Holotype ♂ : BOLIVIA : La Paz : Unduavi , 16°19'S 67°54'W , 3500 m , moss, 5–17 Apr 2001 , S.A. Marshall , debu00208763 ( UASC ) . Paratypes : same data as holotype ( 2 ♀ , DEBU , UASC ); as above but grass, pan traps ( 2 ♀ , DEBU , UASC ) . Comments. The species name is derived from the type locality and should be treated as a noun in apposition.
