Remarks.
Among the above material studied, a variant morphotype of
A. marlieri
was collected from Igarapé Samã. The single male is similar in size to males described by Rippel
et al.
(2019) but smaller than specimens reported by
Ribeiro & Rafael (2009)
. There were also differences in the penis armature (
0.07 mm
length and
0.03–0.04 mm
width) hammer shape which is conical and acute, and the hooks are curved down with acute apices. Additionally, there is a pointed triple dorsal keel and small membranous vesicles in ventral view.
Anacroneuria marlieri
was previously recorded from Amazonas, Pará,
Rondônia
and
Tocantins
states of
Brazil
and our material is the first record for
Roraima State
.
