Abstract
Lepidura Townes is a genus with an Andean distribution of the subfamily Mesochorinae, occurring in Chile and Argentina. Among the 14 species described, the males remain unknown in seven: L. callaina Dasch, L. improcera Dasch, L. mallecoensis Dasch, L. nigricephala Araujo & Vivallo, L. patagonica Araujo & Vivallo, L. seminitida Araujo & Vivallo and L. viridis Dasch. Based on the study of specimens deposited in the Museo Argentino de Ciencias Naturales “Bernardino Rivadavia”, Argentina, the male of L. patagonica is described and illustrated for the first time. In addition, a new distribution record of L. olivacea Dasch in Argentina is also provided
Highlights
Mesochorinae is a moderately large species-rich group of specialized hyperparasitoids (Broad et al., 2018), with approximately 880 species (Yu et al, 2016)

Summary
Mesochorinae is a moderately large species-rich group of specialized hyperparasitoids (Broad et al., 2018), with approximately 880 species (Yu et al, 2016). Distribution restricted to the Andean ovipositor short and needle-like (Wahl, 1993; Araujo et biogeographic zone (sensu Morrone, 2015), with species al., 2018). Genera of the Mesochorinae, knowledge about biology Vivallo (Chile), L. olivacea Dasch (Argentina and Chile), and behavior of the species of Lepidura is scarce. Araujo & Vivallo (2018) provided an updated Dasch (Chile), L. seminitida Araujo & Vivallo (Chile), L. taxonomic revision for the genus and described L. tenebrosa Dasch (Chile), L. tuberosa Dasch (Chile), L. nigricephala, L. patagonica and L. seminitida based on variegata Dasch (Chile) and L. viridis Dasch Nigricephala, L. patagonica and L. seminitida based on variegata Dasch (Chile) and L. viridis Dasch The males of these species remain and Chile). We describe the male of L. patagonica and Lepidura olivacea Dash, 1974 provide a new distribution record of L. olivacea in Material examined: 1 female: RA Neuquén, S.
