Geographic range

Mainland China (Guangxi), Taiwan.

New record for Guangxi.

Comments

Specimens from Guangxi Province of mainland China ( Fig. 39D–F View Fig ) have propodeal spines that are slightly broader and less developed than those of the specimens from Taiwan ( Fig. 39G–I View Fig ), and not armed at a distinct upward angle; the specimens from Guangxi (TL 2.0, ML 0.49–0.50) are also slightly smaller than those from Taiwan (TL 2.2–2.3, ML 0.55–0.60). No other major morphological difference is observed; hence, we consider specimens from Guangxi as S. takasago . This is the first record of the species within continental Asia, indicating it is not endemic to Taiwan.
