A pale, semi-transparent spider usually found on foliage, with a trapezium shaped abdomen. Darker markings follow the line of the body within the margins. Widespread and common across Australia from west to east including islands. Females to 7mm, males to 4mm. Smaller than Sidymella longipes and with more equally sized legs. Originally placed in Stephanopis by Koch in 1874, then into Sidyma by Simon in 1908, but that generic name was preoccupied and the name Sidymella was erected in 1942 by Strand.
