The illustrations in Lansbury (1968)do not adequately depict the set of stout, spine-like setae at the apex of the PL in  E. bakeri, which are a good spot character for the species ( Fig. 39). In addition, this species has a row of small but evident black spines on the posterior margin of the hind trochanter that are also helpful in diagnosis and serve to distinguish it from  E. loria,  E. megalops, and  E. paramegalops, which lack such spines but are of similar body sizes, and possess geographic distributions that are overlapped by the broad range of  E. bakeri.  Ecological notes. This is perhaps the most widespread of any  Enitharesspecies occurring on the islands of Southeast Asia. It was originally described from Mindanao, with additional records from Celebes and Borneo ( Lansbury 1968, Nieser & Chen 1996). Subsequent collections have shown that the species is widespread in the Philippines, occurring on Mindoro, Marinduque, Negros, Siquijor, Biliran, and in the Camotes Group (Zettel 2003). The records presented here appear to be the first for New Guinea, Lombok, Flores, Timor, Halmahera and Obi islands, and extend the range of this species considerably to the south and east ( Fig. 63). Within the island of New Guineaitself, this species appears on the basis of present records to be confined to the Vogelkop Peninsula, occurring in both the Vogelkop Lowlands and Vogelkop Highlands areas of freshwater endemism (Areas 4 and 5) as defined by D. Polhemus & Allen (2007). Further to the east, in the main body of New Guinea, it appears to be replaced by  E. loriain similar habitats. 2610672618 [331,467,329,354] USNM J. Kansas Entomol. Soc.
