Perigenes constricta. (I've seen listed as constricta and constrictus, not sure which it should be. Will go with

Thanks Chuck. I agree with you. I didn't realize I could change the name after making the page.

I vote for constrictus
This issue has been debated before- at length. Nearctica, like many checklist-type sites, matches gender with the original genus in hopes of keeping the spelling of the specific epithet consistent in spite of nomenclatural changes. The ICZN dictates matching gender with the current genus, and the authoritative sites like ITIS follow it.

Advocates of the former approach say that strict adherence to the ICZN should be set aside in this one case to make it easier for the general public- who don't know how to convert from one Greek or Latin gender to another- and for finding things with search engines.

I would contend that gender confusion will be everywhere no matter what sites like ours do, so we might as well go with the official standard. Of course, I'm just an amateur with no entomological training and the advocates of the other view are often taxonomists or other recognized experts, but there are plenty of experts here who would agree with me.

Whichever way you decide, there's no reason to make a new guide page over a spelling change: the correct procedure is to edit the existing guide page and (unless it was a simple typo) put the other spelling in the Synonyms field so both spellings will turn up in searches.
