Key to known adult males in Aclerda

1. Small convex pores absent............................................................................. 2

- Small convex pores present on at least most abdominal segments............................................... 3

2. Glandular pouches present on abdominal segment VIII, each with a single loculate pore........ A. distorta Green ( Fig. 79 )

- Glandular pouches and loculate pores absent on abdominal segment VIII but with some longer pleural setae in this position........................................................................ A. arundinaria McConnell ( Fig. 78 )

3. Style of penial sheath gradually narrowing to a sharp apex............................ A. tillandsiae Howell ( Fig. 80 )

- Style of penial sheath narrowing abruptly and then remaining quite broad to apex.................................. 4

4. Prescutum with a strong longitudinal ridge medially. Small convex pores absent from prothorax. Long setae absent from abdominal segment VIII......................................................... A. tokionis Cockerell ( Fig. 81 )

- Prescutum without a strong longitudinal ridge medially. Small convex pores present on prothorax. Long setae present on abdominal segment VIII................................................................................. 5

5. Prescutum and basisternum small and narrow............................................. Aclerda sp. B ( Fig. 83 )

- Prescutum and basisternum larger and quite broad......................................... Aclerda sp. A ( Fig. 82 )
