[Taxacom] abbreviation in authority citation

[Max BILLAH]

Diana,

A check on the species shows that it was transferred from Isotoma to Proisotoma by Börner in 1903.
My guess is that the abreviation t.t may or might mean "transferred by" (just a guess!).

Cheers,

Max BILLAH.

  Dear all,
  Does anybody know the meaning of "t.t" in the authority of a species?

  An example could be a collembola 
  species:  Proisotoma minuta (Tullberg, 1871, t.t.) Börner, 1903
  I would like to know what is it and if 
  abbreviating the authorship which author could be excluded?

  Thanks in advance
