Platyrrhinus helleri
(Peters)
VOUCHER MATERIAL:
9 females (AMNH *266254, *267182, *267551, *267554, *267555, *268540; MNHN *1995.1187, *1995.1188, *1995.1189) and 5 males (AMNH *267179, *267550, *268541, *268542; MNHN *1995.1190); see table 44 for measurements.
IDENTIFICATION: A key to the species of
Platyrrhinus
was provided by
Ferrell and Wilson (1991)
, and
Anderson (1996)
helpfully reviewed characters distinguishing
P
.
helleri
from
P
.
brachycephalus
(see also
Rouk and Carter, 1972
). Other useful descriptions and measurements of
P
.
helleri
can be found in Sanborn (1955),
Goodwin and Greenhall (1961)
,
Husson (1962
, 1978),
Gardner and Carter (1972)
,
Rouk and Carter (1972)
, Swanepoel and
Genoways (1979)
,
Brosset and CharlesDominique (1990)
, and Anderson (1997). Two subspecies of
P
.
helleri
are currently recognized, of which
P
.
h
.
incarum
ranges throughout Amazonia, including the Guianas (Koopman, 1994).
Our Paracou specimens conform closely with previous descriptions of
Platyrrhinus helleri
. Although some populations (e.g., in Bolivia;
Anderson, 1996
) exhibit variation in the number of accessory cusps present on the anterior margin of the second lower premolar, all of our vouchers have only a single accessory cusp in this location. Measurements of the Paracou series (table 44) fall within the range of variation previously reported for
P
.
h

incarum
.
FIELD OBSERVATIONS: We captured 14 individuals of
Platyrrhinus helleri
at Paracou, of which 11 were taken in groundlevel mistnets and 3 in elevated mistnets. Four groundlevel captures were in welldrained primary forest, one in swampy primary forest, two in creekside primary forest, two in manmade clearings, and two over roadside puddles. The three elevated net captures were made between 6 and 21 m above a narrow dirt road.
