Remarks
The availability of very detailed pictures of the male
holotype
of
Dyme iconnicoffi
Caudell,
1918
in the collection of the USNM shows the specimen to bear exactly the same characteristics as the three female type specimens of
Lobolibethra peruana
(
Caudell, 1918
;
Fig. 14
) and comparison leaves no doubt that these specimens are the opposite sexes of the same species. Consequently,
D. iconnicoffi
represents the previously unknown male of
L. mainerii
(
Giglio-Tos, 1910
)
and is a junior synonym (syn. nov.). Two males were traced to the collection of MNCN, one of which is from Río Carhuamayo, the type locality of
L. mainerii
. These two specimens have body lengths of
47.6 mm
and 49.0 mm (
Figs 15–16
). A male from Satipo in ANSP is remarkable for being more slender and remarkably larger, with a body length of 58.0 mm.
Figs 14–19.

Males of
L. mainerii
resemble those of
L. panguana
Hennemann & Conle,
1907
in aspect of the body sculpturing and leg armature, but readily differ by the much smaller size as well as the considerably more stocky body and relatively shorter body segments. They are well characterized by the presence of several variably sized and irregularly dispersed yellow tubercles and nodes on the head and thorax, including the meso- and metasternum (
Fig. 17
).
As already mentioned by
Hennemann & Conle (2007: 96)
, the
type
locality “Rio Chanchamayo” presumably refers to the present Río Carhuamayo, an affluent of Río Perené which joins it near San Ramón (Dept.
Junín
), and the coordinates given for Caudell’s
type
specimens (
11°3’ S
,
75°17’ W
) refer to a place some 20 kilometres northwest of Satipo (Dept.
Junín
).
The eggs still remain unknown.
