Diagnosis.

The extinct species Plectrocnemia ohlhoffi sp. nov. is characterized by a pair of elongate inferior appendages, slightly diverging distally and slightly curved apically toward each other. The appendages are weakly concave mesally along their length. In ventral view, each appendage is rounded at the apex and slightly concave in shape apicolaterally, each with a subapical tooth and a weakly projecting apicomesal corner.

Etymology.

The fossil species is dedicated to Rainer Ohlhoff, who donated the type specimen to the Zoological Research Museum Alexander Koenig, Bonn, Germany (ZFMK) for permanent preservation.

Holotype.

♂; Myanmar, Kachin State, Hukawng Valley; exact locality unknown; Mid-Cretaceous Burmese amber inclusion; deposited in the amber collection of the ZFMK; former Rainer Ohlhoff collection; ZFMK-TRI000834.
