Kalimagone View in CoL gen. nov.
Type species: Kalimagone cuspidata sp. nov.
Diagnosis: The new genus belongs to the subfamily Erigoninae and is characterized by the following combination of characters: Medium-sized spiders, total length 1.70-1.95. Chaetotaxy formula 2.2.1.1, trichobothrium on MtIV absent. Male carapace unmodified, sulci absent; chelicerae unmodified, mastidion absent. Distal suprategular apophysis welldeveloped, protruding far beyond tip of cymbium and bearing a sable-shaped process in the middle. Radix small, embolus long, relatively narrow, directed forwards. The female is characterized by the presence of a median plate on the epigyne, by short seminal ducts and relatively small receptacles situated on both sides of the median plate.
Etymology: The generic name is a combination of two words: “Kalimantan”, the “terra typica”, and a part of the generic name Erigone; the gender is feminine.
Species included: Kalimagone cuspidata sp. nov. and K. rotunda sp. nov.
Taxonomic remarks: The conformation of the male palp of Kalimagone gen. nov., namely the presence of a well-developed distal suprategular apophysis, a small radix with a long embolus, a modified palpal tibia, as well as the chaeto- and trichobothriotaxy is similar to that of some representatives of Gongylidioides Oi, 1960 , especially of G. keralaensis Tanasevitch, 2011 and G. pectinatus Tanasevitch, 2011 , both known from India ( Tanasevitch, 2011). The new genus is distinguished from Gongylidioides by the absence of a convector (a sclerite in the embolic division which is protecting the embolus), as well as by the structure of the epigyne, namely by the presence of a median plate. The shape of the epigyne resembles that of Oedothorax Bertkau in Förster & Bertkau, 1883 , but Oedothorax species have a totally different conformation of the male palp.
Distribution: Known from Sabah on Borneo Island.
