Appears to be M. monica by range and the gonopods look identical to me. M. porrecta is the only one nearby afaik but it seems to be restricted to Kern cyn? Gonopods look very different imo
If they are M. monica I was surprised to see how bright the bioluminescence was. After ~10 min in a dark room it was possible to resolve details of individual rings, legs, antennae, etc. Variation across the range?
