Differential diagnosis.
This species is similar to
A. hibisci
Huang, 1992
, but can be differentiated from the latter by median line incomplete on prodorsal shield (median line complete in
A. hibisci
), empodium 7- rayed (empodium 6-rayed in
A. hibisci
), and female genital coverflap with 10 ridges (female genital coverflap with 18–20 ridges in
A. hibisci
).
