Chiloconger Myers and Wade, 1941 Chiloconger Myers and Wade, 1941: 65 Type species: Chiloconger labiatus Myers and Wade, 1941: 66. Diagnosis . Body moderately elongate, preanal length greater than 40 % TL; tip of tail blunt and stiffened, caudal fin reduced; dorsal fin begins over posterior part of appressed pectoral fin; dorsal­ and anal­fin rays unsegmented; upper end of gill opening opposite upper part of pectoral­fin base, not enclosing pectoral fin; snout short and blunt, eye large, its diameter slightly greater than snout length; well developed, broadly rounded and elevated flange on upper lip, covering a hollowed­out area; adnasal pore present in at least one species, second and fifth infraorbital pores present, but third and fourth absent; maxillary and mandibular teeth irregularly biserial or triserial, not forming a cutting edge; lateral ethmoid process present, supraoccipital present, posterior end of urohyal simple (not trifurcate). Relationships . Smith (1989: 490) observed that the Bathymyrinae could be divided into two groups. One group contains the genera Ariosoma, Bathymyrus , and Parabathymyrus and is characterized as follows: supraoccipital bone absent, urohyal trifurcate, adnasal pore absent, third and fourth infraorbital pores present, leptocephali with lateral pigment consisting of a series of short, oblique rows of tiny melanophores on myosepta. The other group contains Paraconger and Chiloconger and is characterized as follows: supraoccipital bone present, urohyal simple, adnasal pore usually present, third and fourth infraorbital pores absent, leptocephali with lateral pigment consisting of a single series of moderately large melanophores along midlateral line. At the time, Smith had no detailed information on Chiloconger , but he assigned it to the Paraconger group on the basis of retained larval pigmentation in a small specimen. Information presented here (see below) confirms Smith's conclusion; Chiloconger dentatus has a supraoccipital and a simple urohyal. In addition, Chiloconger philippinensis, at least, has an adnasal pore, and both species lack the third and fourth infraorbital pores. : Published as part of Smith, David G. & Karmovskaya, Emma S., 2003, A new genus and two new species of congrid eels (Teleostei: Anguilliformes: Congridae) from the Indo­West Pacific, with a redescription and osteology of Chiloconger dentatus, pp. 1-19 in Zootaxa 343 on page 2, DOI: 10.5281/zenodo.156166 : {"references": ["Myers, G.
