TYPE GENUS: Axonya Andrewes, 1923.

DIAGNOSIS: Mentum tooth simple, glossal sclerite with two setae, basal orifice of median lobe dorsally open, right and left parameres setiferous, sclerite X of internal sac thin, without upturned projections.

INCLUDED TAXA: This new subtribe is proposed for the first clade of Broscini that includes three genera: Axonya, Broscodes, and Rawlinsius. In contrast with to relatively closely related groups of Broscina genera, the members of Axonyina are definitely more remote, and cannot be placed in the subtribe Broscina. No character is exclusive from this subtribe and the characters that define Axonyina are: subocular zone narrow (51), basal stipes with three setae (182), anterior border of prosternum with edge (261), male with foretarsomeres 1–3 with adhesive vestiture (441), left paramere enlarged (533), and median lobe with basal expansions (561). On the basis of the median lobe and sclerites of internal sac, Axonyina appears to be the most primitive member of Broscini.

The three genera of Axonyina are monospecific with restricted distribution and occur in different regions. Axonya is Oriental, Broscodes is Palaearctic, and Rawlinsius occurs in the northern part of Neotropical region.
