Polietina Schnabl & Dziedzicki, 1911 View in CoL View at ENA

Polietina Schnabl & Dziedzicki, 1911: 218 View in CoL . Type species: Aricia pruinosa Macquart, 1846 [preocc. Aricia pruinosa Zetterstedt, 1845 ; = Mydaea concinna Wulp, 1896 ].

Diagnosis. Colouration yellowish-brown to blackish-brown with silver pruinosity; wing with maculae or infuscate on apex of Sc and R1, on apex of R2+3, and on r-m and dm-cu crossveins. Female with proclinate fronto-orbital seta ( Figs. 1–2 View FIGURES 1 – 8. 1 ); parafrons weakly setulose on upper half; interfrontal seta present ( Fig. 2 View FIGURES 1 – 8. 1 ). Dorsocentrals 2+3-4. Postsutural intra-alars 2; intrapostalar absent. Notopleurals 3 (one additional median, shorter than the usual two setae). Prosternum setulose. Katepisternals 1+2. Meron setulose. Postalar wall setulose ( Fig. 12 View FIGURES 12 – 14 ). Anterior suprasquamal ridge usually setulose. Wing with the apical portion of stem-vein usually setulose dorsally and ventrally; R1 setulose dorsally; Rs node and R4+5 setulose dorsally and ventrally; M setulose ventrally between r-m and dm-cu crossveins; M straight, subparallel to R4+5. Lower calypter glossiform ( Fig. 12 View FIGURES 12 – 14 ). Subcostal sclerite setulose ventrally. Calcar strong. Mid tibia with a strong submedian seta on ventral to posteroventral surface.

Comments. A cladistic analysis supporting the monophyly and indicating the phylogenetic relationships among the species of Polietina was performed by Nihei and de Carvalho (2007b). Furthermore, its monophyly and the major relationships were recovered by the multi-gene analyses of Schuehli et al. (2007).

Distribution (15 species). Nearctic (southern USA) and Neotropical.
