Poneracantha lucaris

Quick Summary

• Difficulty: Hard
• Origin & Habitat: Southern Brazil, Atlantic Forest regions (Santa Catarina, São Paulo, Minas Gerais) ^[1][2]
• Colony Type: Unconfirmed colony structure, likely single-queen based on typical Poneracantha patterns
• Size & Growth:
  • Queen: size data unavailable
  • Worker: size data unavailable
  • Colony: Unknown, no colony size data available
  • Growth: Unknown
  • Development: Unknown, no development data available for this species (No direct measurements exist. Related species may take 2-4 months at tropical temperatures, but this is an estimate.)
• Antkeeping:
  • Temperature: Likely 22-28°C based on Brazilian tropical origin
  • Humidity: Likely prefers humid conditions typical of Atlantic Forest
  • Diapause: Unknown
  • Nesting: No specific nesting data. Recommend test tube setup initially, transitioning to plaster or naturalistic nests with moist substrate
• Behavior: Temperament unconfirmed, based on subfamily Ectatomminae, they possess a sting for defense. Escape risk is moderate, they can climb smooth surfaces, so standard barriers should suffice.
• Common Issues: limited species-specific husbandry data makes care recommendations uncertain., no documented captive breeding success to reference., predatory diet requirements may be challenging to meet consistently., wild-caught colonies may have parasites or fail to adapt to captivity., tropical humidity requirements may promote mold in captive setups.

Species Identification and Taxonomy

Poneracantha lucaris was originally described as Poneracantha lucaris and later transferred to Poneracantha ^[2]. It belongs to the lucaris complex in the ericae subgroup of the sulcata species group ^[2]. Key features include striate body sculpturing, a subquadrate head, smooth scapes, and denticulate mandibles ^[1][2]. The petiolar node has a convex dorsal margin, and the metacoxal dorsum has an acute tooth ^[1].

Distribution and Habitat

This species is known only from southern Brazil, specifically Atlantic Forest regions of Santa Catarina, São Paulo, and Minas Gerais ^[1][2]. The type locality is Santa Catarina, Ibirama, with paratypes from São Paulo and Minas Gerais ^[2]. The Atlantic Forest is a humid ecosystem, suggesting the species prefers shaded, moist forest floor environments.

Feeding and Diet

Poneracantha lucaris is predatory. One observation shows a worker devouring a beetle on a shrub ^[2]. In captivity, offer small live prey like fruit flies or pinhead crickets 2-3 times per week, removing uneaten items after 24 hours to prevent mold.

Nest Preferences and Housing

No specific nesting data exists. Based on genus patterns, they likely nest in soil or rotting wood. For captive care, start with a test tube setup and transition to plaster or naturalistic nests with moist substrate as the colony grows.

Temperature and Seasonal Care

As a tropical species, likely prefer temperatures of 22-28°C. Keep the nest in the mid-20s and avoid extremes below 18°C or above 30°C. Monitor colony activity for temperature adjustments.

Behavior and Temperament

Workers are active foragers that hunt small invertebrates. Based on subfamily Ectatomminae, they have a sting for defense. Escape risk is moderate due to their size and climbing ability.
