Blepharotoma Blanchard is the second largest genus of the tribe, and due to undergoing several new descriptions and transferences over the years has its intern limits become uncertain. Geometric morphometrics has been helping identify patterns among groups of organisms with uncertain limits. This method enables the identification of variations in shape among specimens through comparisons of landmarks coordinates. The aim of the present study was to test the existence of significant morphometric variation among the genera of Sericoidini and species of Blepharotoma that could enable identifying taxa. We analyzed the clypeus, pronotum and elytra of species of each genus of Sericoidini and 18 valid species of Blepharotoma. A photographic matrix was created with images of the structures and a set of landmarks was plotted in each image. Procrustes superimposition was performed, and the data were analyzed using principal component analysis (PCA), Procrustes ANOVA and canonical variate analysis (CVA). Groups for CVA were classified by genera, species and collection site. The results showed that genera of Sericoidini have a shape pattern. In contrast, species of Blepharotoma do not have any specific pattern, except for the population from Buenos Aires (unidentified species).

We investigate an adult paratype specimen of H. higginsi, and young adult specimens of H. spinulosus from the Beaufort Sea and H. spinulosus from Kandalaksha Gulf, White Sea. Molecular analysis of the mitochondrial CO1 gene confirm the existence of two species of Halicryptus, a wide distribution of H. spinulosus across the Northern Hemisphere and the co-occurrence of both species in the Beaufort Sea. Our morphological analyses reveal undocumented characters for Halicryptus, such as the presence of three different sizes of buccal papillae, scattered small trunk papillae, and a loose ring of flosculus-tubulus-complexes on the posterior trunk. For both species, we revise characters, such as the number of long introvert retractors, pharynx protractors and lateral cusps of anterior teeth, and the maximum number of scalids in a row in H. spinulosus. We propose a total of ten reliable and potential diagnostic characters distinguishing the two species and revise the terminology of Halicryptus-specific characters due to inconsistency in the literature.
