DESCRIPTION
. — Large frog (SVL
48-59 mm
♂
,
65-78 mm
♀
), with elongate but robust body. Snout rounded, ogival. Head longer than broad (HW 30-34% SVL; HL 35-41% SVL). Tympanum distinct (TYD 8-12% SVL). Hind legs moderately long (TL 48- 57% SVL). Webbing moderate leaving up to three phalanges free; webbing formula: I 1 – 2
II
½ – 2 ½
III
½ – 2 ½
IV
2 – ½ V. Back with two dorsal-lateral folds starting from the palpebral region and ending in the inguinal region; skin of the back finely granular; some glandular warts on the flanks; breast and belly smooth.
COLOURATION
. — The dorsal colouration is olive green in life and becomes grayish in alcohol. The flanks have darker bands. In some specimens, the lateroventral part has irregularly shaped whitish and dark spots. In others, the body is uniformly olive green. The upper lip is underlined by a white band. The ventral side is white.
SEXUAL
DIMORPHISM
. — The male is distinguished from the female by a pair of vocal bags opening on each side of the throat, and the presence of humeral glands.
HABITATS
AND
DISTRIBUTION
. — This species is occurring in rainforest and forest patches in humid savannah, usually associated to flowing water. In
Togo
is mainly occurs in the ecological zone
IV
. It is frequent in the Adélé region, on the Akposso-Akébou and Danyi plateaus and on the Kouma-Konda Mountains and in Tové. The presence of the species in
Togo
has been reported by
Bourgat (1979)
,
Kulo (1980: 35)
,
BringsØe (1995)
,
Segniagbeto
et al.
(2007)
and
Hillers
et al.
(2009)
under the name
Amnirana albolabris
.
Jongsma
et al.
(2018)
however showed that West African populations are not conspecific with
Hylarana albolabris
from Central Africa. The West African species has recently been described by
Griesbaum
et al.
(2023)
. We here formally transfer it to the genus
Hylarana
as phylogenetic relationships within this genus are not resolved (Dubois
al.
2021).
