Identification
in Oligacanthopus possess the diagnostic features of Mogoplistidae: small body size and a dense covering of on the body and wings, giving a scaly or -like appearance. The name refers to reduced spination on the hind legs compared to related genera. Specific identification requires examination of male genitalia and detailed leg spine counts.
Habitat
Members of this inhabit moist, sheltered microhabitats including leaf litter, decaying vegetation, and under bark or stones. These environments provide the humidity necessary for maintenance and protection from desiccation.
Distribution
Florida, United States. Distribution is poorly documented due to limited sampling effort and the cryptic habits of these insects.
Behavior
Scaly crickets in this are cryptic and secretive, remaining concealed in leaf litter and debris during daylight hours. They are likely foragers, though specific behavioral observations for Oligacanthopus are limited.
Ecological Role
As decomposers and , members of this contribute to nutrient cycling in leaf litter . They serve as prey for small and vertebrates in forest floor .
Human Relevance
No direct economic or medical significance. The is of interest to orthopterists and biodiversity researchers documenting North American fauna.

Taxonomic history
Oligacanthopus was established by Rehn & Hebard in 1912 based on specimens from Florida. The has received limited taxonomic attention since its description, and the number of included remains uncertain. The name refers to the reduced (oligo-) number of spines (-acantho-) on the foot (-pus), a diagnostic character separating it from related genera.
