INTRODUCTION

The tribe Elaphidiini Thomson, 1864 is remarkably diverse in the Cerambycidae family, represented by 634 species in 93 genera (Tavakilian & Chevillotte, 2020Tavakilian, G. & Chevillotte, H. 2020. Titan: base de données internationales sur les Cerambycidae ou Longicornes. Version 3.0. Available at: Available at: http://titan.gbif.fr . Access in: 07/2020.

), with distribution in the Americas, mainly in the Atlantic and Amazon forest (Martins, 2005Martins, U.R. 2005. Tribo Elaphidionini. In: Martins, U.R. (Org.). Cerambycidae Sul-americanos (Coleoptera). Taxonomia. Curitiba, Sociedade Brasileira de Entomologia. v. 7, 394p.). Morphologically is characterized by the presence of antennal and tibial carinae, and abruptly rounded anterior margin of the mesonotum (Lingafelter, 1998Lingafelter, S.W. 1998. The genera of Elaphidiini Thomson 1864 (Coleoptera: Cerambycidae). Memoirs of the Entomological Society of Washington, 20: 1-118.; García & Nascimento, 2020García, K. & Nascimento, F. 2020. Elaphidiini (Coleoptera: Cerambycidae) from the Caribbean region of Colombia: New species, taxonomic notes and new geographical records. Papéis Avulsos de Zoologia, 60(23): 1-8. DOI).

In the neotropical region, Stizocera Audinet-Serville, 1834 is one of the most diverse genera of Elaphidiini, and is currently composed of 53 species (Monné, 2020Monné, M.A. 2020.

). Its distribution extends from Mexico to Argentina, with most of its species distributed mainly in the Atlantic forest (Martins, 2005Martins, U.R. 2005. Tribo Elaphidionini. In: Martins, U.R. (Org.). Cerambycidae Sul-americanos (Coleoptera). Taxonomia. Curitiba, Sociedade Brasileira de Entomologia. v. 7, 394p.; Monné, 2020Monné, M.A. 2020.

). Martins (2005Martins, U.R. 2005. Tribo Elaphidionini. In: Martins, U.R. (Org.). Cerambycidae Sul-americanos (Coleoptera). Taxonomia. Curitiba, Sociedade Brasileira de Entomologia. v. 7, 394p.) revised Stizocera species from South America and included 33 species. In that work, a key to South American species was provided and remains as the most complete and recent available.

Currently, seven species are recorded for Colombia (Martínez, 2000Martínez, C. 2000. Escarabajos Longicornios (Coleoptera: Cerambycidae) de Colombia. Biota colombiana, 1(1): 76-105.; Martins & Galileo, 2003Martins, U.R. & Galileo, M.H. 2003. Cerambycidae (Coleoptera) da Colômbia. IV. Cerambycinae com olhos grosseiramente granulados.

Herein Stizocera ruthveronae sp. nov., is described and illustrated. The key proposed by Martins (2005Martins, U.R. 2005. Tribo Elaphidionini. In: Martins, U.R. (Org.). Cerambycidae Sul-americanos (Coleoptera). Taxonomia. Curitiba, Sociedade Brasileira de Entomologia. v. 7, 394p.) is translated and updated. Additionally, nine species of longhorn beetles belonging to six tribes of Cerambycinae (Callichromatini, Eburiini, Elaphidiini, Hexoplonini, Neoibidionini, Obriini) are reported for the first time for Colombia.

Etymology: The species epithet is in honor of Ruth Verona Anaya, mother of the first author, for your love, understanding and constant support.

Remarks:Stizocera ruthveronae sp. nov., is similar to S. asyka Galileo & Martins 2004, S. nigroflava Zajciw 1965 and S. tristis (Guérin-Méneville, 1844) by the body covered of long and dense setae; integument color and meso and metafemora pedunculate and bispinose. Stizocera ruthveronae sp. nov., differs by antennomeres III-VIII armed (antennomeres III-V armed in those species, in S. nigroflava the antennomere VI can be also armed) and pronotum with four gibbosities poorly elevated. Other characteristics used to differentiate S. ruthveronae sp. nov. can be observed in the following key.
