In 1966 1 described a new species of the extinct order Protelytrop- 
tera belonging to a new genus, Stenelytron, and representing a new 
family, Stenelytridae. Having recently learned from Professor F. M. 
Carpenter that the name Stenelytron is preoccupied, I am herein 
proposing a replacement name, as follows: 
Labidelytron, nomen novum pro Stenelytron Kukalova, 1966, p. 
102, non Handlirsch, 1906, p. 451. The type species, Stenelytron 
enervatum Kukalova, 1966, original designation, becomes Labidely- 
tron enervatum (Kukalova), new combination. The genus is known 
only from the Permian of New South Wales, Australia. 
The family name, Stenelytridae Kukalova, 1966, p. 102, is herein 
replaced by Labidelytridae. The genus Xenelytron (Kukalova), 
1966, p. 105, also from the Permian of New South Wales, is the only 
other genus known in the family.
