Cephalotes mariadeandrade

Quick Summary

• Difficulty: Unknown, newly described species with no captive care data
• Origin & Habitat: Southeastern Brazil (Minas Gerais, Uberlândia) in Cerrado tropical savanna at 860m elevation ^[1]. Found nesting in trees.
• Colony Type: Colony structure is unconfirmed. Field observations show colonies occupy multiple individual nests on the same tree (polydomous natural history), with four nests documented on a single tree ^[1].
• Size & Growth:
  • Queen: 5.18-5.49mm ^[1]
  • Worker: 2.89-3.16mm ^[1]
  • Colony: Unknown, no colony size data available
  • Growth: Unknown, no development data available
  • Development: Unconfirmed, no captive development data exists for this newly described species (Related Cephalotes species in the genus typically develop in 6-10 weeks at warm temperatures, but this is an estimate for C. mariadeandrade)
• Antkeeping:
  • Temperature: Inferred: Based on origin in Minas Gerais Cerrado (subtropical), aim for roughly 24-28°C. Adjust based on colony activity.
  • Humidity: Inferred: Cerrado has distinct wet (summer) and dry (winter) seasons. Provide moderate humidity with a water tube, allowing the colony to self-regulate.
  • Diapause: Unlikely, being a tropical species from Brazil, diapause is probably not required. No seasonal data available.
  • Nesting: Inferred: Natural observations show tree-nesting behavior with multiple nests on the same tree. In captivity, a Y-tong (AAC) nest or plaster nest with narrow chambers would likely work well. Provide connections between multiple chambers to accommodate their polydomous tendency.
• Behavior: The most notable behavioral trait is their association with Crematogaster ants. Workers were observed running in Crematogaster foraging trails, suggesting aggressive mimicry or parasitic behavior similar to C. specularis. This means they are likely stealthy foragers that exploit other ant species' trails. Workers are small but active. Escape risk is moderate due to their small size, standard escape prevention measures recommended ^[1]. As members of the Myrmicinae subfamily, they possess a stinger but it is not medically significant to humans.
• Common Issues: newly described species means no established care protocols exist, keepers will be pioneers, the possible parasitic relationship with Crematogaster may make them difficult to observe in typical foraging scenarios, polydomous nesting in the wild suggests they may need more chamber space than typical single-nest setups, no data on their queen's founding behavior, claustral vs semi-claustral unknown, being from Brazil, they may not tolerate temperatures below 20°C

Discovery and Taxonomy

Cephalotes mariadeandrade was only described in 2021 by Oliveira, Powell, and Feitosa, making it one of the newest described ant species in the hobby. It belongs to the pinelii species group and was discovered in Uberlândia, Minas Gerais, Brazil. The species name honors Maria de Andrade, likely a researcher or contributor to the discovery. The holotype worker was collected in August 2016 along with paratype soldiers, workers, queens, and males from the same location ^[1]. This means captive breeding lineages are extremely rare or non-existent, and most keepers interested in this species would need to source from wild-caught founding queens.

Unique Association with Crematogaster

The most fascinating aspect of C. mariadeandrade is its natural history. Field researchers observed colonies occupying four individual nests on the same tree that was also occupied by an aggressive Crematogaster species. Most remarkably, workers were observed running directly in Crematogaster foraging trails. This behavior is known as aggressive mimicry, the turtle ants have evolved to resemble and move like Crematogaster workers, allowing them to infiltrate the host colony's trails and potentially steal food or other resources. A similar relationship is well-documented in Cephalotes specularis. In captivity, this means you may observe unusual foraging behaviors where they attempt to follow other ant species or move in distinctive trail patterns. This association also suggests they may be sensitive to vibrations and chemical cues ^[1].

Housing and Nesting

Based on field observations showing polydomous nesting (multiple nests on one tree), this species likely benefits from a setup with multiple connected chambers rather than a single compact nest. A Y-tong (AAC) nest or plaster formicarium with several chambers connected by tubing would suit their natural tendencies. The soldiers have distinctive tubercular elevations on their cephalic disc, this is a morphological adaptation for nest entrance defense, similar to other turtle ants. Provide narrow passages that allow soldiers to effectively block entrance points. Given their tree-nesting origin in Cerrado, they likely prefer dry but not arid conditions. A water tube for humidity is recommended, but avoid oversaturation.

Feeding and Diet

Cephalotes are typically omnivorous, feeding on honeydew, nectar, and small insects in the wild. The genus is known for their specialized diet including plant secretions and arthropod prey. Based on their association with Crematogaster and likely mimicry behavior, they may be particularly interested in protein sources and may attempt to steal from other ant colonies. Offer sugar water or honey regularly, along with small protein sources like fruit flies, small mealworms, or other tiny arthropods. The extent of their dietary specializations is unknown since this is a newly described species with no captive feeding observations.

Temperature and Seasonal Care

As a species from Minas Gerais in southeastern Brazil, C. mariadeandrade originates from a subtropical highland climate (Cerrado). Uberlândia at 860m elevation experiences warm temperatures year-round, rarely dropping below 15°C even in winter. This suggests they should be kept warm, roughly 24-28°C, and are unlikely to require any diapause period. Being a tropical species, they probably cannot tolerate prolonged cold temperatures. A heating cable on one side of the nest to create a gentle gradient is advisable, especially if your room temperature is below 24°C. Monitor colony activity, if workers become sluggish, increase temperature slightly. ^[1]

Challenges and Considerations

This is not a species for beginners. Since it was only described in 2021, there is no established captive care protocol, no development data, and likely no established breeding lineages in the antkeeping hobby. You will essentially be a pioneer in keeping this species. Key challenges include: sourcing founding queens (likely requiring field collection in Brazil), determining optimal care conditions through experimentation, and managing their potentially unusual behaviors related to their Crematogaster association. Additionally, their small worker size (under 3mm) means escape prevention must be excellent, standard fine mesh barriers are essential. If you succeed in establishing a colony, you will contribute valuable knowledge to the antkeeping community about this poorly understood species. ^[1]
