A New Species of Hyla (Anura, Hylidae) from
Southern Minas Gerais, Brazil
ULISSES CARAMASCHI AND RENATO N. FEIO
Hyla ibitipoca, a member
of the H. circumdata
species group, is described from
the Parque Estadual do Ibitipoca, Lima Duarte, southern Minas Gerais, Brazil.
The new species inhabits gallery forests along small creeks and is characterized
by its small size, color pattern, transverse dark bars on thighs and flanks, and
small tympanum.
T
REEFROGS
of the Hyla circumdata group
are characterized by a well-developed
prepollex and dark vertical stripes on the pos-
terior surface of thighs; these features distin-
guish this group of species from all other Hyla
in eastern Brazil (Heyer, 1985). The species cur-
rently allocated to the H. circuindata group by
Frost (1985) include H. astartea, H. carvalhoi, H.
circumdata,
H. ibitiguara, H. izecksohni,
H. nanu-
zae, and H. sazimai. Heyer (1985) added H. hylax;
we also place H. inartinsi in the group.
During a survey of the herpetofauna of the
Parque Estadual do Ibitipoca, southern Minas
Gerais, Brazil, we collected specimens of a species
in the H. circumdata group that do not agree
with any of the described species. This new
species is described herein.
The abbreviations used in the account are:
SVL (snout-vent length), HL (head length), HW
(head width), IND (internarial distance), END
(eye to nostril distance), ED (eye diameter), IOD
(interorbital distance), UEW (upper eyelid
width), TD (tympanum diameter), 3FD (3rd fin-
ger disk diameter), 4TD (4th toe disk diameter),
THL (thigh length), and TL (tibia length).

on 20Jan. 1987, by R. N. Feio; MN 4711-4717,
MZUSP 66100-66101, ZUEC 6823-6824, col-
lected on 19-21 Nov. 1987, by U. Caramaschi
and R. N. Feio.
Diagnosis.
-A small species (35.5-42.7 mm SVL
in males), belonging to the H. circumdata
species
group, characterized by: 1) single, subgular vo-
cal sac; 2) small tympanum; 3) presence of trans-
verse dark brown cross bars of blotches on dor-
sum; 4) presence of transverse dark bars on
thighs and vertical bars on flanks; and 5) ab-
sence of reddish color on groin and concealed
surfaces of arms and legs.
By its small size, H. ibitipoca is distinguished
from H. carvalhoi, H. circumdata, H. hylax, and
H. martinsi (combined SVL ranging 48.0-72.0
mm; Bokermann, 1964; Peixoto, 1981; Heyer,
1985); it differs further from H. carvalhoi by its
single, expanded vocal sac (bilobed, subgular
vocal sac in H. carvalhoi), and vertical, defined
dark bars on thighs (dark bars fragmented and
irregularly arranged in H. carvalhoi). It differs
from H. circumdata by its small tympanum and
rounded subarticular tubercles on 4th and 5th
fingers (bilobed in H. circumdata).
From H. hylax,
the new species differs by its larger tympanum
and by the arrangement of the dark brown
transverse bars on dorsum; from H. martinsi, it
is distinguished by its narrower head, larger
tympanum, and more numerous and narrower
dark bars on the thighs. Hyla ibitipoca is larger
than H. sazimai (SVL 20.0-36.4 mm; Cardoso
and Andrade, 1982) and has a broader head
and narrower, more defined and numerous dark
bars on the thighs. From H. ibitiguara, the new
species is distinguished by its more slender build,
small tympanum, slightly smaller size (SVL 31.1-
44.1 mm in H. ibitiguara; Cardoso, 1983), more
defined dark bars on the thighs, and different
arrangement of the vertical bars on the flanks.
When alive, H. ibitipoca is separated from H.
nanuzae by the absence of reddish color in the
groin and concealed surfaces of arms and legs;
additionally, it has more numerous dark bars
that extend onto the anterior and posterior sur-
faces of the thighs (H. nanuzae has dark stripes
only on dorsal and dorsolateral surfaces of the
thighs; Bokermann and Sazima, 1973). From
H. astartea, the new species is distinguished by
its smaller tympanum, barred flanks, shorter
legs, and pattern of dark bars on the thighs (as
seen for H. nanuzae; Bokermann, 1967). Hyla
ibitipoca
is distinguished from H. izecksohni
by its

more robust build, smaller size (SVL 34.0-51.0
mm in H. izecksohni;
Jim and Caramaschi, 1979),
noticeably smaller tympanum, narrower head,
and presence of vocal sac and vocal slits.

