Spiders resembling worms: notes on Ariamnes Thorell, 1869 (Araneae: Theridiidae) with the description of a new species from Papua New Guinea and the female of A. petilus Gao & Li, 2014
The spider genus Ariamnes Thorell, 1869 of the family Theridiidae is investigated and redefined.
A new species from Papua New Guinea, Ariamnes papua sp. nov., is described based on material of both sexes.
The female of A. petilus Gao & Li, 2014 is described for the first time and newly recorded from Borneo.
The following new combinations are proposed:
- Rhomphaea birgitae (Strand, 1917) comb. nov.
- Meotipa rufopictus (Thorell 1895) comb. nov.
- Rhomphaea triangulus (Thorell, 1887) comb. nov.
Some other species currently placed in Ariamnes probably belong to Rhomphaea; these are
- A. setipes van Hasselt, 1882
- A. triangulatus Urquhart, 1887
- A. campestratus Simon, 1903
- A. russulus Simon, 1903
However, they will remain incertae sedis until the type material has been studied. The species described from Hawaii should be placed in a separate genus but remain incertae sedis for the time being.
A. cylindrogaster Simon, 1889 is recorded for the first time from Sulawesi.
