size approx 4.5 to 5 mm; under loose bark on Fucschia tree
This is the third observation of this species (that I know of). See:

The distribution is widespread and the phenotype seems quite "stable".

This male spider (6-7mm) was attracted by a small white moth sitting on the same leaf:

A scrappy expanse of silky refuges and capture webs littered with body parts of previous victims. When preferred prey is entangled, the female spiders emerge from their 'nests' and overpower it by grabbing its extremities. In this case, a wasp https://www.inaturalist.org/observations/9319446.
Presumably they inject venom because after a minute or so the prey stops struggling. Then they snip it out of the web and carry it into one of several 'nests' or refuges.
Unwanted prey, often beetles (see https://www.inaturalist.org/observations/9319435 ) are also killed but sometimes left in the web, uneaten. Ants, in this case, Maranoplus ( https://www.inaturalist.org/observations/9319390 )scavenge around the periphery of the webs, feasting on unwanted beetles or other left-overs.
