From "Entirely Yellow" to "Yellow": Ploceus holoxanthus2016-01-25 (694)
Ploceus holoxanthus was described by Hartlaub (1891) and the name means "Entirely Yellow" (Greek: holos, complete, entire; xanthos, yellow). Later this taxon was considered to belong to the Eastern Golden Weaver Ploceus subaureus, commonly known as Yellow Weaver (at least in southern Africa).
Ploceus holoxanthus, or Ruvu Weaver, is now thought to be a valid species (see news). So why was it not initially kept as a separate species?
Important changes to the taxon Ploceus holoxanthus:
So Sclater 1930 and other subsequent authors simply considered holoxanthus as a synonym of Eastern Golden Weaver.
The basic problem is that the Ruvu Weaver is similar to Eastern Golden Weaver, and few Ruvu Weaver specimens were known.
