Remarks

• Systematics: The male of A. tokionis is very similar to other Aclerda species, but differs mainly in the structure of the thorax, which has a rather small, heavily sclerotised prescutum with a strong median ridge and with a rather narrow, poorly developed basisternum, without an anterior marginal ridge. It also lacks a pair of long setae on abdominal segment VIII. (Hodgson, 2020)
• Structure: See colour photograph in Kawai (1980, Figs. 5.1, a,b).
