Source-derived summary

Spiroctenus sagittarius is a species of spider in the family Bemmeridae. It is endemic to the Western Cape province of South Africa.

Distribution

Spiroctenus sagittarius is known only from the type locality at Brandvlei, Worcester.

Habitat

The species inhabits the Fynbos Biome as a ground-dwelling burrow constructor.

Description

Both sexes of Spiroctenus sagittarius are known to science. Males are pale ochraceous with the cephalic region of the carapace showing a median and two lateral well-marked fusco-olivaceous bands. The underside of the sternum, coxae, and especially the posterior femora are very pale, almost white. The opisthosoma is colored similarly to S. lightfooti, except that the black of the upper surface forms a series of well-marked obliquely transverse stripes, separated by broader parallel bands of pale yellow and united along the median line.

Females have coloration similar to males, but the carapace is faintly infuscated, except on the pale ochraceous band on each side of the dark median stripe of the cephalic portion. The chelicerae are also mostly weakly infuscated.

Editorial summary

“Spiroctenus sagittarius” enters the record as species of arachnid. Crown Archives preserves that source wording while asking what Spiroctenus, sagittarius and species can confirm, complicate or overturn.

Editorial reviewA sound reference starting point where classification, measurement and the date of the underlying evidence remain visible. The current 168-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. Its strongest next move is a source search built around Spiroctenus, sagittarius and species.
Editorial analysis

Why this record matters

“Spiroctenus sagittarius” is worth following because a concise public description often conceals a longer documentary argument. Here, Spiroctenus, sagittarius and species provides the most credible route into that argument.

Evidence profile

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 16, 2025. The linked authority identifier is Q2284068. None of the 0 selected statements returned an explicit reference.

Critical limits

Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
