Gobryidae

Definition

A monotypic family of true flies (Diptera) containing the single genus Gobrya. These relatively rare flies are distributed across Southeast Asia, Taiwan, Indonesia, Malaysia, the Philippines, and New Guinea. Adults are often metallic in coloration and possess characteristically broad heads that exceed the width of the thorax and abdomen. The family was elevated from genus rank by McAlpine (1997); larval biology remains poorly known, and phylogenetic placement within the Brachycera requires further study.

Etymology

From the type genus Gobrya (Greek: possibly 'small treasure' or 'trifle') + -idae, the standard family suffix in zoological nomenclature.

Example

Specimens of Gobrya from New Guinea display the family's diagnostic metallic green coloration and disproportionately wide heads, but attempts to rear larvae from associated forest litter have failed to reveal their feeding habits or developmental substrate.

Synonyms

• Gobryinae (former subfamily rank)

Related Terms

• Diptera
• Brachycera
• monotypic family
• Gobrya
• McAlpine
• metallic coloration
• Southeast Asian fauna

Usage Notes

Formerly treated as a subfamily within another diptean group; current family status reflects McAlpine's 1997 revision. The combination of metallic integument and extreme head width distinguishes adults from similarly colored Chloropidae or other small flies in Malaise trap samples. Because larvae are unknown, Gobryidae is frequently omitted from larval keys and ecological syntheses of Oriental Diptera.