Etymology.-The species is named for the type
locality in the Serra do Ibitipoca that in the
Tupi native language means bored or broken
mountain (Sampaio, 1928), probably in allusion
to the numerous caves and canyons existing in
the region.
Remarks.
-Hyla ibitipoca
was found in the region
of the Serra do Ibitipoca (Mantiqueira Moun-
tain Range) more than 1200 m above sea level.
The vegetation is characterized by rocky,
mountain fields called "campo rupestre," with
small bushes and grasses on a sandy soil. Small
gallery forests occur along creeks; the water
runs on a rocky bottom, with riffles and pools,
and the richness of organic acids imparts a dark
color to the water. The frogs were calling in
the gallery forests about 2 m from the stream.
They called on the ground litter or on small
branches, rarely more than 10-15 cm above
ground level. Several specimens were found in
small holes or in subterranean galleries formed
by interlaced tree roots; some frogs were calling
at the entrance of these galleries and, at the
approach of the observer, stopped calling and
entered the hole. The advertisement call, emit-
ted sporadically, resembles the bark of a small
dog.
In the same area H. circumdata and H. nanuzae
(both included in the H. circumdata
group) were
calling from small trees, 1-2 m above ground
level.

Bokermannohyla ibitipoca is a small-sized frog restricted to the Mantiqueira Mountain Complex, Bra-zil, and is currently categorized as Data Deficient in the Red List of Threatened Species of the IUCN. Here we report new records of B. ibitipoca throughout Minas Gerais state, Brazil and provide a distribution map of the species.
... So, we carefully decided to register this species only at the genus level. Second, both genus Adenomera and Ischnocnema present a complex taxonomy (Gehara et al. 2013, Cassini et al. 2020, and (Cruz & Peixoto, 1987) FA, CF 6, 14 Bokermannohyla circumdata (Cope, 1871) FA 13 Bokermannohyla ibitipoca (Caramaschi & Feio, 1990 molecular integrative approaches could elucidate the species complex hypothesis in both groups and arise with new candidate species or an accurate identification. For that reason, we prefer to assign both species only at the genus level. ...
... Four species had their distribution increased according to our findings in this study. Firstly, Bokermannohyla ibitipoca (Figure 3f) was described to the Parque Estadual (PE) Ibitipoca, in an area of cloud savanna and cloud shrubland with gallery forests along the creek (Caramaschi & Feio 1990, Moreira et al. 2018, and it was recorded in a temporary pond at the APABM. Although the species has already been found in PE Serra Negra da Mantiqueira (Neves et al. 2017b), PE Serra do Brigadeiro (Feio et al. 2003;Moura et al. 2012) and Serra da Boa Vista (Moura et al. 2008), is categorized as Data Deficient (Drummond et al. 2008, IUCN 2019). ...

The ecological domain of the Atlantic Forest holds a remarkable diversity of anurans with a great degree of endemism, most of which are distributed in high altitude areas, mostly represented by the mountains along the Mantiqueira Complex and Serra do Mar. Despite its biological importance, the region still shows a gap of sampling concerning the amphibians. Thus, we present the first systematic survey of the anuran fauna from Área de Proteção Ambiental Boqueirão da Mira (APABM), in the region of Zona da Mata, Minas Gerais state, Brazil. Two fieldwork expeditions were performed where fifteen sample points were inventoried through active night search and day audiovisual survey in breeding and foraging sites. The anuran fauna of the APABM presented 43 species distributed in 12 families, with the Hylidae family being the richest (17 species). Besides, four species had their distribution increased due to our findings (Hylodes perere, Physalaemus rupestris, Bokermannohyla ibitipoca and Ololygon cosenzai), all of them as endemic to the Mantiqueira Complex. This study revealed that the APABM has a great diversity of anuran species, more representative than adjacent regions such as the Parque Estadual Ibitipoca and close to the richness presented for the Parque Estadual Serra Negra da Mantiqueira. This work demonstrates the great importance of the APABM for conservation, highlighting it as an area of high diversity of the regional anuran species.

