Abstract

The Palaearctic longhorn beetle Stictoleptura cordigera (Füssli, 1775) (Cerambycidae: Lepturinae: Lepturini) is recorded for the first time in Chile, based on specimens collected in a rural locality of the Maule Region. This new record is the first in the New World and increases to eleven the number of exotic cerambycids introduced and established in the Chilean territory. A brief diagnosis for recognition of the species and data about its distribution and natural history are provided. The possible route of entry of this cerambycid into Chile is discussed.

Stictoleptura cordigera (Füssli, 1775) is a polyphagous, saproxylic, anthophilous cerambycid widely distributed in southern Europe and the Middle East (Sama 2002; Sama et al. 2010).

In December 2020, the second author (GR) collected floating in the pool of a house one male specimen of S. cordigera in Ranquimilí, Las Rastras, Talca (35°26′01″S, 71°32′43″W), a rural area of the Maule Region in central Chile (Fig. 3). Subsequently, in November and December 2022, an additional male and two female specimens were collected in the same place and under the same circumstances.

Stictoleptura cordigera is the eleventh cerambycid reported as adventive in Chile, in addition to Nathrius bre­vipennis (Mulsant, 1839), Phoracantha semipunctata (Fabricius, 1775), P. recurva Newman, 1840, Ambeodontus tristis (Fabricius, 1775), Xylotrechus (Rusticoclytus) rusticus (Linnaeus, 1758), Aegomorphus jaspideus (Germar, 1824), Hylotrupes bajulus (Linnaeus, 1758) (Sandoval 2002; Barriga and Cepeda 2007; SAG 2008; Mondaca and Zavala 2016; González et al. 2018); and three species restricted to Rapa Nui island: Ceresium unicolor unicolor (Fabricius, 1787), Lagocheirus obsoletus Thomson, 1860 and Sybra alternans (Wiedemann, 1823) (Cerda 1991; Mondaca 2008; Mondaca et al. 2016).

The objective of this note is to communicate the presence of S. cordigera in the national territory from adult specimens collected in two different years in the Maule Region, being the first report of this longhorn beetle for Chile and for the New World.
