Overview

Comprehensive Description

Description

M 27-30 mm, F 25-34 mm. A relatively small species with a very short snout and extended foot webbing: 1(0.25), 2i(0.75), 2e(0), 3i(1), 3e(0.25), 4i(1.5), 4e(1.25), 5(0). Distinguished by its partly paired subarticular tubercles from M. pauliani. Both M. madecassus and M. pauliani have a particular iris colour with a central darker part and an increasing number of small golden spots towards the edges.

Similar species: All other species of Brygoomantis are more or less similar, but the lack of vomerine teeth in M. madecassus is diagnostic.

Ecology

Habitat

Madagascar Ericoid Thickets Habitat

The Cryptic warbler (Cryptosylvicola randrianasoloi) is one of several bird species that are endemic to the Madagascar ericoid thickets. This ecoregion This disjunctive ecoregion includes the ericoid thicket habitats found above approximately 1800 metres on the upper slopes of Madagascar's four major massifs (listed from north to south): Tsaratanana (2876 m), Marojejy (2133 m), Ankaratra (2643 m), and Andringitra (2658 m). Tsaratanana is the most northern massif, at 14o latitude and Andringitra the most southern, at 22o latitude.

The upper montane sclerophyllous forest is dominated by plant species from the families Podocarpaceae, Cunoniaceae, and Pandanaceae, and the trees are shrouded with mosses, lichens, and epiphytes. At higher altitudes, this forest gives way to the ericoid thicket, which is dominated by the Asteraceae (Psiadia, Helichrysum, Stoebe, Stenocline), Ericaceae (Erica, Agauria, Vaccinum), Podocarpaceae (Podocarpus), Rhamnaceae (Phylica) and Rubiaceae plant families. A wide diversity of lichens and bryophytes are represented. Small, damp peat-filled depressions harbor specialized, endemic plants, while rock outcrops host a drought-tolerant flora including Aloe, Kalanchoe and Helichrysum.

Several endemic bird species such as Crossley's ground-roller (Atelornis crossleyi), Cryptic warbler (Cryptosylvicola randrianasoloi) and Yellow-bellied sunbird-asity (Neodrepanis hypoxantha) occur in the upper portions of these mountains.

Example frog species found in this ecoregion are: the  ecoregion endemic Ankafana Madagascar frog (Mantidactylus curtus); ecoregion endemic Dotted Madagascar frog (Guibemantis punctatus); the Endangered Andringitra Madagascar frog (Mantidactylus madecassus); and the Near Threatened Betsileo bright-eyed frog (Boophis rhodoscelis).

The ericoid thicket supports more than ten species of endemic and near-endemic reptiles including the geckos, Millotisaurus mirabilis and Lygodactylus arnoulti. Andringitra also has a newly discovered endemic Gekkonidae, Lygodactylus montanus. At least one amphibian (Boophis williamsi) is strictly endemic, and five other species are nearly endemic to the ecoregion. Two chameleon species are restricted to the high elevational zone of the Marojejy National Park (Calumma peyrierasi) and Andohahela National Park (C. capuroni). A new subspecies of day gecko (Phelsuma lineata) and a new species of plated lizard (Zonosaurus), as well as some anuran taxa, were discovered in the upper reaches of the Tsaratanana Massif.

Two mammals are considered endemic to this ecoregion or the ecotone between it and the upper limit of the subhumid ecoregion, both of which have been described as new genera over the course of the past few years, Monticolomys koopmani, known from the massifs of Ankaratra, Andringitra and Andohahela, and Voalavo gymnocaudus, apparently endemic to the Marojejy-Anjanaharibe-Sud massifs. The upper reaches of Tsaratanana have not been systematically surveyed for small mammals, and thus this area holds the possibility of yielding some great surprises.

Near endemic mammal species living at the middle to upper reaches of eastern mountains of the ecoregion include the Rice tenrec (Oryzorictes tetradactylus), found only in the south central highlands, Highland streaked tenrec (Hemicentetes nigriceps), several shrew-tenrecs (e.g. Microgale gracilis, M. gymnorhyncha, and M. monticola), and a species of tuft-tailed rat (Eliurus majori).
