Bothriomyrmex anastasiae

Quick Summary

• Difficulty: Unknown, likely Expert
• Origin & Habitat: Caucasus region of Russia (Krasnodar Territory). Type specimens collected from pine forest habitats in southeastern Gelendzhik and Markotkh Range near Kabardinka ^[1][2].
• Colony Type: Unconfirmed. Colony structure has not been documented in scientific literature.
• Size & Growth:
  • Queen: Size data unavailable, no body measurements (TL) exist for this species. Cephalic index (CI) of queens is 94-96 ^[1].
  • Worker: Size data unavailable, no body measurements (TL) exist for this species. Cephalic index (CI) of workers is 91-93 ^[1].
  • Colony: Unknown, no colony size data exists
  • Growth: Unknown
  • Development: Unknown, no development data exists for this species (Development timeline unconfirmed.)
• Antkeeping:
  • Temperature: Likely 22-26°C based on genus patterns and Russian Caucasus climate, no direct data exists. Start at room temperature (20-24°C) and observe colony activity.
  • Humidity: Moderate, typical for temperate forest ants. Keep nest substrate slightly moist but not waterlogged.
  • Diapause: Likely yes, temperate species from Russia probably requires winter rest. Specific duration unknown.
  • Nesting: Natural nesting is in soil or under stones in forest habitats. A test tube setup or small Ytong nest would be appropriate starting points. Avoid overly dry conditions.
• Behavior: Behavior is unstudied. Based on genus patterns, they are likely relatively docile and non-aggressive. Workers are small, so standard escape prevention measures should work. No data on sting potency, but Bothriomyrmex ants are not known for painful stings.
• Common Issues: extreme data scarcity makes reliable care recommendations nearly impossible, no information on founding behavior, unknown if claustral or semi-claustral, no confirmed diet information, hibernation requirements unstudied, temperate origin suggests need for winter rest, no data on colony structure, single or multiple queens

Species Overview and Identification

Bothriomyrmex anastasiae is a small dolichoderine ant described by Dubovikoff in 2002 from specimens collected in Russia's Krasnodar Territory in the Caucasus region ^[1]. Workers are pale yellowish-brown with a shallow metanotal depression and propodeum that weakly protrudes above the mesonotum. The eyes are positioned on the facial surface and fully visible, separated from the lateral head margin ^[1]. Queens are darker brown with a notably broad, short head that slightly narrows downward, and a slightly concave occipital margin. The scape has short semi-erect hairs and extends beyond the occipital head margin by no more than its maximum diameter ^[1]. This species belongs to the Bothriomyrmex communista group and is distinguished from related species by head proportions and shorter scape length ^[1]. The type series was collected from pine forest habitats in July 1956 by K.V. Arnoldi.

Distribution and Habitat

Bothriomyrmex anastasiae is known only from the Caucasus region of Russia, specifically the Krasnodar Territory ^[1][2]. The type localities are Dzhankhot (southeastern Gelendzhik) and Markotkh Range near Kabardinka, both coastal areas on the Black Sea ^[1]. The original collection occurred in pine forest habitat, indicating this species prefers forested areas in warm temperate climates ^[1]. The species has been recorded in Russia's European part (North Caucasus) according to the annotated catalogue of Russian Hymenoptera ^[3]. Beyond these records, nothing is known about the species' broader distribution or habitat preferences.

What We Don't Know (Data Gaps)

This is one of the least documented ant species in existence. The original description provides only morphological details, absolutely no biological information exists about colony structure, founding behavior, diet, temperature or humidity preferences, nuptial flight timing, or development ^[1]. We do not know if this species is monogyne (single queen) or polygyne (multiple queens). We do not know if the queen seals herself in during founding (claustral) or must forage (semi-claustral). We do not know what they eat or how fast they grow. We do not know if they require hibernation. This species is genuinely understudied. Any care recommendations for this species are at best educated guesses based on genus patterns, not species-specific data.

Genus-Level Inferences for Care

While specific data for B. anastasiae does not exist, Bothriomyrmex is a genus of small dolichoderine ants found primarily in warm regions. Some species in this genus are known to be temporary social parasites of Tapinoma ants, the queen invades a host colony, kills the host queen, and uses host workers to raise her first brood before her own workers take over. It is unknown if B. anastasiae exhibits this behavior. Based on typical dolichoderine care, they likely prefer warm conditions (22-26°C), moderate humidity, and likely eat honeydew and small insects. Test tube setups work well for founding colonies. However, these are all guesses, the only way to learn about this species is through careful observation of captive colonies.

Housing and Setup Recommendations

Since we have no species-specific data, recommendations must be based on general dolichoderine husbandry. Start with a simple test tube setup, a water reservoir with a cotton plug, leading into a dry chamber where the queen can seal herself in if she chooses to. Keep the setup at room temperature (20-24°C) initially and observe. If workers become sluggish, slightly warmer temperatures may help. Maintain moderate humidity, the substrate should feel slightly moist but never waterlogged. For a founding colony, a small Ytong nest can work once the colony reaches 10-20 workers. Since workers are small, use fine mesh on any ventilation holes to prevent escapes. Avoid dry conditions, these are forest ants from a temperate region.

Legal and Ethical Considerations

Bothriomyrmex anastasiae has never been documented in the antkeeping hobby and is not available commercially. If you were to obtain this species, it would almost certainly be from a wild-caught queen from the Caucasus region. Before collecting or keeping this species, research local regulations in Russia regarding ant collection. Additionally, never release non-native ants into the wild, this is particularly important for rarely studied species whose ecological impact is unknown. If you successfully keep and propagate this species, consider documenting your observations and contributing to ant community knowledge bases.
