Clinodiplosis is a of gall midges (Cecidomyiidae, Diptera) established by Kieffer in 1894. in this genus are gall inducers that form stem galls on plants across multiple including Asteraceae, Myrtaceae, and Urticaceae. The genus has been documented in Brazil and has distribution records in Denmark, Norway, Sweden, and the United States (Vermont).

Identification

-level identification requires examination of morphological characters including tarsal claw structure, male genitalia ( lobing, gonostylus proportions, shape), and female reproductive structures. -level identification depends on plant association and detailed measurements of genitalia and body proportions.

Habitat

Diverse environments including Amazon Rainforest, shaded and newly cultivated areas, dry or humid high areas, road margins, and crops. Associated with both sun-exposed and shaded conditions depending on plant requirements.

Distribution

Documented from Brazil (Minas Gerais, Rondônia states) with additional records from Denmark, Norway, Sweden, and Vermont, United States.

Seasonality

synchronized with plant , particularly leaf sprouting peaks at the beginning of rainy seasons. Gall duration varies by light availability, lasting approximately two months longer on sun-exposed plants compared to shaded plants.

Host Associations

Ageratum conyzoides - Gall inducerInduces spherical green stem galls with white trichomes; first record of Clinodiplosis on Ageratum
Eugenia uniflora - Gall inducerGall development synchronized with leaf sprouting peaks; galls last longer on sun-exposed plants
Cecropia sp. - Gall inducerInduces globoid stem galls; first Clinodiplosis recorded on Urticaceae

Life Cycle

Development occurs inside stem galls. Larvae are and cylindrical. are small (1.50–1.80 mm body length). timing is phenologically synchronized with plant leaf sprouting, with young and mature galls developing at peak sprouting periods.

Behavior

Induces stem galls that modify plant tissue. Gall chambers may contain more than one larva. Shows phenological plasticity, adjusting timing in response to host plant phenological variations and such as light availability.

Ecological Role

Gall inducer that forms plant neoformations. Acts as a specialized causing plant tissue modification. Part of plant–gall inducer systems where environmental interactions affect dynamics.

Taxonomic history

established by Kieffer in 1894. Multiple new have been described from Brazil in recent years, expanding known plant associations across three plant .

Research significance

Studies of Clinodiplosis profusa have demonstrated how gall inducer adjust to phenological variations of plants in response to light availability, providing insights into plant–insect interaction dynamics.
