Macrostelini Kirkaldy 1906

Tribe Macrostelini Kirkaldy, 1906 Macrostelini Kirkaldy, 1906: 342. Balcluthini Baker, 1915: 50. Gnathodini Baker, 1915: 50. Coryphaeini Emeljanov, 1962: 395, unavailable due to homonymy of the type genus. Coryphaelini Nast, 1972: 490. Diagnosis Small to medium sized, slender, often stramineous, yellow, or greenish deltocephalines, usually with symmetrical dark markings, forewing with 2 anteapical cells, subgenital plate usually with membranous digitate apical lobe, male pygofer macrosetae sometimes plumose. Remarks The analyses of Cao et al. (2022) (Fig. 1; Supp. file 2) consistently supported the monophyly of this tribe, as delimited by Knight & Webb (1993) and Zahniser & Dietrich (2013) with three exceptions. Cortona Oman, 1938 grouped with Deltocephalini, corroborating the transfer of this genus to that tribe by Duan et al. (2017). Teyasteles Linnavuori, 1969 grouped with Paralimnini, which is consistent with its linear connective articulated to the aedeagus. Evinus grouped as sister to Drakensbergena in a larger clade comprising Drakensbergenini, Eupelicini and Stenometopiini. Thus, although these three genera resemble Macrostelini in having only two anteapical cells in the forewing, they share morphological synapomorphies with other tribes and are here excluded from Macrostelini. Distribution Cosmopolitan. Excluded genera Evinus Dlabola, 1977 (to Eupelicini, unplaced to subtribe); Teyasteles Linnavuori, 1969 (to Paralimnini: Paralimnina).
