[Mammalogy • 2018] Uncovering the Diversity of Dog-faced Bats from the Genus Cynomops (Chiroptera: Molossidae), with the Redescription of C. milleri and the Description of Two New Species; Cynomops freemani & C. tonkigui

Cynomops freemani 
Moras, Gregorin, Sattler & Tavares, 2018

Until recently the genus Cynomops (Chiroptera: Molossidae) comprised six species of fast flying, aerial insectivorous bats distributed throughout the Neotropics. However, our revisionary study have shown that the diversity of this taxon was underestimated as molecular and morphological data supported the recognition of C. milleri as a full species and revealed two previously unrecognized, small species of Cynomops. These newly recognized taxa are Cynomops freemani sp. nov. from the Canal Zone region, Panama, sister taxon to C. mexicanus, and Cynomops tonkigui sp. nov. from the eastern Andes of Ecuador and Colombia, sister taxon of C. milleri. We also describe the calls of Cynomops freemani sp. nov. that may be useful for the recognition of these species during field inventories based on ultrasonic recording techniques. We elevate the currently known diversity of Cynomops to eight species, as we also revalidate C. milleri providing an emended diagnosis and a redescription of this taxon.

Cynomops freemani, new species 
Freeman’s Dog-faced Bat

ETYMOLOGY: The name “freemani” is in honor to Dr. Patricia W. Freeman in recognition of her influential contributions to the study of the morphology, systematics, and evolutionary relationships of molossid bats (e.g. Freeman, 1981).

DISTRIBUTION: Cynomops freemani is known from lowlands (23–53 m a.s.l.) of the Pacific coast of the Canal Zone region in Panama (Fig. 3).

Cynomops tonkigui, new species 
Waorani Dog-faced Bat

ETYMOLOGY: The name “tonkigui” is used as a noun in apposition, and means "bat" in the Waorani language. The name honors the Waorani people who inhabit the type locality (Tirira, 2012)

DISTRIBUTION: Cynomops tonkigui is known from the lowlands (195–529 m a.s.l.) of northeastern South America, and the eastern slopes of the Andes in Ecuador and Colombia (Fig. 3).
