This looks more like a Leucrocuta nymph to me (possibly L. hebe?).

Thanks, you're right on the genus for sure. There's no fibrilliform portion on gill 7, and the tails only have spines at the segments. I'd guess you're right on the species too but I don't know.

It's difficult to be certain of the species, Jason. If reliable keys to the nymphs exist, I haven't seen them, and McCafferty (2004) says that some of the species are "questionably valid."
