Grosphus intertidalis Lourenço, 1999

Grosphus intertidalis Lourenço, 1999: 135 .

TYPE MATERIAL. — Female holotype: Madagascar, South region, Toliara, 3.5 km N of Toliara (Coastal zone, on the beach sands), IV.1998 (N. Lutzmann), ZMH .

DIAGNOSIS. — Scorpion of medium size with a total length of 55 to 60 mm. General coloration pale yellow, without any spots. Carapace and tergites moderately to weakly granular. Pectines: pectinal teeth count 28-30 in females and 32-34 in males; basal middle lamellae of each pecten elongated and curved, widening only partially after the first internal tooth – this character is diagnostic of the species. Dorsal carinae on segments II to IV without any posterior spinoid granule. The telson vesicle is not globular in shape, but rather pear-like, particularly in males (Fig. 3C, D). Fixed and movable fingers with 10-10 oblique rows of granules.

DISTRIBUTION AND ECOLOGY. — Grosphus intertidalis was described based on a single specimen collected in the coastal zone 3.5 km to the north of Tulear (Toliara). More recently, Lourenço (2004) described a male specimen collected in the Province of Toliara, Parc National de Tsimanampetsotsa, 21.5 km NE d’Efoetse (24°0.5’S, 43°53.9’E). The specimen was found at 100 m of altitude under a stone, in a slightly disturbed zone of spiny bush. This species remains poorly known and was not represented in most recent samples coming from field inventories.
