Ectophylla
Phylogenetic relationships between
Ectophylla
,
Mesophylla
, and
Vampyressa
have been the subject of much debate in the literature. Most workers have retained all three as distinct genera (e.g.,
Hall, 1981
;
Koopman, 1993
, 1994), but some authors have considered
Mesophylla
to be a junior synomym of
Vampyressa
(e.g.,
Owen, 1987
) or of
Ectophylla
(e.g., Goodwin and Greenhall, 1962; Handley, 1976). Recently, Peffley et al. (MS) found strong support for a sistergroup relationship between
Ectophylla
and
Mesophylla
, both of which are monotypic, and argued that
Ectophylla alba
H.
Allen (1892)
and
Mesophylla macconnelli
Thomas (1901a)
should be placed in a single genus to reflect this relationship. We therefore use the older generic name for both species, and provide a formal diagnosis for
Ectophylla
as so defined.
EMENDED DIAGNOSIS OF
ECTOPHYLLA
: Size
small (weight less than 11 g and forearm length less than 35 mm); dorsal and ventral fur pale buff, grayish white, or white; no white facial stripes or middorsal stripe; skin of noseleaf, ears, and thumb bright yellow; ventral border of narial horseshoe defined by a free flap of skin; uropatagium short, naked, translucent; length of calcar less than onehalf length of hindfoot; dental formula I 2/2, C 2/2, P 2/2, M 2/2–3 x 2 = 28–30; rostrum approximately threefourths the length of the braincase; rostrum not inflated and without a deep depression or long nasal emargination; interpterygoid space not extended by a deep palatal emargination; inner upper incisors elongate, unworn crown height more than twice that of outer incisors; inner upper incisors not deeply bifid; m1 without posterolingual cusp (crown resembles that of last premolar); lingual cusps of m2 vestigial or absent.
