Martin, Jon H., 2008, A revision of Aleurodicus Douglas (Sternorrhyncha, Aleyrodidae), with two new genera proposed for palaeotropical natives and an identification guide to world genera of Aleurodicinae, Zootaxa 1835 (1), pp. 1-100 : 46-47

Key to Palaealeurodicus species – puparia

1. Margin smooth; with 12 pairs of submarginal setae; penultimate pair of compound pores (abdominal segment VII) ring-shaped, without axial processes (Fig. 81) ...................................... indicus (Regu & David)

- Margin dentate ( Figs 76 –78, 80, 82, 83); without, or with only 1–3 (posterior abdominal) pairs of submarginal setae; every compound pore with an acute axial process, even if not extending beyond pore mouth 2

2. With 4 pairs of abdominal compound pores only ( Fig. 76 ). ...................................... antidesmae (Corbett)

- With 5 or 6 pairs of abdominal compound pores..........................................................................................3

3. With 5 pairs of abdominal compound pores (Figs 77, 80, 83).....................................................................4

- With 6 pairs of abdominal compound pores (Figs 78, 82)...........................................................................6

4. All compound pores similar in form and size (Fig. 83); abdominal segmentation very pronounced into outer subdorsum............................................................................................................. borneensis sp. nov.

- Abdominal compound pores of two distinctly different sizes (Figs 77, 80); abdominal segmentation less pronounced...................................................................................................................................................5

5. With anteriormost 1 pair of abdominal compound pores much smaller than cephalic pair and other 4 abdominal pairs (Fig. 80).............................................................................................. machili (Takahashi)

- With anteriormost 3 pairs of abdominal compound pores much smaller than cephalic pair and posteriormost 2 pairs (Fig. 77).............................................................................................. cinnamomi (Takahashi)

6. Marginal teeth fully separate, their sides not contiguous, margin itself coarsely and regularly dentate (Fig. 78) ................................................................................................................................... holmesii (Maskell)

- Marginal teeth with their sides contiguous, margin itself with shallow and rather irregular crenulations (Fig. 82) .......................................................................................................................... wallaceus (Martin)
