Phytoliriomyza

Hendel, 1931

Phytoliriomyza is a of leaf-mining in the , established by Hendel in 1931. The genus contains at least 20 described distributed across multiple continents. Members are specialized whose feed internally within 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.

Habitat

are determined by 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

are that feed internally on 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 into leaf tissue. feed as internal , creating visible mines within leaves. The mining produces characteristic patterns visible on the leaf surface.

Ecological Role

As , contribute to pressure on plants. The specialized host associations suggest potential role in regulating host 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 outside the period.
