Eleutherodactylus juanariveroi (Plains Coqui Frog): Geographic Distribution note

Herpetological Review 53(3), 2022
forest habitats of its type locality in Barro Branco, Municipality
of Duque de Caxias, Rio de Janeiro, are today completely over-
come by the urbanization, with no recently collected specimens
(Weber et al. 2009. Check List. 5:218–221). Currently, B. secedens
is known to occur exclusively in well-preserved forests in Rio de
Janeiro, in the municipalities of Guapimirim (Vrcibradic et al.
2016. Salamandra 52:204–206) and Cachoeiras de Macacu, in the
Reserva Ecológica de Guapiaçu (REGUA; Weber et al. 2009, op.
cit.). Here, we present a new state and a new northernmost re-
cord that extends the distribution range ca. 296 km northeast in
a straight line from Cachoeiras de Macacu, Rio de Janeiro. Boana
secedens has been mentioned in a herpetological photographic
guide at Espírito Santo (Gasparini 2012. Anfíbios & Répteis:
Vitória e Grande Vitória, Espírito Santo. Fauna Consultoria em
Meio Ambiente. Vitória, Espírito Santo. 100 pp.) from the moun-
tain region of Guarapari. With no accurate locality or voucher
specimen, it is not possible to confirm its identity, which is very
similar to its congener B. pombali (Caramaschi et al. 2004. B. Ms.
Nac., Nova Série Zoo. 518:1–14), both treefrogs from B. semilinea-
ta group (Peloso et al. 2018. South Am. J. Herpetol. 13:150–169).
Our record confirms the occurrence of B. secedens at Espírito
Santo, increasing the knowledge on this rare species. This work is
part of “Herpeto Capixaba: for the knowledge and conservation
of amphibians and reptiles of Brazil”. This study was financed in
part by Fundação de Amparo à Pesquisa e Inovação do Espírito
Santo (EDITAL FAPES Nº 03/2021 - UNIVERSAL #437/2021).

First records from Guaviare and Meta departments for the
species, extending known range ca. 250 airline km south of the
nearest record in the Llanos ecoregion of Casanare Department,
from which it was previously considered endemic (Acosta-Galvis
et al. 2022. Zootaxa 5099:527–548). In addition, first records from
Guaviare River sub-basin and transition zone between Llanos
and Amazon ecoregions (UF 193039–193041), and from southern
side of Meta River (UF 193042, 193043). Elachistocleis sikuani
and its phylogenetic sister species, E. tinigua, were recently
described as new species from populations currently left as
Elachistocleis sp. cryptic species complex” (Struck et al. 2018.
Trends Ecol. Evol. 33:153–163; Acosta-Galvis et al. 2022, op. cit.).
Elachistocleis ovalis was determined to be a nomen inquirendae
(a species of doubtful name; Caramaschi 2010. Bol. Mus. Nac., Rio
de Janeiro, N. S. Zool. 527:1–30). A species of Elachistocleis was
documented from three sites in northern Guaviare Department
(Medina-Rangel et al. 2019. Biota Colomb. 20:1–7), including 1.4
and 1.5 airline km east and west, respectively, from one of the
new records of E. sikuani (UF 193040). However, Medina-Rangel
et al. (2019, op. cit.) provides a photograph of a specimen with
bright orange anterior thighs, which is characteristic of E. tinigua
(yellow in E. sikuani). The documentation of E. sikuani across a
large area within the Llanos ecoregion and transition zone with
the Amazon ecoregion (Dinerstein et al. 1995. A Conservation
Assessment of the Terrestrial Ecoregions of Latin America and
the Caribbean. World Wildlife Fund Bank. Washington, D.C.
129 pp.) in different and frequently human-modified habitats
indicates that this is a relatively common, widespread, and
adaptable species. However, additional surveys and molecular,
morphological, acoustic, and life history data are needed to
better understand the systematics and distribution of E. sikuani
and other members of the E. ovalis species complex. I thank
Rafael O. de Sá for reviewing an earlier version of this note.

