Type locality: Holotype male: Peru, Cusco, Pillcopata, Manu Biological Station. Coordinates: -12.8955, - 71.4038, Altitude: 550 m.a.s.l., 16-IV-2023, Méndez-Cardona S. Coll.
Type material: Holotype permanent mount on a microscope slide deposited at Museo de Historia Natural Universidad Nacional Mayor de San Marcos UNMSM, Lima, Peru. Nine paratype males as follows: 1 male (Museo de Historia Natural UNMSM), six males (INS09120–25 Laboratorio de Entomología, Instituto Nacional de Salud, Bogotá, Colombia), two males (Florida State Collection of Arthropods FSCA, Gainesville, FL, USA). Paratype males same data as holotype, but collected between March and April 2023.
Etymology: The name Th. macrisae is given in homage to María Cristina Carrasquilla Ferro for her contributions in the field of medical entomology in Colombia and her role as a mentor in the professional development of the first author.
