Leptopelis brevirostris is a medium-sized Leptopelis with males having a snout-vent length of 30.7 – 43.0 mm (mean 36.7 ± SD 2.9 mm) and females with a snout-vent length of 26.7 – 65.2 mm (mean 47.1 ± SD 8.6 mm). The snout is sharply truncated in profile, relatively short, and sub-equal to the eye diameter. Males have a snout-to-eye-ratio of 0.7 – 1.2 (mean 1.0 ± SD 0.1) and females have a snout-to-eye-ratio of 0.6 – 1.2 (mean 1.0 ± SD 0.1). The tympanic annulus complete, only weakly visible in some specimens. The skin on surface of tympanum is sometimes smoother than surrounding skin in temporal region, sometimes obscured by granular skin as in temporal region, sometimes differing between left and right tympana of same individual. The skin on dorsum is smooth, shagreened or weakly granular. Males do not have distinct pectoral glands. Additionally, there is no ulnar tubercle no dermal spur on tibiotarsal joint (Bell et al. 2019). The Central African species, L. notatus (Peters, 1875), is the presumed sister taxon to L. brevirostris (Deichmann et al. 2017; Portik et al. 2019) and the two species are largely sympatric. Snout length is less than or roughly equal to eye diameter in L. brevirostris, whereas snout length exceeds eye diameter in L. notatus (Bell et al. 2019).The dorsal coloration is usually uniformly green or brown, sometimes with light-colored (yellow, brown or orange in life) spots or irregular pattern on region from top of head to sacrum [see Figure 3 in Bell et al. 2019; Plate II in Boulenger (1906); Figure 13 in Lötters et al. (2001); Figure 1 in Lötters et al. (2005); Figures 216 to 218 in Amiet (2012)]. The flank coloration is sometimes the same as the dorsum, sometimes lighter green, lighter brown, or grey, occasionally with small black spots. The ventral coloration is uniform or in combination of white, creamy- white, or yellow, sometimes with small, scattered dark spots.Other than variation in coloration (described above), L. brevirostris within a locality may vary with respect to the prominence of the tympanum (smooth skin with a visible tympanum or granular skin obscuring the tympanum), and the size and shape of the vomerine teeth (Bell et al. 2019).The species authority is: Werner F. (1898). “Ueber reptilien und batracheir aus Togoland, Kamerun, und Tunis aus dem kgl Museum für Naturkunde in Berklin.” Verhandlungen des Zoologisch-Botanischen Vereins in Wein. 48:191–213. The Central African species, L. notatus (Peters, 1875), is the presumed sister taxon to L. brevirostris (Deichmann et al. 2017; Portik et al. 2019)Some parts of the "Life History" section of this account were taken from "Treefrogs of Africa" by Arne Schiøtz with kind permission from Edition Chimaira publishers, Frankfurt am Main.

Leptopelis brevirostris is a species of “Least Concern” on the IUCN Red List of Threatened Species. The species has a large distribution, is presumed to have large populations, and can be found several protected areas including Korup National Park in Cameroon and Monte Alen National Park in Equatorial Guinea. However, the species is still threatened by loss of forest habitat due to agriculture expansion, logging, and expanding human settlements (IUCN 2013).

Leptopelis brevirostris is thought to reproduce by direct development (Perret 1966; Amiet and Schiøtz 1974) because females deposit large eggs in the soil of the forest floor, far from bodies of water (Schiøtz 1999; Plath et al. 2004; Jackson et al. 2007).In certain places males gather in fairly large numbers to call. The areas of the forest where these gatherings take place do not seem to differ from other, similar sites where the frogs are absent. Pools and puddles are consistently lacking at these sites, and since the eggs are very large (0.5 mm) and full of yolk it seems likely that L. brevirostris has forgone the free-swimming tadpole stage of development (Schiøtz 1999).The males call from branches or lianas, sometimes a leaf, normally not higher than 3 metres above the ground and apparently far from water. The voice is a rather tonal, brief "tok", repeated once or twice, sometimes three times in succession. A longer call is emitted more rarely. It is a long succession of quiet figures, followed by a normal clack (Schiøtz 1999).Unlike most species in the genus, L. brevirostris eats terrestrial gastropods (Schiøtz 1999). In a morphological study that examined more than 70 specimens, the tympanic annulus was complete in all individuals, however, the thickness and texture of the skin covering the tympanic annulus varied considerably between specimens and sometimes between the left and right sides of an individual frog (Bell et al. 2019). Loss of the tympanic membrane (and other elements of the middle ear) in anurans is often associated with a decrease in hearing sensitivity at high frequencies (>1 kHz) but this has not yet been examined in L. brevirostris. The advertisement call of males is a brief clack at 1 kHz (Schiøtz 1999).

