Megistopoda aranea: Wenzel et al., 1966: 541-542 . Material examined: Misiones : Estancia Prates , Barra Concepción , 28°05′S , 55°32′W , 05.iii.2011 , 1 ♀ ( CMLA 725 ) and 1 ♂ ( CMLA 726 ) on Artibeus fimbriatus ( FMI 271 ) ; 27.iii.2011 , 1 ♀ ( CMLA 728 ) and 1 ♂ ( CMLA 727 ) on A. fimbriatus ( FMI 285 ) ; Parque Provincial Teyú Cuaré , 27°17′S , 55°35′W , 11.xii.2009 , (4) 2 ♀ ( CMLA 732 , 733 ) and 2 ♂ ( CMLA 730 , 731 ) on A. lituratus ( FMI 151 ) ; Reserva Ecológica Tupá Puojhá ( Fachinal ), 27°37′S , 55°43′W , 30.iv.2010 , 1 ♀ ( CMLA 729 ), on A. fimbriatus ( FMI 20 ) . Identification: This species is easily distinguishable from M. proxima by its long and narrow wings with two veins that unite with the costa; very long legs, including a hind femur nearly as long as the entire body; prescutum with very weak setae along the median suture; and lateral margins along the longitudinal membranous suture that include one or two stronger setae. Comments: This species had only been previously identified in one locality in Corrientes province (Autino et al., 2009) and several in Misiones, having recently been cited for the Osununú-Teyú Cuaré AICOM (Area of Importance for the Conservation of Bats) (Autino et al., 2018). It has also been cited for some localities in the northwestern Argentina ( Jujuy , Salta and Tucumán ) (Autino et al., 1999, 2009). The known host records for Megistopoda aranea are mainly from bats of the family Phyllostomidae , as Artibeus fimbriatus , A. lituratus , A. planirostris (Spix, 1823) and Desmodus rotundus É. Geoffroy, 1810 ( García, 1959 ; Barquez et al., 1991; Autino et al., 1992, 1998, 1999, 2000b, 2009, 2018).
