Stephanotheisa Soyka 1931: 111 ; Nowicki, 1935: 572 (synonymized). Type species: Stephanotheisa vitoldi Soyka , by monotypy. Grantranna Girault 1939: 324; replacement name for Neocentrobia Blood 1923: 254 ; nec Girault 1912: 91–92.

Diagnosis. Marked sexual dimorphism in the antennae: female antenna 9-segmented with two anelli, two funicle segments obliquely divided and the junction is confused, club 3-segmented; male antenna 10-segmented with a 4-segmented club with whorls of curved bristles, the terminal segment very small, bud-like. Maxillary palp 1-segmented. Fore wing very broad, oblate and nearly truncate apically, stigmal vein as long as marginal vein, setal tracks very distinct. Male genitalia with aedeagus fused to genital capsule.

Hosts. Primarily Cicadellidae ( Lin, 1994; Owen, 2011). Other records are from Miridae ( Viggiani, 1988) and Tettigoniidae ( Timberlake, 1927) ; but those from Pyralidae ( Peck, 1963) need verification and are probably incorrect ( Owen, 2011).

Distribution. Worldwide, though apparently uncommon in South America ( Owen, 2011).
