SUPERTRIBE DIATRYPIDI DESUTTER, 1988 SUPERTRIB. NOV.

Diatrypini Desutter, 1987: 235, Desutter, 1988: 369, Otte, 1994: 65, Gorochov, 1995: 1–213.

Diatrypina Gorochov, 2013: 16, Gorochov, 2017: 98.

Type genus: Diatrypa Saussure, 1874 .

Distribution: Neotropics.

Diagnosis: Small-sized with developed HWs, FWs, and stridulatory apparatus ( Fig. 8A, B ). FWs apical field present, generally smaller or with same size of mirror; TI auditory tympana present on inner and outer faces; TIII subapical spurs 5/5. Female subgenital plate posterior border surrounding ovipositor (Supporting Information, Fig. S4J ). Ventral valves of ovipositor bifurcate; apex of ovipositor wider than the structure in dorsal and ventral views (Supporting Information, Figs S4J, S 5C, D ). Male genitalia: dorsal valves well-developed; endophallic sclerite elongate, two or more times longer than pseudepiphallic sclerite (Supporting Information, Fig. S7D ); spermatophore generally well developed and well sclerotized.

Included genus: Diatrypa Saussure, 1874

Remarks: Previously considered a subtribe of Aphonoidini (Podoscirtinae) ( Cigliano et al., 2022), this lineage is elevated to supertribe and is transferred to Oecanthinae based on the phylogenetic hypotheses presented here. This clade includes only one genus divided into two subgenera with 67 species. The genus Diatrypa must be reviewed, as many new taxa (specimens observed in MNHN and MZSP) are to be described. This group is presently poorly documented, perhaps because it occurs mostly in the canopy.
