摘要

Five new species of the genus Lyconotus Green, 1949 are described from Mexico. The new species include L. zuritai sp. n. from Yucatán, L. chamelensis sp. n. from Jalisco, L. nunu sp. n. from Guerrero, L. soyaloensis sp. n. from Chiapas, and L. kuaan sp. n. from Oaxaca. These species can be distinguished from one another by a number of characters, including differences in body colouration, length of rostrum, length of radial cross-vein 3 in comparison with radial cell, form of sternellum, and male genitalia (length of parameres and the lateral projections on the phallus). In females, variation is observed in the posterior margin of sternite VII and genitalia, particularly the shapes of the valvifers and proctiger. The description of these five species in the Neotropical region of Mexico establishes the country as a center of endemism, with 85% of the species of the genus found in the area. A distribution map and a key to the species of the genus are provided for reference.
