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.
