Oravelia
Drake & Chapman, 1963
Species Guides
1Oravelia is a of minute semiaquatic true bugs in the Macroveliidae, established by Drake & Chapman in 1963. Members of this genus belong to the infraorder Dipsocoromorpha, a group of small predatory heteropterans often associated with moist . The genus is poorly documented in scientific literature, with only two observations recorded on iNaturalist as of the available data.

Identification
Oravelia can be distinguished from other macroveliid by genitalic characters, particularly male paramere structure. The genus is characterized by small body size (typical for Dipsocoromorpha, generally under 5 mm), with the general habitus of Macroveliidae including an elongate body form and relatively long . Definitive identification to species level requires microscopic examination of genitalia.

Habitat
Members of Macroveliidae, including Oravelia, are semiaquatic and typically inhabit moist terrestrial environments adjacent to water bodies such as stream margins, seeps, and wet meadows. They are often found in saturated soil, moss, or among vegetation in humid microhabitats.
Distribution
The precise geographic distribution of Oravelia is poorly documented due to limited sampling and taxonomic study. The Macroveliidae has representatives in North America, Central America, and parts of the Neotropics; Oravelia appears to be known from limited localities with insufficient published range data.
Ecological Role
As members of Dipsocoromorpha, Oravelia likely function as micro- in moist soil and litter , contributing to regulation of small in semiaquatic microhabitats.
Human Relevance
No direct human relevance has been documented. The has no known economic importance in agriculture, forestry, or public health.

More Details
Taxonomic obscurity
Oravelia remains one of the least documented within Macroveliidae, with minimal published descriptions and no comprehensive revision available. The original description by Drake & Chapman (1963) established the genus based on limited material, and subsequent taxonomic work has been sparse.
Collection challenges
Specimens of Oravelia and other Dipsocoromorpha are rarely collected due to their minute size, cryptic habits in saturated substrates, and the specialized collecting techniques required (e.g., Berlese extraction of wet litter, splashing water onto banks to flush specimens).
