Tribe Seselini Hugel & Desutter-Grandcolas , n. tribe

Type genus. Seselia Hugel & Desutter-Grandcolas , n. gen.

Included genera. Seselia Hugel & Desutter-Grandcolas , n. gen., Phalangacris Bolivar, 1912 , Phaeogryllus Bolivar, 1912 , Gryllapterus Bolivar, 1912 .

Distribution. The granitic Seychelles Archipelago.

Diagnosis. Large to very large species with elongate legs (except Gryllapterus ). Coloration clear and contrasted (except Phaeogryllus , entirely dull brown); cuticula not shiny. Head not very long for Phalangopsidae crickets. TI with two apical, ventral spurs; with inner tympanum, outer tympanum lacking (present in Phaeogryllus ). TII with three ( Seselia Hugel & Desutter-Grandcolas , n. gen., Gryllapterus ) or four ( Phaeogryllus , Phalangacris ) apical spurs. TIII with three inner and three outer apical spurs; 4/4 subapical spurs; serrulated between and above subapical spurs.

Male. FWs very short, not or only slightly overlapping; main veins longitudinal. Stridulatory structures lacking, even the file. Wings lacking. FWs without glandular structures (except in Phalangacris ). Tergites not glandular, except in Seselia Hugel & Desutter-Grandcolas , n. gen. and Gryllapterus , where both meso and metanotum present glandular pits and areas with long setae. Male genitalia: pseudepiphallic sclerite flat, wider than long, more or less triangular; two short apical median lophi, separated by a V- or U-shaped emargination, with slightly raised apex bearing short setae; an additional sclerite on each latero-ventral side of pseudepiphallic sclerite, developed as ventral hooks in Gryllapterus (pseudepiphallic lateral lophi?). Pseudepiphallic parameres made of two well-separated sclerites, a dorsal (close to pseudepiphallic sclerite) one, simpler, and a ventral one, larger and subdivided into an inner (smaller) and an outer (bigger) parts. Ectophallic arc complete or nearly so, located in a very anterior location between the apex of ectophallic apodemes and the pseudepiphallic parameres: ectophallic sclerotization thus having the shape of an elongate H. No ectophallic dorsal valves. Endophallic sclerite located posteriorly to the arc. No endophallic cavity.

Female. Ovipositor apex neither widened, nor ornamented. Female genitalia: copulatory papilla not forming a closed chamber.
