Isolapotamon (Nanhaipotamon) formosanum formosanum: Bott, 1968: 124 , gure 9.

Nanhaipotamo n formosana formosana: Bott, 1970b: 195, gure 8.

Material. One, one ( SMF 4507 About SMF ), Taiwan, Nantou, Chung-hsing Village, ded. J. K. Chia, ex coll. Tulane University collection; one ( ZMB 12528), Taiwan, Kagi .

Diagnosis. Terminal joint of rst gonopod dorsoventrally attened, broadly triangular in shape, formed by projection of mesial overlapping zone. Margins of mesial projection straight.

Type locality. Taiwan .

Distribution. Presently known only from Taiwan.

Measurements. 34.2: 27: 18.8: 9.4 ( ZMB 12528).

Remarks. The species of Nanhaipotamon can be easily characterized by diOEerences in the shape of the rst male gonopod. The mesial projection of gonopod 1 has a typical triangular shape with straight margins, and Dai (1995) showed a large number of similar species with such triangular projections. However, according to the detailed drawings of Dai (1995), the species can be separated easily from each other by the shape of the margins of gonopod 1.
