Dolichopus albicoxa
Aldrich, 1893
Dolichopus albicoxa is a of long-legged fly in the Dolichopodidae, first described by Aldrich in 1893. As a member of the Dolichopus, it shares the family's characteristic elongated legs and predatory habits. The specific epithet 'albicoxa' refers to white (leg bases), a distinguishing morphological feature. Like other dolichopodids, this species is likely predatory on small insects, though specific behavioral and ecological details remain poorly documented.

Identification
Identification to level in Dolichopus generally requires examination of male genitalia, specifically the forward-protruding claspers and associated structures at the tip of the . The white referenced in the specific epithet may provide a useful visual cue for field recognition, though this has not been formally documented in accessible literature. Separation from other Dolichopus species relies on subtle morphological differences in genitalic structures and leg ornamentation.
Distribution
Documented from at least one observation; specific geographic range not well established in accessible sources. The Dolichopus is widespread across North America.
Diet
Likely predatory on small insects, consistent with -level characteristics of Dolichopodidae. possess modified lower lip structures () with opposable lobes for capturing and processing prey.
Life Cycle
Larval development presumed to be similar to other Dolichopus , likely in aquatic or semi-aquatic environments. Specific details unknown.
Behavior
Males of Dolichopus typically possess specialized on the front used in ; this trait likely applies to D. albicoxa but has not been specifically documented.
Ecological Role
of small insects; potential agent for pest insects such as mosquitoes.
Similar Taxa
- Other Dolichopus speciesConvergent , metallic coloration, and elongated legs; require genital examination for definitive separation.
- Condylostylus speciesSimilar size, metallic coloration, and use; Condylostylus typically has different leg proportions and lacks the specialized male tarsal ornamentation of Dolichopus.
- Hydrophorus speciesSimilar -level characteristics and predatory habits; Hydrophorus are more commonly associated with water surfaces and have different body proportions.

Taxonomic note
The is poorly represented in accessible literature and biodiversity databases, with minimal observation records available. Most biological inferences rely on - and -level characteristics.
Etymology
The specific epithet 'albicoxa' derives from Latin 'albus' (white) and '' (hip/leg base), referring to the white-colored coxae.
