Pheidole antranohofa

Quick Summary

• Difficulty: Expert
• Origin & Habitat: Northern Madagascar (Antsiranana province), Parc National de Marojejy at 1325m elevation in montane rainforest. Nests found in rotten logs, root mats, and rotten tree stumps ^[1].
• Colony Type: Colony structure is unconfirmed for this species. Most Pheidole species are monogyne (single queen colonies), but specific data for P. antranohofa is not available.
• Size & Growth:
  • Queen: size data unavailable
  • Worker: ~3-4 mm, inferred from Pheidole genus
  • Colony: Unknown, no colony size data available
  • Growth: Unknown
  • Development: Unconfirmed, estimate 6-8 weeks based on Pheidole genus patterns, but no direct data ^[1] (Development timeline not studied, estimates based on genus patterns for similar species.)
• Antkeeping:
  • Temperature: Based on montane origin, keep around 20-24°C and avoid temperatures above 28°C ^[1]
  • Humidity: Keep nest substrate consistently moist but not waterlogged, as they nest in rotting wood in humid environments ^[1]
  • Diapause: Unconfirmed, observe colony behavior for seasonal slowdowns and consider slight temperature reduction if activity decreases
  • Nesting: Natural nesting in rotten logs, root mats, in captivity, use moist plaster, Y-tong, or naturalistic setups with rotting wood ^[1]
• Behavior: Pheidole species are generally non-aggressive and colony-focused. Major workers process seeds, while minors handle foraging. Escape risk is moderate due to small size, so ensure enclosures are secure.
• Common Issues: newly described species means limited care information, expect a learning curve., high humidity requirements can lead to mold if ventilation is inadequate., no confirmed data on colony founding or development timelines makes captive breeding challenging., montane origin means temperature sensitivity, avoid overheating., limited availability since this species is only known from one protected location in Madagascar.

Origin and Discovery

Pheidole antranohofa was described in 2020 by Salata and Fisher as part of a revision of the Pheidole sikorae species group. The species name comes from its type locality, Antranohofa, in Parc National de Marojejy, Madagascar. It is known only from this location, collected at 1325m elevation in montane rainforest ^[1].

Identification and Morphology

This is a moderately large Pheidole species. Major workers have a yellowish-orange body with darker mandibles and head, while minor workers are dark yellow. Major workers have a sub-oval head that widens posteriorly with dense pilosity and rugofoveolate sculpture. Minor workers are smoother with reduced sculpture. Major workers can be distinguished from Pheidole sikorae by developed mesosoma sculpture, but minors are indistinguishable ^[1].

Natural Nesting Habitat

In the wild, nests are found in rotten logs, root mats, and tree stumps in montane rainforest at 1325m elevation. This indicates a preference for moist, shaded microhabitats with decaying plant material. Replicate these conditions in captivity by providing consistently moist nesting materials ^[1].

Housing and Nest Setup

Use a naturalistic setup with rotting wood pieces or cork bark. Keep nest material moist but not waterlogged. A hybrid setup with a moist plaster or Y-tong nest connected to an outworld works well. Ensure humidity control and provide both moist and slightly drier areas for the ants to regulate conditions ^[1].

Temperature and Humidity Requirements

As a montane species, keep temperatures around 20-24°C and avoid above 28°C. Monitor colony activity: clustering may indicate too cold, while avoiding the nest may indicate too warm. Maintain high humidity (70-85%) with a water reservoir and misting as needed ^[1].

Feeding and Diet

Pheidole ants are generalist foragers. Offer small seeds, sugar water or honey, and protein sources like fruit flies or mealworms. Feed protein 2-3 times weekly and maintain constant sugar availability. Remove uneaten food to prevent mold.
