VAN DER HEYDEN (2023) published the first part of a series of new records of Heteroptera from the
Canary Islands. In this note, more new records from the archipelago are reported. The known
distribution of the species mentioned in this note was checked by using various checklists (AUKEMA et
al., 2006, 2013; RIEGER, 2020; ROCA-CUSACHS et al., 2020). Furthermore, the online databases Banco
de Datos de Biodiversidad de Canarias (GOBIERNO DE CANARIAS, 2023) and Catalogue of Palaearctic
Heteroptera (AUKEMA, 2023) were consulted. All new records reported in this note are based on
photographic records uploaded to the online database iNaturalist.
Dieuches schmitzi Reuter, 1893 (Heteroptera: Rhyparochromidae) was reported by AUKEMA et al.
(2006, 2013) and ROCA-CUSACHS et al. (2020) for the islands of La Palma, La Gomera, Tenerife and
Gran Canaria. RIEGER (2020) added the island of Fuerteventura to the list of its distribution on the
Canary Islands. The island of Lanzarote can be added to the list: On 28-06-2020, an adult specimen of
D. schmitzi was photographed in El Jablillo near Costa Teguise in the eastern part of the island (see
here).
AUKEMA et al. (2006, 2013) and ROCA-CUSACHS et al. (2020) reported Cydnus aterrimus (Forster,
1771) (Heteroptera: Cydnidae) for the islands of El Hierro, La Palma, Tenerife, Gran Canaria,

Fuerteventura and Lanzarote. The species was found on the island of La Gomera, too: On 22-05-2022, a
nymph was photographed southwest of Alojera, near the northwestern coast of the island (see here).
Halyomorpha halys (Stål, 1855) (Heteroptera: Pentatomidae) has not been reported for the Canary
Islands, yet. This invasive Asian species has to be added to the list of Heteroptera which are present
on the archipelago, as the species was found on the island of Tenerife: On 17-12-2021, the second
author found and photographed an adult specimen of H. halys (Fig. 1) in an urban environment in Costa
Adeje at the southwestern coast of Tenerife (see here). Within the next few days more adult
specimens were seen (Fig. 2). In total, at least six specimens were found, of which four were collected
and handed over to the local plant health agency. Furthermore, on 07-03-2023 an adult specimen of H.
halys was photographed by another observer in the vicinity of the first cluster of records in Costa
Adeje, suggesting an established population. These records represent a dramatic species expansion and
raise important questions about the species demography and potential economic and biodiversity
impacts on Tenerife. The population could also act as a source for invasion of other Canary Islands.
