Pheidole subaberrans

Quick Summary

• Difficulty: Hard
• Origin & Habitat: Endemic to the Yungas cloud forests of northwestern Argentina (Tucumán and Salta provinces), found at elevations from 300-1200m in premontane and basal forest zones ^[1][2].
• Colony Type: Colony structure is unconfirmed, Pheidole species are typically monogyne (single queen) but this has not been documented for subaberrans specifically.
• Size & Growth:
  • Queen: Size data unavailable
  • Worker: Size data unavailable
  • Colony: Unknown, typical Pheidole colonies can reach up to thousands of workers over time
  • Growth: Unknown
  • Development: Based on genus patterns, may take 6-10 weeks at warm temperatures (No species-specific data available, estimates based on Pheidole genus patterns)
• Antkeeping:
  • Temperature: Based on Yungas habitat, aim for moderate temperatures around 20-24°C, with a gradient if possible ^[1][2].
  • Humidity: Provide a humidity gradient, mostly dry nest chamber with one small moist area, based on montane cloud forest habitat ^[1][2].
  • Diapause: Unknown, based on subtropical latitude, diapause may not be required, but unstudied.
  • Nesting: No specific data, use standard Myrmicinae setups like test tubes for founding and Y-tong or plaster nests for established colonies.
• Behavior: Pheidole species are generally non-aggressive, with majors serving as defensive soldiers. Based on genus patterns, escape risk is moderate for minors and low for majors. Standard escape prevention with Fluon or tight lids is recommended.
• Common Issues: no established care protocols exist for this species, wild-caught colonies may harbor unknown parasites or diseases, care must be adjusted based on colony response due to lack of species-specific data, test tube setups must be monitored to prevent flooding, which can kill colonies

Species Discovery and Nomenclature

Pheidole subaberrans was first described by Kusnezov in 1952 from Argentina. The species name 'subaberrans' means 'almost aberrans', referring to its similarity to the related species Pheidole aberrans. It was originally placed in the subgenus Elasmopheidole, though modern taxonomy typically treats this as part of the larger Pheidole genus. The type specimens were collected from Tucumán and later studied by Wilson in 2003 as part of his revision of New World Pheidole species ^[3].

Distribution and Endemism

This is a highly restricted endemic species found only in the Yungas of northwestern Argentina. Within the Yungas, P. subaberrans has been recorded from premontane forest (300-600m elevation) and basal forest (900-1200m elevation) ^[2]. This restricted distribution makes it particularly vulnerable to habitat loss.

Ecological Role in the Yungas

In the Yungas ecosystem, Pheidole species play roles as predators and scavengers. Research shows P. subaberrans is a significant prey item for two toad species in the genus Melanophryniscus ^[4]. This indicates the species is common in its habitat and actively forages on the forest floor.

Keeping an Undescribed Species

Pheidole subaberrans represents a challenge as there are no established care protocols. If you obtain a colony, start with standard Pheidole care: test tube setups for founding, keeping them at room temperature (20-24°C), and offering sugar water and small protein sources. Document your observations to contribute to antkeeping knowledge.

Housing Recommendations

For founding colonies, use test tube setups with a water reservoir and cotton plug. Once the colony reaches workers, consider moving to a formicarium like Y-tong or plaster nests. Provide a humidity gradient based on their natural habitat. Standard escape prevention is recommended.
