Aenictus humeralis

Quick Summary

• Difficulty: Expert
• Origin & Habitat: Afrotropical region, recorded from Mali (Bamako), Senegal, and Sudan ^[1][2]. Specific habitat preferences are unknown, though the type locality is in the Middle Niger region.
• Colony Type: Unknown. Army ants (Dorylinae) typically exhibit complex social structures with multiple reproductive queens and reproduce by colony fission rather than single-queen founding, but specific colony structure for this species is unconfirmed.
• Size & Growth:
  • Queen: Unknown, no queen specimens have been described in scientific literature.
  • Worker: Unknown, no worker specimens have been described. Related Aenictus species workers are typically small, but this is unconfirmed for this specific species.
  • Colony: Unknown. No colonies have been documented in scientific literature.
  • Growth: Unknown
  • Development: Unknown. No developmental data exists for this species. (Army ant reproduction typically occurs through colony fission rather than single-queen founding.)
• Antkeeping:
  • Temperature: Unknown. Temperature requirements are unconfirmed for this species.
  • Humidity: Unknown. Humidity requirements are unconfirmed for this species.
  • Diapause: Unknown. Diapause requirements are unconfirmed for this species.
  • Nesting: Unknown. Army ants are nomadic and form temporary bivouacs rather than permanent nests, but specific nesting behavior for this species is unconfirmed.
• Behavior: Unknown. Specific temperament data is lacking for this species. Army ants are typically group predators, but behavior cannot be confirmed without worker observations.
• Common Issues: no worker or queen specimens have been described, making identification and care impossible., army ant biology requires massive foraging spaces and constant supplies of prey that standard ant keeping setups cannot provide., lack of any colony-level data means captive keeping is not currently possible., nomadic behavior means they do not stay in one nest location, requiring specialized enclosures.

Taxonomy and Known Specimens

Aenictus humeralis was described by Santschi in 1910 based solely on male specimens collected by A. Chevalier in 1900 from Bamako in the Middle Niger region of Mali ^[2]. The type material consists of syntype males, with one specimen now housed in Basel lacking its head and genital apparatus ^[3]. Males measure approximately 8mm and display intermediate characteristics between related species, with distinctive dirty grayish-yellow thoraxes contrasting with dark brown heads ^[2]. Two subspecies were later recognized: Aenictus humeralis chevalieri (entirely reddish-yellow) and Aenictus humeralis viridans ^[1]. No worker or female reproductive specimens have been described in the available scientific literature, leaving the species' social structure and colony appearance completely unknown.

Why This Species Is Not Suitable for Captivity

You should not attempt to keep Aenictus humeralis. First, the species is known only from male specimens, meaning no one knows what the workers look like, how large the colonies grow, or what they eat ^[2]. Second, as an army ant (subfamily Dorylinae), they likely exhibit nomadic behavior, constantly moving their entire colony rather than staying in one nest. Army ants form temporary living structures called bivouacs using their own bodies, not soil or wood cavities. Third, army ants require enormous foraging territories and massive amounts of prey that cannot be provided in standard ant farms or formicariums. Without basic biological data and given their specialized army ant lifestyle, captive keeping is not possible with current knowledge.

Distribution and Climate

Records place this species in the Afrotropical region, specifically Mali (Bamako), Senegal, and Sudan ^[1]. The type locality in Mali sits in the Middle Niger region with a tropical climate. Specific microhabitat data is absent from scientific literature.
