Iphthiminus serratus is a species of darkling beetles in the subfamily Tenebrioninae.[1] Originally I. sublaevis and I. salebrosus were considered subspecies of I. serratus due to minor geographical variation, but this variation is gradual and they are now considered synonyms.[2]

Appearance edit

They are differentiated from the other species of Iphthiminus as they have only a moderately wrinkled prothorax with moderate serrations of the lateral edges.[2]

Distribution edit

This species is present primarily in the North Pacific, including California, Idaho, Nebraska, Nevada, New Mexico, Oregon, Washington, Wyoming, and British Columbia.[2]

Diet and habitat edit

Like other darkling beetles in the genus Iphthiminus, I. serratus is associated with rotting coniferous logs, especially pine wood.[2] When raised in captivity by the Invertebrate Dude, I. serratus was observed eating chick feed and rotting wood[3]
