Simopone matthiasi

Quick Summary

• Difficulty: Expert
• Origin & Habitat: Only known from Buea, Cameroon (near Mount Cameroon in West Africa). The region is tropical rainforest with high humidity and warm temperatures year-round ^[1].
• Colony Type: Unknown, only a single queen has ever been collected, colony structure is entirely undocumented.
• Size & Growth:
  • Queen: Size data unavailable (only head measurements exist, total body length not recorded) ^[1].
  • Worker: Unknown, workers have never been collected or described.
  • Colony: Unknown, no colony has ever been observed.
  • Growth: Unknown
  • Development: Unknown, no data on development exists. (No worker caste has ever been described for this species.)
• Antkeeping:
  • Temperature: No data exists. Based on the tropical rainforest origin, a warm range of 24-28°C is a plausible guess, but unconfirmed.
  • Humidity: No data exists. Based on the rainforest habitat, high humidity (70-80%) is a plausible guess, but unconfirmed.
  • Diapause: Unknown, tropical species may not require a formal diapause, but no seasonal data is available.
  • Nesting: Unknown, no natural nesting site has ever been recorded.
• Behavior: Completely undocumented. No observations of temperament, foraging, or defense exist for this species.
• Common Issues: Known from a single specimen collected in 1937, no living colony or captive breeding has ever been documented., No workers have ever been described, making any captive attempt entirely speculative., All care recommendations are pure guesses based on related species, with no species‑specific validation., Wild‑caught queens (if ever found) may carry parasites or diseases with no known treatment protocols., Extreme difficulty due to complete absence of husbandry information and practically zero availability in the hobby.

Species Overview and Identification

Simopone matthiasi is one of the most poorly known ant species worldwide, represented solely by a dealate (wingless) queen collected in Buea, Cameroon on March 6,1937. The specimen was found in the collector's clothing ^[1]. The queen has a uniform light brown coloration, its total body length has not been recorded, but morphological measurements of the head and other body parts are published in the taxonomic description (Bolton & Fisher,2012). No workers, males, or colonies have ever been documented, and the species has not been seen since the original collection.

Taxonomy and Classification

Simopone matthiasi belongs to the subfamily Dorylinae (army ants), but unlike typical army ant genera such as Dorylus or Eciton, Simopone species are cryptic predators that do not form massive swarm raids. The genus contains about 30 described species, all rarely encountered. This species was originally described by Kutter in 1977 and redescribed by Bolton and Fisher in 2012,who provided all known morphological data ^[1]. It is placed in the emeryi species group, diagnosed by features of the clypeus and pygidial fork.

Known Distribution

The only record is from Buea, Cameroon, on the slopes of Mount Cameroon in West Africa. This area lies within the Guinean forest zone, with tropical rainforest climate, high humidity, and abundant rainfall throughout the year. The exact nesting location of the holotype queen is unknown, she was found on the collector's clothing rather than at a nest site ^[1]. No additional specimens or observations have been reported anywhere else.

Husbandry Challenges

Simopone matthiasi presents extreme difficulties for antkeepers. The species has never been kept in captivity, no living colony has ever been observed, and nothing is known about its diet, founding method, growth, or basic biology. The only specimen is the original queen collected 87 years ago. Any attempt to keep this species would be entirely experimental, with no established protocols. Furthermore, since no wild colonies have ever been found besides the type specimen, acquiring a colony is essentially impossible. This species is best regarded as a subject for taxonomic research, not captive husbandry. ^[1]
