Figure 2

Comparison of skeletal characters of cleared and stained females of Danionella cerebrum, and D. translucida. Whole skeleton of D. cerebrum (a), MTD 39986, paratype, 11.5 mm SL and D. translucida (b), MTD 39992, 13.1 mm SL in lateral view, illustrating differences in relative position of dorsal and anal fins; vertical lines mark base of anteriormost and posteriormost dorsal-fin ray, respectively, in relation to anal fin. Neurocranium of D. cerebrum, MTD 39986, paratype,13.5 mm (c) and D. translucida (d), MTD 39992, 11.2 mm SL, in dorsal view, star marks ventromedial cartilage flange in (c), which is absent in (d). Tip of fused inner arms of ossa suspensoria in D. cerebrum (e) and D. translucida (f), in ventral view; note bifurcated tip in (e) and single tip in (f). Vertebrae of Weberian apparatus in D. cerebrum (g) and D. translucida (h), in dorsal view; note caudally expanded lateral process in (h), margin marked by line of grey dots. Abbreviations: in, intercalarium; ios, inner arm of os suspensorium; lp, lateral process of second vertebra; oos, outer arm of os suspensorium; r, rib; sc, scaphium; sw, swimbladder; tr, tripus.
