Material examined: Mahé , holotype , immature female ( ZMH ) ; Silhouette , Mt. Dauban , moss/litter 3juv. , 0 9.07.2000 , J. Gerlach leg. ( MZT AA 1.384 ) and 1f , 09.08.2000 , J. Gerlach leg. ( MZT AA 2.169 ) . Diagnosis: A. ustulata is readily distinguished from all other Seychellian spiders by having six eyes in two rows, protruding chelicerae with strong, blunt-tipped lateral bosses, and distinct tracheal spiracles close to epigastric groove. Description: Female (male unknown). This is a medium-sized (TL=4.6, CL = 2.38, CW = 1.54), dull coloured, relatively hairy species. Chelicerae black; carapace chestnut brown; sternum pale orange; abdomen dorsally dark brown, ventrally lighter; spinnerets pale yellow; legs pale orange, strongly suffused with black, especially femora which are almost totally black. Carapace densely covered with dark appressed hairs; abdomen sparsely clothed with long subdecumbent hairs in addition to the thick, appressed hairy coat; legs hairy with numerous, relatively short spines. In the middle of the epigyneal area a short, dark-coloured slightly convoluted streak. Distribution: This is an endemic species ofwhich only the type specimen from Mahé was known previously. Now also collected on Silhouette.
