Helina rufitibia
(Stein, 1898)
Helina rufitibia is a of muscid fly in the Phaoniinae, originally described as Aricia rufitibia by Stein in 1898. The species epithet refers to the reddish coloration of the tibiae. Like other Helina species, it belongs to a diverse of small to medium-sized flies commonly found in various terrestrial . The species has been documented through limited observations, with 7 records on iNaturalist suggesting it is either rare or underreported.

Accurate determination requires comparison with other Helina species and examination of genitalic structures typical for the . Specimens should be compared with original description or verified reference material.

Habitat
Terrestrial typical for Phaoniinae muscid flies; specific microhabitat preferences unknown.
Distribution
Original description by Stein (1898); specific geographic range not well documented in available sources. Observations on iNaturalist suggest presence in Europe, but precise distribution requires further verification.
Seasonality
Activity period not documented in available sources.
Life Cycle
Larval development presumably in decaying organic matter or soil, as typical for Muscidae, but specific details unknown.
Behavior
not documented; presumably activity typical for muscid flies.
Ecological Role
Presumed or microbe-feeder in larval stages, contributing to nutrient cycling; specific ecological function not documented.
Human Relevance
No documented economic or medical significance.
Similar Taxa
- Helina species share general body plan and require careful examination of leg coloration, thoracic chaetotaxy, and male genitalia for separation.
- Other Phaoniinae genera members share similar habitus; -level characters including hypopygial structure and leg features distinguish Helina.

Nomenclatural history
Originally described in Aricia as Aricia rufitibia Stein, 1898; later transferred to Helina.
Data deficiency
Very limited published information available; most aspects of require original research. The low number of iNaturalist observations (7) suggests either genuine rarity or identification challenges leading to underreporting.
