SUBFAMILY TAFALISCINAE DESUTTER, 1988, DEFIN NOV.

Tafaliscinae Desutter, 1988: 367 .

Tafaliscini Desutter, 1988: 367, Otte, 1994: 68, Gorochov, 1995: 1–213.

Tafaliscina Gorochov, 2011: 254, Gorochov, 2017: 87, Campos, Souza-Dias & Nihei, 2020: 333, Campos & Desutter-Grandcolas, 2020: 393.

Type genus: Tafalisca Walker, 1869 .

Distribution: Neotropics.

Diagnosis: Small to large-sized, FWs absent, brachypterous or well-developed wings (with or without stridulatory apparatus) (Figs 17A, 18A, 19A; Supporting Information, Fig. S2A–C). Fifth and fourth articles of maxillary palpi with similar size, fifth article slightly upcurved (Fig. 16A); when FWs with stridulatory apparatus present; stridulatory file sinuous or bisinuous ( Paroecanthini): proximal connection of harp veins generally present. FIII generally longer than TIII; TIII subapical spurs 5/4 (Supporting Information, Fig. S6B) (except some Paroecanthini 5/5 and Perutrella 4/3). Ovipositor flattened dorso-ventrally, upcurved in lateral view; apex of dorsal valves above ventral valves (Fig. 16B); apex lateral margins of ventral valves of ovipositor smooth (Fig. 16 Cb). Male genitalia: inner margin of LLophi frequently membranous (Supporting Information, Fig. S7A, C).

Included supertribes: Paroecanthidi Gorochov, 1986, supertrib.nov., Tafaliscidi Desutter, 1988, supertrib. nov.

Remarks: After its proposal (Desutter, 1988), this subfamily was considered as a tribe (Gorochov, 1995) and later as a subtribe (Gorochov, 2011) within the Podoscirtinae subfamily. The results presented here, including the topologies and their synapomorphies, support the hypothesis that this Neotropical lineage is a subfamily of Oecanthidae composed of two supertribes ( Paroecanthidi and Tafaliscidi) redefined below.
