Abstract

Trictenotoma davidi Deyrolle, 1875 and T. formosanaKriesche, 1919 are the only insular Palaearctic Trictenotomidae. Both species are related and T. formosana was originally defined on the basis of unstable morphological features and originally described as a subspecies of T. davidi. In this paper, a detailed redescription of T. formosana is provided, male and female genital organs are described and illustrated for the first time and the lectotype is designated. Hainan (China) records of T. davidi are presented and morphological variability of this taxon is discussed. The first observation of Trictenotomidae mating behaviour is briefly described.
