Species Guides

5

Phytoliriomyza is a of leaf-mining flies in the Agromyzidae, established by Hendel in 1931. The genus contains at least 20 described distributed across multiple continents. Members are specialized leaf miners whose larvae feed internally within plant leaf tissue. Some species show strong associations with particular plant groups, including ferns and Jacaranda. The genus has been documented from Brazil, North America, Europe, Africa, South America, and Oceania.

Identification

Identification to level requires examination of terminalia and detailed morphological features. Brazilian species can be distinguished using the key provided by Eiseman et al. (2026), which utilizes characters of the male genitalia and external . The is placed in Phytomyzinae based on phylogenetic and morphological criteria.

Habitat

are determined by plant distribution. have been documented in mesic forests, dry-mesic deciduous upland forests, and areas supporting fern on north-facing slopes and dolomite bluffs. The specific microhabitat is the interior of host plant leaves where larval mining occurs.

Distribution

Documented from North America (USA, including Vermont and California), South America (Brazil, Argentina), Europe (Italy, Sicily), Africa (South Africa), and Oceania (Australia and New Zealand). Scandinavian records exist from Denmark, Norway, and Sweden.

Diet

Larvae are leaf miners that feed internally on plant leaf tissue. Specific plants vary by : Phytoliriomyza felti has been observed on ferns including Pellaea atropurpurea and Asplenium species; Phytoliriomyza jacarandae is associated with Jacaranda mimosifolia.

Host Associations

  • Pellaea atropurpurea - leaf mines documented
  • Asplenium - leaf mines documented on multiple
  • Jacaranda mimosifolia - for P. jacarandae

Behavior

females deposit into plant leaf tissue. Larvae feed as internal leaf miners, creating visible mines within leaves. The mining produces characteristic patterns visible on the leaf surface.

Ecological Role

As leaf miners, larvae contribute to herbivory pressure on plants. The specialized host associations suggest potential role in regulating host plant or serving as food source for .

Taxonomic history

The was established by Hendel in 1931. Brazilian fauna remained poorly known until 2026, when six new were described and two new records reported, more than doubling the known Brazilian diversity.

Observation notes

Leaf mines of Phytoliriomyza felti are visible as pale trails within fern fronds and can persist on herbarium specimens and winter foliage, allowing detection outside the period.
