Nomenclatural act.
In
Cipola
et al.
(2018b)
Lepidocyrtus
(
Fractocyrtus
)
americanus
Cipola & Bellini, 2018
is described, but the specific name is preoccupied by
Lepidocyrtus americanus
Marlatt, 1896
, itself a junior synonym of
Willowsia nigromaculata
(
Lubbock, 1873
) (
Christiansen & Bellinger 1998: 1020
)
. Consequently,
L. americanus
Cipola & Bellini
is a junior homonym and it is here replaced (
ICZN 2000
, chapter 6, article 23.4 and chapter 12, articles 53.3, 54.2 and 60) by
Lepidocyrtus amazonaensis
nom. nov.
as
type
species of the subgenus
Fractocyrtus
Cipola & Bellini, 2018
(
Cipola
et al.
2018b
).
Etymology.
Refers to region where the species is found, Amazonas State,
Brazil
(
Fig. 19
).
Remarks.
In the original description of
L.
(
F.
)
amazonaensis
nom. nov.
some variation in the body color pattern was not reported, such as total or partial reduction of pigments on some body regions (Fig. 2), regardless of the locality of the specimens (
Fig. 19
). In addition, an observation error in this species was the number of chaetae on cephalic groove, as there are 5–6 chaetae (similar to
Fig. 14E
), that is, 1–2 additional proximal chaetae (see
Cipola
et al.
2018b: 216
).
Some variations were also observed in specimens from localities recorded here for the first time, such as Careiro Castanho and Nova Olinda do
Norte
(
Amazonas
), Melgaço, Oriximiná, Rurópolis and Santarém (
Pará
), and Boa vista. (
Roraima
). These specimens may have 14 or more spines on dens (except from Melgaço), but this appears to be a characteristic of less developed specimens (e.g. subadults). Furthermore, in specimens from these four
Pará
localities, Abd IV bears two extra mac (
E2
and
F1
) above mac
F2
and one more (
De3
) between mac
D3
and
E4
. Considering that apparently these are the only differences and that there is a small number of specimens from these localities for a better investigation, for the moment we will keep these specimens as
L.
(
F.
)
amazonaensis
.
