Trapezoid crab spider

Sidymella trapezia is a pale coloured spider with a trapezium shaped abdomen. Darker markings follow the line of the body within the margins.

I think this is a female going by the pedipalps, but much smaller than the 7 mm average - it was tiny, nearer 3 mm body length, so perhaps a juvenile.

N.B. Not captive - this tiny spider fell/made for safety on to the potting gravel as I was dead-heading the flowers of the plant.
