Microberotha

Microberotha is an extinct monotypic genus of "beaded lacewing" in the family Berothidae known from a fossil found in North America. When described the genus contained a single Ypresian-age species Microberotha macculloughi.

History and classification
The genus is known from a single male specimen, the holotype, currently deposited in the collections of the Kelowna Centennial Museum in Kelowna, British Columbia, as number "NH.998.015.002". The type specimen is well preserved in early Early Eocene The placement of the three genera in Cyrenoberothinae was fully affirmed by Machado et al. (2022) when they reevauated the subfmaily and described the first cave dwelling berothid genus Speleoberotha. ==Description==
Description
Microberotha can be distinguished from other berothids by the combination of an unbranched "Rs" vein and lack of an outer gradate series of crossveins in the forewings. With a forewing length of only , M. macculloughi is one of the smallest known members of Berothidae to have been described. The smallest living species, Manselliberotha neuropterologorum, has a minimum forewing length of , while some species from the New Jersey ambers are smaller at a minimum of . The holotype is preserved in a specimen of amber which shows distinct flow patterning indicating it started as a "stalactite" or similar formation on the tree. The positioning of the insect relative to the flow pattern indicates it was most likely trapped with its back stuck to the inner flow with its left side facing down. A later, thicker flow covered the insect, twisting the left hindwing and disarticulating both the hindlegs. == References ==
