On linyphiid spiders from Java, Indonesia, with the description of three new genera and four new species (Araneae: Linyphiidae)

Abstract

Three new genera and four new species are described from Java, Indonesia: Javagone gen. nov., with Javagone maribaya sp. nov. as the type species; Javanaria gen. nov., with Javanaria gracilipes sp. nov. as the type species; Javanyphia gen. nov., with Javanyphia gede sp. nov. as the type species, and Parameioneta javaensis sp. nov. A new synonym and a new combination are proposed: Walckenaeria caobangensis Tu & Li, 2004 syn. nov. is a junior synonym of Nasoona asocialis (Wunderlich, 1974), Parameioneta Sulawesi (Tanasevitch, in Tanasevitch & Stenchly, 2012) comb. nov. is transferred from Maorineta Millidge, 1988. The linyphiid fauna of Java (including the new species described here) contains 20 species, is characterized as Oriental, demonstrates weak relations to the East Asian Palaearctic fauna and does not show any relations to the rich linyphiid fauna of the neighboring Australian Region. An annotated list of the Javanese linyphiids is given and the zoogeographical composition of the fauna is briefly discussed.
