Leiobunum bimaculatum
Banks, 1893
Leiobunum bimaculatum is a of harvestman (order Opiliones) in the Sclerosomatidae, described by Nathan Banks in 1893. It belongs to the Leiobunum, a diverse group of long-legged harvestmen found primarily in North America. The species epithet 'bimaculatum' refers to two spots, suggesting a distinctive pattern. Like other members of its genus, it is a long-legged, soft-bodied arachnid with a body structure lacking the narrow waist seen in spiders.

Identification
Identification to level within Leiobunum is notoriously difficult and typically requires examination of male genitalia or detailed study of . The two spots referenced in the species name may aid in field recognition, but confirmation requires examination. Similar species include L. vittatum and L. crassipalpe, which share the long-legged morphology and woodland but differ in specific pattern elements and male secondary sexual characteristics.
Habitat
Wooded , consistent with the general of Leiobunum . Specific microhabitat preferences for this species are not documented.
Distribution
North America. Precise range boundaries within North America are not well documented in available sources.
Ecological Role
and scavenger, typical of harvestmen, feeding on small and organic detritus. Specific ecological studies for this are not available.
Human Relevance
No documented direct interactions with humans. Like other harvestmen, it is harmless to humans and may contribute to control of small pest in woodland environments.

Taxonomic Note
The Leiobunum is taxonomically challenging, with many difficult to distinguish without detailed morphological examination. The specific epithet 'bimaculatum' (Latin: 'two-spotted') suggests a diagnostic color pattern, but the original description and modern redescriptions should be consulted for definitive identification.
