Remarks: This species was described by Williamson (1919) based on a series of 33 males and 17 females collected in a couple of weeks. Bota-Sierra (2016) catalogued it in the IUCN red list as Critically Endangered (CR) because, since its discovery by Williamson in 1917, it had not been found again. Despite of sampling efforts at the type locality and surrounding areas, where a large amount of its habitat had disappeared. Bota-Sierra & Novelo-Gutiérrez (2017) presented images of color pattern of head and thoracic intersternites of paratypes deposited in Rosser W. Garrison personal collection (RWG). We rediscovered this species at new localities in Chocó and Risaralda Departments. Photographs of male cerci ( Fig. 11View FIGURE 11 A–C), female intersternite, genital valves ( Fig. 15View FIGURE 15 G–I) and head color pattern ( Fig. 6View FIGURE 6 E–F) are presented.

Color pattern of head of males is very similar to H. angustipenne  because of the black postclypeus, but H. peregrinum  differs in having abdomen length close to 35mm, while in H. angustipenne  abdomen is longer than 39mm, and the angle between medial process and tip of cerci is close to 90° in H. angustipenne  ( Fig. 7DView FIGURE 7), but close to 45° in H. peregrinum  ( Fig. 11AView FIGURE 11). Female is characterized by having an intersternite with a digitiform dorsal plate ( Fig. 15IView FIGURE 15).
