Pheidole neoschultzi

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Tropical rainforest of Guyana and French Guiana, collected from leaf litter at elevations from 60 to 732 meters ^[1][4]
• Colony Type: Colony structure is unconfirmed. No data on queen number or ergatoid reproductives.
• Size & Growth:
  • Queen: Size data unavailable, no queen caste has been described.
  • Worker: Major workers: ~1.8 mm total length, minor workers: ~1.2 mm total length ^[1]
  • Colony: Unknown, no data on colony size.
  • Growth: Unknown, no data on growth rate.
  • Development: Unconfirmed, no direct data. Based on typical Pheidole patterns, estimate 6-8 weeks at optimal temperatures. (Development timeline is unconfirmed, estimates are based on genus-level patterns.)
• Antkeeping:
  • Temperature: Keep at 24-27°C, inferred from tropical habitat ^[1]. A gentle temperature gradient is recommended.
  • Humidity: Keep substrate consistently moist but not waterlogged, as they live in leaf litter environments ^[1].
  • Diapause: No diapause required, tropical species ^[1].
  • Nesting: Use moist substrate or Y-tong/plaster nests with small chambers scaled to their tiny size. Based on related species, may benefit from decaying plant matter ^[1].
• Behavior: Behavior unstudied in captivity. Based on Pheidole genus patterns, expect moderate foraging activity. Escape risk is high due to tiny size ^[1].
• Common Issues: escape prevention is critical due to tiny size, high humidity can lead to mold if ventilation is poor, lack of biological data requires keeper experimentation, tiny size makes feeding difficult, wild-caught colonies may be hard to establish

Discovery and Naming

Pheidole neoschultzi has an unusual taxonomic history. It was first described in 2005 as Pheidole neoschultzi, named in honor of Ted R. Schultz ^[1]. However, the name was already occupied by Pheidole schultzei from 1910,making it a junior homonym ^[2][3]. In 2006,the replacement name neoschultzi was proposed ^[3]. The holotype specimen remains the same but now carries a label with the new name ^[2].

Identification and Distinguishing Features

Within the tachigaliae-group, P. neoschultzi can be confused only with Pheidole tachigaliae. The key difference is head shape: P. neoschultzi has a roughly heart-shaped head, while P. tachigaliae has a rectangular head ^[1]. P. neoschultzi is less hairy and lacks carinulae on the anterior pronotum ^[1]. Both species have 11-segmented antennae and longitudinal carinulae ^[1].

Natural History and Habitat

P. neoschultzi is collected from leaf litter using mini-Winkler bags, indicating a leaf-litter ant lifestyle ^[1]. Related species nest in plant material or soil, suggesting flexible nesting preferences ^[1]. The species is found at elevations from 60 to 732 meters in Guyana ^[1][4].

Housing and Setup

Given their tiny size and leaf-litter habitat, use a naturalistic setup with moist substrate or a Y-tong/plaster nest with small chambers ^[1]. Escape prevention is critical due to their minute size. Provide a water tube for drinking water.

Feeding and Diet

Pheidole species are generalist omnivores. Offer small protein sources like fruit flies and sugar sources like honey water. Food items must be appropriately sized for their tiny size.

Temperature and Seasonal Care

As a tropical species, maintain warm conditions at 24-27°C ^[1]. No diapause is needed. Seasonal variation in rainfall may affect activity, but consistent conditions are recommended in captivity.
