Although the names are listed as synonymous, the animals they are describing are not the same. Blaberus atropos belongs to the "Atropos" group, whereas Blaberus fusca, is most DEFINITELY not a member of this group, and, although not listed in Roth's Blaberus genitalia paper, probably belongs in the "Giganteus" group.
I will probably get to doing some dissections tonight and seeing which group it is placed in; I'm 99.99% positive "Blaberus fusca," known as "Ugly Brown Blaberus craniifer" in Europe, is an unrelated species (outside the fact they share a genus) to the actual Blaberus atropos, which is a smaller species that is similar to Blaberus discoidalis.
I also doubt that Blaberus fusca and Blaberus craniifer are the same species; Just yesterday I found a considerably dark Blaberus fusca that essentially had the coloration of Blaberus craniifer; however, one look at the shape of the tegmina, body proportions, and the overall length of the individual made it stand out distinctly as what it was.
