Bothriomyrmex inquilinus

Quick Summary

• Difficulty: Unknown, likely difficult due to limited data
• Origin & Habitat: North Africa (Tunisia, Algeria) in the Palaearctic region. Type locality is Le Kef, Tunisia at approximately 800 meters elevation ^[1][2].
• Colony Type: Colony structure is unconfirmed. Some Bothriomyrmex species exhibit temporary parasitic behavior during colony founding, but this is unconfirmed for B. inquilinus.
• Size & Growth:
  • Queen: size data unavailable, no direct measurements exist for this species
  • Worker: size data unavailable, no direct measurements exist for this species
  • Colony: Unknown, no colony size data available
  • Growth: Unknown
  • Development: Unknown, no development data available for this species (Development timeline has not been studied. Specific data is lacking.)
• Antkeeping:
  • Temperature: Unconfirmed, likely prefers warm conditions similar to other North African Dolichoderinae. Start around 22-26°C and observe colony behavior.
  • Humidity: Unconfirmed, likely adapted to the semi-arid conditions of Tunisia and Algeria. Moderate humidity (40-60%) is a reasonable starting point based on the species' North African range.
  • Diapause: Unknown, no data on overwintering requirements. North African species may have reduced activity during cooler months but likely do not require true hibernation.
  • Nesting: Unconfirmed, no natural nesting observations documented. Most Bothriomyrmex species nest in soil or under stones in warm, open habitats.
• Behavior: Behavior is poorly documented. The genus Bothriomyrmex is characterized by rapid, erratic movement and workers that readily flee when disturbed. Escape risk is significant given their small size, use fine mesh barriers. Aggression levels are unknown but likely moderate like most Dolichoderinae.
• Common Issues: extremely limited biological data makes captive care highly speculative, no confirmed diet preferences, feeding recommendations cannot be reliably given, colony structure unknown makes queen introduction and colony founding unpredictable, escape prevention is critical due to tiny worker size, wild-caught colonies may have unknown parasites or diseases

Species Overview and Identification

Bothriomyrmex inquilinus is a poorly known ant species described by F. Santschi in 1919 from Tunisia. The type specimens were collected from Le Kef at approximately 800 meters elevation ^[1]. As a member of the Dolichoderinae subfamily, this species shares characteristics with other ants in the genus, including their distinctive tapered gaster shape. The species is considered rare with a limited distribution restricted to North Africa (Tunisia and Algeria) ^[2]. Only the worker and queen castes have been described, the male caste remains undescribed. The taxonomic status has remained stable since being recognized as a distinct species in 1968,after being briefly considered a subspecies of B. atlantis.

Distribution and Habitat

Bothriomyrmex inquilinus is endemic to the western Palaearctic region, specifically found only in Tunisia and Algeria ^[2]. The type locality is Le Kef in Tunisia, at an elevation of approximately 800 meters ^[1]. This region experiences a Mediterranean climate with hot, dry summers and mild, wet winters. The species has been collected at relatively low elevations in mountainous areas. No specific habitat preferences have been documented, but the genus Bothriomyrmex typically inhabits warm, open areas with sparse vegetation.

Taxonomy and Classification

This species was originally described by Felix Santschi in 1919,with type material including syntype workers and a queen ^[1]. The type specimens are housed in collections at the Natural History Museum in Basel (NHMB) and the Museum of Natural History in Geneva (MHNG). The species was once considered a subspecies of Bothriomyrmex atlantis but was elevated to full species status in 1968. The genus Bothriomyrmex belongs to the subfamily Dolichoderinae, which is characterized by ants that have a single petiole (waist segment) and a tapered, pointed gaster. This subfamily includes economically significant invasive species like the Argentine ant (Linepithema humile).

Current State of Knowledge

Bothriomyrmex inquilinus represents one of the least studied ant species in the Palaearctic region. Almost no biological, ecological, or behavioral information exists in the scientific literature. What we know is limited to taxonomic descriptions of the worker and queen castes and their geographic distribution. This species would benefit significantly from field studies to document its nesting preferences, colony structure, diet, and behavior. For antkeepers, this species presents a challenge because no established care protocols exist. Anyone attempting to keep this species should document their observations carefully, as any captive husbandry information would be valuable for advancing our knowledge. The lack of basic biological data makes this species unsuitable for beginners or those seeking well-established care guidelines.
