TYPE MATERIAL. — Male holotype : Madagascar , South-Western region, inland zone, between Ranohira and Llakaka , ( W. R. Lourenço ), IX.2004 , ZMH . DIAGNOSIS. — Scorpions of small to moderate size with a total length of 30 mm in total length. Several characters suggest, however, that the type specimen is a juvenile. General coloration is brown to dark brown, almost blackish with two longitudinal yellow stripes over tergites; venter yellow to pale yellow; legs pale yellow. Pectinal teeth count 36- 36 in male; basal middle lamellae of each pecten not dilated in male. Dorsal carinae on segments II to IV without any posterior spinoid granule. The telson vesicle is globular in shape. Fixed and movable fingers with 13-14 oblique rows DISTRIBUTION AND ECOLOGY. — Grosphus bicolor was only recently described from the South-Western region of the island, but from a more inland zone, between Ranohira and Llakaka, from a dry forest formation ( Lourenço 2012 ). Certain morphological characters suggest that G . bicolor has some similarities with G . grandidieri , however, distinct from this last species by the general pigmentation pattern. This species remains known only from its type locality. For more details, see the original description in Lourenço (2012) .
