Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Three new genera and species of Cenomanian Cixiidae from Kachin amber (Myanmar) are described: Acrotiara Bourgoin & Luo gen. nov., type species A. multigranulata Luo & Bourgoin sp. nov., Delphitiara Bourgoin & Luo gen. nov., type species D. tibiocoronata Luo & Bourgoin sp. nov., and Pentacarinus Bourgoin & Luo gen. nov., type species P. kachinensis Luo & Bourgoin sp. nov. A key to identification of these new genera is provided. These cixiids with a pentacarinated mesonotum belong to a new tribe Acrotiarini Bourgoin & Luo trib. nov., type genus Acrotiara gen. nov., which is characterized by a specific set of characters, some being unique in the family Cixiidae such as the paired sublaterofrontal carinae and the arched RA on the tegmina. This new taxon prompts discussion of the current classification and phylogeny of the family, which remains widely unexplored, and of the evaluation of the placement of two older cixiid fossils currently known, Karebodopoides aptianus (Fennah, 1987) and Cixius petrinus Fennah, 1961. A new genus, Barremixius Bourgoin & Szwedo gen. nov., is proposed for the latter, resulting in the new combination Barremixius petrinus (Fennah, 1987). Karebodopoides Szwedo, 2001 and Barremixius gen. nov. are provisionally recognized as the oldest Cixiidae, respectively representative of the oecleinian lineage (including Bothriocerini trib. stat. nov.) and of the cixiinian lineage. Acrotiarini trib. nov. belongs to the pentastirinian lineage (including Borysthenini stat. nov.). All these fossils depict that the first main division that occurred in Cixiidae, occurred much earlier during the Cretaceous
