Plutomurus wilkeyi
(K. Christiansen, 1964)
Plutomurus wilkeyi is a of (Collembola) in the Tomoceridae, first described by K. Christiansen in 1964. As a member of the Plutomurus, it belongs to a group of relatively large, robust springtails. The species is known from the Pacific North American region. Like other Tomoceridae, it possesses the (springing organ) characteristic of Collembola, though specific ecological details remain poorly documented.

Identification
Differentiation from other Plutomurus and Tomoceridae relies on microscopic examination of antennal segmentation, chaetotaxy, and genital structure. The species was described from Pacific North American material, and geographic origin may assist in narrowing identification possibilities. Confirmation requires comparison with or consultation of Christiansen's 1964 original description.

Appearance
As a member of Tomoceridae, Plutomurus wilkeyi likely exhibits the 's characteristic robust body form with well-developed . Tomocerid springtails generally have a cylindrical body shape, long , and often show pigmentation patterns. The Plutomurus is distinguished from related genera partly by antennal structure and chaetotaxy (bristle arrangement), though specific morphological details for P. wilkeyi require original description.
Distribution
Pacific North American region. Specific locality details are not available in the provided sources.
Ecological Role
As a soil-dwelling , likely contributes to decomposition processes and nutrient cycling in forest floor , though specific functional role has not been documented for this .

Taxonomic note
The Plutomurus was established to accommodate previously placed in Tomocerus that show distinct antennal and morphological characteristics. The specific epithet 'wilkeyi' honors an individual, likely a collector or colleague of the describer.
Data availability
Only 11 iNaturalist observations and limited literature references suggest this is rarely encountered or underreported. Original description in Christiansen 1964 remains primary source for identification.
