Epameibaphis<\/em> Oestlund<\/strong><\/p>\n\n\n\n

This is a genus for a handful (or two) of species that feed on various sagebrushes (Asteraceae:\u00a0Artemisia<\/em>, some species placed in Seriphidium<\/em> by some specialists) in North America.\u00a0 It is remarkably similar to Pseudoepameibaphis<\/em> except for the shape of the siphunculi being straight with an apical knob or swelling, as opposed to apically curved in Pseudoepameibaphis<\/em>.\u00a0 Apart from this difference, the two genera have almost identical morphology, down to setal numbers, shapes, patterns, antennal morphology, etc.\u00a0 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 several years. Since moving to Colorado in 2021, I have made many new collections of this genus from some new host plants (e.g. Artemisia nova, Artemisia bigelovii<\/em>, and what I’m calling Artemisia tridentata parishii<\/em>). It’s interesting that Epameibaphis<\/em> as a group is more common than Pseudoepameibaphis<\/em> in Colorado, whereas Pseudoepameibaphis<\/em> is the more common group in the northwestern states. <\/p>\n\n\n\n

In February of 2026 I wrote a short review essay about the group<\/a>. In it, I wrote of what I think are 8 species total in my collection. I also caution that intensive collecting work in places I have rarely visited would likely turn up even more diversity in this genus.<\/p>\n\n\n
