Apterichtus klazingai (Weber 1913) Table 1 Sphagebranchus klazingai Weber 1913: 47, Fig. 9 (type locality Indonesia, Banda Sea, syntypes ZMA 104.147 ��� 48). Sphagebranchus klazingai: Nijssen et al. 1982: 10 (holotype and paratype incorrectly designated among syntypes). Apterichtus klazingai: McCosker 1977: 66. Diagnosis. An elongate species with: tail 1.8���1.9, head 12���14, and body depth 45���72 in total length; middle of eye above tip of lower jaw; 3 preopercular pores and 5 pores in supratemporal canal; teeth conical, uniserial on jaws, vomerine teeth absent; body coloration white to pale with numerous small brown spots all slightly smaller than eye, fewer and slightly larger on head, more numerous and smaller on trunk and tail; and MVF 58���138, total vertebrae 131���145 (n= 28). Size. The largest specimen examined is 440 mm, sex unknown. Distribution. Known from Durban, South Africa, north to Comoro Islands, and Maldives, across Indian Ocean to Indonesia and Australia, and in Polynesia, Micronesia and Hawaii; found in shallow sand and grass beds and coral and shell rubble bottoms to 50 m. It is possible that this species is also in Japan based on photographs taken from Okinawa (KPM-NR 6932, 10558, 36549) and Kochi. Japanese specimens however do not exist and we are not confident enough based on the photographs. Remarks. Apterichtus klazingai is identifiable on the basis of its lack of vomerine teeth and its vertebral and cephalic pore conditions. It is the most widespread Indo-Pacific species, often co-occurring with congeners including A. flavicaudus, A. moseri, and A. mysi. Not unlike those of A. equatorialis, the vertebral counts of A. klazingai range broadly; we are unable however to recognize significant geographical variation.

[[Apterichtus klazingai (Weber)]] Record of Apterichtus klazingai from Hawaii While examining Hawaiian specimens of Apterichtus in the collections of the Australian Museum, BPBM, CAS, and the USNM, we discovered 21 specimens of A. klazingai (Weber 1913) that had been collected in 20 m by the junior author along the Kona Coast of Hawaii. They differ from A. flavicaudus in vertebral counts and cephalic pores (Table 2), and in having numerous small brown spots along the posterodorsal surface of the head (Pl. 1c). They represent a new record for the Hawaiian Archipelago. Material examined of Hawaiian Apterichtus klazingai: BPBM 7906, 21(100-266), Waawaa Pt., Kona Coast, Hawaii., Published as part of John E. McCosker & John E. Randall, 2005, Notes on the snake eels of the genera Apterichtus and Ichthyapus (Anguilliformes: Ophichthidae) of the Central and South Pacific, with the description of a new species., pp. 1-11 in Zootaxa 800 on page 7

Apterichtus australis, new species, collected by dredge and rotenone in 12–100 m is described from Rapa, Pitcairn, Easter and Kermadec islands. It is closely related to A. flavicaudus (Snyder) but differs from it and all congeners in its high vertebral number, cephalic pore condition, and dentition. Ichthyapus from Easter Island and Pitcairn are recognized as I. acutirostris Brisout de Barneville. Caecula (Sphagebranchus) platyrhyncha Gosline from Hawaii is resurrected from the synonymy of I. vulturis (Weber & de Beaufort). First records of I. vulturis and Apterichtus klazingai (Weber) from Hawaii are reported.
