Perissomyrmex medogensis

Quick Summary

• Difficulty: Expert
• Origin & Habitat: Tibet, China, Medog County at 2750 m elevation in Abies forest on the south slope of the Himalaya Mountains ^[1]. Nests inside decayed wood in ground samples ^[1].
• Colony Type: Monogynous with single queen colonies ^[1].
• Size & Growth:
  • Queen: 5.0 mm ^[1]
  • Worker: 3.9-4.1 mm ^[1]
  • Colony: Up to 70 individuals ^[1]
  • Growth: Unknown
  • Development: Unknown, no development data available ^[1] (No species-specific data on development timeline)
• Antkeeping:
  • Temperature: Based on high-altitude origin, likely prefers cool conditions around 18-22°C ^[1].
  • Humidity: Provide moderate humidity with a moist nest substrate, based on nesting in decayed wood ^[1].
  • Diapause: Unknown, but likely requires winter diapause due to temperate origin ^[1].
  • Nesting: Nests in decayed wood in wild, so wood-based or plaster nests with wood inclusions are suitable ^[1].
• Behavior: Workers are weakly dimorphic and possibly forage on the ground ^[1]. Based on their subfamily (Myrmicinae) and tribe (Crematogastrini), they likely use a smear defense mechanism. Escape risk is moderate due to small size.
• Common Issues: lack of species-specific care data could lead to improper husbandry., diet preferences are unknown, risking starvation., temperature and humidity requirements are unclear., hibernation needs are undocumented., colony failure risk due to limited knowledge., rare in hobby, difficult to acquire.

Discovery and Distribution

Perissomyrmex medogensis was described in 2012 by Xu and Zhang. It is known only from Medog County, Tibet, China, at about 2750 m elevation in Abies forest ^[1]. The species nests inside decayed wood in ground samples ^[1].

Appearance and Identification

Workers are 3.9-4.1 mm long with a nearly square head and short propodeal spines ^[1]. The body is black with brownish mandibles, antennae, and legs ^[1]. Soldiers are larger at 4.4-4.8 mm with proportionally bigger heads ^[1].

Colony Structure

Colonies are monogynous with a single queen ^[1]. A small soldier caste makes up about 6.5% of the colony ^[1]. Workers are weakly dimorphic ^[1].

Housing and Nesting

In the wild, these ants nest in decayed wood ^[1]. For captivity, wood-based or plaster nests with wood inclusions are suitable ^[1]. Maintain moderate humidity and provide escape prevention for small ants.

Feeding and Diet

Diet preferences have not been studied for this species ^[1]. As Myrmicine ants, they may accept typical ant foods, but specific acceptance is unknown.

Temperature and Seasonal Care

No specific temperature requirements are documented, but high-altitude origin suggests cool conditions around 18-22°C ^[1]. Diapause is likely but undocumented ^[1].
