Remarks. Only three species of Arasia   are known: A. mollicoma (Koch)   , A. eucalypti Gardzińska   and the present species, all of them are tree-trunk dwellers in open sclerophyll forests. Arasia aurea (Koch)   listed by Wanless (1988) is excluded from Adoxotoma   and transferred to the genus Sondra   (see below).
