TRIBE APHONOMORPHINI DESUTTER, 1988

Aphonomorphini Desutter, 1988: 362, Otte, 1994: 78, Gorochov, 1995: 29.

Type genus: Aphonomorphus Rehn, 1903 .

Distribution: Neotropics.

Diagnosis: Medium to large-sized; FWs and HWs developed, surpassing abdomen, FWs without stridulatory apparatus, shorter than HWs (Fig. 12A). Posterior margin of eyes slightly concave (Fig. 12B; Supporting Information, Fig. S1 Ea); PCu vein not curved, sometimes with stridulatory teeth on ventral face; TI inner tympana present (except Paraphonus), frequently profound; Apical spurs of tarsomere I of leg III same-size or longer than tarsomere I (Fig. 12C, D). Male genitalia: elongated, sometimes asymmetric (Fig. 12E); EctAp elongated; ectophallic arc straight; EndAp well developed, flattened laterally (Fig. 12E; Supporting Information, Fig. S9A).

Included genera: Aenigmaphonus Gorochov, 2010, Aphonomorphus Rehn, 1903, Eneopteroides Chopard, 1956, Podoscirtodes Chopard, 1956 (transferred from Podoscirtinae), Paraphonus Hebard, 1928, Spiraphonus Gorochov, 2010 .

Remarks: Aphonomorphini do not have a stridulatory apparatus. However, several representatives of this group, like Aphonomorphus and Eneopteroides, have stridulatory teeth in the ventral face of the PCu vein, which is not curved. These crickets also have tympana on TI, indicating that they could emit acoustic signals or avoid predators. There are no records of acoustic communication within this tribe. The genus Podoscirtodes was included in the Podoscirtinae subfamily (Cigliano et al., 2022), but it does not belong to any group inside this subfamily. The characteristics mentioned in the diagnosis above fit the characteristics of this genus, allowing its transfer to Aphonomorphini . Furthermore, the records of Podoscirtodes are all from Neotropical region (Cigliano et al., 2022), which match the distribution of the Aphonomorphini tribe.
