Pterostichus - Pterostichus relictus

Pterostichus - Pterostichus relictus
Whitley County, Kentucky, USA
June 21, 2005
Size: 18 mm
Pterostichus, species unknown. Elytra not iridescent, two discal punctures, tarsomere 5 glabrous beneath. (Maybe P. relictus ???)

Moved from Pterostichus.

Pterostichus relictus is a good bet
as I have a similar specimen from PA I call P. relictus. My notes say P. relictus can have 1 to 3 dorsal punctures on each elytron. Most like rare indidviduals of P. stygicus without ventral tarsal setae. Latter is more iridescent, pronotum with distinct carinae at hind angles and laterobasal depression with tubercle. Janet Ciegler (2000) distinguishes the two in part by number of setae on hind coxae (perhaps true in SC) but as Robert Davidson recently pointed out to me, not reliable elsewhere. P. relictus is known in IN per Bousquet & Larochelle (1993).

I collected two of these, the other is somewhat teneral. They didn't really look much like the P. stygicus I have, which is what I initially believed they were.

What are your thoughts on this specimen?
