SUPERTRIBE PODOSCIRTIDI SAUSSURE, 1878 SUPERTRIB. NOV.

Podoscirtites Saussure, 1878: 693. Saussure, 1893: 257.

Type genus: Podoscirtus Serville, 1838 . Distribution: Afrotropics, Australasia, Indo-Malaya, Oceania and Palaearctic.

Diagnosis: FWs and HWs well developed, frequently covering the entire abdomen, generally with stridulatory apparatus developed ( Fig. 10A ), sometimes with FWs bearing only longitudinal veins ( Fig. 10B ). When stridulatory apparatus developed, stridulatory vein (PCu) curved, forming a 90° angle, proximal branch parallel to CuPa ( Fig. 10C ); CuPa higher than CuPb in lateral view.TI inner tympanum, when present, generally profound. Male genitalia: MedLophi of pseudepiphallic sclerite when present, short; MedLophi dorsal to LLophi ( Fig. 10D ; Supporting Information, Fig. S8E ).

Included tribes: Aphonoidini Gorochov, 1986, Podoscirtini Saussure, 1878, Truljaliini Gorochov, 2020 defin. nov.

Remarks: The clade corresponding in our phylogeny to the Podoscirtidi is clearly undersampled. Future phylogenetic studies on this supertribe, including more taxa, will be necessary to organize and verify more tribes as proposed herein. Besides, ProzƲenella bangaloriensis appears isolated in the ML (Supporting Information, Fig. S13 ) and MP (Supporting Information, Fig. S14 ) trees. In BI this taxon resolves inside Podoscirtini ( Fig. 3 ). Thus, we decided to maintain this genus as classified in Cigliano et al. (2022). For these reasons, we avoid designing subtribes, as the relations between, and definitions of, present-day genus groups are still unclear.

Red numbers are the mean ages of the nodes. Bars indicate 95% highest posterior density intervals for nodes of interest. Posterior probabilities different from 1 are indicated in black numbers on nodes. Inset A, lineages-through-time plot.
