Chirosia spinosissima
(Malloch, 1919)
Chirosia spinosissima is a of root-maggot fly in the Anthomyiidae, described by Malloch in 1919. Members of this are generally associated with ferns, with larvae typically developing in decaying fronds or rhizomes. The specific epithet 'spinosissima' suggests a heavily spined , likely referring to distinctive bristle arrangements on the body. As with many anthomyiid species, detailed biological information remains limited in published literature.

Identification
The name 'spinosissima' (Latin: 'most spiny') indicates exceptionally dense or prominent bristling compared to . In Chirosia, key diagnostic features include chaetotaxy patterns on the and legs. Definitive identification requires examination of male terminalia; the surstyli and structure distinguishes species within the . Females may be difficult to separate from related species without associated biological or distributional data.
Distribution
Original description based on specimens from Scotland. Records in GBIF indicate occurrence in the United Kingdom, with potential broader distribution in northern Europe consistent with temperate anthomyiid ranges. Precise distribution limits remain poorly documented.
