Remarks

• Systematics: A. pseudospinosa was originally described from continental China and from Smilax and three other plants. Takagi states that his identification of specimens from Taiwan and Nepal with A. pseudospinosa (vs. the original identification as A. spinosa is not without problems since the published descriptions (Chen et al., 1980; Chen, 1983) are not sufficiently detailed (especially concerning the state of the yoke connecting the bases of the median trullae), the comparisons made by Chen (1983) among the forms associated with the different plants are incomplete and there is no mention of the designation of holotype in spite of the diverse host plants (though Smilax is named first among them). A. pseudospinosa as understood on the basis of the specimens from Taiwan and Nepal and as compared with A. spinosa is characterized in having the body less robust at full growth, the prosomatic tubercles rather prominent, the lateral macroducts moderate in size and shape, and the bases of the median trullae are connected by a slender sclerotized arch. A. pseudospinosa and A. spinosa broadly overlap in the numbers of the main wax-secreting organs, and there are no simple and obvious differences in these features between the two. They, however, show a noticeable pattern of their relative tendencies in the frequencies of the numbers of the wax organs occurring on the lateral lobes of the second and third abdominal segments. (Takagi, 2016) The view may be adopted that Tang was right enough in regarding A. pseudospinosa (which he understood through the literature) as identical with his A. spinosa (which was A. pseudospinosa in reality) and that all the records of A. spinosa made by him in continental China (Anhui; Zhejiang; Sichuan) are assignable to A. pseudospinosa. (Takagi, 2016)
• Structure: Adult female body at full growth with prosoma moderately swollen, distinctly wider than postsoma; metathorax and basal two abdominal segments roughly equal in width, the second abdominal segment a little more strongly lobed laterally; prosomatic tubercles in a small or low triangle.
