PROC. ENTOMOL. SOC. WASH. 104(1), 2002, pp. 63-72 A REVIEW OF THE NEW RIODINID BUTTERFLY GENUS PANAROPSIS (LEPIDOPTERA: RIODINIDAE: SYMMACHIINI) Jason P. W. Hall Department of Systematic Biology — Entomology, National Museum of Natural History, Smithsonian Institution, Washington, DC 20560-0127. U.S.A. Abstract. — A new riodinid genus Panaropsis, tribe Symmachiini, is described and il-lustrated from Central and South America. Four species are recognized: elegans Schaus and semiota Bates transferred from Pterographiiim Stichel (n. comb.), and thyatira Hew-itson and inaria Westwood transferred from Esthemopsis C. and R. Felder (n. comb.)-Key Words: Esthemopsis, Neotropical, Pterographiiim, Panaropsis, Symmachiini The purpose of this paper is to describe and characterize a new riodinid genus in the tribe Symmachiini to provide a generic name for elegans Schaus 1920, semiota Bates 1868, inaria Westwood [1851] and thyatira Hewitson [1853], currently treated in Pterographiiim Stichel 1910 and Esthem-opsis C. and R. Felder 1865, for a forth-coming morphological survey of male an-droconia in the Riodinidae (Hall and Har-vey, in press). The tribe Symmachiini has been adequately diagnosed elsewhere (Har-vey 1987, Hall and Willmott 1996) and this information is not repeated here. Methods Dissections were made using standard techniques, after abdomens were soaked in hot 10% potassium hydroxide solution for approximately five minutes, and subse-quently stored in glycerol. The terminology for male and female genital and abdominal structures follows Klots (1956) and Eliot (1973). while nomenclature for wing ve-nation follows Comstock and Needham (1918). The taxonomic status of names is based on the catalog of Callaghan and La-mas (in press). All the collections listed by Hall (1999) were examined to determine the ranges of Panaropsis species.

Systematics Panaropsis Hall, new genus (Figs. 1-8, 9, 10-14, 15-17, 18) Type species. — Panara elegans Schaus 1920. Etymology. — The name alludes to the superficial similarity between members of the riodinine genus Panara and the type species elegans, which was formerly placed in Panara. Description. — Male: Forewing length 17-20 mm. Wing shape: both wings typi-cally somewhat elongate; forewing costa very slightly arched at base, distal margin
