Nun ja, dass Seitschrift ist ja auch nichts…. Abmachen!
And so we go on. But who cares? Not you...

Great! I've got it today! And now reading....
Yesssssssss!
That is how science in the jungle is mostly done…. sitting and waiting...
Seifert 2018 ist zehr gutt!
It is an original edition. It will be followed (when?) by a book about all ants of Europe...
A few days ago the website got from 12/06 to 18/06 as publication-date... and it changed its website.
Now it is in this site: https://knnvuitgeverij.nl/arti…ds-mieren-van-europa.html
But that is not all… On 13/06 it became available. So I ordered it and now it is waiting...

When do we know an ant is an extreme, workerless inquiline?
From Chapter 12:
1. The worker caste is lost.
2. The queen is either replaced by an ergatogyne, or ergatogynes appear together with a continuous series of intergrades connecting them morphologically to the queens.
3. There is a tendency for multiple egg-laying queens to coexist in the same host nest.
4. The queen and male are reduced in size, often dramatically so; in some cases (for example, Teleutomyrmex schneideri, Plagiolepis ampeloni, Plagiolepis xene) the queen is actually smaller than the host worker.
5. The male becomes “pupoid”: its body is thickened, the petiole and postpetiole become much more broadly attached, the genitalia are more externally exposed when not in use, the cuticle becomes thin and depigmented, and the wings are reduced or lost. The extreme examples of this trend are displayed by Anergates atratulus, Pheidole neokohli, and Pheidole acutidens (see Figures 12-19 and 12-20).
6. There is a tendency for the nuptial flights to be curtailed, and to be replaced by mating activity among nestmates (“adelphogamy”) within or near the host nest. Dispersal of the queen afterward is very limited.
7. Probably as a consequence of the curtailment of the nuptial flight just cited, the populations of inquiline species are usually very fragmented and limited in their geographic distribution.
8. The wing venation is reduced.
9. Mouthparts are reduced, with the mandibles becoming smaller and toothless and the palps losing segments. Concomitantly, the inquilines lose the ability to feed themselves and must be sustained by liquid food regurgitated to them by the host workers.
10. Antennal segments are fused and reduced in number.
11. The occiput, or rear portion of the head, of the queen is narrowed.
12. The central nervous system is reduced in size and complexity, usually through reduction of associative centers.
13. The petiole and postpetiole are thickened, especially the latter, and the postpetiole acquires a broader attachment to the gaster.
14. A spine is formed on the lower surface of the postpetiole (the Parasitendorn of Kutter).
15. The propodeal spines (if present in the ancestral species) “melt,” that is, they thicken and often grow shorter, and their tips are blunted.
16. The cuticular sculpturing is reduced or lost altogether over most of the body; in extreme cases the body surface becomes strongly shining.
17. The exoskeleton becomes thinner and less pigmented.
18. Many of the exocrine glands are reduced or lost, a trait already described in some detail in the earlier account of Teleutomyrmex schneideri.
19. The queens become highly attractive to the host workers, which lick them frequently. This is especially true of the older, physogastric individuals, and it appears to be due to the secretion of special attractant substances which are as yet chemically unidentified.
