Nuevos registros de la chinche de las coníferas occidental Leptoglossus occidentalis Heidemann (Heteroptera: Coreidae) en Chile RESUMEN. Se presentan nuevos registros de la chinche de las coníferas occidental Leptoglossus occidentalis en Chile, de las regiones de la Araucanía, Los Ríos y Los Lagos. Los nuevos registros extienden su distribución conocida en el país cerca de 650 km hacia el sur.

The Chilean Pentatominae species are listed and catalogued; a total of 18 species have been accounted. Additionally 3 species present doubtful or incomplete records. Most of the species are endemic to South America; 2 species are considered introduced in Chile, and 6 species are exclusively Chilean.

The arrival and establishment of the bed bug Cimex lectularius L., 1755 in Magallanes Region (Chile) is reported. The present record is the southernmost for this species in America. The circumstances that provided for the species reaching this southern locality are discussed.

Leptoglossus occidentalis (Heidemann) is an invasive species introduced in Europe, Asia, and most recently South America. In the present study, we report the overreaction situation caused by this bug in Chile, as it has been confused with kissing bugs (Reduviidae: Triatominae), Chagas’ disease vectors. During 2018 and first months of 2019, we received 74 alleged cases of kissing bugs to confirm identification. From these, a total of 63 were identified as L. occidentalis, representing a 85% of the total denounces. Additionally, the first bite case in a human is described. The situation caused by L. occidentalis in Chile is discussed, and an illustrated table is provided to correctly identify this species and tell it apart from Triatomines. It is concluded that L. occidentalis is well established in Chile, and it is necessary to educate the population on recognition of the bug and to avoid overreaction as the species can inflict painful bites, but not transmit any disease.

Sinopla humeralis Signoret, 1864 is revalidated and removed from the synonymy of Sniploa obsoletus Signoret, 1864. The first formal records from it original description and first data about its biology are provided. The type species of the genus Sinopla is discussed and the concept of the genus is expanded. The association of Sinopla humeralis with the southern beech Nothofagus Blume and it distribution from Maule Region to Magallanes Region in Chile, are inncluded.
