A new genus and new records of linyphiid spiders from the Oriental Region (Aranei: Linyphiidae)

摘要

A new genus; Singatrichona gen.n., with Singatrichona longipes sp.n. as the type species, is described based on a single male from Singapore. The new genus and species presently fail to show any clear-cut relations among the known Oriental Erigoninae,but some superficial resemblance is noted to a few Palaearctic genera, especially Trichoncus Simon, 1884. Caviphantespseudosaxetorum Wunderlich, 1979 is recorded from Sri Lanka and Sumatra, Indonesia for the first time; Nasoona crucifera (Thorell, 1895)is new to the Sumatran fauna; N. orissa Tanasevitch, 2018 is new to the Sri Lankan list; and Ostearius melanopy-gius (O. Pickard-Cambridge, 1880) is new to the fauna of Java, Indonesia.
