Parasyscia dohertyi

Quick Summary

• Difficulty: Hard
• Origin & Habitat: Tropical Southeast Asia, including Borneo, Indonesia (Kalimantan, Sumatra), Malaysia, Singapore, Thailand, and Vietnam. Inhabits forest environments in the Indomalaya region ^[2][3].
• Colony Type: Based on Dorylinae patterns, likely monogyne (single queen), but specific data for this species is unconfirmed.
• Size & Growth:
  • Queen: Size data unavailable, no total length measurements in available literature
  • Worker: Size data unavailable, no total length measurements in available literature
  • Colony: Unknown, no documented colony sizes
  • Growth: Unknown
  • Development: Estimated 6-8 weeks based on typical Dorylinae development patterns at tropical temperatures (Development timeline is inferred from related Dorylinae species, no specific study exists for this species)
• Antkeeping:
  • Temperature: Keep warm and stable, roughly 24-28°C, based on tropical forest origin. A gentle gradient allows workers to self-regulate.
  • Humidity: Keep the nest substrate consistently moist but not waterlogged, as this species inhabits humid forest environments.
  • Diapause: No diapause likely required due to tropical distribution. A brief cool period may benefit colony health in temperate climates.
  • Nesting: Use a naturalistic setup with moist substrate or a Y-tong/plaster nest. They likely prefer dark, humid nest chambers typical of Dorylinae species.
• Behavior: Behavior is not well documented. Based on Dorylinae patterns, they are predatory on small invertebrates and may exhibit raiding behaviors, but are generally less aggressive than true army ants. Their small size suggests secretive nesting, and escape prevention should be moderate due to their size.
• Common Issues: limited biological data makes proper care challenging, much is inferred from genus patterns, colony size in captivity is unknown, making growth expectations uncertain, predatory diet requirements may be difficult to meet with appropriate live prey, humidity control is critical, too dry causes colony decline, wild-caught colonies may carry parasites that are poorly understood

Distribution and Natural Habitat

Parasyscia dohertyi is found throughout the Indomalaya region, with documented records from Borneo, Indonesia (Sumatra), Malaysia, Singapore, Thailand, and Vietnam ^[2][3]. The species was originally described from Pulo Laut, Kalimantan ^[2]. It inhabits tropical forest environments, typically nesting in soil, rotting wood, or under stones in shaded areas ^[2].

Taxonomy and Classification

Parasyscia dohertyi was originally described as Parasyscia dohertyi by Emery in 1902 and transferred to Parasyscia by Borowiec in 2016 ^[2]. It belongs to the subfamily Dorylinae and is part of the Old World Sphinctomyrmex/Eusphinctus clade ^[1]. The species was previously known as Parasyscia dohertyi, a synonym established by Wilson in 1959 ^[2].

Predatory Behavior and Diet

As a Dorylinae ant, Parasyscia dohertyi is predatory on small invertebrates like insects and springtails. In captivity, offer small live prey such as fruit flies or pinhead crickets, sized appropriately for the ants. Sugar sources are not a major part of their diet, but they may occasionally accept honeydew ^[2].

Housing and Nesting

Use a Y-tong or plaster nest with moist substrate to mimic their natural humid forest habitat. Provide an outworld for foraging with easy food access. Escape prevention is important due to their small size, but they are not strong climbers ^[2].

Temperature and Seasonal Care

Maintain temperatures around 24-28°C, consistent with their tropical origin. A slight gradient allows self-regulation. Diapause is not required, but a brief cool period in winter may benefit colonies in temperate climates ^[2].
