Procryptocerus regularis

Quick Summary

• Difficulty: Unknown, Insufficient data for reliable assessment
• Origin & Habitat: Neotropical region: Brazil, Argentina (Corrientes and Misiones provinces), and Trinidad and Tobago ^[1]. Inhabits arboreal vegetation in tropical dry forests, including the upper Cauca river valley basin ^[2][5].
• Colony Type: Unconfirmed, no published data on colony structure.
• Size & Growth:
  • Queen: size data unavailable
  • Worker: size data unavailable
  • Colony: Unknown
  • Growth: Unknown
  • Development: Unknown, no development data available for this species (Development timeline has not been studied.)
• Antkeeping:
  • Temperature: As a Tropical Climate Specialist ^[3], keep warm and stable, roughly 22-26°C based on natural habitat. Use a gentle thermal gradient and watch colony activity for signs of stress.
  • Humidity: Arboreal species likely prefer moderate to high humidity. Keep the nest substrate slightly moist but not waterlogged, and provide good ventilation.
  • Diapause: Unknown, as a tropical species, a true diapause is unlikely, but no data confirms this.
  • Nesting: Arboreal, provide a vertical setup with elevated nest chambers. Y-tong (AAC) nests or naturalistic setups work well. Avoid ground-level test tube setups.
• Behavior: Behavior is poorly documented. They are not aggressive and have been hand-collected in the field ^[6]. Escape risk is unknown due to lack of size data, but use standard barriers and seal all gaps. Activity level appears low to moderate.
• Common Issues: no published care information makes reliable guidance impossible, arboreal nature requires specialized housing that many keepers cannot provide, humidity and temperature needs are poorly understood, risking colony failure, very limited availability in the hobby means few experienced keepers can offer help

Nest Preferences and Housing

Procryptocerus regularis is an arboreal species, nesting in vegetation above ground ^[2]. In captivity, avoid standard test tube setups and instead provide a vertical arrangement with elevated nest chambers. Y-tong (AAC) nests with small chambers work well, or you can use plaster or 3D-printed nests. The nest should be positioned above the outworld. Multiple small chambers connected by narrow passages allow the colony to regulate humidity by moving around.

Feeding and Diet

The natural diet of Procryptocerus regularis is unknown. There are no published studies on their feeding habits. In captivity, offer a variety of sugar sources (honey water, sugar water) and small protein sources (fruit flies, pinhead crickets). Observe what your colony accepts and adjust. Remove uneaten food to prevent mold.

Temperature and Seasonal Care

This species is classified as a Tropical Climate Specialist ^[3], meaning it prefers warm, stable conditions. Based on its native range (Brazil, Argentina, Trinidad and Tobago), maintain temperatures roughly in the low-to-mid 20s°C (22-26°C). Use a heating cable on one side to create a gentle gradient and watch where the colony clusters. They likely do not require a hibernation period, but may slow down in cooler rooms.

Behavior and Temperament

Procryptocerus regularis is not considered aggressive. Workers have been hand-collected in the field ^[6], suggesting they are not defensive. They have a stinger (like most Myrmicinae), but it is unlikely to be medically significant. Escape risk is unknown because worker size has not been measured, assume they are small and use fine mesh or fluon barriers. Activity level appears low to moderate.

Colony Establishment and Growth

No information exists on founding behavior. The queen may be claustral, but this is speculation. Colony growth rate and size are unknown. Be patient with any founding colonies and minimize disturbance. The first workers (nanitics) may be smaller than mature workers, but this is also unconfirmed.
