I am trying to understand Becker's 1912 German language revision of North American Chloropidae. Can "Brustseiten" be translated simply as "pleura" or does the word refer to a specific group of sclerites? Does it include the sternopleura? A couplet with "Sternopleuralfleck gelbrot" leads into another "Brustseiten ganz fleckenlos". Perhaps the Brustseiten are only the anepisternum and anepimeron in modern terminology.

Hello John,

As far as my German goes "brustseiten" is literally "sides of thorax". So yes, pleura and entirely I would think.

But as you point out that is not the case. Maybe he defines it somewhere, but in my experience those old keys might also be constructed completely wrong.

Kind regards,

Ectemnius

Hi John, I don't think Becker means a specific group of sclerites. Literally "Brustseiten" are the sides of the thorax - so you are right and it should simply be translated as "pleura".

Elsewhere in his paper I found the sentence "Brustseiten mit deutlichem schwarzen Sternopleuralfleck." So the sternopleura can be included.
