Agraecia Serville, 1825

Agraecia differens Redtenbacher, 1891 is misplaced in this genus and is hereby transferred to Secsiva Walker 1868 . The type species of Agraecia Serville 1825 is Locusta punctata Saint-Fargeau & Serville , by original monotypy (Otte & Eades, 2009) which is from northeastern Bahia, Brazil. The type locality of A. differens is Cape York, Queensland, Australia. This species is easily referable to Secsiva Walker 1868 , the type species of which is Secsiva univitta Walker by original monotypy (http://osf2x.orthoptera.org/Common/basic/Taxa.aspx?TaxonNameID=2292). It was described from Victoria River, Northern Territory. I am aware of about a dozen Australian undescribed species that can be placed in Secsiva . They all occur in the northern, tropical region of Australia. None of the other Agraecia species occurs in Australia.

Secsiva is characterized by its overall light brown appearance with frons, genae and tegmina often with thin, bluish green markings. Both sexes have species-distinctive male and female genitalia. The ovipositor is either elongate or sickle-shaped depending upon the species. There seems to be two body plans within Secsiva . There are elongate species, as with S. univittata , and more robust forms as illustrated by S. differens .
