(2014) list the holotype as SMF 9338 2a (Sydney, NSW, collected W. Kirschner or A.

Comment	Venomous! Synonymy partly after COGGER 1983. Habitat: may be partially marine, occuring in marshes along the east coast of Australia. Type species: Alecto signata JAN 1859: 128 is the type species of the genus Hemiaspis FITZINGER 1861. Diagnosis (genus): Cogger 1986 ? (fide Hutchinson 1990, who doesn’t cite Cogger 1986).
Etymology	Presumably named after the Latin signatus (marked) in reference to the pale labial and temporal stripes. (G. Shea, pers. comm., 9 Feb 2024)
