Temnothorax gui

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Yunnan Province, China, Shanglama Village, at 2180m elevation in forest habitats ^[1][2]
• Colony Type: Unconfirmed, typical Temnothorax are single-queen colonies, but colony structure for this species has not been documented
• Size & Growth:
  • Queen: Unknown, not described
  • Worker: 3.6-4.5mm total length ^[1]
  • Colony: Unknown, typical Temnothorax colonies can reach several hundred workers, but no data for T. gui
  • Growth: Moderate (inferred from related species)
  • Development: Unknown, no documented data (Development timing is unconfirmed, typical Temnothorax take 6-10 weeks at room temperature, but this is speculative)
• Antkeeping:
  • Temperature: No specific data, based on high-altitude origin, moderate temperatures around 20-24°C are likely suitable. Avoid extremes
  • Humidity: No specific data, forest-dwelling ants typically need moderate moisture. Keep nest substrate damp but not waterlogged, with a water source
  • Diapause: Likely required, but unconfirmed, high-altitude Yunnan (2180m) suggests cold tolerance. If attempted, provide 3-4 months at 5-10°C
  • Nesting: Small, dark chambers suit tiny ants. Test tubes or Y-tong (AAC) nests with narrow spaces are recommended. Avoid large, open formicaria
• Behavior: Peaceful and non-aggressive. As a member of Crematogastrini, workers have a reduced, spatulate stinger used to smear venom rather than pierce, they pose no significant threat to humans. Their tiny size (3-4mm) makes escape prevention critical, use fine mesh and barriers. Little else is known about their specific behavior.
• Common Issues: tiny size makes escape likely without fine mesh (≤0.5mm holes) and tight seals, newly described species with very limited care information, be prepared to adapt, high-altitude origin suggests diapause may be important, skipping it may stress the colony, founding behavior unknown, if the queen is claustral, avoid disturbing her during early development, overfeeding can cause mold due to small colony size, offer tiny portions and remove leftovers promptly

Housing and Nest Setup

Because Temnothorax gui is tiny (workers ~4mm), your nest should match their small size. Test tubes work well for housing a single queen or small colony, use a water reservoir (5-10cm of water behind a cotton plug) to keep humidity high. For larger colonies, Y-tong (AAC) nests with narrow chambers are ideal as they mimic the tight, dark spaces these forest ants would naturally use. Avoid spacious, open formicaria, the ants may feel exposed. Use fine mesh (≤0.5mm openings) on ventilation holes to prevent escapes. Keep the nest in a dark place or cover it with an opaque cloth. These recommendations are based on typical needs of small forest Temnothorax, not confirmed for T. gui.

Feeding and Diet

Like most Temnothorax, T. gui is likely omnivorous. Provide a constant energy source such as diluted honey or sugar water (1:1). For protein, offer tiny live prey, fruit flies, pinhead crickets, or small mealworms, sized no larger than the ants themselves. You can also try boiled egg white or commercial ant food. Feed small amounts 2-3 times per week, remove any uneaten food after 24 hours to prevent mold. Always keep a clean water source, like a small water tube or damp cotton ball. These are general recommendations for small myrmicine ants, as no specific dietary data exists.

Temperature and Seasonal Care

No precise temperature requirements are known for this species. Given its origin at 2180m in Yunnan, a moderate, stable temperature like 20-24°C is likely safe. Avoid extreme heat or cold. A gradient (cool side to warm side) allows ants to self-regulate. Whether diapause is mandatory is unknown, but the high-altitude environment suggests a winter rest is natural. If you choose to provide diapause, gradually lower the temperature to 5-10°C over several weeks, maintain for 3-4 months (roughly November-February), then slowly warm back up. During diapause, reduce feeding to a tiny drop of honey once monthly or stop entirely. Monitor the colony closely. ^[1]

Colony Founding

Founding behavior for Temnothorax gui has not been observed. Typical small Temnothorax are claustral (queen seals herself in a chamber and uses stored reserves), but this is speculation. If you have a queen, place her in a small test tube with water and a cotton plug, keep it dark and humid, and disturb her as little as possible. Avoid checking for eggs or larvae for at least two weeks. First workers might appear after several weeks to months, but timing is unknown. Patience is key, disturbing the queen can cause her to eat or abandon brood. If she rejects the tube, try a different setup (e.g., a small soil chamber).

Behavior and Temperament

Temnothorax gui belongs to subfamily Myrmicinae, tribe Crematogastrini, which are known for using a modified, spatulate stinger to smear venom onto enemies rather than piercing them. This defense is more of a deterrent than a threat to keepers. The ants are very small (3-4mm), non-aggressive, and generally calm. Their main challenge is escapability, they can squeeze through tiny gaps. Always use barriers like fluon on nest edges and fine mesh on ventilation. They are active during the day when warm and are not particularly shy. Specific behavioral details for this species are unstudied, so these observations are based on the tribe and genus.
