Paraparatrechina neela

Quick Summary

• Difficulty: Expert
• Origin & Habitat: Only known from Yingku Village, East Siang District, Arunachal Pradesh, India (28.4606°N,94.8841°E) at 803 m elevation in secondary forest ^[1]. The region has a tropical humid-subtropical climate with temperatures of 18-28°C and high annual rainfall of 4168 mm ^[2].
• Colony Type: Unknown, colony structure has not been documented ^[1].
• Size & Growth:
  • Queen: Unknown, no queen specimens described ^[1]
  • Worker: 1.69-1.76 mm total length ^[1]
  • Colony: Unknown, only two workers collected ^[1]
  • Growth: Unknown
  • Development: Unknown, no captive studies ^[1] (No development data exists)
• Antkeeping:
  • Temperature: Based on type locality climate (18-28°C), aim for roughly 22-26°C ^[2].
  • Humidity: Keep substrate consistently moist but not waterlogged, based on high rainfall ^[2].
  • Diapause: Unknown, no data on diapause behavior ^[1].
  • Nesting: In nature, found in tree hollows, in captivity, use small test tube setup or narrow-chambered nest ^[1].
• Behavior: Behavior is unstudied. Based on genus, likely shy. Escape prevention is critical due to tiny size ^[1].
• Common Issues: this species has never been kept in captivity, no established care protocol, extremely limited distribution makes wild colonies impossible to obtain, tiny size makes escape prevention challenging and critical, no information on diet acceptance, feeding requires experimentation, basic biology like colony structure remains unknown

Discovery and Rarity

Paraparatrechina neela was described in 2024 and is known from only two worker specimens collected in May 2022 from a single location in the Eastern Himalayas ^[1]. This makes it one of the rarest ant species, with no biological context beyond the initial discovery. The species is found in Yingku Village, Arunachal Pradesh, a region with tropical to subtropical climate ^[1].

It is the second Paraparatrechina species documented from the Indian subcontinent, distinguished by its metallic blue coloration, which led to the name 'neela' meaning blue in Indian languages ^[1]. For antkeepers, this species offers a chance to contribute to scientific knowledge through captive care experiments.

Natural Habitat and Climate

The type locality is at 803 m elevation in a secondary forest, with ants collected from debris in a tree hollow 3 m above ground ^[1]. The climate has high rainfall (4168 mm annually) and temperatures of 18-28°C ^[2].

For captivity, maintain consistent moisture without waterlogging, with temperatures in the low-to-mid 20s Celsius. The tree-hole nesting suggests preference for enclosed, humid spaces ^[1].

Appearance and Identification

Workers are 1.69-1.76 mm total length with an opaque metallic blue body, except for brown antennae, mandibles, and legs ^[1]. The head is subtriangular, about 1.2 times longer than wide, with 12-segmented antennae ^[1]. The mandible has 5 teeth, and the propodeum has a short angular dorsal face ^[1].

The blue coloration is unique to this species, making identification straightforward once observed.

Feeding and Nutrition

No specific dietary data exists. Based on related Formicinae ants, they likely consume small insects for protein and sugar sources like honeydew or diluted honey ^[2]. Prey should be tiny, such as springtails or fruit fly larvae, due to their small size. Feeding is experimental, with small portions to avoid mold.

Housing and Setup

In nature, they nest in tree cavities, in captivity, start with a small test tube setup with tight cotton plugs to prevent escapes ^[1]. As colonies grow, use small nests with narrow chambers scaled to their size, ensuring humidity retention and ventilation. Escape prevention is critical due to their tiny size.

Challenges and Considerations

This species has never been kept in captivity, so care is experimental. Obtaining specimens is difficult, as only two workers are known. Basic biology like colony structure is unknown, making it suitable only for expert keepers willing to pioneer care. ^[1]