Knowledge of tadpole morphology and natural history is essential to understand and protect anuran diversity. We provide a regional taxonomic catalog of the tadpoles that occur in the Iron Quadrangle (IQ, Quadrilátero Ferrífero), a hotspot of amphibian diversity and highly threatened region in southeastern Brazil. Using a standardized methodology, free-living larvae of 67 species belonging to 25 genera and 11 families are described and illustrated, including photographs of most species in life, natural history notes, and taxonomic comments. Larvae of seven species and/or candidate species (viz., Fritziana aff. fissilis, Bokermannohyla gr. circumdata, Bokermannohyla aff. nanuzae, Pithecopus aff. rohdei, Scinax aff. machadoi, Scinax aff. perereca, and Scinax rogerioi) are described for the first time and compared to congeners. Most tadpoles of candidate species exhibited remarkable differences in morphology compared to closely related congeners, which could provide diagnostic characters for further formal descriptions. The observed material of many of the previously known tadpoles deviated from published descriptions, which might be useful in future taxonomic studies (e.g., providing characters for the taxonomic delimitation of either small-range species or widespread cryptic species complexes). Illustrated dichotomous and multiaccess identification keys are presented, allowing most species to be readily identified using reliable characters. Considering the high-level threat and huge impacts on IQ’s biodiversity and ecosystem services, particularly from mining, the results presented here provide an important foundation for research and conservation of anuran in this region.

Bokermannohyla ahenea is endemic to the Serra da Bocaina, a portion of the Serra do Mar in the Atlantic Forest of Southeastern Brazil. Little information is currently available about this species. Herein, we describe the larval morphology of B. ahenea, including internal oral features, chondrocranium, and hyobranchial apparatus, along with its advertisement call and natural history notes. This is the first description of the chondrocranium and hyobranchial apparatus for a member of the genus Bokermannohyla. The larval external morphology of B. ahenea is similar to those of other species of the B. circumdata group, but it can be distinguished from those of other species of the genus by its oral apparatus. The advertisement call of B. ahenea is complex with many numbers of notes. Also, spectral and temporal parameters of the advertisement call can be used to distinguish B. ahenea from its congeners.
... This species was described from the Ibitipoca State Park (Municipality of Lima Duarte) in southern Minas Gerais, at the elevation of 1200 m. Bokermannohyla ibitipoca is restricted to the Mantiqueira Complex area (Caramaschi & Feio, 1990), where it occurs in primary and secondary gallery forests. This species is found on the ground or on the leaf-litter near water and uses permanent streams for calling and reproduction. ...

Bokermannohyla ibitipoca is a small-sized hylid frog (males reaching up to 43 mm in snout-vent length) of the B. circumdata group (Faivovich et al. 2005). This species was described from the Ibitipoca State Park (Municipality of Lima Duarte) in southern Minas Gerais, at the elevation of 1200 m. Bokermannohyla ibitipoca is restricted to the Mantiqueira Complex area (Caramaschi & Feio, 1990), where it occurs in primary and secondary gallery forests. This species is found on the ground or on the leaf-litter near water and uses permanent streams for calling and reproduction. Here, we quantitatively describe the release call of B. ibitipoca, with comments on similarity to its advertisement call. Although used less frequently than advertisement calls, release calls have been used to diagnose species and infer phylogenetic relationships (Sullivan & Malmos, 1994; Stöck et al. 2000; di Tada et al. 2001; Wogel et al. 2004; Márquez & Eekhout 2006; Oliveira et al. 2012; Sanabria & Quiroga 2012; Grenat & Martino 2013).

