Hypogeophis brevis Boulenger, 1911
Paratype: BMNH RR. 19188.8.131.52 (1910.3.18.85 yg), Cascade, Mahé; collected in 1910 by J. Stanley Gardiner.
Short caecilian species, generally less than 112 mm; tentacle closer to nostril than to eye, separated from the eye by a distance three times as great as that from the nostril; scales present; teeth in four series; tongue with narial plugs; short tail with one or two folds behind the vent, which is narrowly transverse with denticles fore and aft and larger median lateral ones bearing small anal glands; primaries not known to exceed 70 in count; distance between the eyes is less than the length from eye to snout tip; snout projects strongly beyond the mouth; first collar behind the occiput is well defined with short transverse dorsal and ventral grooves, second collar is approximately the same size with a longer transverse dorsal groove; brown with grooves slightly lighter, ventral surfaces are somewhat lighter with a yellow cream spot present at the vent (modified from Taylor 1968).
Distribution and Habitat
Country distribution from AmphibiaWeb's database: Seychelles
Typically all Hypogeophis (formerly Grandisonia brevis) species are fossorial and can be found under leaves, stones, decaying wood, and in wet soil. Distribution is thought to be limited to the availability of moist habitat rather than elevation.
Life History, Abundance, Activity, and Special Behaviors
All species of this genus are believed to be oviparous. It has been reported that H. brevis is a direct developing species.
Hypogeophis (formerly Grandisonia brevis) is known from two specimens which were collected in 1910 from Mahé island. It is recently reported from Silhouette islands (IUCN 2018) but its distribution is not well known.
