Comment on the collection technique (Bellò et al. 2021): Both specimens of G. amicorum were collected using endogean pitfall traps placed in a calcareous environment covered by degraded Mediterranean shrub on the SSW slope of Mount Paramythyás, at 620 meters of elevation. The traps were set on 23rd June 2014 and recovered on 20th September 2015. It is plausible that the new species has a biology similar to those of other endogean weevils, which have rhizophagous adults and larvae developing inside roots, not necessarily in the deepest part of the soil.
