Lua On kill a original copy

[nefinoo]

Explanation of the script: It makes that when some of these bosses die, a green tp (id: 25417) appears replacing the blue one (id: 1387), and takes you to the destination (godbreakerPos).

local bosses = {
    ['jadeite'] = {teleportPos = Position(16899, 16501, 7), godbreakerPos = Position(16893, 16502, 8)},
    ['nephrite'] = {teleportPos = Position(16893, 16499, 8), godbreakerPos = Position(16895, 16501, 9)},
    ['zoisite'] = {teleportPos = Position(16895, 16503, 9), godbreakerPos = Position(16905, 16497, 10)},
    ['kunzite'] = {teleportPos = Position(16906, 16498, 10), godbreakerPos = Position(16860, 16496, 10)},
    ['queen beryl'] = {teleportPos = Position(16868, 16495, 10), godbreakerPos = Position(16817, 16496, 10)},
    ['queen metalia'] = {teleportPos = Position(16825, 16495, 10), godbreakerPos = Position(16817, 16496, 10)}
}

local function revertTeleport(position, itemId, transformId, destination)
    local item = Tile(position):getItemById(itemId)
    if item then
        item:transform(transformId)
        item:setDestination(destination)
    end
end

function onKill(creature, target) 
    local targetMonster = target:getMonster()
    if not targetMonster or targetMonster:getMaster() then
        return true
    end

    local bossConfig = bosses[targetMonster:getName():lower()]
    if not bossConfig then
        return true
    end

    local teleport = Tile(bossConfig.teleportPos):getItemById(1387)
    if not teleport then
        return true
    end

    if teleport then
        teleport:transform(25417)
        targetMonster:getPosition():sendMagicEffect(CONST_ME_THUNDER)
        teleport:setDestination(bossConfig.godbreakerPos)
        addEvent(revertTeleport, 60 * 1000, bossConfig.teleportPos, 25417, 1387, teleport:getDestination())
    end
    return true
end

I have this script, and have 2 monsters name 'Zoisite' in the lua file, but on .xml file one name 'zoisite' and another 'zoisite2', and I want to make when killing zoisite (in this case the original) the teleport appears (id: 25417) and takes you to the destination (godbreakerPos = Position (16905, 16497, 10)).
but my problem is when u kill any 'zoisite' on the map, the tp appears.

After confirming that it is the correct creature name, confirm if the creature is within a specified area.
