Unknown Stinging Slug Caterpillar

Dear Mike,
This is definitely a Stinging Slug Caterpillar in the family Limacodidae, but we are uncertain of the species.  The red color is quite unusual.  We believe it might be a Crowned Slug Caterpillar,
Isa textula, which is pictured on BugGuide, but we cannot locate any images of red individuals.  Sometimes caterpillars change colors right before metamorphosis.
