Polyrhachis decellei

Quick Summary

• Difficulty: Unknown
• Origin & Habitat: Ghana and the Central African Republic in forest zones ^[2].
• Colony Type: Unconfirmed, no species-specific data on queen number or social structure.
• Size & Growth:
  • Queen: Size data unavailable, no measurements for queens.
  • Worker: ~7.4-7.8 mm ^[1]
  • Colony: Unknown for this species.
  • Growth: Unknown.
  • Development: Unconfirmed, no species-specific data. (Estimates based on typical Formicinae patterns at 24-28°C.)
• Antkeeping:
  • Temperature: Aim for 24-28°C as a starting point, based on tropical forest habitat ^[2].
  • Humidity: Keep substrate moderately moist with a gradient for self-regulation ^[2].
  • Diapause: Unlikely, tropical species typically do not require hibernation ^[2].
  • Nesting: Based on genus patterns, they likely nest in rotting wood or soil, use Y-tong (AAC) nests or formicaria with substrate.
• Behavior: Behavior unstudied. Based on genus patterns, they are docile and forage individually. Defense includes spines and formic acid spray from an acidopore, as typical for Formicinae. Escape risk is moderate due to medium size, standard barriers work well.
• Common Issues: temperature stress, keep above 20°C to avoid cold sensitivity., humidity issues, maintain moist substrate to prevent drying or mold., escape risk, medium-sized ants may explore gaps, ensure secure barriers.

Appearance and Identification

Polyrhachis decellei workers are 7.4-7.8 mm long, black with dark legs, and have dense golden pubescence longer on the mesosoma. They have spines on the pronotum and propodeum, long dorsal spines on the petiole, and a pair of erect hairs on the head vertex ^[1]. The eyes are small and round, helping distinguish them from similar species.

Natural Distribution and Habitat

This species is known from Ghana and the Central African Republic in forest zones ^[2]. Type specimens were collected in June and July, during the wet season in Ghana.

Nest Preferences and Housing

Specific nesting habits are unknown, but Polyrhachis ants generally nest in rotting wood, under bark, or in soil cavities. For captivity, use Y-tong (AAC) nests or formicaria with soil or plaster substrates that can hold moisture. Provide chambers scaled to their 7-8 mm size with good ventilation. ^[2]

Feeding and Diet

The diet is unstudied, but Polyrhachis ants are omnivorous. Offer sugar sources like honeydew or sugar water, and protein from small insects. Remove uneaten food promptly to prevent mold.

Temperature and Seasonal Care

As a tropical species, maintain warm temperatures around 24-28°C year-round. Provide a temperature gradient for self-regulation. Avoid temperatures below 20°C.

Behavior and Temperament

Behavior is unstudied, but genus patterns suggest docility and individual foraging. Defense includes spines and formic acid spray. Escape risk is moderate, use standard barriers for medium-sized ants.
