Description

Adult males measure 19–23 mm (0.7–0.9 in) and adult females 25–27 mm (1.0–1.1 in) in snout–vent length. The legs are short. The tympanum is large in the males, larger than the eye. Males have distinct femoral glands. The toes have rudimentary webbing. The dorsal colouration is brown, forming a distinct dorsolateral colour border with the dark brown flanks. A distinct light stripe runs from the forelimb insertion to (almost) the nostril. The throat is dark grey with a distinct pattern of white spots forming a median row. The hind limbs have dark crossbands.[4]

The male advertisement call is a rapid series of 31–36 short pulsed notes.[3]

Habitat and conservation

Mantidactylus albofrenatus is a terrestrial frog occurring in pristine or only slightly disturbed rainforest at elevations of 850–900 m (2,790–2,950 ft) above sea level. It is often found near streams.[1] Calling males have been found near streams during the daytime.[4] The eggs are presumably laid on land.[1]

It is a locally abundant species, but it is only from two localities and its population is suspected to be decreasing because of ongoing habitat loss and deterioration. It occurs in the Analamazaotra Special Reserve.[1]

gollark: I may have been somewhat unclear. I need a server for server-y uses (it runs my RSS reader and website and accursed personal integration scripts and such). This is currently a tower server, but for reasons I'd like a more compact thing.
gollark: I need to store backups and Linux ISOs and my giant datasets of memes and such.
gollark: I see.
gollark: I was wondering if there was something like the mini PC category, but with more ability to add disks.
gollark: Old servers tend to be quite good apart from largeness and power draw. There are lots of old mini PCs with good CPUs but seemingly poor disk expansion opportunities.
