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.
