Subtribe Heterogryllina Saussure, 1874

Type genus. Heterogryllus Saussure, 1874

Remarks. Saussure (1874) defined the genus Heterogryllus for one female originating from Brazil, described as Heterogryllus ocellaris . Two other species have been described in the genus, Heterogryllus crassicornis Saussure, 1878 and Heterogryllus bordoni Chopard, 1970 , transferred to Aclodes Hebard, 1928 and Paraclodes Desutter- Grandcolas, 1992 respectively (see Desutter-Grandcolas 1992b, 2014). In molecular-based phylogenetic analyses ( Chintauan-Marquier et al. 2013, 2016; Warren et al. 2019), Aclodes and Paraclodes constitute a well-separate clade within the Paragryllinae (not the Phalangopsinae ), defined elsewhere as the tribe Aclodini Desutter-Grandcolas, 2020 ( Desutter-Grandcolas & Faberon 2020). Heterogryllus is presently included in the subtribe Heterogryllina of the subfamily Phalangopsinae ( Cigliano et al. 2021) .

Hebard (1928a) reconsidered the cricket genera gathered by Saussure (1878) in the «Légion Phalangopsites» (= Bruner’s 1916 Phalangopsitidae) and distributed their Neotropical representatives into two assemblages, which he named the group Luzarae ( Hebard 1928a) and the group Heterogrylli ( Hebard 1928b). While the Luzarae are clearly defined by Hebard in his first 1928 paper ( Hebard 1928a: 2), the Heterogrylli are not. Hebard (1928b) just listed some genera in this group, i.e. Eugryllina Hebard, 1928b (now a Strogulomorphina, see Desutter-Grandcolas 1991), Acla Hebard, 1928b (synonymized with Aclodes by Desutter-Grandcolas 2014), Aclodes Hebard, 1928b , and Ectecous Saussure, 1878 , with short comments on the descriptions of the new taxa.

Gorochov (2014) used the subtribe Heterogryllina Hebard, 1928 within his Phalangopsinae subfamily, for Uvaroviella Chopard, 1923 (subdivided into nine subgenera) and possibly Heterogryllus , to which Gorochov (2015) added six genera, i.e. Phalangacris Bolivar, 1895 and Seychellesia Bolivar, 1912 from the Seychelles, Phaeophilacris Walker, 1871 from Africa, Aspidogryllus Chopard, 1933 from India, Howeta Otte and Rentz, 1985 from Lord Howe island and Hemicophus Saussure, 1878 from the Neotropics.

Molecular phylogenetic evidence ( Chintauan-Marquier et al. 2013, 2016; Warren et al. 2019) clearly showed that Heterogryllina sensu Gorochov is a polyphyletic assemblage. Phaeophilacris , which constitutes a monophyletic clade, has anyway been accommodated in a different subtribe of the Heterogryllini, the Phaeophilacridina ( Gorochov 2020) . Following Chintauan-Marquier et al. (2013, 2016), Uvaroviella and its nine subgenera have been reviewed and transferred to the tribe Aclodini of the Paragryllinae subfamily ( Desutter-Grandcolas & Faberon 2020). Here we remove Phalangacris Bolivar, 1912 and Phaeogryllus Bolivar, 1912 from the phalangopsine Heterogryllina to transfer them in the Seselini Hugel & Desutter-Grandcolas , n. tribe of the Cachoplistinae subfamily (see below).
