Tetramorium dogieli

Quick Summary

• Difficulty: Unknown
• Origin & Habitat: Kenya and Tanzania (Afrotropical region). Recorded at 800-900 m elevation in highland areas near Naivasha ^[2][1].
• Colony Type: Unknown, no colony or queen specimens have ever been documented
• Size & Growth:
  • Queen: Unknown, not described ^[1]
  • Worker: ~2.5 mm total length ^[1]
  • Colony: Unknown, no colony data exists
  • Growth: Unknown
  • Development: Unknown, no data, completely unstudied (No developmental data exists for this species. Any estimate would be pure speculation.)
• Antkeeping:
  • Temperature: No species-specific data. Based on highland origin, start around 20-24°C and adjust as needed. Room temperature is likely fine, but monitor carefully.
  • Humidity: Unknown, keep the nest substrate slightly moist but not waterlogged. Provide a humidity gradient so the ants can choose.
  • Diapause: Unknown, likely not required given the tropical highland origin, but no data supports this.
  • Nesting: Unknown, presumably ground-nesting. A simple test tube setup or a small soil nest should work for starting out.
• Behavior: Behavior is completely unstudied. As a Myrmicinae (Crematogastrini), defense is by smearing a venom with a modified stinger. Workers are tiny, so escape prevention is critical, they can slip through gaps smaller than 1 mm. Use fine mesh and seal all connections.
• Common Issues: no biological data exists, all care is guesswork, colony may fail without warning., tiny size (2.5 mm) makes escape prevention extremely difficult, use ultra-fine mesh and absolutely tight seals., lack of known founding behavior means you might not even get a queen to lay eggs., unknown dietary needs, you'll have to experiment with different prey sizes and carbohydrate sources., if the species ever gets established outside its native range it could become invasive (see warning below).

Background and Identification

Tetramorium dogieli was described by Karavaiev in 1931 based on a single worker from Naivasha, Kenya ^[1]. That type specimen has since been lost, making it hard to confirm identity. Bolton (1980) placed it in the squaminode-group and noted it may actually be the same species as Tetramorium nube, separated only by slight differences in head sculpture and size (worker TL 2.5 mm) ^[1]. Because the antennae were not clearly described, even the number of antennal segments (12 vs 11) is uncertain ^[1]. The species is known from only that one specimen and a few later records in Cameroon ^[2].

Distribution and Habitat

The only confirmed native range is Kenya and possibly Tanzania ^[1]. Additional specimens have been collected at 800-900 m elevation in Cameroon, suggesting a patchy highland distribution across central Africa ^[2]. The type locality, Naivasha, is a highland area in the Kenyan Rift Valley. Nothing is known about its specific nest sites or microhabitat, but related Tetramorium in the region nest in soil, under stones, or in leaf litter.

Care Recommendations (All Inferred)

Because no biological data exists for this species, every care suggestion is a guess based on general Tetramorium husbandry. Keep the nest at room temperature (20-24°C) and provide a substrate that stays slightly moist but not wet. A test tube setup is the safest way to start a colony. For escape prevention, use the finest mesh you can find (at least 0.5 mm openings) and seal every joint with silicone or PTFE tape. These ants are tiny enough to slip through standard cotton plugs.

Feed small prey: fruit flies, springtails, or pinhead crickets. Offer sugar water or honey for carbohydrates. Start with tiny amounts and increase only as the colony grows. Be prepared for failure, this species has never been kept in captivity.

Growth and Development

Absolutely no developmental data exists for Tetramorium dogieli. The egg-to-worker time, growth rate, and colony size are all completely unknown. Do not expect a smooth, predictable colony founding. If you do succeed, consider documenting and sharing your observations, any information would be valuable to myrmecology.
