Evarcha falcata
species of arachnid
Evarcha falcata is a species of 'jumping spiders' belonging to the family Salticidae.
Taxonomy
Evarca falcata (Clerk, 1757) is considered by some authors a complex of three sibling species - E. falcata s.str., Evarcha proszynskii Marusik & Logunov, 1998, Evarcha hoyi (Peckham & Peckham, 1883) - and their range is largely allopatric.
Subspecies
One subspecies is currently recognised:
Evarcha falcata xinglongensis Yang & Tang, 1996 (China)
A second Evarcha falcata nigrofusca (Strand, 1900) (Norway) was made a synonym by Breitling et al. 2016.
Distribution
This species is present in the Palearctic realm, from Europe, Turkey, Caucasus, Afghanistan, and Russia to Kazakhstan and China.
Habitat
These jumping spiders prefers dry habitats, especially the sunny edges of forests with dense vegetation, grass, shrubbery, clearings and sparse woodlands.
Description
Evarcha falcata can reach approximately a body length of 5.0–7.7 millimetres (0.20–0.30 in) in females, while males are slightly shorter, reaching about 4.3–5.9 millimetres (0.17–0.23 in). In these medium sized spiders the upper side of the cephalothorax (prosoma) of the male is light brown in the anterior half, dark brown or black in the back half. Behind the eyes and at the sides of the cephalothorax there are wide, light beige, or white stripes. The center of the abdomen (opisthosoma) is light brown, framed by black and white stripes.
Begin with the source’s own compact description: “Evarcha falcata” is species of arachnid. The dossier treats that line as a proposition to test through Evarcha, falcata and species, not as a finished interpretation.
Why this record matters
The phrase “species of arachnid” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Dec 24, 2025. The linked authority identifier is Q136182. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1757, 1998, 1883 and 1996.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
