Paracosmia (?) impennis Steinmann 1993: 134 [n. comb.] [ Mexico].

Type material. ♂ ♀ NHMUK (?) .

Known distribution. Mexico (endemic).

Distribution within Mexico. GRO: Mpty. Chilpancingo, Xocomanatlán [amended].

Notes. The original locality “Xucumanatlan” (sic) is amended to Xocomanatlán. The record made from material from SLP, Cueva de Carnierlas by A.B. Gurney in Elliott & Reddell (1973: 197) is considered doubtful; and the record to Costa Rica in Borelli (1903) and Sakai (2004) is erroneous. The species is very similar to the description of Paracosmia (?) gulosa (Scudder 1876) .