Two new species of the Hyla circumdata group are described from southeastern Brazil. The type localities of both species occur in the Atlantic Forest Domain. Hyla feioi sp. nov. is described from Serra do Ibitipoca, a regional designation within the Serra da Mantiqueira, and Hyla ahenea sp. nov. is described from Serra da Bocaina, a regional designation within the Serra do Mar. Descriptions of the tadpole, advertisement call, and information on natural history are provided for H. feioi sp. nov. The advertisement call of Hyla ibitipoca is described.
... The Bokermannohyla circumdata species group comprises 15 species distributed mainly over Brazilian mountain stream habitats in Atlantic Tropical Forests. The species currently included in the group are the following (Napoli and Caramaschi 2004;Napoli 2005): B. ahenea (Napoli and Caramaschi, 2004); B. astartea (Bokermann, 1967); B. caramaschii (Napoli, 2005); B. carvalhoi (Peixoto, 1981); B. circumdata (Cope, 1870); B. feioi (Napoli and Caramaschi, 2004); B. gouveai (Peixoto and Cruz, 1992); B. hylax (Heyer, 1985); B. ibitipoca (Caramaschi and Feio, 1990); B. izecksohni (Jim and Caramaschi, 1979); B. lucianae (Napoli and Pimenta, 2003); B. luctuosa (Pombal and Haddad, 1993); B. nanuzae (Bokermann and Sazima, 1973); B. ravida (Caramaschi, Napoli and Bernardes, 2001); B. sazimai (Cardoso and Andrade, 1982). These species share the following characters: dorsum brown (live and preserved specimens), simple (not dichotomized) transverse bands on the posterior surface of thighs, single (not bifid) large and sharp prepollex, and hypertrophied forearm in adult males. ...

A new species of the Bokermannohyla circumdata group, B. diamantina sp. nov., is described from Serra dos Barbados, Municipality of Abaíra, State of Bahia, Brazil. This locality belongs to Chapada Diamantina, a semiarid region in central Bahia. This is the first record of a species of the B. circumdata group from the Brazilian semiarid. Bokermannohyla diamantina is diagnosed by the medium size (snout-vent length 47.0-51.7 mm in adult specimens); head length 2.8-2.9 times smaller than snout-vent length; tympanum medium-sized, its diameter 1.3-1.5 times smaller than eye diameter (tympanum diameter/snout-vent length 0.07); thigh and tibia lengths 0.48-0.52 and 0.49-0.51 of snout-vent length, respectively; dorsum medium to blackish brown, with weak transverse dark brown bars; flanks, anterior, and posterior surfaces of thighs with dark transverse brown stripes, lacking additional thin stripes between them; distinct vocal slits in adult males; advertisement call with 2-4 notes, and dominant frequency from 0.39-0.56 kHz.

The two species of the Bokermannohyla claresignata species group (Anura: Hylidae) have not been collected for the last four decades. It is the only species group of the hyline tribe Cophomantini that has not yet been analysed genetically. Its phylogenetic position is thus uncertain, and it has a combination of adult and larval character states that make this group a crucial missing piece that hinders our understanding of Cophomantini phylogenetics and character evolution. We obtained DNA sequences from a museum larval specimen of Bok. claresignata, using specialized extraction methods and high-throughput DNA sequencing, and combined the molecular phylogenetic results with available phenotypic information to provide new insights into the taxonomy and phylogenetic relationships of its species group. Our phylogenetic results place Bok. claresignata as sister to the Boana pulchella group, supporting its inclusion in Boana, together with Bokermannohyla clepsydra. In light of this new finding, we recognize a newly defined Boana claresignata group to accommodate these species, thus resolving both the polyphyly of Bokermannohyla and the paraphyly of Boana. Considering the phylogenetic relationships of the Boana claresignata group, we also discuss the evolution of suctorial tadpoles and mature oocyte/egg pigmentation in Cophomantini.

A NEW SPECIES OF THE HYLA CIRCUMDATA (COPE, 1870) GROUP FROM MINAS GERAIS, BRAZIL (AMPHIBIA, ANURA, HYLIDAE) A new species of the Hyla circumdata group is described from Vereda Grande Biological Station, a private reserve in the State of Minas Gerais, Brazil. The new species is diagnosed by the presence of broad head, large tympanum, dorsal surfaces grayish brown in life, and small size. Hyla martinsi, H. langei, and H. ibitiguara were not considered members of the H. circumdata species group, mainly by differences in external morphology, color pattern, and osteological characters.
