Agyneta spinifera Tanasevitch 2020, sp. nov.

Agyneta spinifera sp. nov. Figs 16-26 Holotype: MHNG; male [sample KENYA-74/06]; KENYA, Lake Naivasha, 10 km from Fisherman’s Camp, under bark and stones; 5.XI.1974; leg. V. Mahnert. Paratypes: MHNG; 1 male [sample KENYA-74/38]; Laikipia County, near Mukutan source, sifting in bushes; 22.XI.1974; leg. V. Mahnert. – MHNG; 1 male; TANZANIA, Arusha; 5.II.1981; leg. Chr. Burckhardt. Etymology: The specific epithet is a feminine noun in apposition referring to the needle-shaped tooth at the base of the embolus in the male. Description Male holotype: Total length 1.65. Carapace slightly elongated, 0.75 long, 0.38 wide, brown, with a narrow grey margin. Chelicerae 0.28 long. Legs pale brown, femora with grey longitudinal darkening, tibiae darkened distally. Leg I 2.52 long (0.65 + 0.18 + 0.68 + 0.58 + 0.43), IV 2.52 long (0.68 + 0.18 + 0.68 + 0.63 + 0.35). Chaetotaxy 2.2.2.2, prolateral spine on TiI absent. Metatarsus IV without trichobothrium. TmI 0.22. Palp (Figs 16-26): tibia apically with two projections: a small, rounded prolateral one, and a short, wide, keelshaped retrolateral one; cymbium with a small tubercle prolaterally; paracymbium relatively large, its posterior and anterior pockets poorly developed; distal suprategular apophysis with a small pit-hook; median membrane essentially reduced; lamella characteristica wide, apically notched, with small teeth/spikes on its upper edge and terminally; terminal apophysis long, widened proximally, tapered distally; embolus moderately bent, with a long, needle-shaped tooth at its base. Abdomen 0.90 long, 0.50 wide, dark grey. Female: Unknown. Taxonomic remarks: In the shape of its lamella characteristica the new species resembles A. flandroyae (Jocqué, 1985), known from Mt Karthala (1950- 2300 m a.s.l.), Grande Comoros. Agyneta spinifera sp. nov. differs in the shape of the palpal tibia (Figs 18-21 cf. Jocque, 1985: fig. 28), in the shorter and slightly uncinate pit-hook on the distal suprategular apophysis (Fig. 22 cf. Jocque, 1985: figs 29, 31), as well as by the absence of a needle-shaped tooth at the base of the embolus. Distribution: Known from Kenya and Tanzania.Published as part of Tanasevitch, Andrei V., 2020, Linyphiid spiders collected by V.
