Acerotella evanescens ( Kieffer, 1914 ) Masner 1964: 148 . Material examined Lectotype GERMANY1 ♀ (right of pin); Aachen ; A. Förster leg.; NHMW NHMW-HYM#0005406 . Paralectotypes GERMANY1 ♀ (same pin as lectotype); same data as for lectotype; NHMW NHMW-HYM#0005405 1 ♂ ; same data as for lectotype; NHMW NHMW-HYM#0005407 . Remarks Kieffer (1914) described several species based on a loan of Förster’s specimens from Vienna . However, he did not label these specimens. Their identity can be inferred from the locality (Aachen, or Aix-la-Chapelle in Kieffer’s French description) and often from a shared name, since Kieffer would use Förster’s nomina nuda as his own.
