Remarks. This species is similar to A. laminatihumeralis sp. nov. and A. matsumotoi sp. nov. as discussed above. The specific name of this species was originally spelled as substriolata, but should be masculine since the gender of Smicromyrme was subsequently regarded as masculine following Article 30.2.4 of ICZN (1999) (Lelej & Brothers 2008). A redescription of A. substriolata was provided by Okayasu (2020). Taiwanese specimens differ from those of continental Asia and Sumatra by their entirely black legs and larger T2 spot (Fig. 14). Three females from Amami-ôshima Island are identical to the continental form, while a single female from Okinawa-jima Island is intermediate, with entirely black legs, and the T2 spot small (Fig. 15). Therefore, it is premature to describe the Taiwanese population as a separate species. Molecular experiments or discovery of the male are required to answer if these color variants are good species.
