Nylanderia braueri

Quick Summary

• Difficulty: Hard
• Origin & Habitat: Native to Australia, specifically Queensland (Mackay type locality) ^[2]. Recorded from Solomon Islands ^[3]. Natural habitat unconfirmed.
• Colony Type: Unconfirmed, colony structure not documented in scientific literature.
• Size & Growth:
  • Queen: size data unavailable
  • Worker: size data unavailable
  • Colony: Unknown, no colony size data available
  • Growth: Unknown
  • Development: Unknown, no development data available (No species-specific data available.)
• Antkeeping:
  • Temperature: Unknown, no species-specific data. Based on genus patterns, aim for warm temperatures, but exact requirements unconfirmed.
  • Humidity: Unknown, no species-specific data. Based on genus patterns, moderate humidity may be suitable.
  • Diapause: Unknown for this species.
  • Nesting: Preferred nesting conditions unconfirmed. Based on genus patterns, soil or small cavities may be suitable.
• Behavior: Behavior unconfirmed. Based on genus patterns, workers are active and fast-moving. As Formicinae, they can spray formic acid when threatened. Escape prevention is critical due to the small size of Nylanderia species.
• Common Issues: Escape prevention is critical due to small worker size, No species-specific care data exists, keepers must rely on genus-level inferences, Growth rate and development timeline are unconfirmed, Hibernation or cool-season requirements are unknown

Species Identification and History

Nylanderia braueri was originally described as Nylanderia braueri by Mayr in 1868 from worker specimens collected in Mackay, Queensland, Australia ^[2]. The species has undergone several reclassifications over the years, moving through Prenolepis, then Paratrechina (Nylanderia), and finally settling in Nylanderia as currently recognized ^[4]. A subspecies, Nylanderia braueri donisthorpei, was described by Forel in 1908,though the current validity of this subspecies is uncertain. Some researchers have suggested N. braueri may be synonymous with N. glabrior, which was elevated to full species status in 2012,but N. braueri remains recognized as a valid taxon in current checklists ^[2].

Distribution and Range

Nylanderia braueri is native to Australia, with the type locality in Queensland. The species has been recorded from the Solomon Islands, with specimens collected from Guadalcanal in 1954 representing the first record for that region ^[3]. The species appears in surveys of Australian territories, including Barrow Island where it was detected only in non-indigenous species (NIS) surveys ^[5]. This suggests some capability for dispersal, though its established range remains primarily Australia and neighboring Pacific islands.

Identification Notes

Workers of N. braueri are small ants, though exact body size data is unavailable. Key identification features include mandibles armed with six or seven teeth and antennae with erect setae (bristles standing up from the surface) ^[1]. The genus Nylanderia can be distinguished from similar genera like Paratrechina by certain morphological characteristics, and the species-level identification typically requires examination of microscopic features.

Care and Keeping Uncertainty

This species has not been studied in captivity, and almost no scientific data exists on its biology. All care information in this caresheet represents either direct data from limited specimens or inferences from genus-level patterns. Keepers should monitor colonies closely and adjust care based on observed behavior. This species is best suited for experienced antkeepers comfortable with uncertainty.
