As the customization guide states, the LatexParam will be output as is
after all LaTeX Arguments.

You can add the extra curly brackets to the LatexName, e.g.,

Style myenv
    LatexType             Environment
    LatexName             myenv}{
    Argument              1
            LabelString    "entry 1"
            AutoInsert    1
            LeftDelim "<br/>["
            RightDelim "]"
    EndArgument
End

Or you can add a second argument:

Style myenv
    LatexType             Environment
    LatexName             myenv
    Argument              1
            LabelString    "Something"
     Mandatory    1
    EndArgument
    Argument              2
            LabelString    "entry 1"
            AutoInsert    1
            LeftDelim "<br/>["
            RightDelim "]"
    EndArgument
End

But my approach feels a bit hackey.
Maybe someone else will have a better
solution.
