Type species

Lycus schoenherri Chevrolat, 1834 .

Diagnosis

Neolycus can be distinguished from Lycomesus , Lyconotus , Lycorectus gen. nov., and Rhyncheros by the presence of sexually dimorphic elytra, males with elytra considerably dilated in the middle, females with moderately dilated elytra ( Fig. 9D–E); membranous wing with the radiomedial loop broadly curved ( Fig. 5M); the metatibial spurs unequal, the inner acute, the outer slightly broader apically and bluntly rounded, and situated close to each other at the base ( Fig. 6E); the aedeagus with thorns on the phallus ( Figs 6T, 7A–B, G, J). In female genitalia, the valvifers are independent structures fused at the base ( Fig. 7L).

Redescription

Body slender. Head mostly concealed by pronotum, rostrum variable in length (often very long) ( Fig. 4B). Interantennal distance less than 0.09 mm. Antennomere III longer than antennomere IV ( Fig. 4E–F). Variable labrum shape (semi-square to rectangular) ( Fig. 4M). Mandibles as long as labrum. Pronotum widest at base, with variable anterior border shape (rounded to strongly angulated) ( Fig. 4R–S), and anterior margins not prominent, pronotal margin longer than 0.82 mm. Elytra with sexual dimorphism, male with considerably dilated elytra, female with moderately dilated elytra ( Fig. 9D–E), both sexes with four distinct costae on each elytron. Radiomedial loop broadly curved ( Fig. 5M). Trochanters with rounded internal angle ( Figs 5P, R–S, 6B), metatibial spurs unequal (inner acute, outer slightly broader apically and bluntly rounded) and long ( Fig. 6E). Male with straight last sternite. Male genitalia with variable shape of parameres (moderately short, or very long and triangular) ( Figs 6T, 7A), phallus slightly widened at base and straight to apex ( Fig. 7B, G), with a small and transparent keel on ventral part; phallus with thorns of variable length ( Figs 6T, 7A–B, G, J). Female genitalia with elongated stylus, coxites, and valvifers as independent structures, with coxites elongated and robust, valvifers fused at base ( Fig. 7L).

Distribution

Neolycus is distributed sympatrically with Rhyncheros throughout the Neartic and Neotropical regions, with records from southern United States and Mexico ( Dugés 1878, 1896; Gorham 1880, 1884; Green 1949; Pérez-Hernández et al. 2019; GBIF 2023b), and Peru ( Bocak et al. 2015).
