Epameibaphis Oestlund

This is a genus for a handful of species that feed on various sagebrushes (Asteraceae: Artemisia) in North America.  It is remarkably similar to Pseudoepameibaphis except for the shape of the siphunculi being straight with an apical knob or swelling, as opposed apically curved in Pseudoepameibaphis.  Apart from this difference, the two genera have almost identical morphology, down to setal numbers, shapes, patterns, antennal morphology, etc.  I have no decent photos of this genus, but I thought I would add a page due to all the work I’ve put into it in the past few years.  Also, I finally decided to put species names on about half my slides, which decision was reflected in 2018 release of the slide collection database.

Based on study of my specimens in winter 2017 and again in winter 2018 and 2019, there are definitely at least 4 species of Epameibaphis.  There are currently 3 generally accepted species, E. atricornis, E. frigidae, and E. utahensis. I have decided that recognizing the first two of these is possible, but am still not clear on what E. utahensis is.  One of the groupings of specimens in my collection is almost certainly E. utahensis.  Correct identification will probably require examination of the original types.  In addition, I have one or two species with distinctly clavate siphunculi (reminiscent of Cachryphora), plus what might be a pale form, or relative, of E. atricornis.  I hope to some day have gathered enough material to publish a good review of the genus.
