FIGURE 5. Stylised drawings. A–D. Geminofilum thailandica sp. nov. A. Dorsal tubercles of chaetigers 6–9; B. Ventral tubercles of chaetigers 6–9; C. Parapodial apendages and papillae in anterior chaetiger; D. Parapodial appendages and papillae in mid-body aposterior chaetiger; E–H. Sphaerodoridium songkhlaensis sp. nov. E. Dorsal tubercles of chaetigers 6–9; F. Ventral tubercles of chaetigers 6–9; G. Parapodial apendages and papillae in anterior chaetiger H. Parapodial apendages and papillae in mid-body and posterior chaetiger. The numbering system refers to chaetiger number, the concentric circles represent the volume of the parapodium (larger ones indicate basal and smaller distal areas) and the red axis are the imaginary lines dividing four sides of the parapodium: anterior ANT, dorsal DOR, posterior POS, ventral VEN.
