[Entomology • 2019] Zelandoperla maungatuaensis • A New Flightless Stonefly Species (Plecoptera: Gripopterygidae) from Otago, New Zealand

Zelandoperla maungatuaensis Foster

in Foster, McCulloch & Waters, 2019.

A new wing-reduced species of the stonefly genus Zelandoperla Tillyard is described from Otago, New Zealand. Zelandoperla maungatuaensis sp. n. differs from a related species, Z. denticulata, primarily by lacking full wing development. We used morphological, geographical, and genetic evidence to assess the proposed status of Z. maungatuaensis sp. n. and Z. denticulata as separate monomorphic species, as opposed to conspecific members of a polymorphic species. High genetic divergence was found between distinctly allopatric populations, supporting the status of Z. maungatuaensis sp. n. as a distinct monomorphic species.
