A new and a previously known species of the genus    Zhenia    Q. Zhang, 2016 (  Eremochaetidae  ) are illustrated and described based on two males and a female in amber:    Zhenia   burmensis    sp. nov.  and    Z.   xiai    Q. Zhang, 2016. The male    Z.   xiai    is the first male of this species recorded. The relationships of   Archisargoidea   (including   Eremochaetidae  ,    Zhenia   ) are reassessed based on male genitalia. The superfamily is more likely related to the   Stratiomyomorpha   than to the   Muscomorpha   (including   Nemestrinoidea  ). The components and structures of the ovipositor are re-illustrated. The results of our comparative study demonstrate that the ovipositor of    Zhenia    is similar in shape and detail to that of    Rhagoletis   pomonella    (Walsh, 1867) (  Tephritidae  ). This study concludes that the ovipositor of    Zhenia    is most likely formed from abdominal eighth and ninth segments instead of the cerci, as a previous study found.
