Iralunelus politus
(Say, 1832)
Iralunelus politus is a of flat bug in the Aradidae, order Hemiptera. Originally described as Aneurus politus by Thomas Say in 1832, this species has been reclassified into the Iralunelus. Aradidae, commonly known as flat bugs or bark , are a family of true bugs characterized by their dorsoventrally flattened bodies adapted for living under bark and in other tight spaces. The family is primarily tropical in distribution, though some species extend into temperate regions of North America.

Identification
Identification to requires knowledge of Aradidae . The Iralunelus was established to accommodate species formerly placed in Aneurus. Distinguishing I. politus from and from species of related genera such as Aneurus requires examination of antennal segmentation, body proportions, and male genitalia. The original description by Say (1832) under Aneurus politus provides the primary reference for this species.
Habitat
Aradidae are typically found in association with dead or dying wood, under bark, in leaf litter, and in other decaying plant material. They occupy cryptic that provide protection and access to their fungal food sources. Specific habitat preferences for I. politus are not documented but likely follow the pattern.
Distribution
Records indicate presence in North America. The precise range within North America is not well defined in available sources, though the was described from material collected in the United States.
Diet
Aradidae feed primarily on fungi, particularly those associated with decaying wood and bark. They use their to extract nutrients from fungal . Specific dietary records for I. politus are not available.
Life Cycle
Behavior
Aradidae are cryptic insects that remain concealed under bark or in crevices during daylight hours. They are not known to be active dispersers, with limited capability in many . Behavioral observations specific to I. politus are not recorded.
Ecological Role
As fungivores, Aradidae contribute to nutrient cycling in forest by consuming fungi associated with wood decay. They form part of the of organisms that process dead plant material.
Human Relevance
Aradidae have minimal direct economic importance. They are not known as pests of crops or structures, nor are they considered beneficial in any commercial context. Their primary significance is ecological, as components of forest decomposer .
