It's a good point. However, it's not just coral snakes and anacondas she's scared of, but anything which slithers along the ground or does a vaguely relaistic impression of a snake.
I often forget this, and recently found these delightful critters resting 'neath a slab in my garden:

Two slow-worms and a grass snake. Now, I'm daft enough to still get excited by these sorts of things and I then want to share my ebullience with the person I share the rest of my life. Hence my trotting happily over to her with two fistfuls of squirming captives.
It didn't go well. The shriek was audible in Tehran, and echoed around the fields and churches of our rural county for about an hour. Bats dropped out of the sky, stunned, whilst dogs ate their own ears.
Apparently, pointing out that slow-worms are legless lizards, not snakes, doesn't help, and niether does remonstrating with her for scaring them with her banshee wails.
I felt we both learnt something that day. She learned that she actually suffers from herpetophobia, not ophidiophobia, and I leaned that we have a very comfortable sofa to spend the night on.
