Diagnosis

Adult specimens measure between 1.5 and 2.5 cm (total length) and have a brown or black body colouration. It can be distinguished from L. gonagra by its broadly rounded humeral angles of the pronotum, a brown pronotal disc with several round black spots, underside of body without contrasting large yellow spots and smaller and narrower foliar dilations of the tibiae (Fig. 1 A). In contrast, L. gonagra has humeral angles of the pronotum that end in a spine, an orange line crossing the anterior part of the pronotal disc, underside of body covered with large contrasting yellow spots and larger and wider leaf-shaped dilations of the posterior tibiae with teeth on the external part (Fig. 1 B).

Distribution

North America, Canada, United States, South America, Europe, Asia and Africa ( Brailovsky 2014, Lesieur et al. 2014, Faúndez et al. 2017, Carpintero et al. 2019, van der Heyden and Faúndez 2020, Bánki et al. 2023).

Habitat

The current distribution of the species can be found at Fig. 1 C. The first individual was detected in Tafira Alta, Las Palmas de Gran Canaria (28.0524757, -15.465979), in early October 2022. Since then, the locality has been monitored by technicians during five months and fourteen additional individuals have been found (see 'Materials and Methods').

Genetic data

A 658-bp fragment was succesfully amplified (GenBank accession code: OR268561). BOLD identification resulted at species level identification with a 100% correlation, with the specimen from Gran Canaria sharing haplotype with continental specimens from Canada, Germany, Hungary, USA and South Korea (Fig. 1 D).
