ABSTRACT
ABSTRACT The identities of the following four New World species of Stegana from Costa Rica, Stegana atrimana Malloch, 1924, Stegana nigrita Malloch, 1924, Stegana schildi Malloch, 1924, and Stegana tempifera Malloch, 1924, are clarified, and their redescriptions are provided. According to the original descriptions, the holotypes of the four species, deposited in the National Museum of Natural History (USNM), were males. However, upon dissection of their terminalia, we realized that all but one (S. tempifera) are females. Therefore, redescriptions of their external morphology (and/or terminalia) are mainly based on male paratypes, except for S. schildi, which is based on a male non-type specimen from Panama bearing Malloch's handwritten identification label. Photomicrographs of the habitus and terminalia, in addition to china ink drawings of the aedeagi and associated sclerites, are included.
