologists interested?
    Thanks for your kind response.
    Best Regards
    Augustus Degiovanni

    P. S. Sorry for my bad English, but I’m board using a translator.
