gen. nov.

Javagone View in CoL gen. nov.

Type species: Javagone maribaya View in CoL sp. nov.

Etymology: The generic name is a combination of two words: “ Java ”, the “terra typica”, and part of the generic name Erigone . The gender is feminine.

Diagnosis: The genus contains medium-sized erigonines, with a total length of about 1.7, which are characterized by the following combination of somatic and genitalic characters:

1) Carapace unmodified, eyes somewhat enlarged, cephalic pits (= sulci) absent ( Figs 1-4 View Figs 1-9 ).

2) Legs relatively long and slender.

3) Leg chaetotaxy formula; metatarsi I-IV each with a trichobothrium; TmI about 0.31.

4) Palpal tibia simple, slightly modified ( Figs 10, 13 View Figs 10-14 ).

5) Paracymbium relatively large, L-shaped ( Fig. 12 View Figs 10-14 ).

6) Median membrane reduced.

7) Distal suprategular apophysis moderately developed (see Fig. 10 View Figs 10-14 ).

8) Embolus relatively thin, semi-looped; radix small; convector present, massive ( Figs 10-11, 14 View Figs 10-14 ).

Species included: Only the type species, Javagone maribaya sp. nov.

Taxonomic remarks: Among more than 400 known genera of the subfamily Erigoninae only 23 show the leg chaetotaxy formula coupled with the presence of a trichobothrium on MtIV. No other genera with the same chaeto- and trichobothriotaxy have been recorded from the Oriental Region, except for the monotypic genus Cirrosus Zhao & Li, 2014 , known from Xishuangbanna, Yunnan Province, China ( Zhao & Li, 2014), an area situated on the border between the Palaearctic and Oriental realms. Judging from the male palp conformation, Javagone maribaya sp. nov. does not fit into Cirrosus or any other known linyphiid genus. The peculiar structure of the male palp and the absence of the corresponding female make it difficult at the moment to evaluate the possible relationships of the new genus. It is most likely with still unknown Oriental erigonines.

Distribution: Known only from the type locality on Java, Indonesia.
