forcepstails, japygids
Genus Guides
2is a of hexapods in the order Diplura, commonly known as forcepstails or japygids. The family is distinguished by unsegmented, hardened, pincer-like at the tip, which function in prey capture. It comprises approximately 70 arranged in seven . Japygidae belongs to the superfamily and is sister to Evalljapygidae based on mitochondrial phylogenomic analysis.

Identification
Look for hardened, pincer-like (chelate) that are unsegmented, distinguishing from other dipluran . The cerci are used actively to grasp prey. Body form is generally more robust than the thread-like cerci of Campodeidae (bristletails).
Habitat
Soil ; specific microhabitat preferences within soil profiles are not well documented for the as a whole.
Distribution
Global distribution in soil ; present across multiple continents though specific range boundaries are poorly documented for most .
Diet
Predatory on tiny soil-dwelling prey; are used to catch prey items.
Life Cycle
Undergoes continuous molting and growth throughout lifespan, as characteristic of Diplura generally; specific developmental stages for are not separately documented.
Behavior
Uses pincer-like to actively capture prey.
Ecological Role
Soil-dwelling ; specific functions are not well documented for this .
Human Relevance
No documented direct interactions with humans; occasionally encountered in soil and ecological studies.
Similar Taxa
- HeterojapygidaeAlso possesses forceps-like and belongs to ; distinguished by phylogenetic position and likely morphological differences in cercal structure, though specific diagnostic characters require examination.
- EvalljapygidaeSister to within ; morphological distinctions require detailed examination of cercal and genital characters.
- CampodeidaeOther major dipluran ; distinguished by long, thread-like, segmented rather than hardened pincer-like cerci.
- Forficulidae (earwigs)Convergent similarity in pincer-like ; distinguished by presence of wings (when present), different body plan, and unrelated phylogenetic position within Dermaptera rather than Diplura.
More Details
Phylogenetic position
Mitochondrial analysis places as sister to Evalljapygidae, with as sister to the combined Japygidae + Evalljapygidae clade within . This indicates Japygidae diverged later than Parajapygidae and Heterojapygidae.
Fossil record
