Group B is also taxonomically polyphyletic (Fig. 1). Sister to the rest of the group (subgroup B1) are “Hylocharis” leucotis (Vieillot) and “H.” xantusii (Lawrence). However, the phylogeny (McGuire et al. 2014) separates the rest of Hylocharis Boie, 1831 including its type species sapphirina (Gmelin,1788) in group D (see below). Ridgway (1911) and Cory (1918) treated leucotis and xantusii in the genus Basilinna Boie, 1831, but Peters (1945) merged it into Hylocharis without comment. More recently, Howell & Webb (1995), Schuchmann (1999) and Hernández et al. (2014) have provided evidence that Basilinna should be restored for leucotis (Vieillot, 1818), its type species, and xantusii, which is supported by the genetic data. Here again, the character used by many authors to diagnose Hylocharis, the expanded red base of the bill in adult males, shows considerable homoplasy and is of little phylogenetic value.
