The Neotropical genera of Acanthocinini Blanchard, 1845 (Coleoptera: Cerambycidae: Lamiinae) with the third antennomere modified

Description of two new species of Xenocona Gilmour (Coleoptera, Cerambycidae, Lamiinae) from Ecuador

“…Later, Gilmour (1962 described Alcathousites to include A. chaclacayoi Gilmour, 1962. Monné (2004 synonymized A. chaclacayoi with A. asperipennis (Fairmaire & Germain, 1859), and Nascimento & Botero (2019) synonymized Alcathousites with Xenocona, with consequent transference of Alcathousites senticosus Monné & Martins, 1976, A. superstes (Erichson, 1847, and A. asperipennis (Fairmaire & Germain, 1859), and transferred Lophopoeum forsteri Tippmann, 1960 to Xenocona. Currently, Xenocona includes seven species distributed through Central America and northern South America (Monné, 2022;Tavakilian & Chevillotte, 2022).…”

A review of the genus Alcathousiella Monné, 2005 (Coleoptera, Cerambycidae)

“…Finding that the name Alcathous was preoccupied by Alcathous Stål, 1863 (Hemiptera), Monné (2005) replaced it with Alcathousiella. The genus has since been associated (Nascimento & Botero 2019) with a group of genera of Acanthocinini Blanchard, 1845 (Alcathousiella Monné, 2005, Amniscites Gilmour, 1955, Odontozineus Monné, 2009, Xenocona Gilmour, 1960and Xenostylus Bates, 1885 with the following characters: antennomeres III-XI elongated, elytra without erect setae and without lateral carinae, elytra with central basal crest, with or without erect setae on apex, mesoventral process without tubercle, antennomere III with internal apical spine in the males. In their paper they redefined the above genera and provided a key to separate them.…”
