Myrmecina bawai

Quick Summary

• Difficulty: Unknown, likely Moderate
• Origin & Habitat: Eastern Himalayas, India (Mizoram state), Phawngpui National Park at 1619m elevation. Lives in sub-tropical broadleaf and tropical evergreen forest with ~70% canopy cover, receiving ~2500mm annual rainfall ^[1].
• Colony Type: Colony structure is unconfirmed. Only two workers have been collected from the wild.
• Size & Growth:
  • Queen: Not yet described
  • Worker: 3.67-3.97mm total length ^[1]
  • Colony: Unknown, only two workers have ever been collected in the wild
  • Growth: Unknown
  • Development: Unconfirmed (Development timeline has not been studied for this species.)
• Antkeeping:
  • Temperature: Keep around 20-24°C. The natural habitat ranges from 2-30°C annually, but they live in shaded forest understory where conditions are more stable. Room temperature (around 22°C) is likely suitable.
  • Humidity: High humidity required. The type locality receives ~2500mm annual rainfall and has dense canopy cover creating a constantly damp environment. Keep the nest substrate consistently moist but not waterlogged. Mist the outworld occasionally.
  • Diapause: Likely yes, the natural habitat experiences cold winters with temperatures near 2°C. Expect a winter rest period of 2-3 months at around 10-15°C.
  • Nesting: Probably prefers naturalistic setups with moist substrate. In the wild they likely nest in soil or under debris on the forest floor. A test tube setup works for founding colonies, for established colonies, a plaster nest or naturalistic setup with damp soil works well.
• Behavior: These ants are very small and likely non-aggressive. They probably forage on the forest floor, potentially feeding on small invertebrates, honeydew, and decaying organic matter like most Myrmecina species. Their tiny size means they cannot sting humans, they are harmless to keepers. Escape prevention should be taken seriously due to their small size, fine mesh barriers are recommended. As Myrmicinae ants, they have a modified stinger used to smear venom onto enemies rather than pierce flesh.
• Common Issues: very small size makes escape prevention critical, use fine mesh and tight-fitting lids, high humidity requirements can lead to mold if ventilation is poor, limited data means care requirements are estimates based on genus, adjust based on colony behavior, small colony size means colonies are fragile and sensitive to disturbance, newly described species has no established husbandry guidelines in the hobby

Discovery and Naming

Myrmecina bawai was described in 2021,making it one of the newest ant species. It was discovered in Phawngpui National Park in Mizoram, India, a protected area centered around the Blue Mountain, which at 2157m is the highest peak in the region. The species was named to honor Prof. Kamaljit S. Bawa, founder president of ATREE (Ashoka Trust for Research in Ecology and the Environment), on the organization's 25th anniversary. Only two workers have ever been collected, both in pitfall traps set 200 meters apart ^[1].

Natural Habitat and Climate

This species comes from a high-altitude, humid forest environment in the Eastern Himalayas. The Phawngpui National Park covers about 50 square kilometers of sub-tropical broadleaf and tropical evergreen forest at elevations around 1600m. Annual rainfall approaches 2500mm. Temperature ranges from 2°C in winter to 30°C in summer, but these ants live under dense canopy where conditions are more stable and humid year-round. The type locality is described as a shaded region with about 70% canopy cover. For keeping success, replicate these damp, shaded forest floor conditions, think consistently moist substrate, minimal direct light, and stable temperatures in the low 20s Celsius ^[1].

Appearance and Identification

Workers are tiny at approximately 3.7-4.0mm total length. Their body is yellow with a dark tinge, giving them a somewhat amber appearance. The most distinctive features are their very small eyes (only 0.04-0.05mm, barely visible), rough wrinkled texture on the head and mesosoma, and two small denticles on the propodeum. They have 12-segmented antennae with a 3-segmented club. Their body is covered in abundant long erect hairs. Compared to the similar Myrmecina taiwana, M. bawai is larger, has distinct rugae with dense punctures between them, and has a textured gaster rather than a smooth one ^[1].

Housing and Nesting

Since this is a newly described species with no established husbandry history, adapt based on what is known about the genus. Myrmecina ants are typically ground-dwellers that nest in soil or under debris on forest floors. For founding colonies, a standard test tube setup works well, keep the water reservoir moderate to avoid flooding, and wrap the tube in darkness to simulate the shaded forest floor environment they naturally prefer. For established colonies, consider a plaster nest or naturalistic setup with damp soil. Whatever you choose, maintain high humidity and avoid letting the substrate dry out. These tiny ants need tight escape prevention, even small gaps that seem insignificant can allow escape.

Feeding and Diet

The specific diet of Myrmecina bawai has not been studied, but Myrmecina genus members are typically omnivorous, feeding on small invertebrates, honeydew from aphids, and decaying organic matter. For your colony, offer a varied diet: sugar water or honey occasionally, small live prey like fruit flies or springtails, and protein sources like small mealworms or cricket pieces. Feed small amounts, these tiny ants do not need much. Remove uneaten food to prevent mold in the humid environment they require.

Temperature and Seasonal Care

The natural habitat experiences significant seasonal temperature variation (2-30°C annually), but these ants live under dense canopy where conditions are more moderate. Aim for stable temperatures around 20-24°C, room temperature is likely suitable for most keepers. A very gentle temperature gradient allows the colony to choose their preferred spot. For winter, expect a diapause period. In their natural habitat, winter temperatures drop significantly, so reduce temperatures to around 10-15°C for 2-3 months during winter to simulate their natural cycle. This rest period is important for colony health long-term ^[1].
