Parydra unicolor ( Becker, 1926)

Napaea unicolor Becker 1926: 102 ; type-locality: „ Russland “; holotype ♂ [ZMB, Mathis & Zatwarnicki 1995].

Primary type material examined:

1 ♀ holotype of P. unicolor in coll. ZMB with these labels: (1) “ Russland.”; (2) “unicolor / Beck.”; (3) “ Holotypus ”; (4) “Zool. Mus. / Berlin ” .

This species should be recognised by the characters given in the original description of Becker (1926): "Durch ganz gelbe Körperfarbe steht diese Art ganz ausserhalb des uns bisher bekannten Formenkreises dieser Gattung." However, the type specimen is an immature specimen of Parydra as previously mentioned by Krivosheina (1989). The record from the Czech Republic by Vaňhara (1981) may also be based on an immature specimen and is treated as doubtful (Kubátová-Hiršová 2003). Melecis et al. (2014) reported P. unicolor from Latvia but didn´t comment further on this remarkable record. Due to its immaturity and sex, it is not possible to identify the holotype and Napaea unicolor ( Becker, 1926) must be treated as a nomen dubium (status. rev.).
