Modern Benoni

1. d4 Nf6 2. c4 c5 3. d5 e6

Old Benoni

1. d4 Nf6 2. c4 c5 3. d5 e5

It's whether the e pawn goes one square or two.

Could be either, depending on what happens next.

Modern Benoni

1. d4 Nf6 2. c4 c5 3. d5 e6

Old Benoni

1. d4 Nf6 2. c4 c5 3. d5 e5

It's whether the e pawn goes one square or two.
I suggest (but this is not a comprehensive treatment of the subject):

1 d4 c5 Old Benoni, sometimes called Schmid Benoni (as the young Lothar Schmid played it a lot.)

1 d4 Nf6 2 c4 c5 3 d5 e5 Czech Benoni. A current Wikipedia page on the Benoni calls this the Hromadka Benoni but that is not really correct. Czech theoretician Pachman in his 1960s book "Indian Systems" applied the term Hromadka System to all the 2...c5 lines but said 3...e5 "widely differs from the current variations of the Hromadka System." Bill Hartston's book on 3...e5 uses the term Czech Benoni.

Pachman chiefly considered 1 d4 Nf6 2 c4 c5 3 d5 g6/d6 but also:

1 d4 Nf6 2 c4 c5 3 d5 e6 which became the most popular version: Modern Benoni but Pachman didn't use that term.

1 d4 Nf6 2 c4 c5 3 d5 b5 Benko Gambit (originally called Volga Gambit)

1 d4 Nf6 2 c4 c5 3 d5 Ne4 (the "Vulture", christened by Stefan Buecker)

and there are some minor variants too (Lundin Gambit, Snake Benoni and also some other Buecker inventions)
