That guy is really dark. It might be rivularis. It's definitely not torosa, but 'unken' has nothing to do with that. Torosa have a pale under-eye line, and the margin between ventral and dorsal coloration is very blurry. Granulosa have dark eyeliner, and a very sharp margin.
Rivularis, however, are usually very dark where torosa and granulosa are more mud-brown. You're also within range for rivularis.
