9B13CF595170FFA71B5D29C2FBF8FD7E.taxon	diagnosis	Diagnosis Lycorectus gen. nov. is closely related to Rhyncheros. In both genera, the prosternum is strongly carinated, the mesosternum is slightly prominent, the internal angles of the metacoxae are blunt, and the metatibial spurs are equal and long. The main differences between Rhyncheros and Lycorectus are in the shape of the posterior border of the seventh sternite in males, which may be either concave or emarginate in Rhyncheros, but is slightly convex in Lycorectus. In addition, the phallus of Rhyncheros may or may not have thorns, whereas the phallus of Lycorectus lacks thorns (Fig. 10 C – E).	en	González-Ramírez, Mireya, Zaragoza-Caballero, Santiago, Morrone, Juan J., Ochoterena-Booth, Helga (2025): A phylogenetic analysis based on morphology reveals the placement of Lycomesus Zaragoza-Caballero & González-Ramírez, 2019 and Lyconotus Green, 1949 within Lycini (Coleoptera: Lycidae), with the description of a new genus from North America.

9B13CF595170FFA71B5D29C2FBF8FD7E.taxon	etymology	Etymology The name Lycorectus is derived from the Greek term ‘ Lykos ’ = ‘ wolf’ and Latin term ‘ rectus ’ = ‘ straight’. The latter pertains to the straight shape of phallus of the aedeagus in comparison to the same structure in Lycomesus and Lyconotus.	en	González-Ramírez, Mireya, Zaragoza-Caballero, Santiago, Morrone, Juan J., Ochoterena-Booth, Helga (2025): A phylogenetic analysis based on morphology reveals the placement of Lycomesus Zaragoza-Caballero & González-Ramírez, 2019 and Lyconotus Green, 1949 within Lycini (Coleoptera: Lycidae), with the description of a new genus from North America.

9B13CF595171FFA21BF02E13FCEBFAF8.taxon	diagnosis	Diagnosis Lycorectus sordidus gen. et comb. nov. is closely related to Rhyncheros championi. In both species, the elytra are weakly dilated, and the tibiae are strongly curved. The most notable differences between R. championi and L. sordidus are observed in the width of the rostrum. In R. championi, the rostrum is slender, whereas in L. sordidus, it is robust. The length of the antennae differs between the two species. In R. championi, the antennae are relatively short, while in L. sordidus, they are considerably longer. The width of the macula of the pronotum may be narrow in R. championi but is broad in L. sordidus. The colouration of the elytra is distinct in the two species. The humeral region and sides of the pronotum of R. championi are fulvous, whereas in L. sordidus, this colouration is limited to the humeral region. In addition, the colouration of the apex of the femora and the abdomen in R. championi is rufo-testaceous, whereas in L. sordidus it is dark brown.	en	González-Ramírez, Mireya, Zaragoza-Caballero, Santiago, Morrone, Juan J., Ochoterena-Booth, Helga (2025): A phylogenetic analysis based on morphology reveals the placement of Lycomesus Zaragoza-Caballero & González-Ramírez, 2019 and Lyconotus Green, 1949 within Lycini (Coleoptera: Lycidae), with the description of a new genus from North America.
