Taxonomic remarks: The new species is similar to Prosoponoides hamatum, known from northern Sumatra, but clearly differs by a twice shorter distal part of the paracymbium (not shown on palp illustrations of P. hamatum in Millidge & Russel-Smith, 1992), as well as by its thick embolus and the presence of a specific process on the convector.

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

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 well-developed, 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.

D. Burckhardt & I. Löbl [#27a].

Etymology: The species name is an adjective derived from the Latin “fovea”, meaning “a pit”, a “socket”, referring to the structure of the epigyne.

Diagnosis: The species is characterized by the unmodified carapace, by the peculiar shape of the palpal tibia, as well as by the curved shape of the convector in the male. The female is characterized by the specific structure of the epigyne, namely by the presence of two large sockets on either side of the median plate.

Description: Male (holotype). Total length 1.83. Carapace (Fig. 31) unmodified, 0.95 long, 0.70 wide, greyish pale yellow-brown, with indistinct, grey, radial stripes and darker margin; sulci absent.

Leg I 3.18 long (0.88+0.25+0.80+0.75+0.50), leg IV 3.16 long (0.88+0.25+0.80+0.75+0.48). TmI 0.62. Abdomen 1.28 long, 1.00 wide, dorsal and ventral pattern as shown in Figs 32 and 33, respectively. Epigyne (Figs 33–34, 51) with two large rounded sockets on either side of median plate. Receptacles small, rounded. Body coloration, leg coloration and chaetotaxy as in male.

Taxonomic remarks: By the unmodified carapace and by the structure of the embolic division, namely the small embolus and the shape of the convector, the new species resembles several Oriental congeners, e.g., O. cunur Tanasevitch, 2015 or O. rusticus Tanasevitch, 2015, but is clearly distinguished from those and other congeners by the structure of the epigyne, namely by the presence two large, rounded sockets on either side of the median plate.

Distribution: Known from Borneo Island, East Malaysia, and from Java Island, Indonesia.

Type species: Tegulinus sumatranus sp. nov.

Etymology: The generic name is derived from the Latin “tegulum”, the shape of which is a main character of the genus; the gender is masculine.

Diagnosis: The new genus belongs to the subfamily Erigoninae and is characterized by the following combination of characters: Rather large-sized spiders, total length 1.90–2.25. Chaetotaxy formula 2.2.1.1, all metatarsi with a trichobothrium. Carapace and palpal tibia of males modified; sulci and mastidion absent. Tegulum strongly protruded downwards; distal suprategular apophysis well-developed, long, narrow; embolus small; convector present, simple.

Species included: Tegulinus sumatranus sp. nov. and T. bifurcatus sp. nov.

Taxonomic remarks: The taxonomic position of this new genus is unclear, especially as the female is unknown. The conformation of the embolic division, namely the shape of the small embolus and the structure of the convector, somewhat resembles that of some Oriental species of Oedothorax Bertkau in Förster & Bertkau, 1883, e.g., O. meghalaya Tanasevitch, 2015 or O. stylus Tanasevitch, 2015. The discovery of congeneric females and/or other representatives of Tegulinus gen. nov. should clarify the position of the genus among the Erigoninae.
