Ami obscura (Ausserer 1875) new combination
Ischnocolus obscurus Ausserer 1875: 171 . Eurypelma obscurum: Roewer 1942: 240 . Avicularia obscura: Platnick 2007 .
Type: Lectotype male from Bogotá, Colombia, (Keyserling collection, BMNH 1890–7–1 –340), examined. Ausserer (1875) described a male and female but did not designate a holotype; the female has not been located.
Diagnosis: Male differs from those of other species by the reduced retrolateral keels on the palpal organ (Figs 19–20). Related with A. bladesi and the clade A. yupanqui +, in an unresolved polytomy (see Cladistics).
Remarks: This species shares the characters considered generic apomorphies; two retrolateral processes on male palpal tibia (Fig. 1), modified Type I urticating hairs, and the morphology of male palpal organ with two prolateral keels. For these reasons it is included in the genus Ami . One of us (R.B.) found a female in the collection of BMNH (1890.278) labelled: “called Ischnocolus obscurus by Ausserer, 1875 ”. It was an adult (with developed ovules) but unfortunately lacking spermathecae.
