VOUCHER MATERIAL:
El Diamante
:
1 adult
female (

),
2 adult
males (
FMNH 203522
;
MUSM 39189
)
; see table 6 for measurements.
IDENTIFICATION: Descriptions and measurements of
Diphylla ecaudata
have been provided by
Swanepoel and Genoways (1979)
,
Greenhall et al. (1984)
, and
Kwon and Gardner (2008)
. Currently two subspecies are recognized:
D. e. centralis
(southern
United States
southward through eastern
Mexico
and Central America) and
D. e.
ecaudata
(
Venezuela
,
Colombia
,
Ecuador
,
Peru
,
Bolivia
, and
Brazil
, excluding the central Amazon basin) (
Greenhall et al., 1984
;
Kwon and Gardner, 2008
). Our Mayo River basin specimens exhibit the diagnostic characteristics of the species: thumb small (usually less than
13 mm
), lacking basal pads; uropatagium well furred; occlusal margin of lower inner incisors with four lobes, of lower outer incisors with three lobes; two upper incisors and two lower molars on each side (
Kwon and Gardner, 2008
;
Cirranello et al., 2016
). Our Mayo River basin voucher material represents the nominate subspecies.
