Note:  This genus placed in the subtribe Numatina by Emeljanov 1993.

Type species (in original combination):  Bostaera nasuta Ball, 1902


= Cochise Kirkaldy, 1907: 63 (type species Cochise apacheanus Kirkaldy 1907: 64); syn. by Muir 1913: 239.

Recognized species

There are three recognized species in this genus (Palearctic species status revised by Della Giustina 2019):

Bostaera balli Penner, 1952 – USA: Florida, Georgia, North Carolina
Bostaera bolivari (Melichar, 1901: 56) – Spain, Palestine, Portugal, Egypt, Israel, Canary Islands
= Delphacodes bolivari Melichar, 1901
= Tricranoneura bolivari (Melichar 1901), comb by Horváth, 1922: 129.
= Bostaera bolivari (Melichar 1901b), comb. by Muir 1925b: 279.
= Bostaera horvathi (Muir, 1934) synonym of Amblycotis horvathi (Muir, 1934) by Fennah (1961): 309
= Amblycotis horvathi (Muir, 1934) synonym of Bostaera bolivari (Melichar, 1901) by Della Giustina (2019): 205
= Bostaera frontalis Lindberg, 1958 synonym by Della Giustina (2019: 215).
= Bostaera gomerense Carl, 1995 synonym by Della Giustina (2019: 215). (Canary Islands)
Bostaera nasuta Ball, 1902: 266 – USA: Arizona, California, Colorado, Florida, Georgia, Kansas, North Carolina, New Mexico, Texas; Mexico (Federal District, Quintana Roo:; Honduras   (Eastern records of this species should be checked – FL, GA, NC records are probably in error).
= Cochise apache Muir, 1913: 239 (lapsus for apacheanus Kirkaldy, 1907).
= Cochise apacheanus Kirkaldy, 1907: 64; syn. by Van Duzee, 1914: 164.

Plant associations

None reported, but in Norch Carolina (Bladen County), B. balli was taken on an unidentified grass.

This one (I know if can’t be identified from this, probably, but it is a start):Grass from Bladen Co., North Carolina on which Bostaera was found

Agonatopoides synchromus Perkins 1907 (Dryinidae, Hymenoptera) on Bostaera nasuta; see by Krombein 1979: 1245).

Economic Importance



The genus is distinctive and can be recognized among New World genera by the head broader than the pronotum, strongly flattened antennae, the frons widest near the top with the median carina forked low on the face.  The only North American genus that is somewhat similar is Stobaera, which shares flattened antennae and patterned wings. Also somewhat similar is the South American genus Neoperkinsiella.  The species are very similar externally, and differ only in that B. balli has fewer teeth on the aedeagus with the proximal teeth much larger than the distal.  Members of this genus are very similar to the genus Pseudaraeopus Kirkaldy, 1904.  The species of Pseudaraeopus initially described in Bostaera (viz. P. frontalis (Lindberg, 1958)) and one member of Amblycotis (viz. A. horvathi (Muir, 1934)) are now synonyms of Bostaera bolivari (see Della Giustina 2019).
