Molossus coibensis Allen, 1904

VOUCHER MATERIAL (TOTAL = 6): Jenaro Herrera (ROM 122087, 122091, 122130, 122177, 122254, 122255); see table 63 for measurements.

UNVOUCHERED OBSERVATIONS: None.

IDENTIFICATION: Molossus coibensis , which is now known to include M. barnesi (see Catzeflis et al., 2016; Loureiro et al., 2019), is distinguished from other congeneric species by its small size (forearm 33–38 mm, greatest length of skull 15–17 mm); short (<3.5 mm), unicolored dorsal fur varying from cocoa-brown to blackish; quadrangular occipital complex; and upper incisors with convergent tips (Eger, 2008; Loureiro et al., 2018a). Descriptions and measurements of the species (as M. coibensis or M. barnesi ) were provided by Dolan (1989), Simmons and Voss (1998), Lim and Engstrom (2001b), Díaz (2011), Catzeflis et al. (2016), and Loureiro et al. (2018a, b, 2019). No subspecies are currently recognized (Eger, 2008).

Loureiro et al. (2018b) correctly identified the specimens from Jenaro Herrera, which conform
