Materials examined listed in Appendix I) Birdsong (1975) first proposed the tribe Gobiosomatini (see Smith & Baldwin (1999)) for discussion on spelling of tribe name) as a monophyletic assemblage to include 19 genera of New World gobiids based on the presence of the following characters: (1) vertebral count of 11 precaudal, 16-17 caudal; (2) first dorsal pterygiophore pattern of 3(221110); (3) scapula unossified; and (4) first 2 anal pterygiophores inserted anterior to the first haemal arch.
This group was phenetically associated with the Gobiosoma group on the basis of a dorsal pterygiophore pattern of 3(221110), vertebral count of 11+16, one epural and two anal pterygiophores anterior to the first haemal arch.
We place Antilligobius nikkiae within the Microgobius group of the Gobiosomatini based on the presence of the following characters: vertebrae 11 +16; dorsal pterygiophore formula 3(221110); anal pterygiophores anterior to the first haemal arch 2; hypurals 1-2 and 3-4 not fused; dorsal papillae row n elongate, uniting across dorsum; caudal fin lanceolate; body laterally compressed; metapterygoid process not overlapping the quadrate; and modified basicaudal scales absent.
These include a very narrow, splinter-like metapterygoid; short slender gill rakers on the lower limb of the first arch; a short papillae row b, never extending posterior of the pupil, and the modified first haemal arch.
Abdominal/caudal vertebral pattern is Type B, but haemal arch of second caudal vertebra is somewhat enlarged.
Abdominal/caudal vertebral configuration Type A, with haemal arches of first two caudal vertebrae expanded to accommodate posterior extension of swimbladder (Fig.
Vertebral transition a modified Type A, with the tenth abdominal and first caudal vertebrae (only) with a small basal haemal canal, the main haemal arch of the first caudal vertebra expanded, that of the second about half the size of the first, remaining caudal haemal arches normal; swimbladder terminates at the haemal canal of second caudal vertebra.
flavidus, we hypothesize that it fuses with the tip of the haemal spine of the second preural centrum.

Similarly, the spine of the first haemal arch should be inserted between the 3rd and 4th anal pterygiophores (Nemeth 1994).
A portion of the vertebral column containing 15-20 vertebrae, including the neural and haemal arches, was removed just posterior to the head and immediately frozen.
