Polyrhachis regesa

Quick Summary

• Difficulty: Hard
• Origin & Habitat: Afrotropical region, Ghana and Republic of Congo (Niari Region). Collected from primary forest ^[2][1].
• Colony Type: Unconfirmed, colony structure has not been documented for this species
• Size & Growth:
  • Queen: Size data unavailable
  • Worker: 4.4-4.8mm ^[1]
  • Colony: Unknown, no colony size data available
  • Growth: Unknown
  • Development: Unconfirmed, estimated 6-10 weeks based on typical Formicinae development patterns (Development timeline is not directly documented. Estimates are based on genus-level patterns for small tropical ants.)
• Antkeeping:
  • Temperature: Likely 24-28°C based on primary forest habitat in central Africa. Provide a warm gradient if possible.
  • Humidity: Keep substrate consistently moist but not waterlogged, reflecting primary forest conditions.
  • Diapause: No, tropical species from Congo and Ghana does not require hibernation
  • Nesting: No specific nesting data available. Provide humid, shaded areas using plaster or soil nests with good moisture retention.
• Behavior: Behavior is unstudied. As a Formicinae member, they spray formic acid for defense rather than sting. Their small size suggests moderate escape risk, use standard barriers like Fluon.
• Common Issues: limited species-specific care information makes proper husbandry challenging., tropical humidity requirements may be difficult to maintain consistently., wild-caught colonies may have parasites or diseases not yet documented., small size may require fine mesh barriers for containment., primary forest habitat needs stable conditions, avoid temperature and humidity fluctuations.

Identification and Morphology

Polyrhachis regesa workers measure 4.4-4.8mm in total length. They are black with a shinier gaster, covered in erect white hairs that are longer on the tibiae and scapes. The propodeum has minute tubercles, and the petiole has dorsal and lateral spines. This species belongs to the revoili species-group and can be distinguished from Polyrhachis otleti by propodeal tubercles instead of ridges ^[1].

Distribution and Habitat

Polyrhachis regesa is known from Ghana and the Republic of Congo (Niari Region) ^[2][1]. Congo specimens were collected from primary forest using fogging, indicating a humid tropical forest environment. Ghana specimens were collected using pyrethrum knock-down, suggesting surface activity. No specific microhabitat details are documented.

Housing and Nesting

Provide a humid environment with stable temperatures around 24-28°C. Use plaster or soil nests with moisture retention, and include both humid and slightly drier areas for self-regulation. Ensure tight connections between nest and outworld to prevent escapes, and maintain adequate ventilation to avoid mold.

Feeding and Diet

No specific dietary data is documented. Offer sugar sources like honey water and small protein prey such as fruit flies or micro crickets. Adjust offerings based on colony acceptance.

Temperature and Seasonal Care

Based on collection from tropical primary forest, maintain warm temperatures of 24-28°C with a gentle heat gradient. Avoid fluctuations and drafts. Humidity should be high, reflecting forest floor conditions. ^[2]

Behavior and Defense

Specific behaviors are unstudied. As a Formicinae, they defend by spraying formic acid. Their small size suggests moderate escape risk, use Fluon barriers as a precaution. ^[1]
