Hasanuddinia sp.

( Figs 68, 70 )

Five males were recovered from a single individual of P. platyops collected from 5 k north of Wanuma, Madang Province, Papua New Guinea, by A. B. Mirza, 20. ii. 1974, BBM NG103839B.

These males could be placed in the genus Hasanuddinia because of the patterns of size and arrangement of the 13 synlophe ridges at the mid body. The specimens were of similar length (2.3–2.9 compared with 2.29–4.07) and with the same number of ridges in the synlophe, 13, as the type species, Hasanuddinia maxomyos Hasegawa & Syaffruddin, 1994 but had longer spicules (350–490 compared with 260–380) and lacked the tubercules and small rugose area on the bursal surface as described for H. maxomyos (see Hasegawa & Syaffruddin 1994a). Hasanuddinia chiruromyos Smales, 2011 , described from Chiruromys vates is a much larger worm (8050–11,700 compared with 2300–2900 long), with longer spicules (630–750 compared with 350–490) than Hasanuddinia sp. (see Smales 2011a). The partially described Hasanuddinia sp. from Lorentzimys nouhuysi Jentink differs from the Hasanuddinia sp. found in P. platyops in having 15–16 synlophe ridges in the mid body (Smales 2010). Hasanudinia maxomyos was described from endemic murines from Sulawesi, Indonesia while H. chiruromyos and the Hasanuddinia spp. occur in Papua New Guinea ( Hasegawa & Syaffruddin 1994a; Smales 2010).

A complete description of the putative new species could not be prepared from the available material because there were no female specimens and the details of the bursal rays could not be observed in the males.