Puerto Rico, extending its distribution 49.7 airline km west of
the type locality at Sabana Seca, Municipality of Toa Baja (Ríos-
López and Thomas 2007. Zootaxa 1512:51–64). This species is
listed Critically Endangered by the U.S. Fish and Wildlife Service
(United States Department of the Interior 2012. Federal Regis-
ter 77:60777–60802). We notified the local subdirector and other
personnel of this agency who gave us permission to photograph
the vouchers, and who visited the locality for corroboration and
determining conservation actions. The photo vouchers include
a 3-egg clutch on a leaf axil of the Bulltongue Arrowhead plant

(Sagittaria lancifolia), a calling male, an adult female, and a
juvenile. Another non-vouchered adult male (15.01 mm SVL)
was measured from an additional photo as a scaled reference
of size. Identifying habitats for the species is critical for find-
ing other viable populations in Puerto Rico. In the area, calling
males were heard within a Puerto Rican Royal Palm (Roystonea
borinquena) break, characterized by woody vegetation such as
Spathodea campanulata, the liana Paullinia pinnata, and Ces-
trum diurnum, Radia aculeata, Psidium guajaba, Callophyllum
antillarum, and Mimosa pigra, and in adjacent palustrine herba-
ceous vegetation composed of S. lancifolia, Typha dominguen-
sis, Achrostichum danaeifolium, Cyperus ligularis, C. imbricatus,
Bacopa monnieri, and unidentified sedges.

vidual was discovered inside a living room of a home 17 April
2022, ca. 1400 m from the first record (12.497°N, 61.4205°W; WGS

represent the first records of E. planirostris on Carriacou Island.
A population existed at least temporarily on the main island of
Grenada, with individuals collected in 1991 and 1992 that most
likely were introduced from Cuba in the 1980s (Henderson and
Powell 2018. Amphibians and Reptiles of the St. Vincent and Gre-
nada Banks. Edition Chimaira, Frankfurt am Main, Germany. 448
pp.). Whether or not E. planirostris is established on the main
island of Grenada is unknown, even though a dedicated search
there in 2016 failed to find any, so it appears to be extirpated
(Henderson and Powell 2018, op. cit.).

17 June 2022. Alexandra Lehner. Verified by Christopher E. Smith,
Rori A. Paloski, and Andrew F. Badje. Milwaukee Public Museum
(MPM VZP1067a-b; audio vouchers). New county record that
extends the species’ documented range in northwest Wisconsin
(Casper 1996. Geographic Distributions of the Amphibians and
Reptiles of Wisconsin. Milwaukee Public Museum, Milwaukee,
Wisconsin. 87 pp.). Multiple H. chrysoscelis vocalizations were
recorded on a clear, quiet evening between 2210–2225 h from
the south side of Bailey Lake. Bailey Lake is a small lake within
the northern reaches of the Northwest Sands Corridor, notably
less than one mile away from the Moquah Barrens within the
Chequamegon-Nicolet National Forest. The recording contains
at least three distinct individual H. chrysoscelis and were accom-
panied by numerous H. versicolor vocalizations; the latter tends
to be the more common species documented in northern Wis-
consin. This is the furthest north documentation of H. chrysos-
celis in Wisconsin. Hyla chrysoscelis were historically reported
by reliable herpetological sources from two townships in west-
central Bayfield County (ca. 20 km southwest), however those re-
cords were not vouchered or verified (Vogt 1981. Natural History
of Amphibians and Reptiles of Wisconsin. Milwaukee Public Mu-
seum, Milwaukee, Wisconsin. 205 pp.). Records exist in Douglas
[MPM 16596; ca. 45 km southwest] and Burnett counties [UWZM
20682; ca. 120 km southwest]; while these records are vouchered,
a physical specimen without genetic sampling leaves these re-
cords ambiguous. The nearest official published record of a H.
chrysoscelis audio voucher is in Barron County [MPM VZP998;
ca. 120 km south].
