Cyclosa hamulata

Female C. hamulata have a body length ranging from 6.73 to 11.44 mm.^[2]

The carapace is dark brown, while the abdomen shows variation in coloration, appearing either black with one or two pairs of silver spots, or silvery brown with dark markings and sometimes silver spots. The abdomen is slender with a caudally bifurcated end and features a pair of lateral humps positioned about one-quarter to one-third from the caudal end.^[2]

Males are considerably smaller than females, with a body length of 4.08–4.85 mm.^[2]

The male carapace is dark brown, and the abdomen is typically black, sometimes featuring two pairs of silver spots. A distinctive feature of males is the hook-shaped distal part of the median apophysis of the palp, which is the source of the species' name.^[2]

The specific name "hamulata" refers to the hook-shaped (Latin: hamulus, meaning small hook) distal part of the median apophysis found in the male palp.^[2]
