República del Ecuador

Teratohyla
amelie—
Guayasamin, Castroviejo-Fisher, Trueb, Ayarzagüena, and Vilà 2009
.
Background information.
This species was described on the basis of two adult males collected from a locality in the east-Andean foothills of central
Ecuador
. The combination of white visceral peritonea, green bones in life, transparent parietal peritoneum, humeral spines absent in adult males, bulbous liver, and dorsum lavender in preservative is unique among known centrolenid species.
Guayasamin
et al.
(2008)
provided molecular sequence data for a specimen identified as “
Cochranella
cf.
amelie
” from southern
Peru
, and
Guayasamin
et al.
(2009)
placed this species in the genus
Teratohyla
on the basis of genetics and morphology.
New data.
We have collected five specimens from two sites in northern
Peru
. Additionally, we have studied two specimens from southern
Peru
(one of them mentioned by
Guayasamin
et al.
2008
). These seven specimens fit the description of
Teratohyla amelie
,
which have a completely transparent parietal peritoneum, a character state only present in species of
Chimerella
,
Hyalinobatrachium
, and
Teratohyla pulverata
,
Vitreorana antisthenesi
,
V. gorzulae
,
V. uranoscopa
,
V. eurygnatha
, and
V. pa r v u l a
.
Teratohyla amelie
has green bones versus white in all species of
Hyalinobatrachium
, except for
H. taylori
from which it is distinguished by a rounded snout in profile (sloping in
H. taylori
). Males of
Chimerella
and
V. gorzulae
have humeral spines (absent in
T. amelie
).
Vitreorana uranoscopa
,
V. eurygnatha
, and
V. parvula
have a white urinary bladder peritoneum (transparent urinary bladder peritoneum in
T. amelie
).
Teratohyla pulverata
has a sloping snout in profile and scalloped, white ulnar and tarsal folds (snout rounded in profile and scalloped, white ulnar and tarsal folds absent).
Four specimens (MNCN 45959 through MNCN 45962) were collected from a small stream running through an overgrown cacao plantation, roughly
92 km
N of Bagua,
2.3 km
south (airline) from the village of Huabico (
4°57'16.59"S
,
78°12'39.92"W
,
349 m
). An additional specimen (MNCN 45958) was found in southern San Martín department,
Peru
, in a stream on the Juanjui-Tocache road, near the village of Nuevo Jaen (
7°39'16.20"S
,
76°39'24.60"W
,
591 m
). The other two specimens (MHNC 5646 and MNCN 44212) were collected on
February 1, 2007
by J. C. Chaparro, J. M. Padial, I.
De
la Riva, and SC-F at a stream crossing the road at
10 km
from Quincemil towards Puerto Maldonado (
13°12’03.6’’ S
,
70°40’28.9’’ W
;
572 m
), Provincia Ouspicanchis, Departamento Cusco. These localities narrow the distributional gap between the specimens from Cusco,
Peru
and those from
Ecuador
.
Vocalizations.
We have not been able to obtain recordings of this species, although we observed males calling in Huabico and Cusco (ET and SC-F respectively). The call sounded similar to
T. midas
, consisting of a short “chirp”, which sounded roughly similar (by ear) to the
T. midas
call described below. All individuals (including calling males) were found on the upper surfaces of leaves, roughly
2–3 m
above the stream.
Distribution and ecology.
Considering the additional records provided above,
Teratohyla amelie
is distributed in the east-Andean foothills (
349–600 m
) from Central
Ecuador
to Central
Peru
, roughly between 1° and 7° south latitude, and with an isolated record in southern
Peru
. In
Peru
,
T. amelie
has been found alongside
Cochranella erminea
.
