Table 9

Grammatobothus krempfi Chabanaud, 1929:377 (Type locality: Poulo Condore, Vietnam). Shen, 1983:14;? Shen & Wu, 2012:751.

Specimens examined. No specimen examined.

Diagnostic features. The following description is adapted from Shen (1983). D 81; A 66; P 14; C17; LLs 76; GR?+8.

Body ovate, greatest at near middle part of body (52.1% SL); head large (29.4% SL); upper-jaw length 10.1% SL; pectoral fin moderately long (38.7% SL); second to fourth rays of dorsal fin prolonged and pinniform; pelvic-fin rays prolonged and pinniform.

Coloration. Ocular side of body brownish, with a series of darker blotches along dorsal and ventral margins; a large blotch at curved portion of lateral line, on middle of body and in front of caudal peduncle.

Size. Reaching 99.0 mm SL off Taiwan; up to about 175 mm SL elsewhere ( Chabanaud, 1929).

Distribution. Southern Taiwan ( Shen, 1983); Vietnam (type locality).

Remarks. Grammatobothus krempfi was reported from Taiwan by Shen (1983). The specimen (NTUM 5502, sex unknown, 99.0, Tainan, 22 Oct. 1978) was identified as G. krempfi based on the ovate body shape and some anterior rays of the dorsal fin distinctly elongated. However, the specimen is not in the collection at present and therefore the identification is based on photographs. Shen in Shen et al. (1993) and Shen & Wu (2012) also reported G. krempfi from Taiwan, but no voucher specimens were provided. The picture shown by Shen in Shen et al. (1993) is clearly Bothus pantherinus , because of the absence of elongate anterior dorsal-fin rays. On the other hand, Shen & Wu (2012) showed an illustration of G. krempfi instead of providing any photo and no voucher of that illustration was mentioned.
