Qedty (ḳdty), The Two Nets, one of them would be Corona Australis is an Egyptian name, used in decan star clocks. Qed and Qedty were not present on RSC which used more appealing constellations further north such as Aped and Wia, respectively, to cover the same RA range.

Origin of Constellation
In the decan star clocks there are two decans called Qed, in singular, and Qedty, in dual. They are far away in RA. One possibly close to Pisces and before Aret, the other possibly to the South of Sagittarius. These are mentioned in NK celestial diagrams but never depicted as constellations.
Qed means net, so Qedty means two nets or a pair of nets, and hence you should be expecting they should have a nearly round, circular or enclosed form.
In a complete independent analysis, a tentative interpretation on these two decans was given by Belmonte (2003)[1] in MSAIT on the Decans, and simultaneously on his PUV book on "La Astronomía del antiguo Egipto" by Jose Lull in 2004. Both of us independently coincided in our hypothesis for Qed and Qedty after our analyses because they fit in RA within the errors. The pentagonal head of Cetus for Qed, and an area south of Sagittarius in which Corona Australis (quite circular) would be one of the pair Qedty.
So this, among others, is why we published our 2006 paper in JHA together. Table 4.7 is just a final count of 20 years of discussion and analyses.
Leitz (1995) locates Qed in Alpha Andromedae, which is far too north for a decan.

Religion/ Tales/ Mythology
As far as we know, there is not any mythological or cultural context for these two decans (asterisms) as we have for many other Egyptian stars and constellations apart from the utility and hour keepers in diagonal star clocks (which is indeed important).
IAU WGSN star name discussion
The name was suggested for a star in CrA in 2023. It is still under discussion.
