A bstract The Taiwanese species of the family Ochodaeidae are revised. Two n e w species of the genus Ochodaeus are described: 0chodaeus sakaii sp nov., and Ochodaeus lanyuensis sp n o v ene species, 0chodaeus cooman1 PAULIAN, is recorded for the first time f rom Taiwan. A key isgiven to thespecies of thegenus Ochodaeus. Ochodaeus is a large genus in the family Ochodaeidae comprising about eight generaand 80 species in the world (SCHULTZ, 1988). Four species have so far been recorded f rom Taiwan: 0. -lcant homelas (WIEDEMANN, 1823), 0chodaeus asahinai KUROSAWA, 1968, 0. interruptus interruptus KUROSAWA, 1968, and 0. ftormosanus KUROSAWA, l968. In recent years, theauthorshad an opportunity toexaminemany specimens of thesebeetles in theauthors' collections, and also in the collections of the NationalScienceMuseum(Nat. Hist ), Tokyo, Taiwan Agricultural Research Institute, Wufeng,andNational ChungHsingUniversity, Taichung. Theauthorshavereached several conclusions fromthisexamination: twospecies, 0. asahina1and 0. xanthomelas, werenot ascertained as to their exact distribution in Taiwan. So far as t he au thors have investigated, anyspecimen of thesespecieswere not found. On the other hand, they found two newspecies and anewly recordedone, 0chodaeuscoomani PAULIAN, l945, *This study is partly supportedby the National Science Council, Taiwan, as the grant number NSC 95-28 11 -B-002-039. 300 Te ru o O c HI.

Taiwan, Japan(Yaeyamagroup of thesouthern Ryukyus). Notes. Thisspecies was described by KUROSAWA (1968, p 243) based on two male specimens from Ishigaki-jima Is., Yaeyama group of the sout hern Ryukyus, Southwest Japan, and Taiwan. As the result of theauthors' comparison ofspecimens fromtwolocalities, anydifferencewasnot foundbetween them. Theauthors, therefore, regard the Taiwanese form as belonging to thenominotypica1subspecies.
