Platythyrea schultzei

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Native to the Afrotropical region, found in savanna and woodland habitats across southern and eastern Africa ^[1]. In South Africa, they are recorded in areas like Kruger National Park and act as a negative indicator taxon decreasing with elevation above 1200m ^[4].
• Colony Type: Queenless, reproduces via gamergates (mated workers). Single gamergate species with no morphological queen caste ^[2][3].
• Size & Growth:
  • Queen: N/A, queen caste absent ^[2]
  • Worker: Size data unavailable, no total length measurements in context
  • Colony: Up to 31 workers ^[2]
  • Growth: Slow
  • Development: Unknown, not directly studied (Development timeline unconfirmed. Based on typical Ponerinae patterns, expect several months from egg to adult worker.)
• Antkeeping:
  • Temperature: Keep at warm temperatures, around 22-25°C, based on African habitats ^[1].
  • Humidity: Provide a humidity gradient with consistently moist substrate but avoid waterlogging ^[1].
  • Diapause: Unknown
  • Nesting: Test tubes or Y-tong nests work well. They prefer tight, enclosed spaces ^[1]. Provide a small outworld for hunting and foraging with escape prevention ^[1].
• Behavior: Temperament is unconfirmed, but as Ponerinae, they may be defensive. Workers are predatory and will hunt small invertebrates ^[2]. Escape prevention is important as workers are agile and can climb smooth surfaces ^[1].
• Common Issues: small colony size means losses have big impact, a single worker death is significant in colonies of around 20 workers., queenless system is fragile, if the gamergate dies and no replacement is mated, the colony cannot recover., lack of documented captive breeding means establishing a colony from wild-caught specimens is challenging., predatory diet requires constant live prey, they cannot survive on sugar alone.

Understanding the Queenless System

Platythyrea schultzei has completely lost the queen caste. Instead, reproduction is handled by gamergates, workers that have mated and can lay fertilized eggs ^[2]. Mated workers integrate back into the workforce and monopolize egg-tending tasks ^[5]. Each colony typically has just one gamergate that does most of the egg-laying ^[2].

For antkeepers, this means you cannot look for a queen, there isn't one. You need to locate a colony with a functional gamergate. The system is regulated: virgin workers do not develop eggs when a mated worker is present ^[5]. If the gamergate dies and no replacement is available, the colony cannot produce new workers and will eventually die out.

Feeding and Diet

As Ponerinae ants, Platythyrea schultzei are predatory and need a protein-rich diet. They hunt small invertebrates including springtails, fruit flies, and small beetles ^[1]. In captivity, offer small live prey items 2-3 times per week. Remove uneaten prey within 24 hours to prevent mold. Protein should form the bulk of their diet, though sugar water can be offered occasionally for energy ^[1].

Housing and Nest Setup

Given their small colony size, these ants do well in compact setups like test tubes or Y-tong nests ^[1]. They prefer tight chambers and narrow passages. Provide a small outworld for hunting and foraging. Use a substrate barrier or fluon on the rim to prevent escapes, these ants are good climbers ^[1]. Keep the nest relatively dry compared to many other Ponerinae, excessive moisture can be harmful.

Colony Acquisition and Establishment

Acquiring Platythyrea schultzei is challenging because they are not commonly kept. Your best option is to find an established colony in the wild, looking under stones in their African range ^[1]. You need to locate a colony containing a functional gamergate. Once established, colony growth is slow, and the queenless system means you cannot add a new queen if things go wrong ^[2].

Temperature and Seasonal Care

Keep these ants warm at around 22-25°C, as they originate from warm African habitats ^[1]. A heating cable on part of the nest creates a thermal gradient. Diapause requirements are unknown for this species, many African ants may reduce activity during cooler periods but do not undergo true hibernation ^[1].
