Abstract

Male adults and pupae of the genus Lopescladius from the Nearctic are reviewed. The morphologies of adult male and pupal Lopescladius (Cordiella) hyporheicus Coffman and Roback, 1984, are reexamined and compared to the Neotropical Cordiella. The pupa of Lopescladius (Lopescladius) inermis Sӕther, 1983, is described, along with comments on the adult male. Three additional pupal morphotypes are described. Keys are included for adult males and pupal exuviae from the Nearctic. Large range expansions are reported for several species.
