Stumpffia psologlossa Boettger 1881

A small terrestrial microhylid, males 14-16 mm. Colouration is variable. Back is greyish, and sometimes nearly uniformly coloured, generally with symmetrical black patches which can fuse to a teddy-bear shaped black marking. Tympanic region often with a whitish patch. Skin on the back is smooth. Tympanum is indistinct. Tibiotarsal articulation reaches the eye. Four fingers and 5 toes, without digital reduction. Males with a distinct, largely distensible, single subgular vocal sac (Glaw and Vences 1994). Call is completely different from all other known Stumpffia calls. A single note, consists of a pulsed (about 13-14 pulses) trill. Calls are arranged in series, which can last several minutes. Call duration is 700-730 ms, intervals between calls last 1700-2000 ms, call repetition rate is about 30/min, and frequency between 4.7 and 5 kHz (Glaw and Vences 1994).Most other species of Stumpffia show digital reduction and have a different call. The skin of Stumpffia gimmeli is more granular, and its call and colouration are different (Glaw and Vences 1994).Taken with permission from Glaw and Vences (1994, 2007) and Andreone and Raxworthy (2008).

Species is reliably known from Nosy Be, Nosy Sakatia, Lokobe, Benavony (Glaw and Vences 2007). It occurs from sea level up to 700m asl (Andreone and Raxworthy 2008).

Males call mainly at dusk when it is raining, sometimes also during day and night, from the leaf litter in primary and secondary forest, rarely even under single trees outside the forest. The species occurs sympatrically with Stumpffia pygmaea at Nosy Be and with Stumpffia gimmeli at Benavony (Glaw and Vences 1994).

Species is listed as data deficient in view of continuing uncertainties as to its taxonomic status, extent of occurrence and ecological requirements. It occurs in the Réserve Naturelle Intégrale de Lokobe and the Réserve Spéciale de Manongarivo. However, its forest habitat is receding due to subsistence agriculture, timber extraction, charcoal manufacture, invasive spread of eucalyptus, livestock grazing, fire and expanding human settlements (Andreone and Raxworthy 2008).

Stumpffia psologlossa is a species of frog in the family Microhylidae. It is endemic to Madagascar. Its natural habitats are subtropical or tropical moist lowland forests, plantations, and heavily degraded former forest. It is threatened by habitat loss.
