This species was first encountered in 1984 in Colombia. Its species name chocoensis is derived from the region where it was found, the Chocó Department.[4] A morphological study suggested that it may be the most basal (earliest offshoot) of its genus,[5] however, another study using DNA suggested that the Platyrrhinus of the Chocó region diverged from Platyrrhinus of the Amazonian Craton, and that the white-lined broad-nosed bat was more basal.[6]
Description
Their forearms are 47–51 mm (1.9–2.0 in) long. They have a single whisker on their upper lip,[7] and seven whiskers surrounding their nose-leaf.[8] They have dark facial stripes. Their ears have well-defined folds.[8] They have narrow dorsal stripes. Individual dorsal hairs are tricolored, with the base, mid, and tip of the hair different colors; ventral hairs are bicolored. The third metacarpal is shorter than the fifth metacarpal. They weigh approximately 30 g (1.1 oz), making them "medium-sized" for their genus.[8]
This species has been documented in two sites in the lowland of southern Panama. It has been found in over twenty sites in both Colombia and Ecuador. They live in the Pacific-facing side of Colombia and western Ecuador. They are found in lower elevation habitat, from 1–1,000 m (3.3–3,300 ft) above sea level.[1]
