Definition
Semljicola alticola is a species of spider belonging to the family Linyphiidae, commonly referred to as dwarf or sheet‑weaver spiders.
Overview
The species is classified within the genus Semljicola, a group of small, ground‑dwelling spiders primarily distributed in the Palearctic region. S. alticola has been reported from high‑altitude habitats, where it inhabits meadow and shrubland vegetation. As with other linyphiids, it constructs sheet‑like webs near the ground to capture prey. Detailed distribution records are limited, and the species is not widely represented in major faunal surveys.
Etymology / Origin
The specific epithet alticola derives from the Latin words altus (“high”) and ‑cola (“inhabitant”), indicating a preference for elevated environments. The genus name Semljicola appears to be a compound referencing a geographic or personal name; however, the precise origin of the term is not documented in publicly accessible taxonomic literature.
Characteristics
- Size: Adult body length is estimated to be in the range of 2–3 mm, typical for members of Linyphiidae.
- Morphology: Like other dwarf spiders, it possesses a relatively small, round cephalothorax, a narrow abdomen, and comparatively long, slender legs adapted for navigating low vegetation and leaf litter.
- Web: Constructs a horizontal sheet web close to the ground, often accompanied by a retreat of tangled silk.
- Habitat: Recorded from alpine and sub‑alpine zones, frequently above 1500 m elevation, though exact altitudinal limits are not well defined.
- Behavior: Predatory, feeding on small insects and other arthropods that become trapped in its web.
Accurate information regarding the species’ exact geographic range, reproductive biology, and conservation status is not confirmed.
