Abstract.— Huntiglennia williamsi gen. and sp. nov. is described from New South Wales, Australia. Remarks on relationships and biology are provided and diagnostic drawings and distributional map is given.

 Key words.— Salticidae, Australia, new genus, new species.

The material was provided by Graham Milledge In cases such as Huntiglennia, Athamas and other genera (Australian Museum, Sydney = AMS). The details of from various subfamilies, eye arrangement seems to have specimen examination were described earlier (Żabka nothing to do with salticid origin as other characteristics, 1991). The following measurements were taken: including genitalia, are typical for higher salticids.