Cameroon forest tree frog
(
Inglês
)
fornecido por wikipedia EN
The Cameroon forest tree frog (Leptopelis brevirostris) is a species of frog in the family Arthroleptidae.[1][2][3][4] It is found in southern Nigeria, Cameroon, Equatorial Guinea (including the island of Bioko), and Gabon. It is expected to occur in southwestern Central African Republic and in the Republic of the Congo, but no records have been confirmed from those countries.[1][2]
Description
Adult males measure 38–45 mm (1.5–1.8 in) and females 49–64 mm (1.9–2.5 in) in snout–vent length. The dorsum is smooth, green, beige, or grey, and either uniform or with a darker dorsal spot reaching the upper eyelid. The ventrum is white. The snout is very brief (hence the specific name brevirostris). The tympanum is present and oriented obliquely.[4]
Reproduction
The male advertisement call is a rather tonal, brief "tok", repeated once or twice (sometimes even three times). The males call at sites far from water (ponds or puddles).[4] This, together with the large (diameter 5 mm (0.20 in)) and heavily yolked eggs, suggests that L. brevirostris has direct development, i.e. there is no free-living tadpole stage. This would be different from the general pattern of Leptopelis having aquatic larvae.[4][5]
Habitat and conservation
The species' natural habitat is mature, closed-canopy lowland rainforest.[1] It appears to be a specialized snail-eater. The males call from branches and lianas, normally not higher than 3 metres above the ground, and can be abundant.[1][4]
Leptopelis brevirostris is a common species, but its habitat is impacted by agricultural expansion, logging, and human settlements. It occurs in a number of protected areas, including the Korup National Park in Cameroon and Monte Alén National Park in Equatorial Guinea.[1]

Leptopelis brevirostris est une espèce d'amphibiens de la famille des Arthroleptidae[1].
Répartition
Cette espèce se rencontre dans le sud-est du Nigeria, au Cameroun, en Guinée équatoriale, au Gabon et dans le nord-ouest du Congo-Brazzaville[1].
Sa présence est incertaine en Centrafrique.
Description
Les mâles mesurent entre 38 et 45 mm et les femelles entre 49 et 64 mm[2]. Leptopelis brevirostris a un museau très court. Son dos est lisse. Cet amphibien est de couleur verte, grise ou beige avec une tache dorsale plus sombre. Le ventre est blanc.
Cette espèce semble se nourrir uniquement d'escargots.
Reproduction
Les œufs sont plutôt grands (0,5 mm)[2].Les mâles coassent depuis des lianes ou des branches à pas plus de 3 m du sol et apparemment loin de l'eau. Le coassement ressemble à un "tok" répété une ou deux, voire trois ,fois de suite.

Опис
Загальна довжина досягає 3,8—6,4 см. Спостерігається статевий диморфізм: самиці більші за самців. Голова широка. Очі великі з доволі широкими вертикальними зіницями. Морда дуже коротка. тулуб стрункий. Лапи тонкі. На обох кінцівках є розвинені перетинки. Забарвлення спини зелене, сіре або бежеве. Черево біле.
Спосіб життя
Полюбляє тропічні та субтропічні вологі ліси. Значний час проводить на деревах. Активна вночі. В цей час часто чути доволі дзвінкий голос цієї жаби. Живиться комахами та равликами.
Розмноження відбувається на початку сезону дощів. Самиця відкладає яйця 4 мм у діаметрі, які вона носить у роті, доки не з'являться пуголовки. Після цього випускає їх у яку-небудь стоячу водойму. Тут пуголовки завершують свою метаморфозу.
Розповсюдження
Мешкає в Африці: від річки Нігер до річки Конго.
