Sumampattus quinqueradiatus

S. quinqueradiatus is a medium-sized jumping spider. Females measure approximately 6.0 mm in total length, while males are slightly smaller at about 5.4 mm.^[3]

The species displays distinctive coloration patterns. Females have a dark brown cephalothorax with a blackish head region covered in reddish-brown hairs. The head features five characteristic white hair bands: one running longitudinally down the center, two on each side extending from the posterior lateral eyes, and one on each side visible in frontal view extending from between the anterior lateral and median eyes. The abdomen is brown with yellow markings forming an irregular median band bordered by brown and black hair patches.^[2]

Males are generally darker than females, with a very dark brown prosoma featuring reddish hairs on the head region. The thoracic region has two broad pale brown bands with white hairs. The abdomen follows the basic female pattern but is much darker, with brown patches instead of the yellow ones seen in females.^[3]

The legs are yellow with blackish rings and patches. In both sexes, the femur has a broad basal ring (incomplete on the dorsal side) and a complete apical ring, the patella has the distal half darkened, and the tibia has broad basal and apical rings.^[3]

Specimens collected in Iguazú National Park in Argentina were found during September and October in vegetation bordering paths in fairly open and sunny areas.^[3] Laboratory observations showed that females can produce multiple egg sacs, and the juveniles can be successfully reared to maturity.^[3]
