Hypoponera shattucki

Quick Summary

• Difficulty: Unknown, this is a newly described species with no established husbandry records
• Origin & Habitat: Endemic to India, found in Arunachal Pradesh (2800m) and Kerala (1003m) ^[1][2]. The Kerala population at Periyar Tiger Reserve indicates tropical forest habitat, while the Himalayan collection at Lumla suggests cooler conditions at altitude. Workers were collected under stones in shaded areas ^[1].
• Colony Type: Colony structure is unconfirmed, no data exists on queen number or colony size in the wild
• Size & Growth:
  • Queen: Not described, only workers have been documented ^[1]
  • Worker: Total length data unavailable, estimated ~2-3mm based on genus Hypoponera ^[1]
  • Colony: Unknown, only 4 workers have ever been collected ^[1]
  • Growth: Unknown
  • Development: Unknown, no development data exists for this species (Based on related Hypoponera species, expect development of several months under optimal conditions)
• Antkeeping:
  • Temperature: Likely adaptable given the elevation range (1000-2800m) ^[1]. Start around 22-26°C and observe colony activity. The Kerala population suggests tolerance for warm, humid tropical conditions.
  • Humidity: Appears to prefer damp, shaded microhabitats, workers were found under stones in shady locations ^[1]. Keep nest substrate consistently moist but not waterlogged.
  • Diapause: Unknown, no data on overwintering requirements. The high-altitude Arunachal population may experience cooler conditions than the Kerala population.
  • Nesting: In the wild, they nest under stones in shaded areas ^[1]. A naturalistic setup with moist substrate or a plaster or Y-tong nest with small chambers would likely work. Their tiny size requires tight chambers and excellent escape prevention.
• Behavior: Behavior is unstudied. Based on genus patterns, Hypoponera are typically cryptic, slow-moving ants that nest in soil or under stones. Their relatively prominent eyes compared to other Hypoponera may indicate more visual orientation. Escape prevention is critical due to their very small size, they can squeeze through standard test tube barriers. As a ponerine, they have a functional sting, but it is likely too small to affect humans.
• Common Issues: this species has never been kept in captivity, no husbandry information exists, tiny size means escapes are likely without fine mesh barriers, the species may be difficult to locate in the wild given its rarity, no information on acceptable food sources, colony founding behavior is completely unknown

Why This Species Is Special

Hypoponera shattucki is one of over 900 described species in the genus Hypoponera, but it stands out for having relatively prominent eyes, most Hypoponera species have reduced or completely absent eyes ^[1]. This makes it particularly interesting for antkeepers who enjoy observing unusual morphological traits. The species was only described in 2015,making it one of the newer additions to the antkeeping hobby's potential species list ^[1]. Its rarity in collections (only 4 workers ever collected) means that successfully maintaining a colony would be a significant achievement and could contribute to our understanding of this poorly known species.

Natural History and Distribution

This species is endemic to India, known from just two widely separated locations: Arunachal Pradesh in the northeastern Himalayas at 2800m elevation, and Kerala in the southern Western Ghats at around 1000m ^[1][2]. This unusual distribution spanning both high-altitude Himalayan and tropical forest habitats suggests the species may have some flexibility in its environmental requirements. All specimens have been collected in October, either by hand under stones or via Winkler sampling (a method for extracting small invertebrates from leaf litter and soil) ^[1]. The type locality in Kerala is in a protected area (Periyar Tiger Reserve), indicating preference for natural forested habitats.

Housing and Nesting

Based on collection data, these ants prefer shaded, damp microhabitats under stones ^[1]. For captivity, a naturalistic setup with a layer of moist soil or a small plaster or Y-tong nest with tight chambers would be appropriate. The chambers should be scaled to their tiny size, workers are only about 2-3mm long. Excellent escape prevention is essential because their small size allows them to squeeze through gaps that would hold larger ants. Use fine mesh on any ventilation holes and ensure all connections are sealed. A small outworld with a water moat or barrier tape can help contain foragers.

Feeding and Diet

The diet of Hypoponera shattucki has not been studied. Most Hypoponera species are generalist predators and scavengers, feeding on small invertebrates and likely tending aphids for honeydew ^[3]. Given their tiny size, they would need very small prey items, springtails, booklice, or small fruit fly pieces would be appropriate starting points. Sugar sources may be accepted, but start with protein offerings and observe. Because nothing is known about their specific dietary preferences, offer a variety and note what gets consumed.

Temperature and Seasonal Care

The wide elevation range (1000-2800m) where this species has been found suggests some temperature flexibility ^[1]. The Kerala population lives in a tropical climate, while the Arunachal population experiences much cooler conditions at altitude. Start around 22-26°C and monitor colony behavior, if workers become sluggish, slightly warmer conditions may help, if they avoid heated areas, reduce temperature. No data exists on diapause requirements. Given the Himalayan collection location, a cool period during winter months may be beneficial, but this is speculative.
