Species within this genus are small to medium-sized (HB max 190 mm) and are characterized by external characters (Tables 4 and 5) including (1) raised tail scales, (2) one or three short hairs per tail scale, (3) a broad hindfoot, and (4) a long first hindfoot digit reaching the origin of digits 2–4. To diagnose this genus Menzies (1996) used the following set of craniodental characters: (1) broad skull with a convex profile, (2) a palate terminating before the posterior end of the molar row, (3) a zygomatic plate sloping forward at the shoulder, (4) nasal bones that do not significantly extend past the premaxillae, (5) large auditory bullae compared to species of <i>Paramelomys</i> (cf. Menzies 1996), (6) narrow and deep pterygoid fossae, (7) lateral extension of the parietal bone, (8) a wide alisphenoid strut that is fused to the alisphenoid canal and foramen ovale, (9) very well-developed lambdoid crests which curl forward over the squamoso-mastoid foramen, (10) a carotid arterial circulation that is primitive for murine rodents, as opposed to the derived pattern seen in <i>Mammelomys</i> (11) a large M 3 compared to <i>Paramelomys</i>, with an antero-internal cusp always present, and (12) only two pairs of inguinal teats (mammary formula 0 + 2 = 4). The <i>Melomys</i> population from Halmahera is characterized by small to medium body size in the genus (Weight range = 110–141 g), and has all of the diagnostic characters listed above.</p><p><b>Legend similar to that of Table 1.
