The Phalangopsidae crickets (Grylloidea) of the Seychelles are examined following extensive field sampling on several main islands of the archipelago (Mah, Silhouette, Praslin, La Digue). Despite the small area of these islands, six genera (12 species) are documented, including one new genus and five new species. The type species of the genus Seychellesia Bolivar, 1912 is transferred to the genus Paragryllodes Karny, 1909 as Paragryllodes nitidula (Bolivar, 1912) n. comb. The other species described in Seychellesia are transferred to the genus Seselia Hugel Desutter-Grandcolas, n. gen., as Seselia longicercata (Bolivar, 1912) n. comb. and Seselia patellifera (Bolivar, 1912) n. comb. Two new species are also described in the genus Seselia Hugel Desutter-Grandcolas, n. gen., Seselia coccofessei Hugel Desutter-Grandcolas, n. gen., n. sp. (type species of the genus) and Seselia matyoti Hugel Desutter-Grandcolas, n. gen., n. sp. The genera Phaeogryllus Bolivar, 1912 and Phalangacris Bolivar, 1895 are redescribed, including Phalangacris ferlegro Hugel Desutter-Grandcolas, n. sp. and Phalangacris sotsote Hugel Desutter-Grandcolas, n. sp. that are new to science. The genus Gryllapterus Bolivar, 1912 is redescribed and transferred from the Landrevinae (Gryllidae) to the Cachoplistinae (Phalangopsidae). New tribes are defined for the genus Paragryllodes (Paragryllodini Hugel Desutter-Grandcolas, n. tribe) on the one hand, and for Seselia Hugel Desutter-Grandcolas, n. gen., Phalangacris, Phaeogryllus and Gryllapterus (Seselini Hugel Desutter-Grandcolas, n. tribe) on the other, using morphological characters and the results of molecular phylogenetic studies (Warren et al. 2019). Phaloria (Papuloria) insularis (Bolivar, 1912) (Phaloriinae) is redescribed and restricted to Mah, and its calling song is documented for the first time, while Phaloria (Papuloria) bolivari Hugel Desutter-Grandcolas, n. sp. is newly described from Silhouette. Identification keys are proposed for the genera of Seselini Hugel Desutter-Grandcolas, n. tribe, and for the species of Seselia Hugel Desutter-Grandcolas, n. gen. and Phalangacris. The confusion between the Mogoplistidae Ornebius succineus Bolivar, 1912 and the Phalangopsidae Heterotrypus succineus Bolivar, 1910 is discussed, and the name Subtiloria succineus (Bolivar, 1912) considered a nomen nudum.
塞舌尔群岛的 Phalangopsidae 蟋蟀（直翅目）在对群岛的几个主要岛屿（Mah、Silhouette、Praslin、La Digue）进行广泛的实地采样后进行了检查。尽管这些岛屿的面积很小，但记录了六个属（12 种），包括一个新属和五个新种。Bolivar 于 1912 年创立的 Seychellesia 属的模式种被转移到 Paragryllodes Karny，1909 属，作为 Paragryllodes nitidula（Bolivar，1912）n.comb。在 Seychellesia 中描述的其他物种也被转移到 Seselia Hugel Desutter-Grandcolas，n.gen.，作为 Seselia longicercata（Bolivar，1912）n.comb.和 Seselia patellifera（Bolivar，1912）n.comb。Seselia Hugel Desutter-Grandcolas，n.gen.也描述了两个新种，Seselia coccofessei Hugel Desutter-Grandcolas，n.gen.，n.sp.（属的模式种）和 Seselia matyoti Hugel Desutter-Grandcolas，n.gen.，n.sp.。Phaeogryllus Bolivar，1912 和 Phalangacris Bolivar，1895 属也被重新描述，包括 Phalangacris ferlegro Hugel Desutter-Grandcolas，n.sp.和 Phalangacris sotsote Hugel Desutter-Grandcolas，n.sp.，这是新的科学。Gryllapterus Bolivar，1912 属从 Landrevinae（Gryllidae）转移到 Cachoplistinae（Phalangopsidae）并重新描述。Paragryllodes（Paragryllodini Hugel Desutter-Grandcolas，n.tribe）属和 Seselia Hugel Desutter-Grandcolas，n.gen.，Phalangacris，Phaeogryllus 和 Gryllapterus（Seselini Hugel Desutter-Grandcolas，n.tribe）属使用形态特征和分子系统发育研究的结果（Warren 等人，2019 年）定义了新的部落。Phaloria（Papuloria）insularis（Bolivar，1912）（Phaloriinae）被重新描述并仅限于 Mah，并记录了它的叫声，而 Phaloria（Papuloria）bolivari Hugel Desutter-Grandcolas，n.sp.则是从 Silhouette 新描述的。提出了 Seselini Hugel Desutter-Grandcolas，n.tribe 属、Seselia Hugel Desutter-Grandcolas，n.gen.和 Phalangacris 种的鉴定钥匙。讨论了 Mogoplistidae Ornebius succineus Bolivar，1912 和 Phalangopsidae Heterotrypus succineus Bolivar，1910 之间的混淆，并认为 Subtiloria succineus（Bolivar，1912）是一个无效名。
