New species were discovered fairly quickly through research in South America. These included many species that probably fell into the family Loricariidae. However, science is not so quick to describe these fish. In 1988, the German aquarium magazine DATZ, therefore, proposed its own system to give the undescribed species a recognizable sign. Each non-described species for which photos and information were available received its own L-number. (The L stands for Loricariidae).
Later, the German aquarium magazine “Das Aquarium” came up with its own system, the LDA numbers.
What are L-Numbers?
L-numbers are fish from the family Loricariidae that have not yet been described. Officially, the number expires when they have been given a scientific name, but in practice the number sticks.
L-numbers expire after scientific description
If a species has been scientifically described, the L-number would in principle be dropped. In practice, names stick quite stubbornly, so that the L-numbers of already described species still stick. For example, the Hypancistrus zebra is still known to many people as the L046.
One specie multiple L-numbers
When officially describing the species, it appears that in some cases one and the same species has been assigned several L-numbers. Consider, for example, Baryancistrus xanthellus, which was assigned L018, L085, L177 and LDA060.
The fact that a species can receive several L-numbers is because fish species do not always look exactly the same. If populations become separated from each other due to changes in nature, for example, they may develop slightly different color patterns. They look slightly different outwardly, but that does not make them different species.
Abbreviations
In the list of undescribed species you often see a few abbreviations. Unfortunately, there is no scientifically established list of when to use which abbreviation. You only see these abbreviations for species that have not yet been described. They roughly indicate what the writer thinks the species is:
sp. = species – This species can probably be described as a separate species.
aff. = affinities – Has affinity with an existing species.
cf. = confer – Similar to another species.
Sometimes these abbreviations are also used interchangeably to complete the confusion.
