Material examined

Holotype

PERU: Holotype (of Ocnophila mainerii Giglio-Tos, 1910 ), ♀, “Rio Chanchamayo, Peru, 1896-1898, Pesce Mainer; Holotype ♀ Ocnophila mainerii Giglio-Tos, 1910 ; Ocnophila mainerii Giglio-Tos ♀ tipo” ( MCSN). Holotype (of synonym Libethra peruana Caudell, 1918 ), ♀, “ 1800 m, 11°3’ S, 75°17’ W Greenw., N. Iconnicoff 4.12.06; Libethra peruana Caud. ♀ Type” ( USNM).

Paratype

PERU: Paratype (of synonym Libethra peruana Caudell, 1918 ), ♀, “ 1800 m. 11°3’ S. 75°17’ W. Greenw., N. Iconnicoff 4.12.06; Libethra peruana Caud. ♀ Paratype “a”; Type No. 21321 U. S. N. M.” ( USNM); Paratype (of synonym Libethra peruana Caudell, 1918 ), ♀, “ 11°3’ S. 75°17’ W. Greenw., VIII.08, C. Schunke; Libethra peruana Caud. ♀ Para-type “b”” ( USNM); Holotype (of synonym Dyme iconicoffi Caudell, 1918 ), ♂, “ 1800 m, 11°3’ S, 75°17’ W Greenw., N. Iconnicoff 12.12.06; Dyme iconnicoffi Caud. ♂ Type” ( USNM).

Other material

PERU: 1 ♂, “Peru; Ex Le Moult” ( MNCN); 1 ♂, “Chanchamayo, Peru” ( MNCN); 1 ♂, “Satipo (Dist.) Peru” ( ANSP).

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.

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.
