Is a medium-sized orb-weaver spider belonging to the Araneidae family, characterized by a pronounced sexual dimorphism where adult females reach a body length of 6 to 10 mm, while males are considerably smaller, ranging between 4 and 6 mm. The carapace is brownish and covered with fine, pale pubescence. Its globose, slightly oval abdomen (opisthosoma) displays a complex dorsal pattern known as a folium, which resembles a scalloped leaf with varying shades of brown, gray, and yellow, bordered by lighter bands. The legs are robust, armed with numerous macrosetae (spines), and feature alternating dark and light rings that provide excellent camouflage against bark and twigs in shrubby vegetation.

Geographical distribution: This species is native to the southern temperate and subtropical regions of South America. Its documented range spans across Argentina (with prominent records in the provinces of Buenos Aires, Entre Ríos, and Santa Fe), Uruguay, and the southern and southeastern states of Brazil, establishing itself along major river basins and coastal plains.

Habitat: Prefers a diverse array of terrestrial environments, particularly gallery forests, riparian woodlands, shrubby steppes, and humid thickets. It is highly adaptable to anthropogenic environments, frequently colonizing suburban gardens, public parks, orchards, and agricultural edges where woody vegetation provides stable anchor points for web construction.

Feeding: It is a generalist insectivore that relies on its vertical orb web to capture flying insects. The diet primarily consists of dipterans, hymenopterans, microlepidopterans, and small coleopterans. Upon detecting high-frequency vibrations from an entangled prey, the spider moves swiftly to wrap the insect in silk, delivering a paralyzing venomous bite before digesting the internal tissues extra-orally.

Behavior: Exhibits mostly crepuscular and nocturnal activity. During the night, it constructs or reconstructs its geometric, sticky orb web. Throughout the daylight hours, it either sits motionless at the hub of the web or retreats into a silken dome-like shelter constructed from curled leaves near the web´s margin, remaining connected to the center via a signal thread that transmits vibrational cues.

Reproduction: Mating takes place during the warmer months of spring and summer. The male must perform a delicate and hazardous courtship ritual, vibrating the female´s web threads in a specific pattern to signal his identity and prevent a predatory response. Following successful copulation, the female deposits her eggs in a dense, fluffy egg sac made of yellowish-brown silk, hiding it under foliage or crevices in the bark. The spiderlings hatch after a few weeks, remaining in a communal cluster before dispersing via ballooning on wind currents.

Conservation status: This species has not been evaluated (NE) by the International Union for Conservation of Nature (IUCN). It is considered locally abundant across its distribution range, face no immediate ecological threats, and adapts well to mild habitat modifications.
