Type genus: Euscyrtus Guérin-Méneville, 1844 .

Distribution: Tropical regions, except South America.

Diagnosis: Mainly found in shrubs and tall grasses, from small to medium size. Top of fastigium truncated in frontal and lateral views ( Fig. 5B ; Supporting Information, Fig. S1G ). TIII with six or more inner subapical spurs; claws inner margin serrulate ( Fig. 5C ; Supporting Information, Fig. S6 Gb), more or less as in Trigonidiinae (Trigonidiidae) . FWs present or absent, when present generally without stridulatory apparatus. Ovipositor generally downcurved in lateral view; apex of dorsal valves above ventral apex of ventral valves; apex not enlarged; lateral margins of apex smooth ( Fig. 5D ).

Included genera: Beybienkoana Gorochov, 1988 , Burrianus Chopard, 1962 , Euscyrtodes Gorochov, 1987 , Euscyrtus Guérin-Méneville, 1844 , Merrinella Otte & Alexander, 1983 , Patiscodes Gorochov, 1988 , Patiscus Stål, 1877 , Proturana Otte, 1987 , Tozeria Otte & Alexander, 1983 , Turana Otte & Alexander, 1983

Remarks: There have been no records of these crickets in South America until now. However, some representatives (not yet described) with all features of Euscyrtinae were observed in the MNHN collection registered from South America (LDC, pers. obs.).
