Dallasiellus discrepans
(Uhler, 1877)
Dallasiellus discrepans is a of burrowing bug in the Cydnidae, first described by Uhler in 1877. Members of this are characterized by their (burrowing) adaptations and association with soil . The species is documented from North America, though detailed biological studies remain limited. Like other cydnids, it likely possesses the family-typical scutellum and hemelytral structure of Pentatomomorpha.

Identification
Dallasiellus can be distinguished from other Cydnidae by genitalic characters and specific tarsal modifications. D. discrepans specifically may be separated from by subtle differences in the male paramere structure and pronotal shape, though definitive identification requires examination of genitalia. The genus Dallasiellus is generally smaller and more slender than the related genus Cydnus.
Habitat
As a member of Cydnidae, this is associated with soil and ground-level . Cydnids are burrowing bugs that inhabit loose soil, leaf litter, and root zones of plants. Specific microhabitat preferences for D. discrepans have not been documented.
Distribution
North America. Records indicate presence in the United States, though precise state-level distribution is poorly documented due to limited collection effort and identification challenges.
Behavior
Burrowing is characteristic of the Cydnidae, with using legs to dig in soil. Specific behavioral observations for D. discrepans have not been published.

Taxonomic history
Originally described as Sehirus discrepans by Uhler in 1877, later transferred to Dallasiellus. The Dallasiellus was established to accommodate with distinctive male genitalia and represents a relatively small lineage within Cydnidae.
Collection status
The is rarely encountered in collections, with only 5 observations documented on iNaturalist as of source data. This rarity likely reflects a combination of genuine scarcity, cryptic habits, and under-collection of soil-dwelling Heteroptera rather than actual rarity.
