Aphaenogaster mauritanica

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Northwest Africa (Morocco, Algeria, Tunisia), cork oak forests and mountainous regions in the Atlas ranges at approximately 34°N latitude ^[6][4][3].
• Colony Type: Unconfirmed, colony structure data unavailable for this species.
• Size & Growth:
  • Queen: Size data unavailable, no measurements published for this species.
  • Worker: Size data unavailable, no measurements published for this species.
  • Colony: Unknown, no colony size data published for this species.
  • Growth: Unknown
  • Development: Unknown, no development data published for this species. (Development timeline unconfirmed. Monitor your colony for brood development patterns.)
• Antkeeping:
  • Temperature: Keep at 20-25°C during active season. Provide winter rest at 10-15°C for 3-4 months. This species inhabits Mediterranean climates at 34°N latitude with seasonal variation ^[6].
  • Humidity: Moderate humidity, provide damp nest material with some drier areas available.
  • Diapause: Yes, likely required during winter months based on Mediterranean climate origin ^[6].
  • Nesting: Non-hypogaeic (surface-dwelling) ^[5]. Use shallow naturalistic setups with stones or cork bark, or Y-tong nests with moderate chamber depth. Avoid deep soil setups.
• Behavior: Non-hypogaeic forager that searches on the surface rather than digging deep ^[5]. Likely a generalist scavenger typical of the genus. Escape risk is moderate.
• Common Issues: rarity makes acquisition difficult, this species is rarely collected and uncommon in the wild ^[4][5]., founding behavior unconfirmed, monitor queens carefully to determine if they need food during founding., hibernation timing unclear, observe colony for seasonal activity slowdown to determine when to cool them., easily confused with similar species, verify origin as Maghreb region rather than Europe ^[1].

Taxonomy and Identification

Aphaenogaster mauritanica was formally recognized as a distinct species in 2023, when it was confirmed as the senior synonym (the correct name) for populations previously called Aphaenogaster mauritanica and Aphaenogaster mauritanica ^[1]. Workers can be identified by their membership in the gibbosa species group: they have triangular spines on the thorax with sharp tips, and their antennae stems lack lengthwise ridges but carry hairs longer than half the stem's width ^[2]. They differ from European Aphaenogaster gibbosa and Moroccan Aphaenogaster theryi in subtle morphological details ^[1]. If you acquire these ants, verify their origin as Maghreb (Northwest Africa) rather than Europe to ensure correct identification.

Natural Habitat and Distribution

This species lives in the Maghreb region, specifically Morocco, Algeria, and Tunisia ^[3]. They favor cork oak forests (called Subéraie) and mountainous areas in the Atlas ranges, particularly in Moyen and Haut Atlas regions ^[4]. Despite their broad range across three countries, they are rarely collected, they have been found in only 8 localities total, 6 of which are in Morocco ^[4]. They represent only 0.16% to 0.76% of ants captured in forest surveys ^[4][5]. They are non-hypogaeic, meaning they do not nest deep underground but rather live in surface-level cavities or under stones ^[5]. Their habitat at approximately 34°N latitude experiences hot, dry summers and mild, wet winters typical of Mediterranean climates ^[6].

Nesting and Housing

Because Aphaenogaster mauritanica is non-hypogaeic, they do not require deep substrate for nesting ^[5]. In captivity, provide a naturalistic setup with flat stones, cork bark, or rotting wood pieces where they can create shallow chambers. Alternatively, a Y-tong or plaster nest with moderate chamber depth works well. Ensure the nest has areas of damp soil or plaster alongside drier sections so the colony can regulate their microclimate. Avoid deep soil-filled containers designed for fully subterranean species.

Temperature and Seasonal Care

Coming from Mediterranean climates at 34°N latitude, these ants need a winter rest period (diapause) when temperatures drop ^[6]. Keep them at 20-25°C during the active season (spring through autumn), then gradually cool them to 10-15°C for 3-4 months during winter. If the colony shows reduced activity and stops brood development in autumn, this signals they are ready for cooling. Do not let them overheat above 30°C, as they inhabit extratropical regions rather than tropical ones ^[6].

Feeding and Diet

While specific diet studies are lacking for this species, Aphaenogaster species are typically generalist scavengers and predators. Offer a variety of foods including small insects (fruit flies, pinhead crickets), seeds, and sugar sources like honey water or sugar water. They likely collect honeydew and scavenge dead insects in the wild. Provide protein twice weekly and keep sugar water available constantly. Watch what your specific colony accepts, as preferences may vary.

Colony Founding

The founding behavior of Aphaenogaster mauritanica remains unconfirmed by research. Set up founding queens in test tubes or small founding chambers with a water reservoir. Monitor whether the queen accepts food, if she ignores food, she may be claustral (seal herself in and live off stored body fat), if she eats, she may be semi-claustral (needing to forage during founding). Without published data, you will need to observe your specific queen to determine her behavior.
