Description
Dorsal spines (total): 6-7; Dorsal soft rays (total): 9-11; Anal spines: 1; Anal soft rays: 9-10; Pectoral fin rays: 15-17; Scales in longitudinal series 27-31; Predorsal scales: 7 or fewer, extending to interorbital space; Scales ctenoid, except cycloid on isthmus; Cheek and operculum completely scaled, aboutthree rows on cheek; Body depth: 4.5-6.3 in SL; Head depth: 5.5-6.0 in SL; Least depth of caudal peduncle: 7.7-9.8 in SL; Large recurved canine tooth present at bend in dentary; Maxilla ending below anterior half of eye; Gill opening extending slightly below pectoral-fin base; No dorsal spines elongate; Pelvic fin disc reaching origin of anal fin; Pelvic frenum well developed; Caudal fin rounded: 3.45-3.85 in SL. Max. length: 6.5 cm SL. Depth range: 0 - 30 m, usually: 1 - 10 m.
Color
Ground color of dorsal part of body greenish brown, ventral whitish yellow; A black spot at base of caudal fin; Seven dark brown blotches longitudinally arranged in mid-lateral area; Black spots on cheeks and operculae, one ventral to the eye; Pectoral fins hyaline; White pelvic fins. Pigment intensity variable among localities.
Etymology
Macrodontogobius: from Greek, makros = a combining form meaning large, long, great, excessive + from Greek, odous = teeth + from Latin, gobius = gudgeon. The genus having two enormous solid incisors side by side on the vomer, extending clear across the roof of the mouth.
wilburi: I take pleasure in naming this species after Dr. Ray Lyman Wilbur, whose support made it possible for me to visit the Pelews. Ray Lyman Wilbur (1875–1949) was an American medical doctor who served as the third president of Stanford University and was the 31st United States Secretary of the Interior.
