They were. I have the Baensch Aquarium Atlas Vol. 1, 1st edition from 1987. Almost all CAs and a lot of northern SAs were in Cichlasoma. There were a lot more species in the genus Acara as well, which has been divided up as much as Cichlasoma. At that time it was believed there were only three species of Cichla (peacock basses) as well. Most of the Lake Malawi haps were in the genus Cyrtocara and probably 90% of mbuna were in Pseudotropheus. Most of the Tanganyikan substrate spawners were in Lamprologus, as well as a large number of river dwelling species from Central and East Africa. Peacocks have mostly all stayed in Aulonocara, but there were only a handful of species compared to today; now there are dozens. And there were dozens of species of East African cichlids just thrown in Haplochromis. Astatotilapia was just starting to absorb some of them. These were all just waste basket taxons where species were thrown as a general classification until furter refinement of their genus and species statuses could be narrowed down further. Times have changed.
