Shoulder-knob Bark Spider

Amazing spider. I found them on tree with very dark red and resin covered bark in open parkland. There were deep grooves in the bark. Somehow I managed to spot two individuals in close proximity of each other, a large one maybe around 14mm and a much smaller one around 10mm. They were facing each other. I assume the small one was a male, the larger one a female. The male was in crouching position, legs like masts sticking into the air. The female was more open but still difficult to see inside a groove. At the very end it did do me the favor and it moved only to hide in an even deeper groove. The female's body seemed covered in fresh and shiny resin. The body was heavily pustulose, also much wider than the male. I identified this specimen based on http://arachne.org.au/01_cms/details.asp?ID=2061 , an informal identification that can not be found on ALA nor GBIF, but is commonly used on the web. Lacking an English name from the reference site, I gave it my own name. Of course, I'll change it as soon as it is officially named. Frankly, I would have preferred to call it resin spider, but tried to follow the characteristic feature described. Update 2/7/2017: Last week, I found two spiders that look similar to the ones previously found. They were on the same tree trunk, again near resin, but not covered with it this time. Their eyes were shiny green dots on a head bump. End of abdomen is heavily knobbed. It could be a different species but I might keep them in one gallery for now.
