Carmine-Tailed Janberry is indeed a lotto from the Tonberry Imprecators (hard not to call them Impregnators....).
The trick to the area is, there are actually two placeholders, only one of which will be up at a given time.
Focus on the Tonberries in the G-9 area. In this area, there are three possible Imprecator spawns, only two of which will be up -
~ At the north border of G-9, there will be either one or two Imprecators and a Trailer closeby. If there are TWO Imprecators up, ONE of them is the placeholder.
~ Near the mouth of the tunnel going west, there is a little hut with another Trailer closeby, and another possible Imprecator.
If this Imprecator is present, IT is the placeholder.
~There is also an Imprecator in the tunnel itself, around F-9. This is NOT a placeholder, nor are the two near the Sacrificial Chamber gate, nor the one near the mouth of the NE tunnel going to the upper floor.
Basically, when you get to G-9, you'll find one of two scenarios:
2 Imprecators north of the tunnel mouth, or
An Imprecator to the North, and another near the hut East of the tunnel.
The third possibility is that only one Imprecator will be up, in which case either someone else recently killed one, or the NM is up wandering around the area.
