Hesperoconopa
Alexander, 1948
Hesperoconopa is a of crane flies in the Limoniidae, first described by Charles Paul Alexander in 1948. The genus contains eight recognized distributed across three disjunct regions: North America, India, and the Russian Far East. Members belong to the Chioneinae, a diverse group of small to medium-sized crane flies. The genus name derives from Greek roots, with 'hespero-' referring to the west and 'conopa' relating to crane flies.

Identification
Hesperoconopa can be distinguished from other Chioneinae by genitalic characters, particularly the structure of the male terminalia. The type species H. aperta and related species show distinctive features in the gonostylus and paramere . Species-level identification requires examination of male genitalia, with H. acutistyla named for its sharply pointed styli and H. dolichophallus characterized by elongated phallic structures.
Distribution
North America (western and northern regions), India (Sikkim and adjacent Himalayan areas), and the Russian Far East (Siberian and Pacific coastal regions). The disjunct distribution pattern suggests possible relictual ranges or incomplete sampling across intervening regions.

Etymology
The name combines 'Hespero-' (Greek: evening, western) with '-conopa', a common suffix in Limoniidae genus names derived from 'konops' (Greek: gnat or mosquito). The name likely references the western (North American) distribution of the type .
Taxonomic history
Several were transferred into Hesperoconopa from other upon its establishment. H. aperta was originally described as Limonia aperta by Coquillett in 1905, and H. melanderi, H. pilipennis, and H. pugilis were previously placed in allied genera before Alexander's 1948 revision.
