Scylaceus pallidus
(Emerton, 1882)
dwarf spider
Scylaceus pallidus is a dwarf spider in the Linyphiidae, first described by Emerton in 1882 under the basionym Tmeticus pallidus. The species is distributed across the United States and Canada. As a member of the sheet-web weaving family Linyphiidae, it constructs flat horizontal webs for prey capture. The Scylaceus comprises small-bodied spiders, with this species representing one of the Nearctic representatives of this primarily Palearctic genus.

Identification
Identification to level requires examination of genitalic structures, particularly the male and female epigyne, which provide diagnostic characters distinguishing S. pallidus from and other small linyphiid spiders. The pale coloration and Nearctic distribution help distinguish it from Palearctic Scylaceus species.
Habitat
Specific preferences are not well documented, but as a linyphiid spider it likely occupies ground layer vegetation, leaf litter, and low herbaceous strata where sheet webs can be constructed.
Distribution
Recorded from the United States and Canada. GBIF distribution records indicate occurrences in both countries, with multiple records from the USA and joint Canada-USA listings.
Behavior
Constructs sheet webs typical of the Linyphiidae—flat horizontal webs with a retreat area and threads above to intercept flying insects.
Ecological Role
in ground-layer and herbaceous stratum , contributing to regulation of small insect .
