Abstract: Genus Shelfordina Diagnosis Both sexes fully winged (Figs 1A, B; 5A–C; 7A); hind wings often not reaching end of abdomen. Discoidal sectors of tegmina, longitudinal or sublongitudinal. Hind wing with some coastal veins “clubbed” or thickened (Figs 2E; 3A; 4A; 7H), discoidal vein straight, simple; median vein straight and simple, rarely with a small apical branch; cubitus vein usually straight, rarely weakly concave, with 0 to 5 complete branches, incomplete rami nearly always absent, apical triangle present except in species with reduced wings. Fore femur either type A 2 or A 3, (Figs 1D; 7C) if the latter then first terminal spine only slightly longer than the preceding one. Pulvilli present on 4 proximal tarsomeres; tarsal claws symmetrical, specialised in that the ventral margins are serrated, arolia present. Male abdominal tergites unspecialised, except in 2 species the eighth segment is enlarged and bears sparse setae; exposed portion of subgenital plate symmetrical; styles widely separated, usually with a style-like structure (Accessory Style) arising near their bases, presenting the appearance of 4 styles (Figs 3E; 4C, F, G; 5D; 7D). Supraanal plate transverse, symmetrical, right and left paraprocts similar, without spine-like processes. Genital hook on the right side. Females, like others in the subfamily, do not rotate the ootheca on oviposition. Instead, they carry it in the vertical position as indicated by collected specimens bearing oothecae.
