Proceratium digitospinum

Quick Summary

• Difficulty: Hard
• Origin & Habitat: Guangxi, China, evergreen broad-leaved primitive forests at 160 m elevation ^[1]
• Colony Type: Unconfirmed colony structure, no specific data available
• Size & Growth:
  • Queen: Size data unavailable, no total length measurements for queens in research
  • Worker: 3.93-3.97 mm ^[1]
  • Colony: Unknown, no data on colony size
  • Growth: Slow, inferred from genus patterns
  • Development: Unknown, no data available (No direct development data exists for this species)
• Antkeeping:
  • Temperature: Temperature needs are unclear, start around 22-26°C and observe, based on their subtropical habitat ^[1]
  • Humidity: Keep substrate consistently moist but not waterlogged, as they live in humid forests ^[1]
  • Diapause: Unknown, no data available
  • Nesting: Soil-nesting species, prefers naturalistic setups with moist substrate. Based on habitat, Y-tong or plaster nests with small chambers work well ^[1]
• Behavior: Proceratium digitospinum is likely cryptic and slow-moving, typical of the genus. Workers probably forage individually in the soil and rely on touch or vibration due to reduced eyes. They are not aggressive and pose no sting risk. Escape prevention is critical due to their tiny size (under 4 mm).
• Common Issues: escape prevention is critical, their tiny size means they can slip through standard barriers, newly described species means limited care information, some trial and error expected, high humidity needs can cause mold if ventilation is poor, wild-caught colonies may be difficult to find as they're newly described and rare

Housing and Nest Setup

Proceratium digitospinum is a soil-nesting species from humid forest environments ^[1]. For captivity, use a naturalistic setup with moist substrate or a Y-tong/plaster nest with small chambers scaled to their tiny size. Start with standard Proceratium care: high humidity, stable temperatures in the low-to-mid 20s°C, and minimal disturbance ^[1]. Test tube setups work for founding colonies but monitor humidity carefully.

Feeding and Diet

Proceratium ants are predators that hunt small invertebrates in the soil. In captivity, offer small live prey like springtails and fruit flies. Protein from live prey is essential, sugar sources may be accepted occasionally. Feed small prey items 2-3 times per week, adjusting based on consumption. Remove uneaten prey to prevent mold.

Temperature and Seasonal Care

Keep Proceratium digitospinum at 22-26°C with stable temperatures, based on their subtropical habitat ^[1]. A heating cable on one side creates a gentle gradient. Avoid temperature extremes. True diapause may not be required, but reduced feeding during cooler months is possible.

Behavior and Handling

This is a cryptic, slow-moving species typical of the Proceratium genus ^[1]. Workers likely forage individually through the soil. They are not aggressive and their tiny size means they cannot sting humans effectively. Escape prevention is critical, use fine mesh and tight-fitting lids.

Colony Establishment

As a newly described species, Proceratium digitospinum is rare in the antkeeping hobby. If you obtain a founding queen, expect slow growth and maintain consistent care conditions. Document development to help build knowledge for this species.
