De Carvalho, Claudio J. B. & Haseyama, Kirstern Lica F., 2018, A new species of Polietina (Diptera: Muscidae) from South America, with an updated phylogeny of the genus and a review of species’ identity in GenBank, Zootaxa 4407 (3), pp. 415-426 : 416-417

Polietina Schnabl & Dziedzicki, 1911

Diagnosis. Polietina can be recognized by the presence of three notopleural setae, the median reduced, and the setulose postalar wall. The male cercal plate has median and marginal spiny processes on the ventral surface, and the female has a strong proclinate fronto-orbital seta and a pair of interfrontal setulae; wings have M setulose ventrally from r-m to dm-cu, and the subcostal sclerite have two cilia (modified from Nihei & de Carvalho 2007).

Remarks. Nihei & de Carvalho (2007) keyed 13 Polietina species from 15 known at that time, except Polietina basicincta (Stein, 1904) and P. mellina (Stein, 1904) . These species were not included in the key because they were not recognized anymore, and the type specimens of both species (female specimens) were destroyed ( Pont 2013). Nihei & de Carvalho (2007) presented a brief diagnosis of both species based only in their original descriptions. Polietina species were studied by pattern-based biogeography with panbiogeographic track analysis (Nihei & de Carvalho 2005) and the Brooks Parsimony Analysis method (Nihei & de Carvalho 2007), and both indicated that the origin of the genus occurred in South America. Löwenberg-Neto & de Carvalho (2013) presented the checklist of the species of the genus with distribution data and Patitucci et al. (2013) found only Polietina orbitalis in Buenos Aires province ( Argentina). Haseyama et al. (2015b) presented new distribution records for P. bicolor Albuquerque, 1956 and P. orbitalis (Stein, 1904) . Recently, P. orbitalis was recorded for the first time in Colombia ( Uribe-Macias et al. 2010). The wing shape of this species is influenced by environmental variability ( Alves et al. 2016). In the most recent study on the phylogeny of Muscidae , it was corroborated that Polietina belongs to the subfamily Muscinae ( Haseyama et al. 2015a).

The species currently included in Polietina are as follows: Polietina basicincta (Stein, 1904) ; Polietina bicolor Albuquerque, 1956 ; Polietina concinna (Wulp, 1896) ; Polietina flavidicincta (Stein, 1904) ; Polietina flavithorax (Stein, 1904) ; Polietina major Albuquerque, 1956 ; Polietina mellina (Stein, 1904) ; Polietina minor Albuquerque, 1956 ; Polietina orbitalis (Stein, 1904) ; Polietina ponti sp. nov.; Polietina prima ( Couri & Machado, 1990) = Polietina nigra Couri & de Carvalho, 1996 , syn. nov.; Polietina rubella (Wulp, 1896) ; Polietina steini (Enderlein, 1927) ; Polietina univittata Couri & de Carvalho, 1996 ; and Polietina wulpi Couri & de Carvalho, 1997 .
