{"title":"A Miocene ant species of the genus Forelius Emery, 1888 (Hymenoptera: Formicidae: Dolichoderinae) from Mexico","authors":"Fernando Varela-Hernández, Francisco Riquelme, Roberto Guerrero","doi":"10.26879/1294","DOIUrl":"https://doi.org/10.26879/1294","url":null,"abstract":"The first fossil ant species of the New World genus Forelius (Formicidae: Dolichoderinae) is described. The type material is a Miocene amber inclusion from the Montecristo mine near Simojovel, Chiapas, southwestern Mexico. The new species is named Forelius chenpauch sp. nov. It differs from its congeners by having a unique combination of characters: antennal scapes reaching the posterior margin of the head; pronotum with six erect hairs; mesonotum with four erect hairs; propodeum with four erect hairs; front and dorsum of head, dorsum of pronotum, dorsum of mesonotum and propodeum covered with a fine striation. Forelius chenpauch sp. nov. has a rounded spiracle, which could be considered a plesiomorphic character closely related to the Forelius group from the north of the Amazon basin. Accordingly, the current divergence estimates of Forelius as a single genus from the Leptomyrmex + Forelius + Dorymyrmex clade (ca. 27 Ma) and the occurrence of Forelius chenpauch sp. nov. in the fossil record (ca. 23 Ma), may suggest that the rounded spiracle is a plesiomorphic state probably widespread since the Miocene from southern Mexico to northern South America.","PeriodicalId":49139,"journal":{"name":"Palaeontologia Electronica","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135496023","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
