Oxyopomyrmex pygmalioni

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Endemic to Cyprus, found on grassy coastal terraces of cliffs in Paphos district ^[1][2].
• Colony Type: Unknown, only worker caste has been described ^[1].
• Size & Growth:
  • Queen: size data unavailable
  • Worker: 0.48 mm (total length) ^[1]
  • Colony: Unknown, no colony size data available
  • Growth: Unknown
  • Development: Unknown, no direct data. Based on typical small Myrmicinae patterns, estimate 6-10 weeks at optimal temperature ^[3]. (Development timeline is unconfirmed. Temperature affects development speed.)
• Antkeeping:
  • Temperature: Keep at cool room temperature, around 18-24°C. Wild specimens were active at 16°C ^[1]. Avoid overheating.
  • Humidity: Moderate humidity. Found in grassy coastal terraces, so keep nest substrate consistently moist but not waterlogged ^[1].
  • Diapause: Likely yes, as a Mediterranean species, but unconfirmed ^[1].
  • Nesting: Natural nesting in soil under grass clumps. In captivity, use test tube setups or small formicaria with sandy/soil substrate ^[1].
• Behavior: Workers are docile and slow-moving, as they were hand-collected without defensive behavior ^[1]. Their tiny size means escape prevention is critical. They are active foragers even at cool temperatures.
• Common Issues: escape risk due to tiny size, use fine mesh barriers, overheating risk since they prefer cool conditions, colony founding uncertain as queen caste is unknown

Discovery and Taxonomy

Oxyopomyrmex pygmalioni was described in 2015 by Sebastian Salata and Lech Borowiec ^[1]. The species was discovered in Cyprus, specifically at Cape Drepano in the Paphos district ^[1]. The name honors Pygmalion, a figure from Greek mythology, reflecting the ant's sculptured appearance ^[1]. Only the worker caste has been described, so queen and male biology are unknown ^[1].

Natural Habitat and Distribution

This species is endemic to Cyprus, found only on grassy coastal terraces of cliffs in the Paphos district ^[1][2]. Workers were active at 16°C in windy conditions, indicating adaptation to cool, exposed environments ^[1]. The biogeographic region is Palearctic ^[2].

Identification and Appearance

Workers are tiny, with a total length of about 0.48 mm ^[1]. They are black with brownish accents on antennae and legs ^[1]. The head has longitudinal striae, and the pronotum is rugose ^[1]. These features distinguish it from related species.

Temperature and Cold Tolerance

Workers are active at 16°C in windy conditions, showing cold tolerance ^[1]. For captivity, keep at cool room temperature (18-24°C) and avoid overheating ^[1]. This suggests they prefer cooler conditions than most ants.

Related Species and Care Inferences

Oxyopomyrmex belongs to the tribe Stenammini, which includes genera like Messor and Pheidole ^[1]. Diet is unconfirmed for this species, but based on tribe patterns, they may be omnivorous ^[3]. Nesting in soil under grass clumps is inferred from habitat ^[1]. Care should start with standard test tube setups and adjust based on colony behavior.
