Proceratium snellingi

Quick Summary

• Difficulty: Expert
• Origin & Habitat: Papua New Guinea, Gulf Province, Ivimka camp in the Lakekamu Basin at 120 m elevation. Found in lowland wet forest habitat, collected from sifted leaf litter ^[1].
• Colony Type: Colony structure is unconfirmed. Based on genus patterns, Proceratium species typically form small colonies with single queens, but this is not confirmed for P. snellingi ^[1].
• Size & Growth:
  • Queen: ~3.0 mm ^[1]
  • Worker: ~2.3 mm ^[1]
  • Colony: Unknown, no data on colony size ^[1]
  • Growth: Unknown
  • Development: Unconfirmed, no species-specific data exists ^[1] (Development time is unknown, based on genus patterns, it may be slow ^[1].)
• Antkeeping:
  • Temperature: Keep at 24-28°C, matching their lowland tropical origin. A gentle gradient is advisable ^[1].
  • Humidity: Keep substrate consistently moist but not waterlogged, as they live in wet forests ^[1].
  • Diapause: No, as a lowland tropical species, they do not require hibernation ^[1].
  • Nesting: In nature, they nest in soil and leaf litter. In captivity, use small test tubes or miniature terrariums with damp substrate ^[1].
• Behavior: Proceratium ants are cryptic and slow-moving. They are predatory on small invertebrates and forage individually. Workers are non-aggressive, but their tiny size means escape prevention is critical ^[2][1].
• Common Issues: complete lack of biological data means care is based on inference, expect experimentation, tiny size makes housing and feeding difficult, slow growth and cryptic behavior can obscure colony health, escape prevention is critical due to minute size, obtaining live colonies is very difficult due to rarity

Housing and Setup

Housing Proceratium snellingi requires small spaces due to their tiny size. A test tube setup works for founding colonies, with water and a cotton plug. For established colonies, use a miniature terrarium with damp soil, leaf litter, and rotting wood to mimic their natural habitat. Provide tight, humid spaces, they do not fare well in large formicaria. Use fine mesh on ventilation holes to prevent escapes ^[1].

Feeding and Diet

Proceratium snellingi is predatory on small invertebrates. Feed live springtails as a primary food source, along with tiny arthropods like fruit flies. Protein is essential, sugar sources may be accepted but are not primary. Remove uneaten prey to prevent mold ^[1].

Temperature and Humidity

Maintain temperatures between 24-28°C, avoiding drops below 22°C. Use a heating mat for a gradient if needed. Humidity should be high, keep substrate moist but not waterlogged. A water reservoir helps maintain moisture ^[1].

Colony Establishment

Establishing a colony is challenging due to rarity. If a queen is obtained, house her in a test tube and leave undisturbed. Founding behavior is unconfirmed, but she may seal herself in. Be patient, as growth is slow ^[1].

Behavior and Observation

Proceratium snellingi is cryptic and slow-moving, often hidden in substrate. Workers forage individually and are non-aggressive. Observation requires patience and magnification. Escape prevention is key due to their small size ^[2][1].
