1. Pars ventralis and supraalar absent; costal extension long (about 90 µm) ( Figs 17–19 View FIGURES 17–19 ) ................................................ ................................................................................................................................ A. fortispinatus (Edwards) comb. n.

– With single or double pars ventralis; supraalar usually present; costal extension short, but false vein or dark shadow parallel to costa may give the impression of a long extension...................................................................................... 2

2. With two large pars ventralis reaching to 0.50–0.76 gonocoxite length ( Figs 32–33 View FIGURES 27–33 ) ................................................... ................................................................................................................................. A. neobilobulatus (Paggi) comb. n.

– With single, small to large pars ventralis at most reaching to 0.45 gonocoxite length................................................. 3

3. Pars ventralis small (18–36 µm long) digitiform; posterior lobe of inferior volsella well developed, reaching much further posterior than inferior volsella ( Figs 5–7 View FIGURES 1–7 )................................................... A. bilobulatus (Edwards) comb. n.

– Pars ventralis longer (45–90 µm long) digitiform, rounded or square; posterior lobe of inferior volsella absent to well developed, when well developed not reaching much further posterior than inferior volsella ...................................... 4

4. Pars ventralis much longer than broad, digitiform ( Figs 50–51 View FIGURES 45–51 ) .......................................................... A. scrotus View in CoL sp. n.

– Pars ventralis as wide as or wider than long, circular to square ................................................................................... 5
