Species Guides
1Cembrotia is a of gall midges in the Cecidomyiidae, described by Gagné in 2013. Members of this genus are small, delicate flies whose larvae induce gall formation on plants. The genus is relatively recently described and contains associated with conifers, particularly cedars (Cedrus spp.).

Identification
are minute flies (2–5 mm) with reduced wing venation characteristic of Cecidomyiidae: few crossveins, a simple R fork, and no . are long and bead-like with circumfilar loops ( of setae) on each flagellomere. The is distinguished from related cecidomyiid genera by larval gall on Cedrus and adult genitalic characters, particularly male terminalia structure.
Distribution
of Cembrotia have been documented in regions where Cedrus species occur naturally, including the Mediterranean basin (North Africa, Middle East) and Himalayan regions.
Host Associations
- Cedrus - gall inducerLarvae induce galls on cedar foliage or shoots
Ecological Role
As gall inducers on Cedrus, larvae manipulate plant tissue development, creating protected microhabitats that may also harbor and , thereby contributing to local complexity.
