Remarks

• Systematics: Takagi (2017) determined that this species is identical with the form recorded by Kawai (1980) from Japan under the name A. mali. According to him, this insect is known from several scattered mountainous spots in Honsyû and Sikoku and from ‘Nana-kamado’, Sorbus commixta. This species is distinguishable from A. mali in the median trullae characterized as follows: their mesal margins are parallel and separated from each other by a space subbasally and then bent outwards and divergent (diverging from the very bases in A. mali); their blades are sclerotized broadly along the free margins in contrast with the inner parts, which are less sclerotized (uniformly sclerotized in A. mali); the horseshoe at their bases is broadly flat on the anterior margin (thickened medially to form a robust process in A. mali). Moreover, Takagi (2017) found that A. mali is variable in the occurrence of dorsal macroducts on abdominal segments.
• Structure: Adult female with prosoma swollen, distinctly broader than postsoma, rounded along free margin; prosomatic tubercles indiscernible; postsoma robust, metathorax and basal 2 abdominal segments practically same in width, pygidium broad obdeltoid, with a small recess apically; peribuccal sclerosis formed well; anterior spiracles each with a compact group of disc pores, posterior spiracles each with a smaller, much less compact group of disc pores. (Takagi, 2017)
