Anacroneuria chavin Stark & Sivec 1998:16.
Holotype ♂( CASC). 67 miE Tingo Maria, Yurac, Peru
Material examined. Ecuador: El Oro, 9 miS Santa Rosa, 23 January 1955, E.I. Schlinger, E.S. Ross, 11♂( CASC).
Comments.Forewing lengths for these males range from 8-9 mmand the holotypeforewing length is 10.5 mm. This difference and subtle differences in the aedeagal apex suggest these specimens may represent a sibling species in this complex. Specifically, the narrow dark markings along the posterior shoulder margins are less distinct for the Ecuadorian specimens and the lateral margins of the aedeagal apex are not constricted at the shoulder as they are in the holotype. A larger sample from the type locality in Peruis needed to more fully evaluate the status of these specimens.
