I was wondering if there was a list of the Lua names of all new biters/spitters/spawners/worms/hives. I looked through the code but could not find any. I am trying to add compatibility with https://mods.factorio.com/mod/DropSciencePack.

The name is determined by the formula:
faction .. "-" .. unit .. "-v1-t" .. lvl .. "-rampant"
where
faction - faction name: neutral, acid, laser, fire, inferno, wasp, spawner, electric, physical, troll, poison, suicide, nuclear, energy-thief, fast, juggernaut, arachnids
unit - unit type (biter, spitter, worm, spitter-spawner, biter-spawner, hive)
lvl is entity level (1-10)

example: "neutral-biter-v1-t10-rampant", "nuclear-biter-spawner-v1-t5-rampant"

Not all factions have biters
Not all factions have spitters
what faction has is specified in constants.lua (line 609)

the names are completely the same as the Rampant, but the last two factions are not there
