Remarks

In China, the nymphs of A. obliquistriatus and A. rubromaculatus are the most difficult to distinguish, especially when they are young or typical stripes are faded. Herein, the following combination of characters are differentiable: 1) lingua is much shorter than superlinguae in A. obliquistriatus (as in Fig. 10B View Fig ), while that in A. rubromaculatus is subequal in length (as in Fig. 2C View Fig ); 2) number of comb-shaped setae on maxillae: 11–13 in A. obliquistriatus and 14–16 in A. rubromaculatus ; 3) A. obliquistriatus has lateral oblique stripes on terga I–X ( Fig. 7H View Fig ) and A. rubromaculatus has pale dots on terga I–X only ( Fig. 7K View Fig ); 4) posterolateral projections of A. obliquistriatus are moderately developed on segments III–VIII ( Fig. 7H View Fig ) but weakly developed in A. rubromaculatus (as in Fig. 7E View Fig ); 5) caudal filaments of A. obliquistriatus have brown stripes on every two or three articulations ( Fig. 7I View Fig ), but A. rubromaculatus has dark brown stripes on some articulations ( Fig. 7L View Fig ).

In male imago, the color pattern of abdominal terga and shape of genitalia can be used as valid characters to distinguish them: 1) A. obliquistriatus has unique oblique stripes on abdomen ( Fig. 12C View Fig ), while A. rubromaculatus has reddish longitudinal stripes laterally ( Fig. 12D View Fig ); 2) penial lobes of A. obliquistriatus are slightly divergent ( Fig. 13E–F View Fig ), whereas A. rubromaculatus has a distinct conelike projection between obviously divergent penial lobes ( Fig. 13G–H View Fig ).
