Lithilaria proestans.

When Moths of Victoria Volume 2 first edition was published in 2009 there were just four Victorian records of this moth in the Herminiidae family, and all four were from Noorinbee in the far east of the state. Then, in 2011, a male came to the light in November, at Maffra, two hundred kilometres to the west. The habitat consists of a native garden in dry grazing country. The male moth is characterised by the pectinate antennae, and the long palpi that curve back over the head and in the pictured individual reach to the end of the thorax.

Twelve months later, male and female moths came to the light at the same location.

The palpi of the female are also large, but less so than those of the male.

A close view of the palpi.

Another male record was made at the end of October 2015, in the foothills below Mount Moornapa, moist tall forest. The palpi of this individual do not seem to be quite as long as the first pictured, although that may  just be due to the attitude of the moth and the camera angle.
