Paragryllodes nitidula ( Bolivar, 1912) n. comb.

( Figs 1A , 2 A-D, Table 1)

Seychellesia nitidula Bolivar, 1912: 286 — Gorochov 2006: 445.

Type locality. Seychelles, Silhouette , near Mare aux Cochons, over 1000 feet ( Bolivar (1912).

Type material. Lectotype female (designated by Gorochov 2006), Seychelles, Silhouette island [′Silhouette′, ′08, Seychelles Exp. 21′, ′′type′, ′Figured specimen′, ′Holotype′, ′Seychellia gen. n. nitidula sp. n. ′, ′ Seychelles, Percy Sladen Trust Expedition, 1913-170′, “ syntype] ( NHM).

Other material examined. Seychelles, Silhouette , Jardin Marron vers Mt Pot à eau, 550 m, vue de nuit, 1 female (2010SEYSH200), 5.x.2010, S. Hugel, MNHN-EO-ENSIF12094 .

Molecular sampling. LDG 375 in Warren et al. (2019).

Remarks. Seychellesia nitidula is only known by females, but both molecular data ( Chintauan-Marquier et al. 2013, 2016) and morphology (see below) indicate that Seychellesia nitidula belongs to Paragryllodes Karny, 1909 and is not related to the other species from the Seychelles described under the name Seychellesia (i.e. Seychellesia patellifera Bolivar, 1912 and Seychellesia longicercata Bolivar, 1912 ), for which we describe here the new genus Seselia Hugel & Desutter-Grandcolas , n. gen. S eychellesia nitidula shares the following characters with Paragryllodes : shiny cuticula; eyes strongly protruding; fastigium lower than head dorsum, and separated from it by a transverse furrow; median ocellus in frontal position, apical on fastigium; maxillary palpi moderately elongate, article 4 distinctively shorter that articles 3 and 5; pronotum sulcated; LL more or less perpendicular to DD; female copulatory papilla forming a sclerotized chamber ( Fig. 2D ).
