This little fella is one of the new ones, really liked the spines, which reminds me of a mature mans chesthair :) It’s labeled Neoporteria nidus v. gerocephala which seems about right? Presumably, gerocephala from the ancient Greek, meaning old head? γηρο- (gero-) being old, κεφαλή (kephale) being ...
