Genus Birdantis Stål, 1863 

Birdantis Stål, 1863: 581  (described, compared with Aphaena Guérin-Méneville, 1834  ; type species: Birdantis decens Stål, 1863  by subsequent designation in Distant 1906: 26).

Myrilla Distant, 1888  : 487 (described, compared with Polydictya Guérin-Méneville, 1844  ; type species: Myrilla obscura Distant, 1888  , by monotypy). syn. rev.

Remarks

Lallemand (1959) synonymized Myrilla  under Birdantis  and proposed a key to the species of Birdantis  . However, Fennah (1977) considered Myrilla  as a subgenus of Birdantis  , separating them on characters of the vertex, i.e., anterior margin of vertex straight, without deep transverse sulcus behind it in Myrilla  ; anterior margin of vertex concave, with a deep transverse sulcus behind it in Birdantis  s. str. It is therefore currently formally divided into two subgenera: Birdantis  (ten species and one subspecies) and Myrilla  (two species) ( Fennah 1977; Nagai & Porion 1996). The genus is externally close to the Oriental Polydictya Guérin-Méneville, 1844  and Gebenna Stål, 1863  , and the Australian Desudaboides Musgrave, 1927  ( Lallemand 1963; Nagai & Porion 1996; Constant 2010, 2011). Nagai & Porion (1996) followed the classification in Fennah (1977), but in my paper on the species of Birdantis  from Australia ( Constant 2011), IAbout I questioned the value of the subgenera as defined by Fennah (1977), because intermediate species exist, and followed the views of Lallemand (1959) but without formally reinstating the synonymy between Birdantis  and Myrilla  . Accordingly, three species remained without subgeneric affiliation ( Bourgoin 2018) within the last formally accepted classification of Fennah (1977).

The genus Birdantis  is currently placed in the Poiocerina Haupt, 1929 of the Poiocerini Haupt, 1929, in the subfamily Poiocerinae  Haupt, 1929 ( Lallemand 1963; Constant 2011; Bourgoin 2018). However, Urban & Cryan (2009) have shown, based on molecular data, that Fulgoridae  can be separated into two main clades, one grouping all New World taxa with strong support, the other containing all Old World taxa. Hence, as the type genus of the Poiocerinae  is the Neotropical genus Poiocera Laporte, 1832  , the suprageneric placement of Birdantis  needs to be reconsidered.

The classifications proposed by Metcalf (1947), Lallemand (1963) and Nagai & Porion (1996) were based on a very small number of characters of the head, especially the presence/absence and shape of the cephalic process. The genus Birdantis  is here transferred to the subfamily Aphaeninae  , following the conclusions of the DNA study by Urban & Cryan (2009), which place the genus close to Desudaba Walker, 1858  . However, the latter study did not contain any species of the genera Polydictya  , Gebenna  or Desudaboides  , which are putatively considered closely related to Birdantis  based on morphological characters. Hence, an accurate tribal placement requires a complete study of the suprageneric relations between the genera of Aphaeninae  with the inclusion of more Old World taxa in the molecular analysis and the integration of morphological data ( Urban & Cryan 2009).
