In the New World, weevils have been found in Mexican and Dominican amber as well as in Colombian copal. About 120 species of the families Belidae, Rhynchitidae, Attelabidae, Bren- tidae, Curculionidae, Scolytidae, and Platypodidae have recently been described from Dominican amber (Bright and Poinar, 1995; Davis and Engel, 2006a, 2006b, 2006c, 2007a, 2007b, 2009; Poinar, 2009; Poi- nar and Brown, 2011; Poinar at all., 2013, 2016; Poi- nar and Legalov, 2014a, 2014b, 2014c, 2014d, 2015a, 2015b, 2015c, 2015d, 2015e, 2015f). So far, only one rhynchitid species (Eugnamptus proterus Poinar et Brown, 2007); three weevil species (Semnorhynchus hurdi (Zimmermann, 1971), Neoulosomus sp. (Cryp- torhynchini), and Geratozygops durhami (Zimmer- mann, 1971) (Zygopini); and five Platypodidae species (Cenocephalus hurdi Schedl, 1962, C. quadrilobus Schedl, 1962, C. succinicaptus Schedl, 1962, C. tenuis Peris et Solórzano Kraemer, 2015, Tesserocerus simo- jovelensis Peris et Solórzano Kraemer, 2015) have been described from Mexican amber (Schedl, 1962; Zimmermann, 1971; Poinar and Brown, 2007; Poi- nar and Legalov, 2014b, 2014c; Peris et al., 2015); Solórzano Kraemer (2007) also provides a photo- graph of a beetle of the subfamily Cossoninae (Cur- culionidae). The present study describes the first representative of the subfamily Curculioninae from Mexican amber. MATERIAL AND METHODS The specimen comes from an amber mine in the northern mountain ranges or Chiapas Highlands of the Simojovel area in Chiapas, Mexico. Maps of the area were presented by Poinar (1992) and Solórzano Kraemer (2010). Amber from Chiapas, which was produced by Hymenaea mexicana (Fabaceae) (Poinar and Brown, 2002), occurs in lignitic beds among sequences of primarily marine calcareous sandstones and silt. The amber is associated with La Quinta For- mation, Balumtun Sandstone and Mazantic Shale with radiometric ages from 15 to 20 Ma (Solórzano Kraemer, 2007).

The new species is close to A. cruraluma Poinar et Legalov and differs from it in the wider elytra with narrow striae and strongly swollen pro- and metafemora. It differs from A. browni Poinar et Legalov in the wide and short elytra, shorter and thicker weakly curved rostrum, and strongly swollen metafe- mur. It is distinguished from A. camoiranensis Clark by the metatitibia with uncus and from A. sulcatus Kirsch by the protibia with uncus, metatibia with ventral fringe of medium scales, narrower elongate pronotum, weakly convex elytra and weakly curved rostrum.
