On linyphiid spiders from Java, Indonesia, with the description of three new genera and four new species (Araneae: Linyphiidae) Author Tanasevitch, Andrei V. text Revue suisse de Zoologie 2020 2020-06-04 127 1 63 74 http://dx.doi.org/10.35929/rsz.0006 journal article 112237 10.35929/RSZ.0006 aaa42bc0-36c8-4e68-b62d-127535033b14 0035-418 5743519 FE0535B0-749B-4DBC-BA58-DF05F62EA77A Javanyphia gen. nov. Type species: Javanyphia gede sp. nov. Diagnosis: The genus contains large-sized, linyphiine-like erigonines, with a total length of 2.3-2.4, which are characterized by the following combination of somatic and genitalic characters: 1) Carapace unmodified, eyes normal in size, cephalic pits (= sulci) absent ( Figs 7-9 ). 2) Abdomen with a dorsal pattern ( Figs 7-8 ). 3) Chaetotaxy formula 2.2.1.1; each metatarsus with a trichobothrium; TmI 0.78-0.82. 4) Palpal tibia modified, with a distal claw-shaped apophysis ( Figs 21, 23 ). 5) Paracymbium relatively small. 6) Tegulum with a protegulum ( Fig. 21 ) 7) Median membrane reduced. 8) Distal suprategular apophysis moderately developed ( Fig. 25 ). 9) Embolus relatively short, slightly curved; radix wide, flat; convector absent ( Figs 22, 25 ). Etymology: The generic name is a combination of two words: “ Java ”, the “terra typica”, and a part of the genus name Linyphia . The gender is feminine. Species included: Only the type species, Javanyphia gede sp. nov. Taxonomic remarks: There are many large-sized, robust erigonines in an informal group which show the leg chaetotaxy formula 2.2.1.1 coupled with the presence of a trichobothrium on MtIV, e.g. Gnathonarium Karsch, 1881 , Gongylidium Menge, 1868 , Ummeliata Strand, 1942 , etc. In its habitus the new genus resembles these genera, and especially Tmeticus Menge, 1868 , but it has a different palp structure. The palp conformation of Javanyphia gen. nov. is characterized by a simple structure of the distal suprategular apophysis and of the embolic division, and their shapes resemble those of the Palaearctic-West Nearctic Leptorhoptrum robustum ( Westring, 1851 ) , which has the chaetotaxy formula 2.2.2.2. This similarity seems to be only a superficial resemblance, and finding a female will allow us to correctly determine the placement of the genus in the subfamily Erigoninae . Distribution: Known only from the type locality on Java , Indonesia .
