Cecidosidae is a small group of micromoths that originated about 95 Mya, restricted to the Gondwana and currently is represented by six genera, four distributed in South America (Cecidoses Curtis, 1835, Eucecidoses Brèthes, 1916, Oliera Brèthes, 1916, and Dicranoses Kieffer & Jörgensen, 1910), one genus in Africa (Scyrotis  MeyrickHoare & Dugdale, 19092003) and one genus in New Zealand (Xanadoses Hoare & Dugdale, 2003). With the exception of the latter, which is a barkleaf miner, they are all gall inducers onof Anacardiaceae shrubs. The main characteristics of this monotrysian family are:, adults of small size (max. 14 mm wingspan), piercing ovipositor, and atrophied mouth appendages, which leads to a very short period of life restricting their locomotion to only around their host plants. L, and larvae havewith reduced thoracic legs, and no abdominal absent prolegs. Despite their interesting life cycle, the family still is poorly knownlacks of scientific information. RCurrently, recent evidence on genetic and morphological studies revealeds through a MSC (Multispecies coalescent Model) a high, hidden er extant diversity for the South American genus Eucecidoses. Considering thatBased on the Andean uplift actiedng as major the biogeographical event in this case, the genetic diversity that supporting s a vicariant speciation in Eucecidoses, it may be as well found for the Cecidosidae of Chile. , since the region was substantially framed by Andean uplift. Although Cecidosidae haves been studiapproached in Chile before, their identity and biology are is still uncertain. T, thhe main goal of this work is to provide new records of distribution and biology, and corresponding variation based on molecular and morphological data, to propose a current classification for the Chilean Cecidosidae .
