Ng et al. : Checklist <strong>of</strong> <strong>crabs</strong> <strong>from</strong> <strong>Taiwan</strong> 7<br />

Subfamily Lyreidinae Guinot, 1993<br />

Lyreidus stenops Wood-Mason, 1887 ( = Lyreiduspolitus Parisi, 1914) — Chang, 1963; Ng, Chan<br />

and Wang, 2000<br />

Lyreidus tridentatus De Haan, 1841 — Ng, Chan and Wang, 2000<br />

Subfamily Notopodinae Serene and Umali, 1972<br />

Cosmonotus grayi White, 1848 —Sakai, 1937; Sakai, 1976; Dai, Yang, Song and Chen, 1986; Dai<br />

and Yang, 1991; Ng, Chan and Wang, 2000<br />

Notopus dorsipes (Fabricius, 1798)—Ng, Chan and Wang, 2000<br />

Ranilia orientalis Sakai, 1963 — Ng, Chan and Wang, 2000<br />

Subfamily Raninoidinae Lbrenthey and Beurlen, 1929<br />

Notosceles serratifrons (Henderson, 1893) ( = Raninoides serratifrons) — present record [Fig. lc]<br />

[This species was originally described <strong>from</strong> the genus Raninoides, but is now clasified in Notosceles<br />

(see Guinot, 1993). ]<br />

Family Dorippidae MacLeay, 1838<br />

Subfamily DorippinaeMacLeay, 1838<br />

Dorippe quadridens (Fabricius, 1793) (= Dorippe dorsipes Miers, 1884, Dorippe frascone aut.<br />

partim) — Maki and Tsuchiya, 1923; Lin, 1949; Chang, 1963; Wang and Chen, 1981; Dai,<br />

Yang, Song and Chen, 1986; Holthuis and Manning, 1990; Dai and Yang, 1991; Huang, 1994; Lai,<br />

Huang and Fang, 1997; Chou, Lai and Fang, 1999 [Holthuis and Manning (1990: 18) include<br />

Lin's (1949) record <strong>of</strong> "D. dorsipes" under D. quadridens but in their discussion <strong>of</strong> D. sinica<br />

Chen, 1980, they list Lin's (1949) record <strong>from</strong> <strong>Taiwan</strong> under the distribution for this species.<br />

They did not discuss their reasons for placing Lin's record under one or the other species. Holthuis<br />

and Manning (1990: 29) comment that the distribution <strong>of</strong> the two species overlap in southern<br />

China (see discussion for D. sinica). We have examined specimens <strong>from</strong> Tahsi in northeastern<br />

<strong>Taiwan</strong> in the TMCD, NTOU and ZRC, and they are clearly D. quadridens as defined by Holthuis<br />

and Manning (1990) so it seems that the range <strong>of</strong> D. quadridens does extend into northern <strong>Taiwan</strong><br />

and possibly into southern Japan as well. In fact, Holthuis and Manning (1990: 32) had included<br />

records <strong>of</strong> Maki and Tsuchiya (1923) <strong>from</strong> Keelung in northern <strong>Taiwan</strong>. Although D. sinica has<br />

yet to be formally reported <strong>from</strong> <strong>Taiwan</strong>, its presence there is almost certain, being present in<br />

Japan and southern China. As such, it would appear that the ranges <strong>of</strong> D. quadridens and D, sinica<br />

overlap over most <strong>of</strong> southern China and probably <strong>Taiwan</strong>. ]<br />

Dorippe sinica Chen, 1980 ( = Dorippe frascone aut. partim) — Holthuis and Manning, 1990 [Fig.<br />

Id] [ Dorippe sinica is a very distinct species and can easily be separated <strong>from</strong> D. quadridens by<br />

the characters enumerated by Holthuis and Manning (1990), and in the ZRC, there are specimens<br />

<strong>from</strong> southern China which are clearly referrable to this species. Holthuis and Manning included<br />

Lin's (1949) record <strong>of</strong> " D. dorsipes" under D. sinica as well without comment (see discussion<br />

for D. quadridens) and it is on the basis <strong>of</strong> this that D. sinica is included here for the <strong>Taiwan</strong>
