History and classification
Astreptolabis ethirosomatia is known only from a single fossil, the holotype, specimen number AMNH Bu-FB20, which is housed in the Amber Fossil Collection of the American Museum of Natural History in New York City. The specimen is composed of a fully complete adult female earwig which has been preserved as an inclusion in a transparent chunk of Burmese amber.[1] The age of the amber deposits in Kachin State of northernmost Burma are understood to be about 100 million years old, placing them in the earliest part of the Cenomanian stage of the Cretaceous.[2] The Astreptolabis ethirosomatia holotype was recovered from outcrops near the city of Myitkyina in Kachin State and was first studied by paleoentomologist Michael S. Engel of the Division of Entomology at the University of Kansas in Lawrence, Kansas.[1] Engel's 2011 type description of the new species was published in the online journal ZooKeys.[1] The genus name Astreptolabis was coined by Engel as a combination of Greek words astreptos, which means "not curved" and labis, which means "forceps". This is in reference to the distinct structuring of the type specimens cerci or "pincers". The specific epithet ethirosomatia is from the Greek words etheira, meaning "hairy" and somation, the diminutive of the Greek word for "body". The subfamily name Astreptolabidinae is derived from the genus name with the suffix -inae added.[1] In 2020 a second species. A. laevis was described.[3]
