[Taxacom] A nomenclatural question

[a n]

Hi,
According to the Zoological nomenclature code how should a name be 
written if the original description written with incorrect genus spelling name? i.e. 
Lets say the 
Genus Megalytra Linnaeus, 1758 is 
already known and a new species was describe as

Megalytrus 
fieberi Puton, 1885

Should it be written with correct spelling 
like this:
Megalytra fieberi Puton, 
1885
or with parenthesis, like 
this
Megalytra fieberi 
(Puton, 1885)

I'll appreciate a reference to the code article,
Thanks
