Distribution of Tachysurus truncatus (+ others)

[Narelle]

Tachysurus truncatus

is listed in the Cat-E-Log as being distributed in "South and southeast Asia: Cambodia, Indonesia, Malaysia and Thailand."

The species was described from a locality in China, so this distribution is at least incomplete, but I am pretty certain they have not been recorded in any of these countries.

It looks like this information might stem from gbif, which has a list of specimens originally labelled Tachysurus truncatus that were later determined to be

Cryptarius truncatus

.
(Many Asian ariids were at one point placed in genus Tachysurus, family Tachysuridae, but the bagrids kept the name.)

Catalog of Fishes just lists the distribution of (true) Tachysurus truncatus as "East Asia: Yangtze River basin, China."

Based on the map, I believe there may be similar errors in other species in the genus. The genus Tachysurus is restricted to East Asia + Vietnam.
(For some reason

Tachysurus sinensis

has a CLOG map point in Africa?)

Thanks Narelle,

I've added the Yangtze to its distribution, but I don't know enough about the genus to prune every other entry yet. I'll leave that for the experts to inform more before I make additional updates.

Cheers, Eric

I can fix the issue with the occurrence in Africa. This happens when the body of water (in this case, the River Ma) doesn't have co-ordinates entered in the database.
